[Lowfer] Modes, signaling, and data recovery

[John Andrews]

Les,

There was a fairly definitive discussion of QRSS/Jason on the RSGB
reflector, as I recall. Unfortunately, the message must be on my computer at
home. I'll see if I can find it tonight.

I believe the conclusion was that Jason would be similar to QRSS10 or so in
terms of getting clear copy. Based on the experience that Dex and I have had
with reception reports, I think that's pretty close to the mark. I certainly
believe that WOLF works much better into the noise. For example, Dex never
successfully copied my Jason signal, where he had almost instant results
with WOLF. Based on a test at home on Tuesday night, I'd say that WOLF could
provide at least one line of clear copy from a 27:12 minute recording at a
signal level that would be "just" usable for QRSS60.

While Dex and I are planning a WOLF QSO for this weekend (time not
determined yet), a Jason QSO would be a far simpler and quicker thing, as
the EU guys have demonstrated. So, I think Jason has a real place in our
arsenal, but not for the very weak signal work.
