Hi All;
Well I got something coming thru the set.. After playing with the various compensating capacitors, I got the Oscillator frequency close enough to start receiving stations.. I still have a ways to go to get the last 10K or so, but at least I know it is workable..
Would I need more capacitance or less to get the additional 10 to 15 K out of the Oscillator ??
I found that even moving one of the compensating capacitors up and down over the coil its mounted above, will make a difference in the oscillator frequency.. And of course touching the cap with my fingers will do the same..
I have an old Plastic stick, from Radio Shack that almost fits over most of the nuts that need adjustment.. I have had it for years..
Since I am using as my first IF a Miller 455KC IF can, and it has long leads to it, I have lots of squeeling and such.. So, I am going to put in the 1st IF can the IF Transformer that I bought from "Plaything of the Past" once I figure out how to wire it correctly..
This can has 4 wires coming out of the bottom, and I need to change it to 3 bottom and one on top.. I know how to find the two seperate coils, I just have to make sure they are orinated the same as the old one.. And that should eliminate much of the squeels and such..
THANK YOU Marty
