There is channel busy detect in almost all ALE hardware, and in PCALE
software. In PCALE it detects both voice and digi sigs.

My understanding is that your group promotes frequency hopping ALE. In
other words, it moves from one frequency to another. The frequency could
be in a given amateur radio band or hop to another band.
The only other kind of frequency hopping I am familiar with is for a

This is my thinking also. I do not think this kind of communications has a

IF PC-ALE good prove that it never transmits when the frequency is in use,
would you have any other objections ? I'm just trying to make sure I

By the way, I have designed a QRL test for PC-ALE. I'll let you know the

It will not do any of that since it has
