PSK31, Raspberry Pi and HAM radio

Back to my regularly scheduled postings

A friend of mine is considering using a Raspberry Pi to decode PSK31 signals from his transiever. I searched my scrambled brain for traces of information that were planted there when I was a Junior Electrical Engineering student at UT. PSK stands for Phase Shift Keying and further investigation revealed that the 31 has to do with the ‘symbol changes’ per minute (Baud). I have not been into RF circuits much. I had enough trouble making transistor amplifiers work back then. I would find that if I put a finger in a particular place on the circuit, the amplifier would be stable. I needed a finger equivalent circuit that I could solder in place.

The way back machine is running in high gear. A junior... that probably was 1970 or 1971. 48 years ago.

APPALACHIAN DIARY, April 5, 2103, continued No writings in the back of this pictures, but they came from the same envelope of the Sugar Grove one, so I need my memory here. And what memories they bring me! Obviously, I took those when I entered the compound, after dealing with a lot of crazy security robots.  First picture. That was my working desk. SPEC-4 SIGINT / Field RTO, for SIGNAL INTELLIGENCE /  RADIO TELECOM OPERATOR. There’s still my coffee mug there... my terminal is busted. Nothing on those drawers. This bring me some memories of my training there, just some weeks before the world going nuts and entering Vault 76. I was a SPEC-4 in very short time - they frantically needed RTO’s, and being a radio amateur myself, I basically skipped a lot of training.  Sigint was fun. I had to listen to a lot of weird russian stuff, morse code, PSK31, RTTY, and try to squeeze out some sense, decrypting and brainstorming with my mates there.  Then a room, with two beds - this was a storage area. Seem that somebody tried to save some documentations here but I don’t understand the beds. No schematics, just military forms and papers. I remember I slept on that bed on the right because searching thru all that stuff took a lot of time. I felt somehow safe in there but I still remember a lot of scary sounds.  I locked the door using a file drawer. Chewed some dog food. Not bad.  Then I reached the commo area, as we called it, downstairs. Had to destroy some turrets and other crazy robots. There I found our archive. All of our schematics, manuals, procedures, and doctrine, technical and training holotapes were stored in those shelves.  A lot were missing or damaged, by water, fire, mold, gunshots, or eaten by critters. I even found rat nests in some boxes! But I managed to save a lot of nice schematics: Pipboys, civilian and military radios, tv sets, computers, terminals, radio communication devices, antennas... now I have those safe in my shelter. I even made some handmade copies of them, just to be safe.  Also got many tech manuals about a lot of those equipments.  At that time I was thinking “hey - I can start a business here, a repair shop of some sort! I can build and fix stuff! Let’s try this...” And so I started my journey as a wasteland repair shop / technician / whatever.  Filled my backpack and a sack with everything valuable - stashed some copies in some hidden drawers as a safe backup, and di di mau (my MSG said that for “hurry up and get the fuck out!” - I think it’s an old war slang of some sort from the 20th century, I never understood) back to my camp with everyting. Got also some holotapes! My pipboy can read them but it’s not the best for checking schematics and complicated tech notes. Some are damaged but I got some blank holotapes to use for spare parts. The duplication / repair machine wasn’t working... PAPER IS HEAVY! PS Yes, I also got a lot of typewriters servicing manuals and mechanic specifications :)  #fallout76 #roleplay #diary

Joe Taylor’s Amateur Radio by Barry Wright - KA7V With Input from SM2CEW

At one time the history of the American Radio Relay League (ARRL) and its creator Hiram Percy Maxim were always mentioned prominently in the ARRL Handbook. This is no longer the case. You may do a search on any recent edition and see what you find.

Mr. Maxim was the individual that founded the ARRL in 1914 and profoundly influenced what amateur radio is today. The most important mode of communication at the time was continuous wave or CW. This is commonly known as the Morse Code invented by Samuel Morse. When I obtained my first amateur radio license in 1958 the ability to send and receive the Morse Code at 13 words per minute was a requirement for obtaining a license. The most common license at that time was the General Class License and it provided all privileges for amateur radio operation.

Amateur radio operation was not unique to the United States and was and remains to this day popular all over the planet.

