RE: [drakelist] R7 audio

[Goss, Ed]

I had a problem with my R7A that sounded very similar, even had the crackling noise.  Turned out to be one of the circuit boards (I can probably find my notes to tell you which one), but the fix was to pull the board, clean the contacts, and apply *small* amount of DeOxit before reinstalling board.  I ended up doing this with all the boards.    --Ed G--   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of DW Harms Sent: Friday, May 26, 2006 6:45 PM To: drakelist@www.zerobeat.net Subject: [drakelist] R7 audio Drakelist de PA2DW,   I am using a R7 in combination with my TR7 for some time now, with utmost satisfaction. What I do notice though, is the difference in the way the R7 sounds in comparison with the TR7 receiver. Especially with the AGC in position “fast”, the audio sounds very much like it is saturated in some way and there is a kind of crackling noise coming along with the received signal. I always thought it was my R7 that did that and it was something on the list to fix. But today I visited Evert PA2KW and his R7 did sound very much the same like mine! We went over it and tried tweaking the AGC but with no success… Now I wonder if others experience the same and if there is a fix for it. It surely must have something to do with the AGC circuit.   Evert and I decided to go and search for the service manual of the R7 which we don’t have, so any source for that will also be highly appreciated!   VY 73, Dick PA2DW has notified the sender that this message has been received.
