SG Frequency Change With Modulation
#6

You have to have a strong enough signal to the counter to be stable. If it is too weak, it jumps around. I use an Eico and it is very stable. I think it was one of the better units back in the day. The radio repair books will tell you to have the gen on for about 30 minutes before alignment. Now, in the days before those digital freq counters, all you had to go by was a known good radio and the pointer on your dial, and seems like they did pretty good. 

I note that on my AM radio transmitter that the freq jumps around some when I hit it with modulation. Steady when things are quiet.
