I agree with your assessment. Using SDR on satellites is a wonderful
thing. I have been assessing the value of SDR on satellites for
several months and my personal conclusion is that it's benefits far
outweigh the negatives. I'll be writing up my notes for a short
I'm quite spoiled using my FUNcube Dongle Pro+ to receive. It does a
great job, allowing me to see the entire passband of all our current
satellite fleet. Not only can I visually see the passband, I am
recording it in both AF+RF so that I can go back and look for things I
might have missed during a previous satellite pass.
My biggest complaint about using the SDR setup is having to switch
cables depending on by transmit band. I'm looking for clean solutions
to switch between U/V and V/U configurations, giving me the best
isolation and protection for my SDR devices from the transmitter.
Some folks don't like the short delay effect using SDR. I find it is
manageable and can be "tweaked" for optimum performance.
