Just now on FO-29, I observed and recorded part of some strong FM QRM. These signals corresponded to an uplink of 145.900, and were from at least two sources, as there was a Spanish language QSO (of which I caught one US callsign), and a possibly non-amateur QSO in English with a northeastern accent and foul language. One or more of these may be originating from an Echolink node or similar gateway outside of the identifying station's control. I want to put this recording out there for anyone who might know or recognize the stations, and anyone that may hear something I didn't. The recording ends at about 16:08:15Z today.

Hope this helps, BTW I am an old SIGINTer, both Voice, non-Morse, and Morse Interception. FWIW, this was pretty rough copy for FM. I used an audio processing system on my Linux workstation called "Sox" with various plug-ins. Not like the olden days with an R-390 or the CEI-2000 listening to Soviet Cosmonauts.

I'm thinking we had an authentic FO-29 QSO and could only hear one side due to footprint. The good ole boys most likely were terrestrial running lots of power and in what they figured was unused space. We had similar problems in Germany with East German truckers using imported FM radios.

Dave, You might want to check that again. A Google search by the KM4MD does come up with a woman, but the qrzcq.com listing you linked has a name of Bill in Georga, and the FCC ULS does not list a license (any status) for KM4MD. The Twitter / Instagram accounts pretty well explains her handles and it has nothing to do with amateur radio. It's her name - Kathkleen Matthews 4 Maryland (where she lives).

I imported the mp3 file, used filters to zero out anything below 1000hz and above 5000hz, then reduced db gain of 3000 hz center. Copied the results, then re-ran the processed audio with 20db gain. Headphones. I might try running original through my SDR and tinker with outputs.

No I didn't, just pure audio filtering. Everything above 5000hz was very distorted by noise. Everything below about 850hz was also distorted by phase noise. I just did a quick and dirty for the voices. The US guy was pretty clear around 1500 hz, high pitched voice.
I didn't hear a side tone, but probably missed it.
I would guess that the US guys were using what they figured was a clear channel and running high power with a directional antenna. Most likely a good ole boys' intercom. Some of the good ole boys' around here run a couple hundred watts, a horizontal yagi, and SSB. Your guess as good as mine. Not enough other data for me to call in an air strike.
The Spanish language might well have been a legitimate FO-29 QSO, we just heard one side of it. Wonder what the orbit foot print looked like at that specific time?

Sounds like the northeaster is using a 229.1 Hz tone, if that might help in guessing a repeater.

Interesting. By the pace of the conversations, the SSB guys don't sound like they know they only have a few minutes to wrap up the QSO. Bad language etc. aside, they might be using simplex on that frequency and probably don't realize they transmitting on a satellite uplink frequency. Just a theory...

I re-listened to the audio. Indeed, the call was KD4MDF. His accent was definitely central American Spanish. Most likely a Hispanic-American; the way he used the phrase "y yo lo creo" is a colloquial Spanish expression used by many Mexican-Americans. Literally translated it means "ok, I got that". It really means " .. and, yes, that is it ..." If he were European Spanish (the Mother-tongue) he would have said " Y Ya lo creo". There are so many distinct accents and little catch phrases in Spanish it it just like English. When I was in Spain, locals would immediately identify me as having learned Spanish from a Mexican. FYI my mother was raised by a Mexican Nanny who was Poncho Villa's youngest sister. I have lots of QSOs in Spanish as well as having done voice intercept operations for years, so I am sort of attuned, as it were. Never have a problem on CW, however :-). BTW, if you listen to the drug traffickers on 40 meters, you will hear that they have "zapatas" (shoes) --- those are kilos of heroin. Enough of this off-topic stuff already!

Actually, the accent is from the Dominican Republic. In the recording we hear two callsigns, HI3EAS and KM4MDF. I'll be glad to shot him an email. Just let me know which frequency were they using.

The FCC site said "no match for KD4MDF"
This is an interesting topic, and I know there has been a thread or two on it in the past. FO-29 is a unique bird in that the uplink passband fully covers about half of the allocated satellite band at 2m.
I currently have a project (albeit shelved at the moment, but we do have a code base built up) going here at VT that is looking to geolocate these types of interferers by taking doppler measurements, specifically looking at FO-29. Right now I'm exploring this as part of a potential class project as it teaches the basics of orbits, doppler shift, and how to simulate these types of things in software. It is actually pretty similar to the AO-73 to FO-29 crosslink project we did for the SatCom class, with the signal source being an illegal transmitter on the Earth instead of another amateur bird.
In my initial research/experiments with this we have heard both Spanish and English (about a 50/50 split), and I know there have been previous reports of Portugese (Brazil). Most of the time the signals tended to show up in the lower portion of the downlink passband during our experiments if I recall correctly. Some of those recordings too were with South/Central America completely out of the footprint on ascending passes. And I remember from previous threads folks mentioning this type of thing over Europe as well (I think there is even a Youtube video or a blog out there somewhere). So I would say that calling this problem 'prolific' is reasonable, and that no one country is at fault.
My question for the group is this: Would a database of these interference events be something worth taking to say the IARU? If we keep this project going and a few other things we are working on come together, it is my longer term goal is to take frequent recordings of these events and build up a database with records of who was transmitting, what language, what frequency, what mode, and what country (maybe even city?) they were transmitting from. After we build up a good data set, we could then go to the legal bodies in those countries (or the IARU?) and hopefully have them lean on the illegal ops to cease transmission or at least change frequency out of the satellite bands.
I won't hold my breath about the various bureaucracies of the world actually taking action against the illegal transmitters, but it couldn't hurt to try right? And it would be good to at least document the prolific nature of the problem. For the mean time though, its an interesting phenomenon and makes for a potentially good class project.
-Zach, KJ4QLP
P.S. I'm having visions of a fleet of Amateur Radio SIGINT birds monitoring our spectrum. A 200 kHz receiver for the 2m band, a 3 MHz receiver for the UHF band, combined together and downlinked in say S-band where there's more room to play. Kind of like how the COSPAS-SARSAT payloads on the NOAA birds are looking for emergency beacons at 406 MHz and bent piping the signals down in L-Band. Probably not feasible...but it would be cool and useful for policing our spectrum, and would help defend the S-Band spectrum for hams.
