Re: [TenTec] Omni C + SB200

[Ken Brown <ken.d.brown@verizon.net>]

The SB-200 needs to have a 150 (approximately +/- my memory loss) volt 
DC line pulled to ground to key it. Using a relay driven by some lower 
voltage transistion output from the transceiver is one way to do it. Not 
the only way though. I have seen circuits in QST hint and kinks using a 
HexFet and a few other components....You will still have the noise and 
slow response of the relay(s) inside the SB-200. I wonder if anyone has 
built a QSK conversion into a SB-200. I think this would be much better.
