[AMPS] QRN

The noise on the AMPS@CONTESTING list has gotten so high that I need 
to QRP for awhile. Overnight I got seven digests with contents like 
this:

I work on RF power systems for a living, so I don't find reading 
endless debates on 'theories' of arcs and parasites as continually 
stimulating or even fun. I have to work 9 hours a day, and spending 
10 percent trying to read through the point/counterpoint debate here 
is not productive for me or my employer.

I always hope that some new topics about amplifiers will arise and 
teach me something; for the past 3 years it always seems to drop back 
to the same subject. New topics such as class E amplifiers, use of 
connectors, tube sockets, types and performance of tubes, switchmode 
power converters, automatic tuners, solid state designs, etc. have 
been really interesting for me. Continuing to smash our heads over 
whose theory of parasite/tube damage is correct is consuming too much 
time. I apologize for reviving that article about the old WLW 
transmitter design a few years ago. It seems to be held in high 
esteem but practice has improved since then.

I have had my share of parasite chasing, and usually am successful in 
squelching them. But I don't continually press everyone with my 
issues like a "Born Again" religious fanatic. Please accept my 
apologies if I step on any toes here.

I'd like to use a filter to trap out certain messages, but since I 
get the list as a digest, to minimize constant email interruptions 
through the work day, I don't see it possible. Any help here would be 
appreciated, I am using Eudora Pro 4.02 emailer.

Meanwhile, the trashcan is quickly being filled with digests such as 
above. If anyone wants to reach me, send email direct. Thanks, all.
