[MRCA] GE Portamobil

[Ray Fantini]

It’s a six channel solid state radio with the Broadcast receiver included. Figure I would drag it out to Dayton and sell it for $20 for someone who wanted a mobile radio for 160 AM, don’t know if it would go up to 80 or not. If anyone is interested I can put up a picture. Has the mounting bracket that I figure would be way more rear then the radio. Wonder what they used for an antenna being back of set is isolated signal wire feed so the radio must have an internal loading coil but going to assume that they went to some form of whip antenna. Also recall that radios for HF had to have ground plates on the bottom of the hull. Would speculate that some high voltage was developed along the antenna line and on the antenna.

That's the old obsolete standard Civil Air Patrol repeater frequency pair.  Pairs like 148.125/143.550 seem to be commonly used now.  After 9/11/01, CAP and MARS frequencies started being treated like Top Secret SIOP-ESI information due (I guess) to the very vital highly-classified traffic carried on their networks, not to mention the self-importance that guarding FOUO information gives to the privileged possessor! :-)  When I was in MARS and CAP in the 1960s and 1970s, we'd pass out mimeographed sheets with net times and frequencies to encourage listening and to recruit members...even when it was popular entertainment for some left-coast types to interfere with phone patch traffic for Vietnam-theater servicemen.

That Marine Band AM set sounds interesting.  I've collected several of that type since they started showing up at hamfests 45 years ago.  I like the sets that have an AM broadcast band receiver built in.
