It's not uncommon to hear Brazilian pirates on FLTSAT and UFO military satcom frequencies. I wonder if the recent crackdowns have pushed them to the OSCARS.

well.. when I say students, I meant graduate students at VT that happened to be in the lab when I was doing the experiment. They work with me and Bob, so a few crude words here and there aren't uncommon to them.
But good point, probably not the best thing for a public demo if your audience is a bit younger.
Actually, I've seen so much FM activity (basically every time I've monitored FO-29 since we first came online in late september) that I've been toying with the idea of trying to locate where the source emitters actually are located based on doppler shift data. We know the doppler between the receiving ground station and FO-29, so we can back that out. We know the transponder mapping, so we can work through that to determine what the center frequency is as the signal enters the transponder uplink receiver. What we don't know is the uplink doppler, because we don't know where the emitter is and we don't know what exact center frequency they are on (but I bet you its in 5kHz steps, maybe 2.5kHz). So we have two unknowns. I'm betting there's a way to work through it though, and with enough observations and by watching the rate of change of the doppler, I bet there's a way to make an educated guess on what their center freq and location are.
Or if someone listening knows Spanish and/or Portugese, maybe we could get lucky and hear what cross streets the taxi is going to (if it is in fact a taxi).

Zach You dont need to know the senders exact freq, just a plot of his freq during the pass will form an "S" curve and once you have enough of the "S", you can know his center freq, and hence his closest point of approach. That gives a line of bearing. Anothe pass gives another one, and so on...

Sweet, second cross link signal to look into! I missed that, you got the gears turning.......
So lets see.... 145.900MHz to 146.000MHz for FO-29 passband.
A quick look through JE9PEL satlist reveals these downlinks:
AO73 tlm bcn, 145.935 MHz AO73 transponder, 145.970-145.950 MHz AO85, 145.978 MHz First-MOVE cubesat (NORAD ID 39439), 145.970MHz DUCHIFAT, 145.980 MHz QB50p1/FUNcube3 (EO-79) transponder, 145.970-145.945 MHz VELOX-I, 145.980 MHz UKube-1/FUNcube-2, 145.915 MHz DeorbitSail, 145.975 MHz CAS-3E (XW-2E) transponder, 145.935-145.915 MHz CAS-3F (XW-2F) transponder, 146.000-146.980 MHz Fox-1B, 145.960 MHz Fox-1C, 145.920 MHz
I guess its not that surprising when FO-29 has half of the 2m Satellite Service allocation for its uplink. Next thing to do is figure out which ones are the most likely to be successful based on power levels, modulation schemes, transmission rate, which ones are using Forward Error Correction, etc. And then look at the orbits for possible chain events.
fun stuff!
Does anyone know the uplink receiver sensitivity and antenna gain/design on FO-29?

Hi Zach and group
I think, the main problem is they are not always the same stations. I have heard several different stations in terrestrial QSOs QRMing FO-29; majority of them speaking Spanish and without any kind of ID. I have not heard them recently, though.

That makes sense Hector. I've seen the FM activity kind of all over the transponder. More so than I would expect if it was the same transmitter each time on the same frequency and the different pass geometries causing a bit of swing due to doppler.

Good point Bob. I haven't fully worked through the problem yet, but thats pretty much right in line with what I'm thinking. Thats what I meant by saying watching the 'rate of change of doppler.' When the slope of the doppler s-curve is at a maximum, that should be the point of closest approach.
Actually, that brings up a question. Do you know what type of equation would fit the doppler S-Curve profile? something that could be used to generate a regression equation from a few doppler observations?

Lots of strong FM activity as the pass started and the satellite was over the lower latitudes, but as FO-29 ascended over higher latitudes towards the north pole, the FM activity died down. -Zach, KJ4QLP _______________________________________________ Sent via AMSAT-BB@amsat.org <mailto:AMSAT-BB@amsat.org>.

With regards to FM signals on FO-29, we can also here them here in Australia. This is most noticeable when the Sat is travelling South to North. When it gets above Northern Queensland all we can hear is Indonesian fishing boats on the 2m uplink. It does suck the power from the Sat and usually ends some very good QSO's long before LOS.
