> A few days ago, Rick, W2JAZ, asked me if the new, short, weak signal protocol, FT8, could be used on satellites. I posited it might work near AOS or LOS where the Doppler corrections are small. FT8 is operationally similar to the older protocols but four times faster (15-second T/R sequences) and less sensitive by a few dB.

Mine (W5RKN) is a Flex-6500 with two DEMI transverters running SmartSDR, SatPC32, FlexSATPC, and WSJT-X. Rick’s (W2JAZ) is a Flex-5000 with U/V module, running PowerSDR, SatPC32, FlexSATPC, and WSJT-X.

After several transmissions without success, the reply W5RKN W2JAZ FN29 popped up on the screen. Then followed the usual signal report, RRR and 73 transmissions.
