Hi Robert,

I use an SSB Electronics UTM 1200dlx converter, that I originally
purchased for AO-51.  I believe that it is no longer in production but
there may be used units out there.

5W in, 15W out, powered via a power injector in the coax line.  It's
weatherproof and I used it outside several years before I moved the
antennas "inside".

An FT-817 is a perfect IF radio although I'm sure there are others you
could use.  The UTM was designed for 1268-1270 MHz with 144-146 MHz
input, so in order to get on AO-92 you need to account for that.  I have
the older FT-817 not-ND so it's just a menu setting to open it up.  I
switched to my FT-857 for AO-92 though because I think my 817 finals
gave up the ghost just in time for launch.    :-D
The FT-857 mod to allow the 143 MHz operation was easy for me, if anyone
is interested, and that says a lot since I'm not someone who you want to
try soldering anything under 1/8 W resistor size or so. 

It has done a great job for me on both AO-51 and so far, AO-92.  It has
been turn it on, operate, forget that it's there.  I don't have any
power measuring equipment for 1.2 GHz but I believe from the AO-51 use
feeding through a lot of coax and watching on my SDR now, even down to
1/2 W in produces 1.2 GHz power out.  Found that out when the 817 power
went low but I switched to the 857 just to be sure I had full output for
testing and commissioning AO-92.

Maybe eBay or a hamfest might turn something up for anyone who is

I didn't find much on an internet search when I was looking for a manual
the other day, the only hint I found was an (old?) SSBUSA price list.
