Title: Yaesu FT-2800 Mic Gain
Post by: KB1LTG on February 07, 2005, 08:11:06 AM
Hello all,

I have a new FT-2800 that seems to have mic troubles; every sig report indicates that the microphone is overdriven and needs a tweak. The user manual offers nothing but wide/narrow deviations. Does anyone know how to adjust the microphone gain on this radio! Any suggestions or help much appreciated! Thanks to all

Jerry

I hope you find the problem!  I've heard a couple of them
locally and nobody seems to know how to turn down the mic
gain.  The resulting compressed audio is very hard to
understand.

If you find out, please do us all the favor of posting
the solution.

I'm not familiar with that exact rig, BUT--

there seems to be a tendency of some of the modern FM rigs to have a REALLY sensitive, overdriven mike,  with possibly a well hidden internal  control.

My old Icom 2350 series suffers the same fate.

The solution for it was many ohms in series with the mike element, seems to me it was either a 5k or 10k pot that I added in there.
