[chirp_users] chirp_users Digest, Vol 53, Issue 29

[nanojects at verizon.net]

 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
