Hi,
Wasn't sure where to post this, but I have an issue with our Motorola P-25 digital system that recently went on the air and I wanted to see if anyone out there has any suggestions. Our service folks say digital tones are not that great compared to analog, and they cannot come up with any solutions. So, I will ask here.
Issue- We transmit one mono tone for a few seconds from the dispatch console over the active T/G to alert fire companys of an incoming alarm. Frankly, the tone sounds terrible. It has been dubbed "we are getting a fax!!" because of the way it sounds. Very shrill and uneven in its audio quailty.
We did this same operation when we operataed in analog and the tone was much cleaner and even.
Radio service says there is no adjustment that can be made to improve the sound quality of the tone on the receiving end. With that said, I have listened to other agencys using the same P-25 equipment and their tones used to sound like ours, but now they do not. So, they had to have adjusted or changed something...
I listen to MetroSafe in Lousville, Ky and MECCA in Marion Co. both of which use Motorola P-25 digital systems and their alert tones are much cleaner and even than ours.
Anyone have any suggestions on what we can try?
Thanks very much.
