Thanks... My audio sounds kinda tinny with the audio into the microphone input on a Motorola M110... 

Look elsewhere I will....

It is one of those 'it really has no good reason to ever be used' options, and I have no idea why someone wanted it,
but it was harmless and utterly trivial to add, so I did. It, along with a few others of those were never documented
to discourage their (quite questionable) use.

So if this setting txprelim=no   is: 

TX audio processing. Options: (no,yes). Choosing yes turns on transmitter
preemphasis and peak limiting, along with a lowpass filter. The yes option
is used when driving an FM transmitter directly by injecting audio right into
the modulator. The no option provides audio which should be injected into
the microphone input of the transmitter or at some point in the transmitter'
speech amplifier before preemphasis,
and limiting.

What is the setting? 

Nothing in the manual about it.

Thanks 73
