Subject: #656: COM1 frequency set to 0 at startup
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=a8d5ac90c6c3ea87d11ca4bdee25e38714add13f;p=flightgear.git

#656: COM1 frequency set to 0 at startup
Also, don't flood the screen with AI ATC messages when COM1/2 is set to 0
(ignore aircraft "transmissions" on frequency "0 MHz").
