Gary,
Many thanks for this very useful information regarding the ground pin
correction.
On the Heil #5 element on the HC-10 boomset, I have HW mic at zero, software
gain 50, SP 3, with excellent reports (that I do not ask for). The mic is
several inches away from my face between the mount and chin pointed upward
towards the mouth.
Another Orion II owner suggested I set the HW mic to 10 and it was too much
drive so it went back to zero.
I want the red ALC light to blink on and off with it more off than on or at
least 50/50 on and off.
I would guess there are as many opinions on audio mic settings as there are
hams, so this is just what works well for me in DXing.
Although it is against Heil's designs/recommendations and common opinions, I
find the #5 element works better in pile ups than the #4 element.
