Latest on the 37-650

Well, I have the chassis back together, having torn it down again to check the wafer switches. When I did, I remembered I had changed the leads. As mentioned in the other posting, the resistance was almost three times the desired amount. I replaced them again with a donor set, and they were almost spot on for resistance. I also ohmed out the other BC band coils, and they were fine.

So, I went through and attempted to adjust it. Everything seemed to go well, and now I have SW 1 & 2. I also have the upper third of the BC band, but below 900 it is still squawky, squealy, and burring. I have tried everything I can think of... Any more ideas? Should I just keep attempting to adjust stuff, or is there a potentially specific cause I can start to look for, now we know things are going through that far...

Ideas? Comments?
Thanks!
Scott
