Curt, The base K2 power reading is quite accurate if (and only if) the load is 50 ohms pure resistance. See my other post on the subject.
Since you have a K2/100, the included wattmeter should be as accurate as your calibration of it. Prhaps you should re-do the calibration - or possibly both your external wattmeters are not properly calibrated (see my other post for more info) 73, Don W3FPR -----Original Message----- I tried TWO good watt meters on the K2 and I found that the K2 is NOT accurate. The ONLY place I found it to be accurate is at exactly two watts. I also found that my K2/100 will go down to 100 Mw then jump to just over one watt, then to over to three and etc, it's not a smooth transition. I wish it would go from zero all the way up smoothly, but no way. My Icom is a lot smoother but will only go down to 1 1/2 watts. Working QRPP with my K2 requires 100 MW and thatâs all because it's too jumpy to set anywhere else. I don't have RF problems as far as I know but it sure is acting like it with the K2 but NOT on the Icom. That is my only beef with the K2 because my Icom acts more like a real QRP rig that the K2 does. k3ey k2/100 s/n 5417 "Darwin, Keith" <[EMAIL PROTECTED]> wrote: My K2 and my watt meter do not agree. When I set the K2 power output at 5 watts I get almost 10 according to the external watt meter. Setting K2 power output at about 12 watts gives something between 15 and 20 out on the external meter. At settings above about 13 watts on the K2 knob, I get the high current warning. This is all driving a 1.2 : 1 or lower SWR, btw. It leads me to believe the K2's power output is fine but it's ability to measure and report it is off. How accurate is the power output control knob supposed to be? I don't recall doing any calibration steps or alignment steps that affect that part of the rig. I have not (yet) measured voltage into a 50 ohm dummy load but am seriously considering dragging the rig, PS, dummy load & cables into work to have access to a scope. - Keith KD1E - - K2 5411 - _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
