HS0/WQ5W

[Alan Benoit]

I will be leaving for Asia on Saturday.   My travels will take me to Bangkok
on March 12 where I plan on operating as HS0/WQ5W from the club station
there-CW is my preferred mode.   I will be back in Bangkok the weekend of
March 24-26 and plan on operating as part of the M/S team in the CQWPX SSB
contest.  I haven't heard what the call will be yet.

Tactics similar to these are used in SSB contests. Generally employed
by Multi-Tower, Muti-Beam, Mult-Operator and High Powered stations. They
increase the processor level to were there is considerable flat-topping
of the audio signal and the coresponding wide transmitted signal. They can
effectively clear a swath of frequency 5-8 kHz wide and make everyone
within 15 kHz wish they had something else to do that weekend.

The technique you mention is very interesting. I'll have to keep it
in mind for the frequency wars in November.

However...if you confuse just ONE guy by excessively abbreviating numbers,
and he asks for repeats, it will waste the "saved time" for AT LEAST 50
QSOs, destroys the pileup rhythm, and gets the DX op's mind out of the
groove.  Figure that the confusee's call will probably be a 2-by-3, will
be sent slower, and may take more than one repeat by the DX op to get it
all straightened out.

Penny-wise and pound-foolish to trade those four dots against the probable
disruption, in my opinion.  Better to keep order and keep everyone
informed and on the beam.
