ARISSat-1 transponder question
Happy New Year!
This morning I kicked off the new year with 2 passes of ARISSat-1, copied both CW beacon, BPSK telemetry and FM voice/SSTV simultaneously on Kenwood TS-2000. I would also like to try the transponder but don't know if my transceiver allow it? This TS-2000 has all modes on its main transceiver but its sub receiver only supports AM or FM. Could anybody help?
Thanks, Thu XV9AA
Hi Thu,
Happy New Year to you as well!
I don't have a TS-2000 myself, but that rig should be fully capable of working the ARISSat-1 transponder, many hams use the rig for AO-07 and VO-52 which work essentially the same way as ARISSat.
The challenges (above copying the downlinks as you're doing now) are that you'll need to have the uplink (70cm) antenna working, as well as have the computer control of doppler for up/down on your rig. SatPC32 works well for this. Also, signals through the transponder are very weak, so you'll need to have some gain in the antennas and/or power on the uplink.
On a related note, I had a nice (short!) QSO with N6EV tonight through the transponder -- 01/01/2012 0124z. It's super-exciting to hear another station coming through the passband!!! ARISSat-1 may not have much time left, but it's still working great.
73 and Happy New Year all,

Hello Dave, Thank you for your response. As far as I know to use the transponder I have to use LSB for 70cm uplink and USB for 2m downlink? However I can only set the TS-2000's main transceiver to LSB or USB while its sub-receiver only supports AM and FM. Power is not an issue for me and I have Az/El controlled yagis.
Has anybody here worked the transponder with a TS-2000?
73, Thu

Hello Thu,
YES, the TS-2000 will work linear transponders. You need to put the radio into "Satellite mode" and it will do any mode in both the main and sub bands.
The difference between satellite mode and just using the "sub receiver" is that in satellite mode, the main side of the radio is receive only, and the sub is the transmitter only (no receiver function).
So, check out the purple satellite mode button :)

Hello Mark, Thanks for your suggestion, I have looked at the manual to learn about this function. Tomorrow morning there's a good ARISSat-1 pass over my QTH and I'll give it a try :)
73! Thu
