[Milsurplus] RBC

[Hubert Miller]

Sorting out manuals today, i couldn't resist taking a look at the RBB/ RBC
Prelim Manual. This looks like a pretty

impressive receiver. The mixer tube is actually one of the lower noise tubes
today. The selectivity according to 

the manual, sounds to be good, altho the prelim manual has no spec for this.
Does the final edition of the manual

give this, and if so, what are those?

I'm thinking an outboard freq counter would bring this box up to speed and
it would be a fine AM-CW DX machine.

Maybe a plug-in product detector somewhere. 

I wonder if a limiting factor is the 6SK7 in the RF stage. Maybe a cascode
plug-in adapter would help; maybe not.

I am VERY impressed by a receiver having a 5-gang tuning capacitor with 4
tuned stages ahead of the mixer.

Amazing. Never seen such on any other receive i am familiar with.  

But the limiting factor for me is unfortunately, the size. I'd have to look
around for several other boxes to jettison

to be able to have an RBC, and then if really liked it, i'd have to have at
least another. 
However, after checking out the manual, i'll definitely take a longer look
at the next one i see at the hamfests.
