Thanks all, this is a cheap basic generator from back in the day and isn't in anyway stable. That's one of the reasons I bought a counter. I figured the counter was getting confused with the modulation and side bands and all. So I have no real way of checking if the RF osc. is changing when adding modulation but I suspect it is by the fact that I need to slightly retune the radio when adding modulation. It's been awhile since I had it apart but if memory serves, it has 2 tubes. One is the RF osc and the other the audio osc with a selenium rectifier!
