Mike, I agree, I personally use a 'scope with its 10X probe connected directly across the dummy load for my peak indicator - just watch for the highest deflection on the 'scope and it is 'Spot On' - easy and no ambiguity.
For those not having access to an analog indicator, the K2 display does work fine, but one must tune slowly because the digital display takes a bit of time to 'catch up' - with fast tuning, the peak can be missed. Bottom line - if you have anything analog that will indicate the peak, use it, the peak will be more obvious than with the digital display. That includes inserting an analog SWR meter in-line with the dummy load - no matter that the SWR meter or Wattmeter is inaccurate, you are interested only in the peak when doing this tuning, not the absolute power (measurement of the power comes later). The original question was about determining the peak during the receive pre-alignment, be aware that this is only a preliminary alignment, the better (more precise) alignment will be done using Transmit, so if one gets the receive pre-alignment reasonably close to correct, the final peaking can be easily done with the transmit alignment. 73, Don W3FPR > -----Original Message----- > > G'day, > > | L's - and the LED Display changes little or flickers > | side to side.
