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 interested.
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. http://www.ssbusa.com/ordering.html
