Hi All;
No good on the 34.. But I have made significant progress on the Breadboard.. Since, switching the wiring arround on the 1C6 so that the dropping resistor has the correct voltages on it.. And taking the Cap out of the circuit that was in parallel with the Coil, it Now will Oscillate.. It is not at the correct frequency, but it oscillates..
I decided to Re-Count the number of turns I had on the secondary coil.. It seems that I had lost count more than I thought.. I re-counted by marking with a black marker every ten turns, and found that instead of 110 turns I had 162 turns..
I took off two turns and measured the resistance for a base measurement and then took off 10 more turns measuring each time with my VTVM.. After getting the VTVM going again.. (Another posting).. when I got down to my goal of 100 turns I tapped it to a terminal and wrapped 10 more turns and put it to another terminal..
When I tried the oscillator at the 100 turn mark the Frequency was a little high.. I tried it at the 110 mark and it was Higher yet..
So, I took off the extra 10 turns and then took off 5 more turns tapped it to a terminal and put the remaining 5 back on just in case, and terminated it..
I tried it at the origional 100 turn mark, still too high, tried it at the 95 turn mark it was almost correct, and with a little tweaking on the grid leak Variable Cap I got it to Oscillate at about 1010KC..
Which led me to my Tuning question, (another posting)..
THANK YOU Marty
