Bob,
I use the comet CF 416, picked it up at a hamfest for $5.00. I only used it once or twice as the Alinco receiver is not the best on the birds. I now use the Alinco for the L band uplink an d my FT8900R on down link, which rendered the diplexer excess, though I will keep it, since I'll probably find a need for it eventually.

Bob,
I have used a Diamond MX-37 diplexer with an Alinco DJ-G7T for AO-92 L/V. One port to an antenna for 1.2 GHz, and the other port to a 2m antenna. I have done this with a 10-element 1.2 GHz Yagi I ordered from eBay, and the Elk 2m/70cm log periodic I normally use for satellite work. I strap the 1.2 GHz Yagi under the Elk's handle. This makes a two-antenna setup that is a little bulky and heavy, but workable for the 8- to 10-minute AO-92 passes. Some photos can be seen at:

If that link gets mangled, go to http://dropbox.wd9ewk.net/ and go into the "DJ-G7T" folder. Then go into the subfolder with the name starting with 20190303.
The DJ-G7T can work AO-92 L/V full-duplex, but the receiver isn't as good as other radios. Mine is susceptible to intermod if I am near other sources of RF - something that isn't unique to AO-92 L/V. I prefer working AO-92 L/V using two radios, where I only use the DJ-G7T to transmit.
Good luck, and 73!
