There were a lot of converted MMDS converted downconverters from the the AO-40 (sobsob) days. I have a couple I dearly cling to, with hopes of a future HEO. There are some commercial ones from Keps, SSB http://www.ssbusa.com/modes.html . and few others. These can be a bit pricey. Try to find a AIDC 3731 downconverter by Transystems. These were converted and sold by K5GNA again back in the AO-40 (sobsob) days. They were an excellent dc and reasonably priced. Once a dc is procured a tv type 18 inch dish with a 5 turn helix feed in front of it makes a super antenna. A simple 8-16 turn helix is another option as well as yagi antennas used for wifi are effective. There a many ways to work this problem. If we had a HEO in the works this bb would be flooded with information, with lots of deals. Good luck with your efforts. Mode S on AO-51 is fun to experiment with.

I'm wanting to try this mode but haven't had much luck finding a
downconverter. What does everyone use? Any leads as to where a
downconverter can be purchased would be much appreciated.
