I will set up a meter and monitor the 8vdc point I connected the control to. I'll let you know what I find. I love these older radios so I am hoping this one can become more manageble. I will say that when I talk on it (always LSB) It worlks great. I just need to keep making the adjustment...

The radio was stable before but I am going to return it to its factory default as a test. The drift is on both transmit and receive. I did clean (deoxit green) the control and it seems to work fine. The drift is interesting. It is always center to low, never high. It will move down to 9...

Good Day Men, So, I have this 1985 President Jackson that I wanted to open the fine tune clarifier (course clarifier is open from the factory). I used the method shown below for this. The radio drifts more than I expected so I was wondering if anyone has seen this before or has a solution...

Hey Everyone, So I have this SB-520 that I talk on once in a while on SSB and it sounds terrific. I have not talked on AM in a few years but someone was local and asked me to jump on. The modulation was very low. Around 30%. I tried a few mics and nothing hepled. I put it on the bench and...

Gman, For us non-tube folks, is the 201A a non-pll 40 channel radio? Also, is the issue you are trying to address a problem with the 40 channel switch/dial or are you looking to tinker some?

Hey Cable Guy, So, I have a Stalker XX and it has the 8734 chip in it. The Sams manual for it shows the 8734 as well. I think that the export version of the Stalker XX may have come with the 8719 and that may be the schematic that you have. The Madison V2 is shown in the Sams 230. It shows...

Ok, so the other pics I took are attached. I hope they help!!! I had returned this mic so I cannot get any other pics for you.

If your question was regarding the wiring of the switch I found this in the Turner Wiring Handbook.

SL, I worked on a single transistor M+2U and that was the schematic I used as I did not have one for it either and it worked well enough to get me there. A pic of the mic is attached but I did not take it for the parts detail. It was to show the owner that the element was in good shape overall...

One thought that was not expressed here is what someone’s expectations are. Are you expecting a certified watt measurement or are you expecting an “about” measurement and, what are YOU comparing it to? If I align a radio using a Bird, Telewave, Dosy or any other non-Amazon basic meter, when I...

Ok, so it is fixed by using the @TM86 method. I used a label from a pack of onions. I did tape it to the ribbon cable for stability. Thx TM!!

Hi Everyone, I dusted the Stalker off the shelf and wanted to do a quick test before I worked on the clock. The it sounded strange on TX so I went through the alignment to check things. The PLL alignment was fine until I got to the final stage. The 7.8025 and 7.7975 were verys unstable. They...

Thanks soo much!! I need to get the Robyn 520 done and then the Stalker goes back on the bench. I'll keep you posted.

Just......Holy Smokes!!! That's awesome!!
