If you come across a problem like that hum, you should solve that problem before charging ahead and possibly wasting your time and effort. One thing that you could try to get rid of the hum is reversing the power plug on the radio. Has that radio been recapped? There are caps from the power lines to the chassis in that radio as well as in the SG-8.
When you get a new piece of test equipment the first thing you need to do before using it is to confirm that it is working right.
Do you have a well working AM radio that you can use to see if the generator puts out a signal that you can pick up at the right place on the radio dial? That would test the generator frequency and modulation at least on that one band.
The frequency counter will not be able to test for modulation very well.
