Lucky for you that I took good pictures of mine. :)
Thanks, Jim. Yes, lucky for me!
I have done some additional troubleshooting.
The good news: static power supply regulation seems to be right on on both boards: 13v, 9v, and 5v, all well within Drake manual spec, however I have not yet checked this for variation over time. My guess is this will not be a problem.?
The bad news: further testing per the Drake manual Performance Checks section shows that the RV75 does not initialize to the published freq of 14.250.00, but is something like 14.441.00. High & low freq limits are also well above the published spec. Fixed freqs also do not load correctly. At first glance all of these would seem to be related. So. somethong is not right on the digital board.
Given the farvorable results on the voltage checks, I will toubleshoot the digital board first and then come back to the drift issue reported earlier.?
I am already well past the point of knowing more about the RV75 than I ever intended!
