One morning, I headed to Delaware to have lunch and to activate US-1730, Alapocas Run State Park. It was also along US-9878, Northern Delaware Greenway National Recreation Trail.
I put up my homebrew delta loop with 4:1 balun. With the tuner on the X6100, I could get 1.5:1 SWR on 20M. For kicks, I only ran 1W and made 23 contacts calling CQ on FT8. The location was very quiet for listening.
On 15M, I got Italy with 1W.
I tested a new 5200mAh 12V Li-Ion battery, and it worked for the entire activation. It dropped from 12.3V to 10.9V or so which was plenty for the radio.
