DigiFAQ Updated: An HF Digital Decoding primer and reference tool

Many thanks to SWLing Post contributor, Mike Agner, who writes:

[S]ome 20 years ago, Mike Chace-Ortiz, Stan Skalsky, myself and a bunch of other folks put together a FAQ about digital modes on radio – specifically modes going from LW way up into the UHF spectrum- called the DigiFAQ 5.3. I was responsible for the HF Software section, and as you might know, back then it was all about the hardware. InfoTech was still around, and amateur digital modes using the PK232 were plentiful. There is a PDF-based copy on the UDXF website [click here to download].

Now jump ahead 20 years or so, and things have changed considerably. Hardware is no longer king, and soundcard-driven software has taken over the market. Even receivers have changed – the desktops of old (quite apart from the current batch of ham transceivers that have general coverage radios built in) have been pretty much supplanted by Software Defined Radios. Along with that, the digital modes themselves have changed drastically with some disappearing altogether, with new ones like ALE going to the head of the pack. Too, the original DigiFAQ combined many ham-related modes along with everything else.

[O]ur original work didn’t really address some of the basic questions newcomers to this side of the hobby might have, [s]o with Mike Chace-Ortiz’s help, I have been involved in rewriting and updating the FAQ. Its approach is different – we start from topics like discussing radios, SDRs, some of the terminology you will see on mailing lists like the UDXF and much more. Only after we cover all of this do we discuss decoders – and even here, this topic is broken down even further, to include those decoders that play nice with some SDRs, and some of the tools you can use to help analyze an unknown signal.

Then we go into the modes (most are HF related, but we do touch on one or two common LW modes). We identify those modes that are dead, and separate them from the rarely used/active ones. Where possible we also supply waterfalls for each.

We also have an extensive appendix with a whole bunch of links for additional reading.

Perhaps of greatest use to newcomers is a listing of known scheduled broadcasts, so they can test what they download without wandering all over the place, hoping to find a readable signal – and potentially getting turned off when the don’t find one. We have also recovered a few articles from the old WUN archives as well as from SPEEDX (Society to Preserve the Engrossing Enjoyment of DXing – folded a long time ago) on certain digital related topics, such as discussing how to read an AMVER transmission.

It should be noted that we also sent the amateur radio digital modes to their own page for a very simple reason – while these modes are well understood (and many have their own devoted page that cover their mode far better than we can), the single biggest reason was that these modes can NEVER be encrypted (at least in the US, and likely other countries as well). Sad to say, but there are many modes outside of the amateur bands that we will never be able to read, and some whose purpose is unclear. As of this writing, many UDXF members are noting signals thought to be Russian in origin, utilizing a variation of MFSK-16, a mode generally associated with amateur radio.

Is this document complete? Not even close. It’s designed to be something of an introduction, with enough detail to hopefully draw in both the newcomer and experienced. There are new modes being identified, new networks, and even new players being found all the time. There’s still more work to be done on this, and this is yet another change to the original DigiFAQ- it’s hosted on the RadioReference wiki, where any member (with a free ID) can edit and add to it.

Regards, Mike

Thank you for sharing this update, Mike!

I receive a lot of questions regarding digital modes even though it’s an area of the hobby where I’m quite weak. I’m pleased that you, Mike, Stan and your team are all working to keep a reference source up-to-date for folks exploring this dynamic part of the radio hobby.

December 15 and 16: Amelia Earhart research broadcast

Amelia Earhart’s Lockheed Electra 10E. During its modification, the aircraft had most of the cabin windows blanked out and had specially fitted fuselage fuel tanks. (Source: Wikipedia)

I’ve been sent this message from a number of sources. I hope it’s true as it’s a fascinating concept:

Hi, my name is Les Kinney and I am a retired federal agent and historical researcher. I am part of a group that will be traveling to a remote atoll in the Marshall Islands in mid-December. Our research concerns the theory that Amelia Earhart ran out of gas and landed wheels down next to a small island at Mili Atoll. There were three local natives who witnessed this landing during the late morning of July 3, 1937. We have found aircraft artifacts on this small island which we believe may have come from Earhart’s Lockheed 10E.

