Decided to have some fun this morning.

The RBC is working great on 14 CW

Could only hear FT-8 on 17M and 21M (strong signals).

The radio will not cover 10M,  but here's some 11M "stuff".....

Here's the pair that will be replacing the ones I'm selling:

They are both "first editions" -- contract NOs-73056 from 13 April 1940.  They are complete, and I look forward to getting them working.

Couldn't find an CW on 80M..... but I've used it a lot on 80 CW in the winter months.

I've used these radios for several years and it's time to find them a new home.

Price is $180 for all 3 units.

Pick up only.   Will have them at the Berryville VA hamfest on Sunday Aug 2nd.

All three units are sold as is.  They work well enough for casual enjoyment on CW, SSB, and SWL, but I'm not sure everything is 100% functional according to spec.

Reason for selling:   I have an early model all black RBB and and early model all black RBC that will be taking their place.
