Brian--

I'm of the mind that by time you buy xtals and/or channel elements, 
etc. you will often pay more for an old Moxy or equivalent than for a 
more contemporary programmable radio.  For example, in our satellite 
receiver system we're using some flea market GE/Ericsson MDX radios 
for both transmitters (with the power turned way back) and 
receivers.  Two radios (one for rx, one for tx), and a cheap 
controller and you have a remote receive station!

And, while it may seem overkill to use a transceiver for just one of 
its functions, when you are able to program all the frequencies you 
might end up using, you gain a great deal of flexibility and 
redundancy in the system.  If the receiver or transmitter of one site 
goes down, you can put in a ready spare and dial in the appropriate 
frequency.

With a lot of commercial users gearing up for a shift to "narrow 
band" (remember when what is now "wide" was considered "narrow"?), 
cheap ($50-$100) Vertex, Kenwood, Standard--even GE and Moto--radios 
are starting to pop up.  Of course, you have to prowl the auctions, 
flea markets and maybe even the dumpsters!
