Behold, Pete KE9OA signaled from keyed 4-1000A filament:
Hi Gregg,
That is exactly what I plan to use..............I have
been
using that topology for several years now, so I've got the Diplexer
design nailed down pretty well.
You sir, are a god! Do you know how many people that are so-called
"engineering professionals" that do not know how to diplex the output of a
diode DBM?
I'm sold, when can I buy it ;-)
I am not sure why more manufacturers don't use doubly-balanced mixers,
especially when you can purchase a Mini-Circuits ADE-3 mixer for around
3 dollars.
Because they can pay 15 cents for a 2SCxxxx.
It all comes down to money. Nothing is about quality, just mark-up and
useless features.
You seem to be doing something that hasn't been done since the late 1950's
- engineering a soul into the unit :-)
You have my highest respect.

Gregg
