I use two Baofengs and an Arrow antenna on those satellites. For SO-50 I have been using the Arrow diplexer as a bandpass filter between the 70 cm antenna and the 70 cm receiver. (Got that tip from someone on this list.) I can't say that it's 100% effective, but it works most of the time to give me duplex.
If you already have the diplexer you may want to try that before you shell out for a new radio.
On the AOs I generally don't have a desense problem with 70 cm transmit and 2 m receive. The radios are Baofeng UV82.

Hello,
I've been working the birds for a while now, and I have been using only 2 Boafengs. I've realized they desense VERY easily on SO-50 and even AO-91 and 92. I have a band pass filter for the FOX sats, so I can hear my downlink. However, I still haven't figured out a way to get full duplex on SO-50. Are there any dual-band handhelds that can receive SO-50?