As some point during the 1970s the ARRL decided that to operate on all modes on all bands a higher status license was required. This was the Amateur Extra Class license. To obtain this license one had to demonstrate knowledge of radio frequency communication including electronic fundamentals and all of the rules and regulations that were required to legally operate an amateur radio station. In addition, the Morse Code requirement was set at 20 words per minute. Since I had operated CW almost exclusively during my amateur radio career, 20 words a minute was not a problem. The technical exam for the Amateur Extra Class License in 1980 was comprised of multiple choice questions. When I first obtained my license in 1958, this wasn’t the case. At that time, one might be asked to draw the circuit diagram for a Colpitts oscillator or define the differences between Class A,B, AB and C transmitter operation. These classes of operation were defined as their conduction state. You can find a lot of information on amplifier conduction states on the internet.

I will say that Class A amplifiers were considered linear where the single output device conducts through a full 360 degrees of the output waveform. When one is listening to recorded music, for example, this was considered ideal. However for operating radio transmitters, the efficiency of Class A operation was not very high and greater amplification of a transmitted signal was needed. A form of linearity was still considered desirable however, especially for voice communication. One could run CW operation in Class C. These were non-linear modes and were most suitable for CW and similar modes like RTTY and frequency modulation or FM. Again if you want more information about this subject matter, the internet is full of such material.

These techniques were accepted from the beginning of radio frequency operation through the end of the 20th Century. I saw no need for anything else.

There were additional codes besides CW that were employed by governments, for example, that wanted the content of their communications kept secret. During the 2nd World War, the Germans and Japanese both had encryption algorithms that made it difficult to easily decipher their messages. The United States military could translate the Japanese code into understandable English and the Allies did the same for the code used by the Germans.

There were algorithmic requirements for these codes or they would be so simple to translate that they would become useless for any method of encryption. The Morse Code on the other hand was simple to the point where a moderately intelligent individual could easily translate CW into English words themselves.

Modes like RTTY or Radio Teletype and psk31 had a level of complexity that made it difficult if not impossible to translate without the assistance of a decoding device. Decoding devices are now known as computers.

So there were several modes of operation for amateur radio operation but it was still necessary to be able to send and receive the Morse Code to obtain an amateur radio license that granted all operational privileges. The assumption by many was that the technical aspects of any exam could be memorized from a text book but one couldn’t fake knowledge of CW. CW was the ultimate indicator of anyone’s acceptability to join the amateur radio community.

The importance of CW can be seen in this example. One of the great achievements of radio communication was the reflection of a radio signal off the moon and its reception back on the earth. This was first done by the U.S. Army on January 26 1946 and was later done by amateur radio operators. You can read more about the amateur radio moon reflection project here:

The first Amateur Lunar tests & contacts.

It became easier over the years as amateur radio operators accumulated wealth and antenna and preamp design became more sophisticated. By the early 1970s many amateur radio operators were able to send and receive signals via “moon bounce” or earth-moon-earth (eme). This was first accomplished by Morse Code. So Morse Code once again was essential to amateur radio.

For some reason however the Federal Communications Commission, with the suggestion and support of the corporate lobby previously known as the American Radio Relay League, removed all Morse Code requirements for all amateur radio license classes in 1991. You can read about their pathetic excuses in this piece: It Seems to Us “Morse” by David Summer.

There were members of the amateur radio community that did not think this was a good idea. See, for example: Maybe Nothing Will Save Amateur Radio - Original Author Unknown

After all, for amateur radio to remain a civilized process some degree of proficiency in a set of skills was necessary. I can only speculate why the ARRL lobbied the FCC to take this step in reducing the requirements for obtaining an amateur radio license, but the general assumption was that the ARRL wanted the number of amateur radio operators in the world to increase. It is perhaps coincidental that the greater number of amateur radio operators that existed, the larger the market would be for amateur radio equipment.

Well since making legitimate contacts by modes such as single sideband could still at times be difficult, a new mode of communication that had a much higher probability of success was desirable. After all, who would want to spend thousands of dollars on equipment that they couldn’t use to make contacts with others that had also spent several thousands of dollars for equipment designed for the same purpose. Or so the theory went.

The unasked question became was another mode possible that would make completing an amateur radio contact (also known as a QSO) a slam dunk? As it turned out, someone was waiting in the wings, so to speak, to accomplish this.

