So, first I checked the tuner's plates, there was no shortage. Then I made the loop and checked the +455K.C.It is OK in the middle of the dial but gets worse getting to the lower side of the one.At that time my J trimmer was maxed out and the frequencies were matched with the pointer with about 15K.C. discrepancy.Not correct but not terrible. So now, to get 955 K.C. (540 +455) I had to bring the J trimmer 1/2 way down it's travel, quite an adjustment. After that checked the 800K.C station -it was at 650 on the dial. In another words- same issue as before.
I have a question- does getting +455K.C mean that that osc. coil is wound correctly? I have heard, that even slight change in the gauge may affect the coil operation. Also, I had not mentioned that before, original coil, after the 60th turn had 1/8" gap, then the rest of the wire was wound. Does it make any difference that I did not maintain such gap?
