Re: Resurecting Pulse ...

I once, several decades ago, had a job designing RF diathermy
equipment, and I was amazed at the ease with which it was possible
to generate several hundred watts of 2.45GHz using a cheap
magnetron. Locking of 'maggies' has been a topic of speculation
for as long as I've been interested microwaves. At that time the
PSUs were crude, although I was able to set that company on their
path to the use of switchers before I moved-on.
I understand that the 6kW device used by the Bochum group to receive Venusian echoes was a phase locked, as opposed to injection locked, magnetron; it would be interesting to research that one day ... However, with the exception of 2.4GHz it seems likely that the sticking point would be locating a suitable tube tuned to an amateur frequency, unless, of course, somebody wishes to try making one!
