From G3YMC
but the situation as I understand it. It is
rather interesting to note that many of the early operators
on 136 were ex top band
operators. It seems most of these have now returned there.
I thought a lot of the early operators on 73kHz (long before this new
fangled high frequency 137kHz band arrived :-) came from the microwave bands
where a knowledge of how to build your own equipment, to really and properly
understand what you were actually doing, and carry out meaningful
measurements is essential. The topbanders just followed along afterwards.
I've returned to microwaves for now, but if anyone wants to conduct some
serious experimentation into modern low bandwidth signalling techniques, get
in touch privately and we'll take it from there.
