The one in the link (above) is an old AN/FRT-40 used by the Navy primarily
at shore based naval transmitter sites from late 40's. They were phased out
by the mid 70's.

The "40" was a 50kw version of this, an An/FRT-39. It was used both at
shore stations and aboard ship.

The left side rack contained the modulation mode select (CW, FSK, Voice, and
the output mode .... carrier or SSB. It had an "exciter" capable of 1000
watts used to drive the right hand side, 10kw power amp. The exciter could
also be used by itself, hooked to an antenna in emergencies. We used to
have a lot of fun screwing around with that.

A FRT-40 added an additional power output section to raise the output to
50KW

I can't remember anymore. Is it "peak the grid, dip the plate" or the other
way around?

Yeppers - never owned one, but one of my buddies did.

This was my very first shortwave radio I built in kit form.

http://oak.cats.ohiou.edu/~postr/bapix/Hal_S119.htm

I remember when I built it, the detector diode was blown so my Dad and
I went to Radio Shack in Boston and got several. There must have been
a difference, because that radio was HOT even on the built in whip
antenna.

I outgrew that one and managed to save enough money to get the SW-500.

http://oak.cats.ohiou.edu/~postr/bapix/S120.html

By that time, I had my ticket and was using it as a standby receiver.
I still have it (had it recently restored) - modified to receive SSB.

Man, those were the days. Staying up late at night "working" AM
stations around the country. In those days, the SWL could write the
station, send a signal report with a brief description of the
programming and how long you listened and the station's Chief Engineer
would return a QSL card verifying that your information was correct
and a thanks for listening.

My very first one was a station in Des Moines, Iowa - a small, 1kw
(night time) country western station. I'd have to go through the QSL
card file to remember the call sign. One of my best shortwave ones
ever was Thailand - AM no less on a rainy Saturday. Took five weeks,
but I got the QSL card. :)

Here's one I used at the Marine MARS station on Okinawa fro RTTY traffic..

http://www.collinsradio.org/html/kw-1.html


We also had several Collins original *S* Line setups. We had a 600' per leg
rhombic pointed at Southern California, Camp Pendleton. They were are main
outlet for RTTY traffic.

BTW, don't peak the plate, you'll be replacing finals. 8)

My Dad was a ham from the 1930's. Never got active again after the forced
shut down during WWII. In the 50's when I was 12 he bought me a kit from
Allied Radio. Looked about the same as your Sky Buddy except had plug in
coils for various frequency ranges.

That got my Dad started again and I progressed up the ranks from novice,
general and amateur extra. I haven't been active for many years. Except of
the CW banks it seemed that the rest of the frequency allocations turned
into a giant CB party.

Ahhh, the good ole days....

You got it right. " Peak the grid, dip the plate, keep the fire in the
wire". :)

Being a moron, I used to mix that up all the time. Had a few thermal
runaways in the finals which my Dad was never too pleased about. :)

Got to play with the exciter of one once when I worked some MARS phone
patches back in the day. I couldn't talk the Chief into letting me
fire up the finals on the big guns though. :)

I did get to play with an Air Force station at full power once though
- blasted a signal right below the lower end of the 20 meter ham band
on a phone patch to the East Coast - MARS again.

That was cool. :)

Man, we could get away with some stuff back then on MARS.
