Hello,



I think the Yaesu FT-980 qualifies as a boat anchor. I didnt know I
wanted one until I did. I was going to get a FT-902DM. while glancing
around Fox Tango I came across the -980. It all lined up. Saw one on ebay,
then found one through a google search. He had it and I bought it. I am a
pretty new ham, less than a year. But not a kid and not new to tech stuff
(aircraft avionics 30 years), but definitely new to this radio and its
operation. I have read that this radio has its...

on the face panel and it came with the original hand mic (which looks
untouched) along with the factory connectors (which are unused as well). I

I have not been able to obtain this standard, and was wondering what others
may use to attain this appearance? I would suspect something like carbon
tet, or tri-chlor would work, but these are now illegal. I...

Youll want to be seated for this one of which I can now say "Ive heard it
all"...



Imagine a boat anchor transmitter that uses a DPST relay to control the
plate supply and oscillator. When the "Plate" switch is turned on, the
relay energizes, the HV supply gets power, and the oscillator cathode is
grounded.



So far, so good...



On one side of the 6VAC relay coil is the Plate switch and that continues
to the 6VAC heater supply hot lead.



Where would you guess the other coil lead would go?...
