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

Has anybody here worked the transponder with a TS-2000?

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,