A particular amateur radio operator whose call sign is K1JT who possessed seemingly impeccable credentials, decided on his own perhaps to fill the void to produce a mode of operation that was really easy to make contacts with. This mode was known as WSJT. As defined by its inventor the WS part meant Weak Signal and the JT part was the suffix of his call sign (K1JT). No modesty there at all.

The propagation modes this software was originally designed for was Meteor Scatter, Tropo Scatter and moon bounce. The stated intention of this software was to make these communications modes “easier” and more accessible to amateur radio operators that couldn’t afford large antenna arrays and expensive equipment. However the laws of physics begin to impinge here. It could be determined through mathematically based limitations that a certain level of technology was required to complete an eme contact. And no computer software could change that. Nevertheless Joe Taylor tried.

The WSJT program became so successful, some might say simple, that some of us that were almost lifelong amateur radio operators considered it too easy. And questions arose about the methods used by this code to communicate. I would complete Meteor Scatter contacts, for example, and when completed, I would comment that “this is too easy.”

One of these methods that made the JT software so easy was called “deep search” which is most applicable to the JT65 modes. This wasn’t a deep search of the cosmic microwave background radiation that was created at about the same time as the universe in the so-called “big bang” to detect a radio signal. Instead “deep search” was a elementary search of a database. This database consisted of amateur radio call signs and that is all that was searched for. It has been demonstrated by SM2CEW that if one tried to use WSJT to complete a moon bounce contact, if one of the participant call signs were not in the database supplied by the WSJT installation or if it were altered, there wouldn’t be a contact. The database is call3.txt.

To sum up what has been said to this point, communications off the moon was first accomplished by amateur radio operators in 1960. The mode utilized was CW. Single sideband contacts became feasible sometime later. As previously mentioned, to complete a contact, certain well defined information had to be sent and received by both operators attempting the contact. This required a certain bandwidth or data banwidth. The data bandwidth required to exchange this information was finite. Anything with lower bandwidth wouldn’t work. That is to say, exchanging the necessary data for a complete contact with a data bandwidth with less information, i.e. bandwidth, that the minimum bandwidth could provide was impossible. To say it differently, the WSJT bandwidth wasn’t adequate to complete a previously defined contact or QSO.

Unless one is educated in advanced mathematics and cryptology one generally lets the experts define the terms of the debate that establishes this concept.

These are links to the articles that question the legitimacy of the various forms of WSJT and its ever evolving forms:

A Comment on Joe's Paper „How Many Bits Are Copied in a JT65 Transmission?“

Communication using WSJT, JT65 ”Deep Search”

Deep Search Cannot Communicate Callsigns

I had an experience myself where the amateur radio station that wanted to work “my state” which is Oregon, became really upset when I didn’t apply the QSO criteria that are demystified in the articles cited above. The result is that he will never work Oregon on 432 MHz for the rest of his life. See, for example:

Communication via Moon Reflection by Radio and by Internet Part 1 by Barry Wright KA7V

This is a 3 part series but there are plentiful links to all parts in part 1.

To summarize for the benefit of those that dislike reading technical articles, there aren’t enough differentiated bits in the WSJT algorithm to allow the minimum transmission and reception of information required for an amateur radio contact to be completed. In other words WSJT is inadequate. Actually it is more than that, it is a fraud: it couldn’t be used to complete an amateur radio contact by exchanging the required data.

There is another paper that outlines the basis of modern communication theory which is extremely useful in this discussion.

A Mathematical Theory of Communication by C. E. Shannon

This article is way beyond the perceptible abilities of Joe Taylor to comprehend.

So sum it up one more time, Joe Taylor’s schemes are nothing more than propaganda, endorsed by the ARRL and other corporate lobbies, that are devoting enormous degrees of time and resources to convince those who lack the ability to make decisions for themselves that Joe Taylor’s algorithms are sufficiently robust to communicate radio messages between humans fulfilling the requirements for a contact. See above. I realize that my case is made and that I could stop here.

However if you search the internet for anything critical of Joe Taylor, K1JT, you will not find it. The level of propaganda supporting Joe Taylor is that profound. One has to look in scientific journals to find criticism of his methodology.

