Ok. Let’s try this again…RCA 9TC240 Alignment

I wanted to do some basic function tests on the 8600. I've disconnected everything between the 8601 and 8600. I set the 8601 to put out a CW of 20MHz and I connected a cable from the 8601 RF out to the 8600 input jack on the front...at the extreme right. I believe this should make the 8600 a basic frequency counter. I get a real-time reading on the 8600 display that changes as I change the frequency on the 8601. This occurs when I have the scope button pushed in on the 8600. When I press the "CW Counter" button on the front of the 8600, I get a frozen readout of the RF frequency that does not change in real-time when I vary the frequency output of the 8601. If I go back to pressing the scope button, I get the real-time frequency read again.
