A 100W 6m amplifier shouldn't be too difficult to homebrew. Check Communications Concepts for several amplifier designs that cover HF-6m. They have a 20W driver amp you can get the parts for $103 (ht
I've got an idea: Use XML. Forget the ancient ones who will say that XML was considered for Cabrillo but not used because it's harder to program for. There are SO many XML libraries out there that yo

I have to agree with Les' assessment, especially when one looks at the cost of adding the 1.2GHz module to a TS2000 either by purchasing a TS2000X or by adding it later, then comparing it to the cost
Jim, might it be appropriate for the ARRL to either announce the rules clarification on www.arrl.org or in QST? We might be a bit late for QST, but something on the web page might reach a few more op

Just thinking out loud: What if you didn't count their QSOs in your submitted logs? In other words, hand them the HT, let them work you for the contest, but don't submit those QSOs as valid. That way
