One of my complaints about the SRF-59 receiver has been the difficult
to use tuning knob. Looking at the SRF-39FP, it was evident more of
its tuning knob was exposed. So I decided to see if I could improve
the SRF-59. Using a small hobby file I carefully remove some of the
plastic from the case. Now it's a little easier for my arthritic thumb
to turn the tuning dial. There is a photo at http://ph.groups.yahoo.com/group/ultralightdx/photos/view/5165?b=7.

Now if I can figure what can be done about the stiff turning variable
capacitor.
