Tom,

I found a page that show a picture of the SRT-14 Transmitter.

I got to learn how to Tune it Up while aboard Navy Air Craft Carriers,
and I fell in love with the Rig back in 1960-62.

After seeing what it looked like again on a web page (below) I thought
about Your Service aboard Submarines and wondered what LF and HF
Transmitter was used aboard Your U Boat back then? If You Can.

I have heard that Radiomen on Subs got their Broadcasts on VLF instead
of HF because VLF RF Signals could be received while the Sub was
submerged.

I thought that in the 1960's they probably didn't use VLF or LF to
Send their Message Traffic to Sub Command, but used HF frequencies by
rising the Sub just below the surface and raising the HF Antenna above
the Water Line to pass any messages they had to Send.

Knowing the size of the SRT-14 I wouldn't think there would be any room
for one on a Sub. ???

Look at the Size and Discription of the SRT-14, SRT-15 and SRT-16 on the
page I found about them and other Navy Gear at:

Thanks and 73
NNNN

I do not recall the Military designation but it was a Collins
Transmitter.

That is true. Except in energancies we maintained radio silence when
on partol. And receptionof traffic was VLF. The subs used a
floating wire antenna that could be trailed out of the rear of the sail structure. It was retracted when no needed. Transmissions were on HF and
there was a retractable, like Periscope, antenna that was used at
periscope depth.
In my day they experimented with burst transmissions. I am sure in this computer they are a little more hi tech but in my day they used a reel
to reel tape deck. The radioman prepaired the message and put it on the
tape with cue marks for triggering the transmitter. The tape deck was
run at FAST forward speed and sent the message

Hi Tom!

As you posted ...

Bet this will be also fascinating to you! My cousin Bobby Dunkin was an original telecom expert back in even the end of WWII into the 50's. As a kid my Dad forbid us from even having a television set where I grew up in College Station, Texas until one of my uncles, Bill Schuster, who was actually part of the creation of the original Emerson operation and at that time the largest competitor to Allied Radio -forced us- to have a TV set in my parents home here
so Dad could watch Armstrong set foot on the moon! I watched that TV with my Dad and Mother for that episode here in the now Historic House. As fact, that black and white TV set has been donated to the Children's Museum in Bryan, Texas for their exhibition of how TV came to here over uears and years.

As for my first TV view ever, it was up in Erie, Pennsylvania on WICU-TV where Bobby was creating this stuff. My first TV ever seen was actually on a Hallicrafters 7-inch black and white relay rack TV set in my Uncle Bobby's house there during our 'normal' visit to Erie every summer. Leap forward!

Bobby wound up as part of the engineering operation and was involved in the VLF
naval communication design for submarines at sea. He was a part of the design team for the antenna system which was used to punch the VLF signals into the Pacific ocean for I think exactly what you are talking about. He eventually retired from his job up in the Dallas, Texas area long ago. Passed away a number of years ago.
