2020-02-20 I think I figured out why I didn't hear satellites with 2 meter downlink 1 year ago
I was preparing for trying some satellite contacts and noticed the Fox-1B and Fox-1D had nicer opportunities for a contact. But I always have problems receiving any signal from those satellites on the handheld radio that I use for satellite contacts, which is the Wouxun KG-UVD1P I got for Christmas in 2012. Not the ideal radio for amateur satellites, but easy to bring along and to program with split frequencies.

A while ago I noticed that radio was constantly receiving noise on the 2 meter band and I had to set the squelch level quite high to stop it. I thought it was some local overload or local noise in the 2 meter band. But today while working on the preparations for some satellite contact possibilities I figured the problem is with the radio and something is actually wrong on the 2 meter receive side.

I have two other handheld radios. One is a Kenwood TH-D7 where I can't change the squelch level so it's not really usable for satellite contacts and the other is a Baofeng UV-5R which can't be programmed via the computer.

So I spent a lot of time entering all the possible doppler-shifted frequencies of both satellites on the keypad of the Baofeng UV-5R. I hope that gives me a working radio for Fox-1B/Fox-1D and I can get a few new contacts in the log.

Update 2020-02-27: I was correct! I tried a Fox-1D pass with the Baofeng UV-5R radio and I had easy reception of the satellite. Trying to get my signal over the satellite didn't work, but at least I know what the reception problem was.
