0 BoxCar Posted June 10, 2023 Report Share Posted June 10, 2023 There is always static on any radio frequency. You set squelch to raise the receive threshold so any stronger signal will open the receiver to listen. Monitor disables the squelch setting.

0 Guest Posted June 10, 2023 Report Share Posted June 10, 2023 As @BoxCar mentioned: There is a certain noise level on all frequencies of the radio spectrum. (Static and weak signals and interference and ... just noise) In order to not "go crazy" listening to this all day long, radios use squelch to mute the receiving end unless a strong signal is received. Once a strong signal hits the radio, the squelch opens and you can hear the incoming transmission. The assumption is that the difference between the noise and the signal is large enough so that the squelch can do its job. Sometimes, you might want to see if your squelch is set to high and you are missing a transmission. The monitor button is fully opening the squelch and you can listen to the general noise and weak signals. If you are using a receiving code (a tone that opens the squelch), it might be courteous to take a quick "look" if the frequency is clear before using it by opening the squelch (press monitor).

0 nokones Posted June 10, 2023 Report Share Posted June 10, 2023 It would have been nice if Wouxun made the "Monitor" feature to disable the CTCSS decode instead of blowing squelch. Also, adding a "Talk Around" feature would be a great feature for the radio. Quote Link to comment Share on other sites More sharing options...
0 WRWE456 Posted June 10, 2023 Report Share Posted June 10, 2023 The monitor is just a shortcut to zero squelch without having to mess with your squelch setting. Your radio is working properly. WRUU653, SteveShannon and OffRoaderX 3 Quote Link to comment Share on other sites More sharing options...

Your radio is working properly. Correct; pressing the MONI button simply allows you to monitor everything on that frequency, regardless of squelch level, tone squelch, or even time slot or color code for DMR.

0 WRUI365 Posted June 11, 2023 Report Share Posted June 11, 2023 Actually monitor for digital transmissions work differently then they do on analog transmissions. You don't have a squelch noise floor on digital like you do on analog, because digital is only sending data/1's and 0's. So when you hit monitor on say like my XPR7550E/XPR5550E in dmr mode, you just turning on both time slots and all color codes to hear what is on the frequency. You won't hear any static.

0 Radioguy7268 Posted June 11, 2023 Report Share Posted June 11, 2023 To be clear, Motorola XPR radios do not have a "promiscuous" mode to listen in to DMR timeslot activity without regard to color code or timeslot. You can listen in analog mode, and then when you press monitor, you hear all activity on the frequency - but listening to encoded DMR digital in analog carrier mode is akin to listening to a buzzsaw. It is not pleasant, and it's not going to give you decoded voice on an XPR. Quote Link to comment Share on other sites More sharing options...
0 WRUI365 Posted June 11, 2023 Report Share Posted June 11, 2023 Not in the sense you speaking of. And 2 not listening to digital traffic thru analog frequencies either. Quote Link to comment Share on other sites More sharing options...
