Re: [chirp_users] chirp_users Digest, Vol 53, Issue 29
Using a wideband receiver (as in the pager) to try to receive a narrow band signal ( new system) the audio will be weaker. You can try to modify the pagers to increase the audio going to the tone decode chip. Either changing a resistor or a trim pot might work to increase the audio going to the decode chip. Good luck.

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

understand what you are saying.however, these units were purchased and maintained by the one and only local two way shop. they claim that no fudging is possible with these units, and our only recourse is to buy new units, at a cost of about $150.00 per. they will not give me the details of the tone system. sounds like a simple two tone touch tone signal. the software for the radio control system comes from another source, and cannot get them to reveal anything either ALUGODUS all you gotta do is
thanks for reply
