Well it turns out in the past I did have a signal generator that was capable of going down to 177.5 KC but unfortunately I made the mistake of trading it with a friend of mine at a local computer store in town for a Hewlett-Packard HP8640B Signal Generator from 1972 that I didn't realize wasn't capable of going down below 455 KC without some serious modifications that are a little over my paygrade to do, and the signal generator I had that was capable of going down to 177.5 was a Heathkit Model SG-8 Signal Generator that had a range of 160 KC to 220 MC and I had already made the modifications on it so that it could use BNC connectors rather than the old Switchcraft style Microphone connectors that came with it originally, unfortunately the computer shop that the guy I traded my old Heathkit Signal Generator to is in the middle of moving to a new location and they have no phone number to get a hold of them at currently so I'm kind of stuck right now on this radio because as I stated in my previous post, I think the IF Alignment is way off on this radio and needs a realignment and unfortunately the only signal generator I have right now that has a physical tuning capacitor in it that I could do the "tack a capacitor across the tuning capacitor" modification to is a unit that has the old style Switchcraft style Microphone jacks on it and I don't have the proper RCA to BNC adaptor jack to make it so I can hook it up to my frequency counter I have (I used to but it somehow got lost when I was moving from my old apartment to my new house.) There are a ton of Heathkit Signal Generators for sale on ePay but the cheapest one on there is $50+$20 for shipping, and its being sold as a "Parts Only" unit.
