Updates will be posted as new information becomes available.</strong></p></blockquote> <p>Last Friday, I activated a couple <a href="http://pota.app">Parks on the Air</a> sites with a friend using his <a href="https://www.eham.net/reviews/view-product/3046">Yaesu FT-857</a>. After parting ways for the day, I intended to activate a few more parks with my <a href="https://elecraft.com/products/kx2-ssb-cw-data-80-10-m-transceiver">Elecraft KX2</a>. I was surprised when my KX2 would not tune the EFHW I brought with me. The best it could do was 25.4:1 SWR on the 20m band. Normally this tuner can handle <em>anything</em> <strong>and</strong> I was feeding it a resonant antenna, minimal tuning required. I tried swapping feedlines on the EFHW, no luck. I tried disabling the tuner, reenabling the tuner, no luck. I tried swapping feedline, again no luck. I tried pulling the EFHW out of the tree and putting up a linked dipole, still no luck. Unfortunately I didn&rsquo;t have a backup radio and was running short on time and decided to pack it in.</p>
