So your idea of "good intentions, tolerance, and friendship" is "The automatic band segments are a stupid place to park a slow keyboarding digi mode... like they say, If you can't stand the heat, stay out of the kitchen. :)"
Do you have a receipt for those frequencies you seem to think you own? 73, Dave, AA6YQ --- In digitalradio@yahoogroups.com, "expeditionradio" <[EMAIL PROTECTED]> wrote: > > > Andy K3UK wrote: > > However, what is the REAL difference between sending > > your callsign a few times via ALE , versus picking up > > the Mic and asking "is this frequency in use" ? > > Hi Andy, > > I agree Andy, a normal ALE sounding or linking burst is only 10 to 20 > seconds duration, and consists of simply callsign ID.
