[CQ-Contest] Output pad for running QRP?

The best way I found (with Icom radios, anyway) is to inject a small
voltage into the ALC jack.  With Icoms it seems to be 0 to -4 vdc,  with
-4 volts completely shutting down the output on my 765 and 746.  Other
brands probably vary.  I built a 9v battery supply - voltage divider
with a 10 turn pot - and it allows me to accurately set output to run QRPp
(100mw).  Hope this helps -
