I have been using the W2 for about 3 years and am very happy with it. Now after upgrading the firmware from Release 0.96 to 1.00, I notice that it no longer displays an SWR of 1.1 but jumps from 1.0 to 1.2 when i slightly detune the antenna. At Elecraft, apparently, they could not reproduce this. Has any one else noticed this anomaly? 73 Richard
