[Milsurplus] Difference between RBC-1 and RBC-2 receivers

[Dave]

G'day all,

I've just started replacing a butchered set of front panels on an RBC
receiver with a nice clean panel. Unfortunately, I have no ID tag and I am
trying to work out which version RBC I have.

>From the manual, I have been abls to establish that it is at least an RBC-1
with serial number over 1000. This due to the placement of the CW oscillator
vernier capacitor.

So far, I have not been able to find a reference in the manual to the
difference between RBC-1 (S/N over 1000) and the RBC-2.

Can anyone shed any light on this, please.

Cheers
Dave
