Model 41-296 LO problem - BC band
#6

I reinstalled the tuning condensor after cleaning it very good and burnished the leaf spring contacts, and rotor where it rubs them, etc. No change in the problem on the BC band. At least the condensor looks nice. It has a good ground, no problem there. I soldered all the riveted lugs in and around the osc and rf sections to the chassis, and as a feel good thing, I installed some screws with star washers on the chassis with lugs and jumpered the riveted ground lugs to them.

Next is getting into the bandswitch with something to clean the contacts, etc. Other than the bandswitch, there just isn't that much in the Osc section used on the BC band! Should be a no brainer, but I've not found it yet. This is probably one of those things that will hit me like the snake I didn't see all along. Just wish it would hurry up and bite!

Thanks!
Brian
