Eric,
On Orion II
I use the Heil #5 element in the Heil light weight boomset with these
settings and get excellent reports and works well in DX pile ups. The #5
element and boomset is about 10 years old.
I am wanting good communication audio, not Hi Fi.
MIC 50
SP3
TX EQ: -3dB
H/W MIC Gain 0.0 dB
L.F.Rolloff 150 Hz
Mic is positioned half way down towards my chin and turned at 45 degrees
towards the mouth so I am speaking across the mic face.
Others tell me that using the H/W MIC Gain worked well for them, but when I
tried it the audio drive was too much and I just leave it at zero.
