Does the GMSK modem have the same parameters as the D-Star GMSK modulation scheme? If not, how hard would it be to change? It would seem that Satoshi's D-Star adapter could be fairly easily modified to work with these radios, with the control interface using the RS-232 connection. -- Jay Maynard, K5ZC at K6ZC port B http://www.conmicro.com http://www.k6zc.org http://www.tronguy.net http://jmaynard.livejournal.com (Yes, that's me!) http://www.hercules-390.org
