Thanks for all the pointers. I've come to a new intense dislike of electrolytic capacitors while debugging my clock. One was really bad in the radio receiver board's AGC circuit, causing oscillation, so I ended up recaping every electrolytic I could find. Probably not too surprising in a 20+ year old clock.
The clock stopped syncing about 5 months ago. I did the cap replacement, then realigned the receiver and tone decoders, but still no go. That's why I was trying to cut my problem space in half by injecting a known good audio. I thought it would be a no brainer for the clock to sync to injected audio, but that hasn't gone as well as expected. The clock isn't a source of time or frequency for me anymore, but I want to keep it alive for the nostalgia factor.
