Ted, It sounds like you are hearing a "reflection" of your signal, not the downlink from FO-29. This is a common malady associated with 3rd harmonic interference on mode J (V/U) satellites. Try this on a pass that will reach at least 30 degrees above the horizon: 1. Turn HRD control of your TS2K off 2. Set your uplink at 145.950 CW 3. At AOS you should hear the beacon about 8-10 kHz above the beacon freq of 435.895 (about 435.904 MHz) 4. Tune your receiver to 435.850 plus that same delta from beacon (about 435.859 USB). You should be able to tune your receive and hear your CW dits (clearly). 5. Zero beat the CW dits on the low side, switch to LSB and you should be exactly on frequency and can turn on TRACE and go anywhere in the passband.
If you have auto-Doppler turned on in HRD, your program should do the same thing as this manual procedure. You should be able to hear yourself. If not, Google the diplexer fix for the harmonic problem. >From the center of the passbands, whatever the UHF Doppler shift is, the VHF >Doppler will be approximately 1/3 in the opposite direction. This is a >helpful rule for finding your downlink manually. 73, Jerry, K5OE -- original message -- Good morning, Since putting up the Elk on a rotor (fixed el +- 25 deg), I decided to try some linear birds. I have tried FO 29 about 3x but seem to have some issues. I am using TS-2000 in SAT mode with HRD Sat program. Up: 145.9 LSB Dn: 435.8 USB I am clearly able to track the bird with doppler as I can hear the CW beacon through the entire pass (switching back and forth). I can also TX into the bird and hear my signal coming back duplex. However, what is coming back is my voice signal but totally unintelligible. Also, I have heard no other stations on these passes. Am I doing something wrong? Tnx for any help Ted, K7TRK _______________________________________________ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author.