So this is Joe Taylor’s vision for amateur radio going forward. Not only does he want his concoction to be the only mode on VHF/UFH Meteor Scatter, Tropo Scatter and eme communications, he wants his software to become the dominate mode for high frequency communications as well. To accomplish this, he wants to rid the spectrum of other modes, like CW, and take control of frequencies these modes have historically used.

SM2CEW has reviewed what I have written and has suggested that the following points be added. I agree, so here they are:

1. It is essential and critical that each user of the popular WSJT protocols like JT65, FT8 (FTx) and Q65 protocols keep their PC clocks synchronized to the millisecond. Therefore everyone have to either be connected to an Internet time standard, or use their own Rubidium clock. If your PC is out of sync, you will not be able to decode messages. Traditional modes do not need this critical time sync and are therefore more reliable in every aspect of the word, especially during emergencies or when other resources are not available. 2. Not only is there a critical demand to be precisely synchronized in time, you also need to find out what protocol and what specific transmit/receive period length the other party is using plus which one is his transmit period. This his NOT something that the software will find out for you, you need to know this before hand to be successful. So to be successful you need another communication channel, parallel to the radio path to find this out. Or rely on some shady type of common consensus on how to operate which has proven to be very difficult, if not impossible 3. Random length text is not possible to convey over the radio, except for a very restricted 10-15 character message that will not be decoded unless signals are strong and the PC is exactly synchronized in time. In the case of an emergency, where amateur radio is often called upon, the ability to send any type of message has been the most important part of radio communications since radio was invented. As for ham radio, transmitting messages containing more than just two callsigns has always been the most important part of our hobby. Hence the earlier requirement at the exam to be able to copy CW messages 3-6 minutes long or more without any help of machines or computers. 4. Amateur radio in the form of WSJT totally rely on other resources like Internet access and computers just to be able to convey the most simplistic amount of data - two callsigns and a report. To see this as the future of amateur radio, just because one man is proud of his achievements, is nothing but a disgrace to everyone who uses traditional amateur radio to converse with other fellow radio amateurs. Or pass vital and important traffic when called upon for some reason. 5. There is also a big risk here as people anticipate that WSJT can be used successfully in an emergency situation. There will be a rude awakening for people who market the software as a robust and capable way of radio communication. Nothing could be further from the truth. Through the years amateur radio has over and over again proven itself to be the most important communication link during and immediately after disasters. Phone and CW operators have given us a strong reputation as a vital resource during such conditions. A WSJT operator is in NO way to be considered a resource during a disaster because his hands are tied, if he lacks the Internet he can't even convey his callsign and a report. And he can of course not send a highly important 300 character emergency message either.

The point that Peter is making is that WSJT/JT65 and other algorithms intended to replace CW are not conversational. All that is exchanged is a specific predetermined message that is very short in length and has to be synchronized in time by both participants. There is no conversational aspect to contacts when the K1JT methodology is used. And it is becoming so wide spread with no critical analysis that the effect it is having on amateur radio communication makes it impossible to tell your QSO partner what the weather is like or what equipment and antennas are used. Amateur radio communication has never been reduced to this and before K1JT’s propaganda assault was implemented, it would have been unthinkable.

If you want to send soundcard CW, and there can be reasons for doing that, there are programs like CwType that allow an exchange of information by Morse Code that is typed on a keyboard. CwType has memories and anything that can be typed on a keyboard can be sent. If one’s hand is injured, for example, and a person is unable to use an iambic keyer, CwType would be a good tool to use until one has recovered from an injury. Joe Taylor's propaganda campaign should be brought to the attention of the governmental agencies responsible for enforcing the American's with Disabilities Act.

What I am saying is that what you type is what is sent. The CW message is not predetermined in length and can be as long and creative as the sender wants. CwType can be download and easily installed. The site for downloading is DXSoft https://www.dxsoft.com/. There is an RTTY program there as well. All of these programs are quite different that anything created by Joe Taylor.

This video documents the Dutch Grand Prix Skating Race. The opening is one of the most stunning scenes on the planet. The ice, the sky, the snow, everything is incredibly beautiful. About 700 people from The Netherlands were in Sweden at the time of this recording competing in outdoor ice skating on the ice in Lulea Harbor Sweden to watch a Dutch Grand Prix skating race. The Dutch can not do so at home any more because of global warming. Their canals never freeze anymore. This is something that Joe Taylor could never appreciate. He lacks the ability to tell the difference between what is beautiful and what isn’t.

