Default Re: Heathkit RF1U Signal Generator Restoration

Not surprisingly, given my love of Heathkit, I have an RF-1u, however I've never been 100% happy with its modulated waveform. When I once used it to line a set up the tuning points were different from a generator with a more textbook modulation shape.

However looking at the output spectrum doesn't show any lop sidedness to the side bands (see attached)
