The Radio Information Board

We now believe it has something to due with a static discharge. One unit now completely shuts down. After changing to a plastic mic hanger it does not have issues as much. But, still shuts down 2-3 times a day. Any Clues????? Brandon Brown Chief Deputy Armstrong County S.O. brandon.brown@co.armstron...

Found it to be a issue with the siren amp. Unplugged it and Secondary speaker now works. But unable to play it out side. The radio shop placed a transformer inline work but outside speaker pops and squeals all the time. Any ideas would be helpful.

My Ext Speaker will not work most of the time. Sometimes when high modulation signals are received like page tones, or load operators the speaker play sound. But most of the time it is silent. One unit was taken into the radio shop when the outside speaker was not working. (going through siren box)....

Has any one ran across a issue of a 53SL ES just rebooting. Mine will do it at odd times. Some when the mic is taken off the hanger. In the middle of transmitting ( note transmission completes, but unable to hear reply). Then sometimes when just going down the road. I have check all power connectors...
