[Icom] Mic Gain Problems with 706MKII

[Siu Johnny]

Hi Mack,

Insufficient mic gain of the stock hand mic HM103 is a typical problem for
IC706 series.  Please read icomamerica support page for Ic706.  If you do
not know the exact web link, please visit icom FAQ web page www.qsl.net/icom
or the icom section of www.mods.dk

If all the solutions given in the above web pages do not solve your problem,
you may consider getting the One Big Punch speech compressor from
www.w4rt.com

If you still have problems, please email me direct because this matter was
discussed in the past and I do not want to occupy the band width here.

Happy Holidays!!
