Re: [Elecraft] [K2] Low power output

Hi Don, many thanks for all kind help and ideas. I will try to call him in order to explain all of these steps to be checked. Most important is to double check what the real power is from his K2 as I do not know if he measured the output power correctly with his external equipment. Again Don tha

Re: [Elecraft] [K2] Low power output

Petr, The specification for the K2 is for 10 watts or greater. Most will go to 12 watts on 40 and 30 meters with an adequate power supply voltage while few can achieve 15 watts on all bands. There is nothing specific to the KPA100 option that would cause low power output from the base K2.

[Elecraft] [K2] Low power output

Hi folks, my colleque got as birthday gift from family the K2. All seems ok, receiver works excellent. The only issue he found is the low power output thru all bands. He can not get 15W but something below 10W... He mentioned in last email that preview owner had installed KPA100 option which has b

Re: [Elecraft] K2 Low power output

Dave, It may be that the wattmeter in the KPA100 needs calibration - and is the most likely reason. Dig out the KPA100 manual and look at page 48. Do the SWR Bridge Null Adjustment first. Then do the Power Calibration. There may be some variability in the calibration from band to band because

[Elecraft] K2 Low power output

I recently acquired a very clean K2/100 with external KAT100 ATU. I have a K3/100 and its power output agrees closely with the readings of both Bird and Elecraft W2 watt meters. According to these watt meters the K2, set to full power of 110W, puts out about 80 - 85 W into a dummy load (SWR re
