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

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

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

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

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

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 It was retracted when no needed.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

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

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

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