what i need is  dtmf  aka  touch tone.  this is in the audible range ancd the uv5r will generate  it for control purposes.  it is momentary aka touch tone.
the system you are describing is a continous tone in the 100 hz range and is filtered out  of the receive audio.


thanks for reply

HI Jim
I see where you are saying dtmf, but I wonder if you are talking of CCTCS
n both TX and RX. On ham rigs you can have a tone squelch for receive and
ne on TX also a choice, on RX it is used so the receiver only receives the
esired repeater, on TX so you only get into the desired repeater in highly
ense repeaters. But my bet it could be used as a security measure. When it
s used for both it usually is called Tone Squelch or shortened to TSQL I
ave that on my VX5R for some repeaters which tells the rig to look for the
one on receive and open the rx and to tx the tone so the desired rx 
pens to
eceive the signal.
his may not be what you are talking about but you mentioned not seeing it
n the layout for the rig you are using but is there a field for TSQL?

 thanks.  would appreciate any help possible.  with the advent of 
 narrow banding, all our pagers will not work.  we are paged out by the 
 sheriffs department over a public government channel using the dtmf 
 codes.  have already explored their sending either a different pl 
 tone, or a dcs signal, but their system is not capable
 of doing either.  for the price of a handfull of pagers, could equip 
 the entire department with these units, and gain a talk around radio.
 not sure what an Arduino sketch is

 Not implemented on the radio firmware. I have an Arduino sketch that 
 may help, I'll send it tomorrow

     i have need to use this radio as an alert pager for local vol.
     fire dept.  see where to enable dtmf on transmit, but no 
     capability to do so on receive.  is this possible, and/or am i
     missing something in the programming.
     basically need to receive only one tone.
     thanks for help.   jim  kf8sj
