Thanks for confirming this, Andy,
When I monitor the ALE frequencies, particularly the 14109.5 frequency,
I do hear a fair amount of ALE throughout the day, and sometimes other
modes. I admit that the stations that I am hearing are the same ones
over and over and over. Generally speaking
Have other ALE users found that they could not transmit on a busy
frequency when using PC-ALE?
(Note: there are no channels on HF amateur radio frequencies except on
60 meters which prohibits ALE and digital operation of any kind).
Perhaps I have things set up wrong, but I did a basic test of
I have found that I could NOT transmit once. This was during the presence
of a strong broadcast band station in the 40M band. I then tested by
sounding on top of WWV, a strong SSb signal and a strong AM signal, each
time PC-ALE attempted to transmit. Thus , I conclude that I need to be
present

As Bonnie mentioned last week, ALE has no busy detect for
none ALE signals. So yes, Soundings and certain other
aspects of ALE cause QRM.
Hi Andy,
A few weeks ago, during the discussion about busy detectors, I
described some of the different busy detect systems that are
Automatic channel busy detection has been standard in ALE transceivers
for many years. These are transceivers that have ALE embedded in the
microprocessor inside the radio, and they don't need an external
computer.
As an example, my Icom IC-F7000 HF ALE transceiver has a very good
busy detector
