You shall have it. Sawdust is flying. I just tried my beacon on the
antenna with NO coil and guess what the results were?
Even though I used a NTE 128/129 pair final (instead of the 2N2222/2N3907
pair), and even though I put heat sinks on those transistors, they got hot
before I could get through a QRSS30 "U" ... made it through the first dot
and shut 'er down. And I mean HOT!
So, the coil is coming, and I'll post the pictures when completed.
Thanks to everyone for the help,
Eric
