[MRCA] 180K-3 18S-4 Antenna tuner

[jeepp]

That tuner is a bit more than a tuner. Its also the low side of the PA tank circuit.  In 1965, Page Airways at DCA still had a mock-up for the 18-S.  I was told that AF and airline techs disliked the radio owing to the laborious procedure to change frequency and tune the unit.  There was a big box of tuning elements that were thrown out.  Wish I had picked them up...Jeep K3HVG

You rarely see one of these, the last one I saw I bought for a friend with an 18S-4 HF transceiver.

It’s a ten preset tuner for the 18S-4 HF transceiver. What’s more impossible to find then the radio and antenna tuner? The mounts.
