[Lowfer] EAR, MLS, TH

[John Andrews]

Mike, Garry,

Back in the day, I spent a lot of time chasing TH and NWNJ. The latter 
was a LOT harder. The best approach was to record WAV files at likely 
successful times of day and night, and then do the detective work later. 
Ultimately, you could use a narrow CW filter and listen to promising 
sections of the file.

I also recall building an 8052-based QRSS keyer for TH, and sending it 
to him. Think it had dipswitches for messages and speeds. Carl was 
pretty well set in his ways, though, so the beacon stayed on CW. As I 
recall, TH had an uh, errr, ahhh... "power change" at sunset. Don't ask, 
don't tell!

I'll have to do some recordings this week, and see if anything can be 
teased out up here. The awful racket down there may ease up when a 
certain neighbor finally goes to bed in the wee hours.

John, W1TAG
