[ICOM] Mic gain on the 706 MKIIG

[James E Good]

For whatever it might be worth:

The settings in my '706 MK II G are as follows:
Menu selection Q2     Mic Gain        5
Menu selection Q3     VOX Delay    1.0
Menu selection Q4     VOX Gain      5
Menu selection  Q5    ANTI VOX    10

The small pots on the right side of the radio are both at aprox. the 10:00 
o'clock position when facing the pot.  These settings are used on both HF 
(mostly 80 through 10 meters) and 6 meters into an inverted V hung in trees 
and for VHF/UHF fed into an MFJ dual-band base antenna.  The feed point on 
the HF antenna is more than 35 feet high.  The feed point for the VHF/UHF 
antenna is about 15 feet high.  All contact reports on every band used has 
been good.  I am running at reduced power on both sides of the radio (80 
watts on HF, 25 watts VHF, and 10 UHF).  The information for finding the "Q" 
series menus is in the owner's manual.  Enjoy the radio, it is a very good 
one.

73.
