Hi Jeff. It would be a lot cheaper, better, and easier then with your K3 to do full duplex with two cheaper radios. Look at the SDR setups guys are now using on the sats. Get something like an Icom 7200, 7000, 706, or any other HF,2m,70cm multi band and mode radio and use the SDR for RX. This will get you full duplex for less than a good used 910. Checking the AMSAT.org archives would be a good place to start…

There is a built-in all mode Two Meter module for the K3 that you could install (K144XV). For 70CM, the only option for use with a K3 that I’m aware of are transverters. Elecraft offers transverters for various bands (See: http://www.elecraft.com/XV/XV.htm <http://www.elecraft.com/XV/XV.htm>) or look at product offerings from Down East Microwave.

Elecraft doesn’t offer a 1.2 GHz capability but Down East Microwave does. However, until Fox-1C and Fox-1D are launched, there aren’t any L-Band uplink capable amateur satellites currently in service. Fox-1C is manifested to fly on a SpaceX Falcon-9 SSO-A launch from Vandenberg AFB in early 2018 Fox-1D is currently expected to fly on a PSLV launch from the launch complex at Satish Dhawan Space Centre in Sriharikota, India in late 2017. > > Any kind soul, please help me out with an upgrade path of which kits I > need to get to do the full-duplex Satellite work that I used to enjoy. > (I'm all set on the antennas and such, just need the upgrades to the RIG). > Hope this helps, Barry Baines, WD4ASW (Currently in Columbia, SC) > Thanks so much. > 73 > W7BRS ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to k...@arrl.net ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
