[ARC5] slightly off topic- RMCA

[scottjohnson1 at cox.net]

All-

I have several Marine radiotelephones about which I would like to know more.

 

The first is a RMCA Cruisephone 55, late fifties vintage, 6DQ6 modulated by
two 6L6GCs, transistor 12V power supply, five tube receiver with marine 2-4
MHz band (crystal controlled), plus tunable BC band.  Very nicely made.

 

The second is a mid-thirties RMCA USCG motor lifeboat (rescue boat) radio
telephone, 2-4.4 MHz.  I have two- the first has a 12VDC dynamotor supply,
with a roughly 50W transmitter (two 807s modulating two), the second, larger
unit is probably 75-100 W (four 807s modulating three)  The have provisions
for remote control and are waterproof with the cover dogged down. The
receivers are T-104, the low power transmitter is a t-102, and the high
power is a T-103.

There is also an antenna coupler for the larger unit.

 

I have searched most of the resources and have come up empty on these
radios.  Any help would be appreciated.  Would like to find
manuals/schematics, personal knowledge, anything!

Thanks,
