Don, Unless you do an A/B test using the same antenna for 20 meters and a similar transceiver, it is difficult to make any valid judgement. Yes, 40 and 20 have very different characteristics, and vary themselves a lot from day to night - it is all in the propagation conditions at the time.
A low level signal generator such as the Elecraft XG2 or XG3 can be used to do an MDS measurement on each band - that will give you the real information you seek, but I do not know of another valid method other than the A/B comparison. 73, Don W3FPR On 10/3/2011 3:44 PM, Don Baucom wrote: > I have a K1 with a 40/20 filter board.
