OK, i was able to ge the signal generator set to 455k and get a tone coming out of the speaker when I connected it to different test points from the directions to test the am receiver. I would suppose that proves the modulation works. Only thing is when I hooked it up to a test point the directions said the tone should be quite a bit louder than it was at another point, but it is about the same volume. I will have to find out why I suppose...maybe because it isnt aligned yet or there is one resistor I understand might be the problem...Hopefully not the switch tha changes it from am to fm to sw, etc., that would be very hard to do anything with.
