SX-117 revision B to C


 

All: I have read the very good explanation of the different revisions to the
SX-117. Mine is a post-B model, which means that the notch filter doesn't
affect the AGC response.

I am inclined to revert that part of the build back to Rev B so the notch
filter behaves "correctly", but before I look at this I'd like your opinions
on the wisdom of doing this. What do you folks think?

Thanks,
Dave Maples


 

I am also interested in making the same change.

Dave - I have a late model, think it is a D but can't recall now.? My biggest complaint was that the AGC and S Meter responded strongly to off-frequency strong signals.? I made the change - think it was a one wire change - and that solved the problem.? There were no negative side effects and the change is easily reversible.
