You would use a compandor on narrow band fm with a 2.5KC deviation to bring
the audio out of the noise. You would compress the audio on transmit and
expand it on receive.  That is what it is used for in commercial narrow band
fm service.

why would you want a compandor on FM?  Narrow FM I can see but on a standard
5 KHz channel?

Subject: the new baofeng radios

I have a friend who just got one of the new baofeng handhelds. His = version
has a com pander, which is interesting. One mic feature it has, = is when
you  are in menu mode you can step through the menus and it = reads the
menus as you step through them, so you don=92t necessarily = have to know
the menu number to find a setting. This is the unit with = the more
traditional keyboard layout. i will find out which model it is = next time I
talk t him, but int he meantime, is there a list of which = baofeng radios
are and ar enot truly accessible? I have a uv5r, and = accessibility is
awesome for that one, and i am considering getting = another one in the near
future, so am at the point to choose which one I = might want, the 220
version, or the model he has.

73 and have a wonderful Christmas
