Hi Linas, I can't duplicate this problem on my KX2. I would suggest re-doing the transmit gain calibration on 80 meters.
Set mic gain to about 15-20 with the MH3, or about 30-50 with the internal mic. 73, Wayne N6KR On Mar 13, 2017, at 7:14 AM, Irma Linas <irmalina...@gmail.com> wrote: > Hello group, > > I am now a proud owner of the brand new KX2 which arrived few days ago > straight from CA.
