Philco model 38 code 121 not receiving signal.
#12

Hi Stormlord and welcome to the Phorum.

I am scratching my head because, even if the primary of the antenna coil is bad, if there is nothing wrong with the secondary, hooking up a long wire to the convertor grid should definitely work.

You stated that you used the "2 Radio" routine to test for the local oscillator of the set in question and found it functional? The worst part of the autodyne circuit is getting ot to oscillate. The antenna coil has nothing to do with that; the oscillator coil does. If you can detect the local oscillator, the next step is to determine if it is 460 Hz above the station being tuned in.

Can you receive stations in the shop that you are working in? There is an amazing amount of RF interference to be found in houses nowadays what with cell phones, the Internet of Things, computers, video screens, CFLs, LEDs, etc. If the amount and nature of noise changes as you run up and down the dial, then you may e receiving too much interference.

Tryanother location. Good luck
