There is nothing else in between to cause a power drop. Where else would you recommend I look for the source of my problem, if not in the transceiver itself? 40 watts may only be about 1/3 of an S-unit, but that isn't the point. The point is that my rig is not performing as it should. I would like to fix the issue, in the most cost- and time-effective manner possible. If there are tests I can run to help isolate the problem, I'm open to suggestions. Thank you. --Ian Ian Kahn, KM4IK Roswell, GA EM74ua km4ik....@gmail.com K3 #281, P3 #688 HRD v5.x/6.0 Test Team On 12/22/2012 6:13 PM, Ron D'Eau Claire wrote: > And you'll likely find the cause of your "low signal strength" is > somewhere else, since 60 watts is only 2 dB - about 1/3 of an S-unit - > below 100 watts. > > That difference is not usually detectable on HF given normal > variations in propagation that go on constantly. > > 73 Ron AC7AC > > -----Original Message----- > > > Have you run "Calibrate Transmitter Gain" using the K3 Utility from > Elecraft?
