[RTTY] Fw: ARLB006 NTIA: No Objection to Additional Data Modes on60 Meters

[Jeff Blaine]

Joe,

Got it.  While I don't have as great of a mind as you do, we are thinking 
the same.

FSK is the best mode for technological novices.  Part of it's attraction is 
that it's use is simple and without any pesky levels to adjust.  It's pretty 
hard to screw up an FSK implementation.  On the other hand, AFSK really 
should only be used guys with a sufficient tech background to  know how to 
do it properly.  AFSK in the hands of rookies frequently involves the 
problems exactly as you have explained - as is often lamented by the PSK 
crowd (for the same reasons).

Got to leave Koh Chen's message for tomorrow.  I can't consider any message 
of his without a couple of cups of coffee first.

No, what I mean is AFSK with individuals who don't know what they're
doing is just plain crap and there are far too many individuals who
either don't know what they're doing or don't care what they're doing.

Couple that with AFC that causes then to walk all over the band and
AFSK is as big a disaster as those g'auwful PACTOR automated QRM
generators.

FSK is bog simple and nearly impossible to screw up in such a way as
to make a mess of the signal.  Those who don't know what they're doing
may end up with nothing but a carrier but they don't have 3 KHz or more
of hum modulated harmonics.

73,

    ... Joe, W4TV
