Author Topic: How do Kenwoods PL Work?  (Read 372 times)

I was looking at some of the new Kenwood radios.

I understand how coded squelch works, but don't understand how Kenwood
implements it. Can someone please explain to me?

They have a [T]one mode and a [CT]CSS mode.  You can only have one mode on
at a time.

I need a mode that both transmits (encodes) the tone and will not allow
reception (decodes) without the tone for a single channel.  Is this [CT]
mode?  Is [T] mode only transmitting the tone, but has open receive?

The manual is not very specific.

You pretty much described how it works.  It is a bit confusing at first.  The *T* tone selection is just a transmit subaudible tone for accessing repeaters.  The *CT* tone is a transmit and receive subaudible tone.  Some repeaters have an Rx AND Tx tone.  The *CT* is also useful for simplex with another user that has the proper tones programmed in.  Most of the radios require you to enable one of the tone functions before you can program a tone value (Hz) for that channel/freq.

Thanks for the answer.  I figured that was it, but wanted to verify it.  Kenwood manuals sometimes leave a little to be desired when it comes to details.
