Philco 40-180 Tracking Issue
#10

Terry, hoping that you might be able to help here. Because good wasn't good enough, I attempted to fine tune the IF even more after this thread. In the process, I lost all dial control, only presets. (See other post. Resolved). Now I have a working radio, with good sensitivity, but the low end won't track again. 560 is at 590. 780 at 800, 1000 at 1010, 1400 is spot on. SW band tracking is off as well. Interesting on SW, I have nothing below 9 MHz, the noise floor just disappears. Police appears to be ok. AM is fine.

When I adjust the Osc fins, I see minimal change. Cap 19 is loose. When I tighten it, It only makes 560 climb even higher than 590.

Any other ideas?
