Updates to GPR90 receiver?
« on: November 27, 2021, 06:34:13 AM »

I have owned a GPR90 receiver since about 1965. Made a number of mods back about 1980.  Doing some restoration now and wonder if there are any factory service bulletins that I should incorporate or other mods worth doing? Didn't find much in Google search.

I finally ordered, and received my ESP DD-103 last week.  Ron went ahead and set it up for my KWM-2 and it works like a charm.  Will do some final calibrations against the receivers xtal calibrator, but I am very please with it!
