[Milsurplus] RBO on USS Pampanito Tour - Crew's Mess

[howard holden]

That panel is not what is on the Ling. There were three sets of four-in-a-row receptacles, end to end above the RAK/RAL and RBS power supplies. Each set of four was attached to one of the antenna connections from the waterproof tube going up into the conning tower. Each receiver had a cable which came out over the top of the receptacles, and you simply plugged a receiver into one of the receptacles.

There were three antennas, and whichever one was connected to the transmitter could not be connected to the patch panels. Knife switches were used to select which antenna went to which panel, and the transmitter had its own, larger knife.

We never actually took the patch panels down, so I have no idea if there were any isolating resistors in there.

FWIW, here is the standard receiver antenna patch panel of the era, with 600 ohm decoupling resistors.
