Alan,

Fairly simple, actually.  I just follow the ALE calls around the 
spectrum.  In my case, I primarily use two SDR radios, the RFSpace 
SDR-IQ & the SRL Quicksilver QS1R.  Both allow a visual 
representation of various chunks of the spectrum in real time.  The 
SDR-IQ displays 190 kHz & the QS1R anything up to 30 MHz, but on HF I 
mostly use 250 kHz with it.  Once you copy a specific call on a 
frequency (ALE also looks a certain way on the displays) then you 
either start searching below or above the frequency.  Unless there is 
just one frequency in the net, they have to be moving through their 
net frequencies in one direction or another.  Then it's just a matter 
of following them up or down the spectrum as they sound or call other 
stations.  After a few years of doing this, it sort of becomes second 
nature & you can quickly build a list of  network frequencies for 
specific call signs.

Almost forgot to mention, but for ALE decoding, I use PC-ALE or MultiPSK.
