[TenTec] Amp Keying Relay Omni VI

[John Huffman]

Paul -

Thank you very much for the help.  That not only solves the relay problem, but 
also silences the Omni VI internal relay.  Great solution.

I've ordered the Jackson Harbor kit.  At $11 I don't think I could get the parts 
for much less.

Again, thanks for the help.
