I love your PGXL amp and especially appreciate the latest firmware which quiets the fans at idle. I just signed up to the Flex Radio waiting list for the Tuner Genius. The HF Auto I use now at the base of a 43 foot vertical has only 26 uh of total matching inductance capability (16uh roller variable + 10 fixed) and uses the differential T design. The 800 watt Skanti commercial maritime tuner that I used years ago used a Pi network like the new TGXL. It had about a 100uh of total matching. I was able to tune 160 meters without any outboard inductance on almost any size whip antenna. I was wondering how much total inductive matching the TGXL has and how it performs on electrically short antennas? Looking forward to getting a TGXL!
