That's a good link.
Looks interesting. But it also looks like it is pretty
important that the program control the frequency of
the receiver. That won't work for me but I surely
can eavsdrop on one frequency at a time now.

The link also refers to something I've not yet managed to do. The
author says that

"[w]hen the PC-ALE program detects a link being made...the program
will automatically stop scanning and will record the audio on the
channel to a .wav file if the record function is enabled. I have the
recorder set up to record 300 seconds, or five minutes, of audio when
two stations link up."

I have the record function enabled but PC-ALE has never recorded
a .wav file containing audio. I don't know if this is because I'm
never receiving anything to record or because some other software
setting is off. Maybe someone can shed some light on this for me?

From what I have read so far it seems that ALE is used for
monitoring conditions on multiple frequencies and for data
transmission. And that it is used for voice as well as data.
I'm guessing that when the user wants to use a voice channel
it sets up the receiver and transmitter to use the frequency
that the monitoring function showed as having the best propagation
most recently.
So I imagine if you left it running and were listening eventually
you would hear some voice traffic. Then you could see
if the program recorded it.
But I get the impression that there really isn't a whole
lot of real traffic.
If the program was actually making your receiver scan
the different frequencies then I would think there would
be a better probability of you hearing some voice traffic.
Can it actually control your receiver? What kind of
receiver do you have?

I also noticed that PC-ALE is a real CPU hog. It
uses more than 90% of the CPU on my
2 GHz Pentium 4.
