I agree 100% with Mark on all his points. I use LVB tracker with a
G-5400B and switched to the MAX232 chip. I was experiencing very
annoying RFI which I determined was coming from the LVB Tracker.
Changing from USB to MAX232 all but eliminated the RFI. I still
experience some RFI from the computer itself.
I was using HRD Sat Tracker but was experiencing problems with Doppler
correction. When I switched to SatPC, I am right on now. Once I
learned all the nuances of the program, I find it to be the best of all
I have tried and I have tried them all.
BTW, I just experienced my best ever pass of ARISSat-1. I was able to
copy 51 frames of telemetry and Kursk data. It was an 80 degree pass
from the SW. The battery voltage seemed to be up a bit from past
passes. Still no transponder QSOs however. Tried a few times without
success. I wish I had my mast mounted pre-amps up there. Soon
hopefully but probably not in time for ARISSat-1.
