What about a second UV-5R? This is a nice radio for its price, so
getting a second one seems like the obvious solution. The only problem
that could happen is that the Baofeng as TX is not so clean or the RX
filters are not very good and you get desense. I think this won't
happen, but I've never tested it. I could test it, because I have a
couple of UV-5R, but probably somebody else already knows.

Of course, the drawback of using a UV-5R as RX is that the receiver is
not so sensible, but I don't think that would be much of a problem to
work SO-50 if you have a decent antenna.

For me, a pair of UV-5R's seems like the best low cost solution to work
FM satellites full-duplex. At 20$ or 30$ on ebay each, the pair can be
cheaper than the full-duplex Chinese handhelds that suffer desense when
working V/U. Has anyone tested if this works as well as it seems?
