In the ol days we would use a pencil or rub a bit of solder on the=20 face
real hams used ? acid to etch and raise the frequency,, I dont=20 remember
what the acid was but the local chemical company would sell a=20 bit
 
drill a hole in the mount face, tap it and use a screw to = apply
pressure and move the frequency around
