Anyone know the PRECISE dates (not "first weekend in Oct.")and times
designated for the Calif QSO Party this year?
Thanks, Larry N6AZE

'Course the ARRL Handbook says: "...S meters are relative-reading
instruments..." and: "No two receivers render the same reading of a given
signal, unless by coincidence. This is because the gain distribution within
the amateur receiver varies from band to band. Since most S meters are
activated from the AGC line in a receiver, what might be S9 on one ham band
could easily become S6 or 10 dB over S9 on another band. A receiver that
rendered accurate readings on each band it covered would be extremely
esoteric and complex. An attempt was made by at least one manufacturer in
the early 1940s to establish some significant numbers for S meters. S9 was
to be equivalent to 50 microvolts, and each S unit would have been equal to
6 dB. The system never took hold in the manufacturing world, probably for
the reasons given earlier." They are useful for comparison, say between
"high" and "low" power during a QSO, but the actual S meter readings are
relative.

Great time, part time effort this year. Both operators burnt out by late
evening. Also had much fun on 10m, hopefully got some new contest
operators from there! Look forward to next year!

Is there anyone who has tried the KLM Log 7-30 8 Ele log periodic
antenna? Wonder how it compares gain wise over similar size antennas?
Would like some feedback as a frined of mine is planning to put one
up about 110 feet on Rohn 45.
