Title: Johnson 122 VFO Post by: W7SOE on July 22, 2007, 04:47:21 PM I am trying to get one working... The two high frequency positions are not working. I have cleaned and ohm'd out the switch, it's ok.
Those two settings have their own coil and caps, I am going to try replacing caps. Unfortunately I am having trouble getting the manual off Bama, can someone send me page 23 (the first page of the parts list) if they have it? Thanks Rich Title: Re: Johnson 122 VFO Post by: WA1GFZ on July 24, 2007, 10:13:19 PM check the screen dropping resistor. It started life at 18K but my last one was 40K. (It looked normal) I replaced it with a Wire Wound 25k 10 watter.
I think I have a manual copy at work but got it off bama. I will check in the morning.