He doesn’t believe in sharing except for his own personal gain. He has ulterior motives for everything he does. He is less than human.

This is the kind of person the ARRL and other corporate lobbies are giving the future of amateur radio to.

You should remember that the current generation of CW operators may be the last. I got started when I was very young. I’m now 75. Nobody knows how much longer CW operation will last. However I can tell you that a CW exchange between two stations can be very brief. If you want the other operator’s name, you could simply send “name?” I’ve used examples of exchanges like this in contests that I have participated in. This amount of information could not be exchanged in such a short amount of time by any other mode.

In conclusion, if you don’t want a future without CW, time is running out for you to act.

Buying an SDR?

Please consider the following makers of SDRs ahead of any others. These manufacturers have gone the extra mile to see that SDR software developers such as myself are provided with working SDR samples, technical support and interfacing data:

• AFEDRI (822, 822x) • AirSpy (HF+) • Andrus (MK 1.5) • Funcube (pro, pro plus)

the documentation carefully. Take advantage of the extensive index. If you can’t find something in the index, please let me know. I try to keep the documentation up to date. It’s no trouble at all to add index entries, and generally speaking, I’m willing to expand the main manual itself if you find something I have not covered yet. Recent changes to the documentation may only be found in the beta documentation until a version update of the entire package is made; this is where to look if you ask me to add something, it’ll appear there first.

Note to Windows OS users: Only run SdrDx and SwDb out of the folders I supply them in. Don’t stick the executables somewhere else. That way lies madness. MaDnEsS!

For Developers (and those who would encourage developers)

In order that SdrDx is able to support additional USB-based SDRs, a protocol-compatible server must be written by the SDR vendor or a third party. You can use this fully functional RTL USB-to-network server as a starting point — it does everything you need to do to talk to SdrDx. SdrDx will work with any SDR or SDR network server that acts like the sample server software; if you need to extend the network methods, for instance to control features unique to your SDR, let me know and I will do my best to support those extensions. However, note that I require that the actual SDR be provided to me for development and testing of those extensions.

Likewise, if you’re considering a new SDR design where you plan to have an Ethernet connection as one of, or the only, method of communication to the host computer, ideally it will be compliant with those protocols. If it is, it will “just work.” If it isn’t — it won’t, and software support for your design will be considerably more limited. Examples of such well-designed SDRs include the Andrus MK 1.5 and the AFEDRI, as well as the SDR-IQ via its network server applications. And of course all the RFSPACE networked SDRs.

If you’re looking for something to do, many USB-based receivers are desperately in need of precisely such a server. No, I don’t write these servers. I spend what time I have adding radio features to SdrDx. However, here is GPL’d source code for an SdrDx-compatible USB-to-Network server for the RTL 'stick' SDRs that can be refactored to support other USB devices. All you need to do with regard to SdrDx is tell me what device name you will use with the server (it currently reports in as 'RTLSVR', you need to pick a name for the device you’re supporting, and tell me what it is.)

For Everyone:

Is my SDR already supported? The answer is here: Check this list.

Wideband RF Recordings — these are useful if you’d like to try out SdrDx but you don’t have an SDR yet. You can start SdrDx, press '>play (click that link, then look for the green button) and then enjoy receiving the described band, event, etc. You can tune within the bandwidth of the recording. So for instance, if you play the 6100 kHz recording, which is 200 kHz wide, you can tune from 6000 kHz to 6200 kHz — most of the 49 meter band! Just download and install SdrDx, then the file of interest, start SdrDx, press > and select the file (if it’s zipped, you have to unzip it first.)

Help for AFEDRI (preliminary)

People have been having problems getting the AFEDRI to work with SdrDx; I’m not sure why, but here is some information on what I did to get mine going.

Before you start, make sure you’ve set the audio output within SdrDx using to the correct device. If this is not set correctly, SdrDx cannot run.

