Fw: K3: CTCSS means "poor" sound on FM

[Ken G Kopp]

The second paragraph should read "The CTCSS TX deviation".
The voice deviation is normally set to about 4.5 or 5 KHz.

>
> The TX deviation is set to about 600 Hz, with 750 Hz
> considered to be the maximum that should be used.
>
> CTCSS is almost a necessity on today's multi-user
> FM channels, where different user groups are stacked
> 10+ deep on channels in busy metropolitan areas.

> 73! Ken Kopp - K0PP
