[Drake] R4B antenna connector

[WQ9E at btsnetworks.net]

John,

I have a couple of R-4B receivers (and several others of the 4 line family) and have worked on several more and all had RCA jacks.  I have never seen any documentation for a different jack on the R-4B although I vaguely recall that some of the SPR-4 receivers were sold on contract with a BNC antenna connector.  I am fairly certain your R-4B was modified by a previous owner.

I would just leave it as is since the hole probably was enlarged to take the BNC connector AND the BNC is a better connector anyway.  I especially dislike the RCA antenna jacks used on some Heath and Collins gear.

Subject: [Drake] R4B antenna connector 

I have acquired a Drake R4B receiver and it is different from all my other 
Drakes in that it has a BNC connctor on the rear of the chassis which is labeled 
"ANT" and next to the antenna connector  is another BNC connector with the label 
"spare" .

Did any of the R4B receivers come from the factory with two BNC connectors on 
the rear of the chassis in those positions?

Is it possible that the RCA phono jacks were replaced by someone with BNC 
connectors? Would the holes in the apron of the chassis have had to have been 
enlarged to install the BNC connectors? If that was the case, it would probably 
be best to leave the connectors as they are/ Your input, please. Thanks and 73, 
John, K5PGW
