I just received a very old working RCA RBB receiver. I'm pretty sure I had an RBC as a very young ham. Once I get the receiver into position it will be interesting to see how it performs compared to my much newer Icom transceivers. 
Any comments on the RCA RBB? This one covers from .5KHz to 4MHz.

I don't see how the RBB will be useful given that it doesn't cover the 630m or 2200m band.  shrug.

As a historical / museum piece, the RBB is fine.

As a working receiver, forget it!  I think the RBB is a WW II vintage receiver.  They were designed when there weren't any 500 KW or 1 MW stations in service.  Selectivity and image rejection could leave a lot to be desired.

Try it for BCB & MW DX'ing or monitoring.  It could be interesting!

I agree with both posts above, the RBB does tune down below the AM broadcast band. I have an ICOM IC-7410 and a modified IC-735 that seems to Rx the 630 meter band just fine.
The working RBB is used as a conversation piece that tunes the AM radio band just fine.
Tnx, AA2UK
