P.S. It looks like the T2 or J-Field isn't able to read the power output setting of the HPT435BT, because the T-LS never did show anything more than "---mW" in the display, even when I was getting corrections.
In the next version of J-Field this should be working properly. When I test different power outputs with the HPT435BT in the test version of J-Field everything works correctly.
