[Drakelist] R4C SSB Leakage

2012-08-21 Thread Bill Becky 
Hi Group  I have written previously about my R4C having signal leakage in the 
SSB mode only affecting the PBT control and S-meter levels.

Someone suggested that the 4NB was causing the leakage so I removed the 4NB and 
put some wire jumpers as I didn't have a 4NB plug, no change.  However I 
ordered a aftermarket socket plug to do a sanity check..guess what..it 
got worse!!!  Instead of a S5 level leakage it then went to S9 with the 
shorting plug??!!

I guess I've narrowed it down to something on or near the  NB4 jack underneath. 
So much for the sanity check..bizarre.

Bill,

 

Are the levels what they ought to be through the signal chain? A poor solder
joint that reduced normal signal levels could cause the relative strength of
leakage to rise.

 

Another possibility is that someone fixed something and the receiver is
now miswired.
