T3NR Elevation Bust Problem: Calling All Thinkers

[avoidthelloyd]

As painful as it has been, I'm glad I discovered this and it has been addressed. Has anyone used the T3NR as a base and checked that it is fixed? I'm too gun shy to try it... haha. It's a simple test. Measure the HI and start the T3NR as a base, then measure your HR and stake out to the base point while next to it on fairly level ground.

In JFIELD, when you setup the 'Remote Base', do make sure the 'Antenna Type' and also 'offset' are specified and applied to 'the base'.
