FalconSAT-3 is working very well with HTs which are full duplex, or part of a full duplex configuration. AGW, Soundmodem, etc which feed UISS are full duplex, but it is not clear whether UISS is. Guy, ON6MU wasn't sure and thought that two incidences of the program might be needed. Has anybody successfully used UISS with FalconSAT-3? 73s, Alan WA4SCA
