Thanks, Steve, as always.
23CM is enjoyable. I live in the tri-state area, suffolk long island and we have plenty pf 1296 activity. Every Monday, is activity night. Most have long yagi's, minimum 45 element loopers and also amplifiers. Since I moved in January, I dont have up 1296 yet as I need to get my antennas on the roof. Line of sight and height on 1296 is key. I am strictly SSB. Depends on your activity and mode/interest to deteemine the investment. The best I ever worked during a contest was 15 Qso's and like 6 grids.
I too have/had - can't remember if I still do - a SOTA transverter. It drove a solid state amp to about 7 watts that drove a pair of 7289s for around 80 watts out. 125 feet of 7/8 inch heliax to a 45 element looper at 100 feet. About the same setup for 903 and a little less for 2304. But, since I stopped contesting seriously - it's all down. Even with activity night to spur interest - there isn't much. Now the highest I go is 432 with a barefoot FT-847. I give out a few points during contest and that's it. One last comment - if you're going to increase power out, go solid state. It's amazing today what you can get for 1296 for little cash outlay. And yes, if you all a preamp - go tower mount.

Contact Jim, K7ND. He is the Sec of the Pacific Northwest VHF Society. He runs a 1296 SSB net on Sunday mornings. He is on Fox Island. There are quite a few 1296's in the Puget Sound area.

Wow! Cool beans and small world indeed! I "know of Jim" but have never actually met, even though we only live 10 or 15 minutes apart. I'll ping him for some "local input"
Thanks very much, Jim!
Hey - let's get together one day soon - been a LOOONGGGG TIME! Happy to have you over to see my new shack and antenna farm and such.... lunch is on me!
OK Dave. It's been a crazy year, we'll work out something soon. You'll like Jim, he is a good guy.
It was one of only a few options back in the day. I think I bought mine in about 1979 or 1980, something like that. Recall it was made in the U.K. (I think), or maybe Germany. In any case, it worked!
I used 2C39/7289's basically in series, one driving the other. I could swap them around and it worked exactly the same way.
Since "tuning" a tube amp of any kind at the frequency involves tweaking over temperature, always kept a Bird Thruline in the line to keep an eye on output. You could tune up cold, or you could tune up "hot," but they were two different tuning points.
