Millen 90800 transmitter
#1

I sometimes just get these items because the alternative is the dump.

I’ve gotten a Millen90800 50 watt exciter circa 1940. I guess it will make a nice CW transmitter for SKN I guess. Anyone know anything about this? I have a copy of the manual and the 1940 QST article so that may be it.

Hope these links help looks like a fun project. David   https://www.jamesmillensociety.org/eqpicts/90800.html    https://www.radiomuseum.org/r/millen_50_..._90800.htm  https://www.qsl.net/la5ki/org/mi/90800.html

I have a hb copy of one from the QST article. Don't know when it was built maybe in the '50s or '60s. The coils are kinda hard to come across.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
