[Elecraft] Balun and Range of KAT2

[Ignacy (NO9E)]

My KAT2 matches very well on 1.8-10 MHz but the match is less certain on 
14-28. With portable antennas, usually one of 10-12-15-17-20m bands does 
not match well ( SWR > 3) , and one or two are around SWR = 2.0.

As an experiment, I tried matching a 2.7 K resistor. Matches on 160-30m 
were quick and to SWR <=1.2. Matches on 20-10 took much longer and SWR 
was 1.5 to 8. A simple test with Cs and Ls seems positive. Could my 
inductors or capacitances be wrong, or is this due to stray C/L and 
higher relative tolerances with smaller coils?
