[TenTec] SOTA RADIO - Bioennopower batteries

[Reed]

Rick, there are 2 sets of wires.  One set for power and a plug wired for 
the ACC jack on the FT-817.  What ever the input voltage is, 12 to 14 
volts, is what keys the relay at 54 ma. This is what I measured with 
mine. No RF sensing.  You just short the wires together and it will key 
the amp.  Works fine with the FT-817 & looks like it will with the 
Argonaut VI, with proper plug, but might not with the KX3.  I believe 
the KX3 has a max of 5 volts, but may be wrong.

As with a lot of stuff from China, no instructions.
