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!
