That's good news.
Auto tuners are not a good idea with QRP rigs like the QMX, QDX etc. The tuning process goes through a number of trial settings that will give very high SWR values and may damage your radio. Better to get a manual tuner. There are a number of good ones made for QRP work and quite inexpensive as kits. I use a Kanga MTM-ATU which comes as a kit and I think prebuilt is desired.

QMX update. I removed one turn from L510 and 513, 30m power improved but 20m no change. New version of T501 built and certainly helped except 20m. New version L401 built and a huge improvement, all bands in pass band except 80m where pass band is a bit too high. Currently using a Sandpiper ?MV6. Are most people running an ATU? If so, thoughts on the budget ATU-10, it does look very sensitive to antenna match, no surprise.
