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?

Not implemented on the radio firmware. I have an Arduino sketch that may help, I'll send it tomorrow Tom Morris, KG4CYX Mad Scientist, Miami Children's Museum This message sent from a mobile device.

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
