I've never had much success with getting my old EFJ Matchbox to play well for me on 30m, even with moving the tap points on the input - there was always too much heat and too high a VSWR. The best solution I've found for 160-30m is a balanced matching network with a pair of roller inductors and a 1000 pF variable cap, with an additional 2000 pF to switch in for 160. I tend to run more QRP than 100w (never more than that), so every fraction of a dB of loss reduction certainly helps. 73 - Al, K2ZN |
