The Trunking mode works fine but regular scan mode remains on single channel as squelch never cuts out static. This is true for all freq ranges and banks. Trunking works great. Squelch in reg scan mode worked fine for a few weeks
Re: squelch quit working in regular scan mode PRO-528
Just fixed my squelch problem; I don't know how it happened but Resistor 138 was burned & intermittant. It was so badly burned that I could not read the color code but it measured 880 ohms intermittantly. I replaced it with an 860 ohm carbon resistor & all seems well; time will tell. R-138 is located on the circuit board right behind the squelch potentiometer. R-139 is immediately behind the pot & R-138 is next to R-139. All I had to do is remove the 4 screws on the back of the case & the unit splits in half. I clipped the old resistor out leaving a bit of the old leads so I could solder in the new resistor without having to get to the backside of the circuit board. Scanner is working as I type this & I hope it does not burn out again. Hopefully this is the same problem in your scanner & an easy fix. Good luck.

On all channels, or on one channel ? Some channels are "birdie" channels, check your user manual. Others are problem channels receiving false signals from computers, monitors, receivers, internet equipment, FAX machines, etc. If your in conventional mode, if in Digital mode the squelch is set by the processor, and I don't believe the squelch has any effect in that mode.
Hopefully Resetting or Initializing the scanner will clear the problem and get it working again for you. Instructions for these procedures are on page 38 and 39 of the scanner operating manual. If you don't have the manual, you can download and print it, at no cost, here:
If you are using a trunking system, then it sounds like you just have it set for "FM" mode, instead of "MO" Motorola trunking. You will have to use your owners manual to see how to set up a trunking system by putting the control channel (tower) frequencies in a special mode, then it will work if it is a PRO 96, PRO 106, etc.
You have to program it TRUNKING mode when you enter the control channel frequencies. It is decoding okay as the MO shows motorola control channel and +DG means digital decoded and an OPEN group. You need to press the 'trunk' button everytime a talkgroup comes up that you want it to remember for future 'closed' group (-DG) talk groups. I suggest you go to 'RadioReference DOT com" and there are many forums there for your radio, as well as one or two YAHOO GROUPS specifically for your scanner. 73's
Did your local public service switch to a digital system? If so, you cannot receive digital trunking on this radio. Ask at your local Radio Shack store, or a local ham radio operator who can help you out.
Are you getting talkgroup ID's? If not, you're probably monitoring the EDACS system in conventional mode rather than trunking. When the scanner hears those beeps, it's supposed to go back to monitoring the control channel if you're in either trunking mode (search or scan). This also happens if the CC isn't coming in very well. If you're not in trunking mode, read the manual to find out more about programming and monitoring trunked systems. If you are in trunking mode and receiving ID's, the unit is probably malfunctioning.
Often the potentometer (squelch control) becomes worn or dirty, this can be sometimes cured by spraying a WD40 or similar oil and then rapidly moving the control down and up. Do not use oil that is conductive.
