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
