For 10 and 6 FM I use commercial Motorola Maxtrac/Radius, GE RANGR, GE Orions, Vertex FTL1011, Modified WULFSBERG RT30 and Motorola CDM1250's and I never receive a poor audio complaint for any of these commercial models as would be expected.
?
For 6/10 commercial FM Handhelds I use GE PE's, Maxon MGP300's, Motorola P200/MT1000 and recently my favorite Motorola HT is the HT1250 on 6 FM.
?
In the ham made models I use a Kenwood TS690S a Yaesu FT100D and an Elecraft K3S and for ham made Ht's i use a Yaesu VX-5R and an Azden AZ61 and all of these work very well on 6 and 10 FM repeaters and simplex without any complaints and no mods required.
?
The only complaint that I had was with the Kenwood TS690s and this was 32 years ago when I enabled the speech processor which doubles the audio in FM mode to where it is over driven so whenever using any the Kenwood ham models, Ts690S/TS450S do not turn the speech processor on, I do not see this? audio over drive issue with the Yaesu ham models? thasat I have used if the processor is on or off only with the above mentioned Kenwoods.
?
After using all of these mobile and handheld radios on, Australian, Swiss,? Canadian, New York, Texas, North Carolina, Washington, Oregon, California and Arizona 6 and 10 meter VHF Low band repeaters and numerous simplex frequencies I have never had an audio complaint on any of these? radios except for that one time with the Kenwood TS690S.
