Don etc. May I suggest setting the K-2 to maximum output power, say on CW, and then adjust the TX level from the Signalink to produce about 30 watts output. Do not change the power level on the K-2. FYI - This should work very satisfactorly for any radio.
With a PSK signal there will be some variation in output level depending on if one is looking at idle data or text data. 73 Bob, K4TAX > Don, > > I'm having trouble with this approach on 40 meters. > > I set the power on the K2 to 30 watts and then adjusted > the TX volume on the SignaLink as high as I could without getting any > ALC reading. > > When I do that, I essentially have zero power output.
