[MRCA] SEA 112 HF Marine Transceiver

[mstangelo at comcast.net]

Chris,

Hope you find information on the rig. For the record my 322 operates without the tuner.

Did you pick this up at a Marine Consignment shop? I've heard there are Marine Consignment shops in CT and RI where you can pick up marine radios. I'd like to check them out the next time in am in that neck of the woods. Unfortunately I haven't found any MArine Consignment shops in NJ.

It has a big socket on the rear panel for interface with a remote antenna tuning unit, it’s not clear what the direct output from the radio expects to see as a load.  It’s also not clear what the actual channel frequencies are set up for as there is no direct frequency readout indication, just channel and band switch positions.  I suppose that I can sweep the receiver with my URM-25 signal generator, using my HP freq counter to give a high resolution of the sig gen output to get at least some idea how it is set up.
