Crikey. I thought I was way behind the curve with a lot of catching up to do! I've been busy in the last couple of weeks. I built a radio cable using the parallel port to control PTT and I was very pleased when it actually worked. There were three issues I had to deal with: 1) Permissions on the soundmodem0 device. I mentioned how I solved this, but Curt has give the correct answer, which I will have to do. 2) I was using a handheld radio with PTT combined with the mic. signal. I had to put a capacitor in the line from the PC audio out otherwise PTT just pulled the audio signal straight to ground (many PTT circuits don't show this). 3) Tweaking the sound mixer settings to coax the audio driver to work properly. For some reason the mic. input on the laptop doesn't work unless I turn the mic. boost switch on then off again. I knew this was an issue on this laptop as I have the same problem with Skype. After that it Just Worked. Thanks to the XASTIR dev. team for much coolness. 73, Andrew ZL3AME _______________________________________________ Xastir mailing list [email protected] http://lists.xastir.org/cgi-bin/mailman/listinfo/xastir
