Quick update.

I am chasing the 52mhz signal that is mixed at Q105.

I am getting a signal at Q109. Can see a signal that peaks every 1mhz while tuning the main vfo. Can’t see anything beyond Q109, the led drivers are not getting signal to turn around t on/off

Will remove Q109 and test it. Seems to get a signal at the base that peaks every 1mhz but nothing at the collector.
