Here’s a quote from Wes describing the equipment that he was using on his end:
I hope that my signal was OK when we worked. I was in the midst of wrapping up a frequency synthesizer project and had it running on the rig for the first time. When I heard you on 20, I could not resist calling. You were the first contact using that source. But I then discovered that the PLL was oscillating. It was a low level oscillation and didn’t present an obvious problem with regard to what I heard on the air. But it was there. I have since then changed the phase/frequency detector circuitry and have eliminated the oscillation. I am not thrilled with the 74HC4046. I get much more repeatable performance from a dual D FF with a NAND gate.
