Hi All,
Just received The TurkSat CW beacon and some TX that looks like 9k6 from CubeBug-1.My TNC was set to 1200bd, and I did not have recording on the second RX.
I did record TurkSat and will be posting the MP3 soon.
CW Message as decoded by Wouter Jan PE4WJ: TURKSAT 3U SAT HAAAAAA YM2RTU 0 0 (the last zeroes are ??)

The Recordings can be found at: http://pa3weg.nl/pa3weg/recordings/TurkSat-26-04-2013_0904UTC_1_PA3WEG.mp3 and http://pa3weg.nl/pa3weg/recordings/TurkSat-26-04-2013_0904UTC_2_PA3WEG.mp3
The first half of the pass we were adjusting to the two tone CW. Then we tried if the transponder was on, which was not the case. I cut out this part of the pass.The second half is afterwards.
In the mean time I was trying to RX CubeBug-1, but had the TNC on 1200bd. I did hear some noise increase resembling 9k6 G3RUH FSK.

Hi my friends !
I was preparing to listen the next pass, orbit nr 16160, of Hope-1 HO-68, the beacon of which is on 435.790 MHz when by chance, I came across another CW beacon about 10 kHz higher transmitting numbers at about 25 wpm. The max Doppler shift was at about 0919 UTC from my location in the North of France and the "time if flight" perhaps 15 mn, something like that. I just had time to record the weak (with my poor devices) signal, sound and spectrogram. With the Doppler shift, at 0926 UTC the frequency of this bird beacon crossed the one of Hope-1 producing an beautiful auditive interference and, on the spectrogram, a nice picture.
Any ideas ? As many birds was launched these last days, maybe one of them ?
Best 73 !

Hello J-P,
Most likely you have heard FO-29 CW beacon.

CubeBug-1 Heard on the 12:20UTC pass again.
Hi All,
CubeBug-1 has been heard here again on the 12:20 UTC pass. Its modulation is AFSK 1200bd but seems to be lacking deviation.A recording can be found on http://pa3weg.nl/pa3weg/recordings/CubeBug-1t-26-04-2013_1220UTC_PA3WEG.mp3
The beacon should be on every 30s or 10s. The observed period was 30s.
Possibly, a low deviation FM RX can retrieve the signal.

Last recording for me today: http://www.pa3weg.nl/pa3weg/recordings/CubeBug-1-26-04-2013_1040UTC_PA3WEG.m... On the second orbit I was listening in SSB and captured the AFSK beacon.
Just got the confirmation from the CubeBug-1 team I was the first confirmed RX ;)

Many thanks Scott/N1AIA and Mika/OH8MBN,
Yes, it was FO-29... I wrote 435.910 for the beacon of FO-29 and this wrong frequency was leading me to mistake. The JAS-2/FO-29 beacon is very close to the one of Hope-1.
Thank you again, best 73 !