Now as to the AFEDRI itself: First of all, I could not make the AFEDRI’s DHCP settings work at all. I contacted Alex, the designer, and after quite a few emails back and forth, he suggested a static IP configuration. I set that up, got it working on my normal network, and then connected it to my 2nd ethernet port on the Mac (this is under OS X 10.6.8) under a second network of 192.168.10.1; this involved some fairly annoying screwing around with the OS X configuration files. I never did get the DHCP to work, though some SdrDx users have. So I strongly suggest you set the AFEDRI up using a static IP; I think there may be some fairly severe bugs in the AFEDRI’s DHCP handling, or at least, ways it can be set up that simply don’t work. Other SDRs, such as the Andrus MK 1.5, configure using DHCP no problem, so it’s definitely something unique to the AFEDRI.

Having said that, it could very well be something I did in the configuration utility of the AFEDRI; the version I had only provided a Windows-only program, and I only fired up the laptop to work with it until I got it to work in general, and never looked back. Running windows give me hives. Still, I know for sure you can get the AFEDRI working with OS X — the AFEDRI is the SDR I’ve been using for quite a few months now; it’s a great SDR. I would expect results to be similar for Windows, that is, static IP will definitely work, and DHCP might not.

System Requirements

SdrDx and SwDb for the Mac require an Intel CPU, running Snow Leopard 10.6.8 or later.

So far, I have numerous third-party reports of SdrDx working under 10.6, 10.7, 10.8, 10.9, 10.10, 10.11 10.12, and 10.13.

Users of 10.11 through 10.13 report mixed results, under these OS X versions, USB server based SDR users are facing driver installation and activation problems, and tooltips and drop-down menus are blank; Apple’s gone and broken perfectly stable APIs again. Steps required to compensate for Apple’s idiot USB shenanigans are in the docs under new installs. No fix in known for the tooltips issue at this time.

There are two tricks required as of 10.9 and later:

First, you need to turn the “App Nap” feature off or when SdrDx is not the front window, OS X will put it to sleep, which will break it. Right click on the SdrDx app icon, select “info”, turn off App Nap, and close the info window. If you’ve got an SDR-IQ where the server runs under 10.9, you’ll need to do the same thing to the server application. Note: I suggest the very first thing you do with any application you install is turn off App Nap — it’s one of Apple’s worst ideas ever. That’s all there is to that.

Second, under 10.9 and later, for users of the SDR-IQ, Apple thoroughly broke the USB driver that is required for the SDR-IQ and SDR-14 (and possibly the CloudIQ — anyone have a CloudIQ running?) So in order to use the USB driver in the SDR-IQ/SDR-14 server application instead (so the USB to Net server will work), you need to enter the following in a shell right after you boot your machine…

sudo kextunload -b com.apple.driver.AppleUSBFTDI

Rtl-sdr For Mac

…it’s not sticky, so you’ll have to do this every time you reboot your Mac.

And of course SdrDx requires an SDR as well if you want to receive live, although it can play back pre-recorded files without an SDR; in the specific cases of the AirSpy HF+, RTL SDR, SDR-IQ and SDR-14, you’ll need to use one of the server applications that puts these SDRs on the network. SdrDx’s support of RFSPACE SDRs and compatibles, and near-compatibles, is only via network connections, SdrDx does not directly interface with the USB connection of the SDR-IQ.

For the Mac, I am presently designing and testing and compiling under an OS X 10.6.8 (Snow Leopard) virtual machine (VMWARE) running under OS X / MacOS 10.12.6.

Rtl Sdr For Mac Computers

—

Rtl-sdr Macports

SdrDx and SwDb for the PC require an Intel CPU, running Windows XP or (possibly) a later version of the OS. SdrDx requires an RFSPACE, AFEDRI, Andrus MK1.5, FUNcube Dongle SDR, or a Soundcard-based SDR, or pre-recorded RF files (see above for some of these) in order to do anything useful; in the specific cases of the SDR-IQ and SDR-14, you’ll also need a server application that puts the SDR-IQ on the network. SdrDx handles the RFSPACE SDRs and compatibles (and near-compatibles) via the network, it does not directly interface with them via USB. You must run these applications out of the folders they are supplied in, as they depend on files in those folders.

Rtl Sdr For Mac Os

For Windows, I am presently cross-compiling under Windows XP (in a VMWARE VM under OS X / MacOS 10.12.6.)
