[R-390] Antenna Connectors

[Bill Abate]

Barry,

I replaced the 'unbalanced' connector with an SO-239 but I did it 
differently.  The original connector was bashed in, so I did not have 
anything to loose.  The connector is merely soldered in.  I removed it 
(forcefully) and cleaned up the residual solder in the socket of the 
relay housing.  I then removed the flange of the 239 and trimmed it 
slightly on a lathe so that it would fit the existing opening.  Then I 
soldered the SO-239 to the relay housing.  Then you just have to 
reconnect the center connector.  Not hard but you need a lot of heat for 
solder to flow on that massive housing.  Everything else stays the 
same.  In effect I eliminated an adapter.  Then I grounded one pin of 
the twinax connector.  I think I swapped the mini bnc's as is documented 
elsewhere to connect the antenna to the RF coils.

73,

Bill, K3PGB
