After the contact, I switched over to ALE 141A and listened for quite
some time in unproto mode. Later on I heard an eastern station calling
the HFN, which must be the HFLink Network. This can not be an automatic
station as it was outside the automatic subband. I am not suggesting
that it was
PC-ALE , and I assume Multipsk ALE, is designed to work in attended mode for
almost all applications other than two likely scenarios.
1. Soundings: This now referred to as station ID by the HFLINK web site
(http://hflink.net/qso/). I think this is a fair description, since it
simply sends the
Andy has some very good points,
If you are a human operator and listen on the frequency for a period of
time, ideally at least a few minutes if you do not use QRL or a voice
equivalent, and do not hear any other activity, you may be fairly safe
in assuming the frequency is not in use. It is

It is truly amazing to me that the same hams who have torn up this group time
after time, objecting long and vigorously against
automatic Pactor stations , are promoting the concept of ALE sounding on HF
24/7
Talk about being hypocritical !!! If we have 1000 Ale stations sounding 24/7,
how

anywhere will make a contact! :-)
That said, in small numbers the ALE sounding-QRM is

Were the usage numbers to increase then the sounding-QRM
could definitely become more than an occasional nuisance.
Since ALE is
