500kc - Part 7: A Typical Night

This part differs from the previous in that what follows will be
an actual log of signals copied during a typical one hour. During
our training at Coast Guard Radioman School (Petaluma, CA) we
were advised to attempt to log *everything* we heard. Well, that
was an impossible task due to the volume of calls passing over
the seas nightly! (Keep in mind that only short calls were
permitted on 500 - as soon as contact was made one was to quickly
move to a working frequency). What you'll see in the following log
consists of only about 10-25% of the signals transmitted.

   The log consisted of 3 columns: The actual signals copied,
the frequency, and the time. A slash: / was used to indicate a break
between two transmissions, *except* when it was actually sent over the
air to indicate two frequencies - you'll see  ``454/440'' meaning ``you
send on 454 kc and I'll send on 440 kc'' (the -..-. is actually
sent). Ships had a choice of using 425, 454, 468, or 480 kc as
their working frequencies, while shore stations were only assigned one
working freq, usually near one of the above, so in order to
work duplex one of the above, which was closest to the shore's
freq, would be used by a ship.

   Everything you see will be actual transmissions except:
1. When preceeded by OPNOTE (= operator's note)
2. The BEGIN or END SILENT PERIOD entry.
3. The NO SIGS entry (meaning no signals heard in last 5 min.)

Notice the generous use of `dit dit' (and us hams probably
thought *we* invented it!). In the log it is indicated by `EE'.

What you see above is a typical one hour period of evening Pacific
signals transcribed with, again, at most 25% of the transmissions logged.

You noticed the exchanges were short (with operators quickly moving
off 500 kHz to a working frequency) and informal with generous
use of pleasantries such as TU = thank you, TKS = thanks, SU = SEEU =
see you, OM = old man, GE = good evening and of course the ever present
`dit dit'.

Note the prosign VA is the ham's SK.

The 0900 entry was typical for the top of the hour - a dozen
CQ's being sent at once!

The idea of 500 kHz being an international calling *and* distress frequency
was finalized at the 1932 Madrid Radio Conference (see Schroeder 1964).
I find it a shame that amateurs never implemented the idea of a calling
frequency on each band which everyone would monitor, in which short
station-to-station calls and CQs could be made, with parties moving
to another frequency for the QSO. Two-meter repeaters come close to
this idea but operators fail to QSY off the repeater to try to work
simplex.    Oh well - something about Old Dogs, New Tricks...
