Mitch, my radio looks like yours except I don't have the knob on the far left. That's where my Raytheon emblem is placed. You have a B.F.O. circuit (C.W. Radio, switch) in your radio to make tuning Morse code on band 'A' and perhaps band 'C' easier on the ear. The radio was used on small pleasure craft in the 1950's and 60's for sure. If the boater had charts they would show the positions of AM and Beacon transmitters, say around the Great Lakes and be able to use the large rotating antenna on the top of the radio to find there location on the chart. Now sailors have GPS type equipment that automatically tracks their position. My radio needs some work. Does yours operation on all bands? the Radioskip 1

Hello,

I never found a schematic for the radio. When i got mine it did noting at all.

I changed the filter capacitors, tested the tubes and found two bad. I changed all of the wax/paper capacitors.

Measured all of the resistors as to their color codes, none bad. Cleaned all of the switch contacts with cleaner and alcohol.

I took the antenna assembly a part and cleaned it, tested the loop and it was good.

I powered up on a variac and the radio played. The BC was right on, I did pick up stations on the higher frequency band, I took the radio on vacation to the ocean, from the shore i picked up beacons in the fishing channel.

A fishing captain bought the radio from me after he saw it work.

Be patient, it did play very well.

Mitch
