Wayne, Do you use a counterpoise with the whip? Bill
Yes, 16', although a somewhat shorter length will also work and may be preferred over some terrain. Without any counterpoise wire, at 14 MHz, received signal loss will be minimal but your transmitted signal will be some 8 to 16 dB down. At least this was the case in the tests I performed.
The KX1's autotuner helps because the Maldol whip is really cut for the high end of the 20 m band. In fact I often clip an extra 12" of thin, stiff wire onto the top of the whip, making it a total of 60 inches, and this results in a better match in the CW portion of the band. It also improves the transmitted signal by a dB or two in range tests (at about 50').
I managed four on-the-hoof QSOs during my half-hour walk today, including VA3RAC -- not bad for 1.5 W and a short whip ;)
