Joe,
yes 137555 Hz seems perfectly ok to me. According
to my logs, PA0OCD and others have been operating nearby a couple of times
about two months ago. But all these stations have variable
frequency so it will surely not
be a problem.
If Op-32 were used more heavily for DX work, we
should somehow agree on splitting transmit activity to avoid receiver
desensitizing in the region of the transmitter. For the such digital modes,
using separate preassigned timeslots (eg Europe even / America odd half
hours) would seem simpler and more compatible with software limitations than
organizing split frequency bands. Without much beforehand talking, this has
worked well for WSPR-15 during several nights: Stefan's lighthouse beacon sent
50% duty cycle on even 15-minute slots, we Eu's simply went along and
joined him, and soon afterwards the Americans could be found using
those other slots.
Best 73,

Graham,
Thank-you for all the info. It will
come in handy when I start
using Op again. Unfortunately, there were
some stability issues
last night which should be resolved soon. When
that's done and
a pc keyer is made for the new exciter, we should be back
to
the opera. Based on the info from Markus, perhaps 137.555
would
be a good place to start.
thanks again!
