I have one of the "rare" DEMI 144/1268 converters; does 15w out. Not many were made/sold before AO-40 crashed. Also a 45 loop-yagi for 1268.
I have a venerable FT736R (with only 2m/70cm) for satellite operation (future). But if the mode will be LV (1268up/145dn) I will have to use a different radio for either uplink or downlink as the FT736R does not do in-band duplex on 144. I have two other radios that will do 2m allmode but it gets more complicated for tuning. FT736R has satellite mode for 2m/70cm (probably one of the first to do that). If the mode will be LU then all is fine.
I also still have my mode-S preamp and two Drake downconverters if ever that band is reactivated.
PS: not QRV on satellites (yet)

Ed, Fox-1D (AO-92) and Fox-1-Cliff will have two different modes U/v and L/v. Switching between two different modes will be by AMSAT command. In addition, AMSAT-UK will be launching their ESEO satellite this year; however, it will be L/v only, per their website. I know of no plans for satellites in the L/u mode at this time. Fox-1D and Fox-1Cliff both utilize and L-band downshifter that uses the UHF antenna, so, by design, these two satellites, will not be capable of L/u mode. Your 1268-144 transverter is certainly rare. I did see where you posted to the AMSAT BB back in 2010 about it, but did not find anything else in a quick Google search. Cherish it. Certainly hope you can get your IF radio sorted out and able to get back on the birds. I look forward to our first QSO. 73, Robert KE4AL On Monday, January 22, 2018, 4:41:06 PM CST, Edward R Cole kl7uw@acsalaska.net wrote:

Hi Ed-I too have a box full of AO-40 (sobsob) S band stuff. Hoping against hope it will be useful. However with so much stuff using 2.4 I think it's not practical for us to be using it. I'm keeping the box, just in case. I would like to see a discussion regarding the use of S band for our satellites. Anyone?

Right now Ham Radio Outlet (www.hamradio.com) has a Yaesu FT736R with the 6 meter module and the 23cm module on their consignment list for $1000
