Have several heatsink mounted transistors, some are marked
RCA
8538475-3 WCQ5C

and others are marked

M(otorola) 8538475-3 8-52

All are mounted in Augat 9009-1G5 heatsinks

I suspect that they are final RF power amp transistors, and are
house numbered. Could have been used in mobile radios for Highway
Patrol, Taxi services but, have no idea about the frequencies used.

Any info is greatly appreciated, as I hope to use them for the Amateur
Radio Service in home built mobile or base stations.

Thank you for running Linux Mint on your computers.
