I concur Roy; something has changed again in the way mic gain is handled with this firmware iteration. Prior to 4.14, I had to leave mic gain set to 4 or 5 and bias to low. Those settings gave me 5-7 bars ALC on normal voice peaks. This is with the MH2 hand mic. After 4.18, I noticed that I had to turn mic gain up to 15 in order to achieve the same results. Now with 4.21, mic gain has to be reduced to 5 in order to keep the ALC happy.
One thing that I'm not sure about however is the difference in setting required for SSB and FM. When testing using FM, I have to increase mic gain by 50% to see a similar ALC readout. I don't remember if it behaved as such prior to 4.14. Can anyone pse confirm? 73 de James K2QI On Sat, Nov 13, 2010 at 10:20 AM, Roy Morris <w4...@carolina.rr.com> wrote: > The 4.21 firmware seems to have normalized the mic gain setting.