We also believe Earhart broadcast distress messages that were heard for the next several days. These voice transmissions were heard by the U.S. Coast Guard, Navy, three Pan Am listening stations and several radio listeners in the United States, Canada, Nauru, and Australia.

Unfortunately, because of atmospheric conditions, most likely caused by thunder storms, most of the messages were garbled and unreadable. Several radio listeners believed they heard Earhart speaking. Most heard a word or two; some a sentence or more. Some thought they heard partial latitude and longitude coordinates. None heard Earhart report she was at a specific geographic location except one. That person was Nina Paxton, a registered nurse from Ashland Kentucky. Nina had a new Philco console radio and said she heard Earhart around 2 pm Eastern Standard Time on Saturday July 3rd, 1937. Nina reported Earhart saying they were down on a little island at Mili Atoll. Amelia mentioned her navigator, Fred Noonan, was hurt, they were almost out of gas and warned they couldn’t stay there long.

Earhart’s Lockheed Electra was equipped with a 50 watt Western Electric model 13C transmitter. Earhart would have had to have one engine running to transmit. For a variety of technical reasons, she would have likely been transmitting on 6210 kilocycles high on the AM band which was her day time frequency. There is a remote chance she was broadcasting on 3105 kilocycles her night time radio frequency.

We would like everyone’s help. We are going to attempt to duplicate that 1937 transmission from this remote island. We will use Earhart’s identifying call sign of KHAQQ to begin the broadcast. We will broadcast twice: at 12:30 pm or 1230 hours Eastern Standard Time (EST) and again at 1:00 pm EST or 1300 hours on two successive days, December 15, and 16th, 2016. The first broadcast will be on 6210 kilocycles and will last for one minute. We will repeat the message twice, two minutes apart. After the third transmission on 6210 kilocycles, there will be a three minute pause and we will then broadcast the same message on 3105 kilocycles for one minute, three times, with a two minute delay after each message.

We know this is a long shot. We can’t duplicate the atmospheric conditions from July 1937 and there is so much more RF interference in 2016. But it is worth a try. We are asking everyone having a receiver capable of listening to this broadcast to tune in on these frequencies.

Whether you have an old 1930’s radio, or a modern radio with short wave capabilities, keep your cell phone cameras and video cameras ready to capture the moment. Flash the camera on your set and then to yourself while you record our broadcast. If you’re lucky enough to pick up the transmission, you will likely get five seconds of fame on a future TV documentary.

If you do receive our Earhart recreated broadcast and capture the message on your cell phone camera or camcorder, call us on site in the Marshall Islands via satellite phone. That number is: 011-881-651-463- 951.

Please pass this message on to any other radio groups, forums, or interested friends. Schedule: December 15, and 16, 2016 6210 Kilocycles: 12:30 pm – 12:32 pm – 12:34 pm (All times EST) +5 for GMT 3105 Kilocycles: 12:37 pm – 12:39 pm – 12:41 pm 6210 Kilocycles: 1:00 pm – 1:02 pm – 1:04 pm 3105 Kilocycles: 1:07 pm – 1:09 pm – 1:11 pm Les Kinney


December 15th and 16th, 2016, callsign KHAQQ

  • 6210 kHz: 1730 UTC (12:30 pm – 12:32 pm – 12:34 pm EST)
  • 3105 kHz: 1737 UTC (12:37 pm – 12:39 pm – 12:41 pm EST)
  • 6210 kHz: 1800 UTC (1:00 pm – 1:02 pm – 1:04 pm EST)
  • 3105 kHz: 1808 UTC (1:07 pm – 1:09 pm – 1:11 pm EST)

There is little hope this broadcast could be heard in eastern North America (based on time of day and frequencies), but I imagine it could be received in Oceana and Asia.

I’ve written Les Kinney asking for more information. I’m specifically interested if his team has gotten special permission to use this callsign. This is a fascinating way to test the theory.

Please comment if you manage to receive this broadcast or if you have any further information!
