[FARC] David and tuner

[ROLAN.CLARK at comcast.net]

David, 



Also remember that without transmitting you can tune the antenna tuner for maximum rx noise and with a little practice you can get so you will be very close to a match when you have the highest level of rx noise, not necessarily signals but good  ol' atmospheric noise. I read the manual again and looked at the schematic and I feel certain that it is designed for high Z   end fed 1/2 length antennas and probably a  'normal' dipole or vertical won't tune at all. 



I didn't see where it said in the manual what indication to tune for but it looks like in the tune position when the bridge consisting of the input circuits for three legs of  a bridge  and the antenna tuner making up the other 4th leg of the bridge that  you would tune for min or no LED indication. 



Looks like a neat setup.  I like HI Z input antennas because I believe gnd losses are minimized and the counter poise lead reduces  hand/body capacitive effects. 



I hope this helps,
