I have the vertex vx-800 uhf firmware 1.25. I seem to have a huge problem in the squelching. When im near a computer, wireless router or cell phone my squelch opens. even if i pl set it attacks for about 15 msecs. I even set the Squelch to 7 and it still occurs. The worst part is when I have a Frequency like 462.5500 without any PL/DPL the squelch opens and start blasting near most electonic devices.

please can anyone one help me out hear? If I upgrade the firmware can it help out with this.

yes i do have PL set on RX & TX side. when near electionic devices the green light start flashing but the audio is silent. once i RX a transmission there a squelch blast at the end of each tranmissions for about 15 msecs. can you PM me with the info if you can please.

Welcome to the radio world with all the consumer electronics and their poor RF emissions control.
Your not the only one with that problem. Get use to it or stay away from all the electronics.

Even the best of radios out there get knocked by the same noise floor radiating trash electronics
today. Just about any computer bought today has the minimum effort put into them to keep
the digital noise from being radiated.

Why do you think that most of the public safety radio sites are attempted to be placed in
locations with minimum of consumer electronics near by. It doesn't take a 5th grader to
figure out that the less electronics means a quieter radio location.

Yes, Jim is pretty much right- Stay away from the computers and electronics.

Your radio shouldn't just "open up," .. or open squelch whenever it feels like... but this would be in an open area, not around buildings or businesses/ homes. The green light may flash; the radio may miss intended radio signals, but it shouldn't just make noise/static on it's own w/ PL programmed.

Now, if a radio signal was being transmitted from say, a tower site or near by source, and it had your programmed frequency/ CTCSS while you were around these devices making static and such, yes, the CTCSS decode will open, because CTCSS is a much lower frequency and travels further. This lower frequency (Hz rather then MHz) the radio will see easier, and then "open up" .. allowing the intended MHz frequency- which is now junk due to the computers/ electronics in the area- to make static.

I use CTCSS because "PL" is Motorola's "Private Line" .. same thing.. but I dislike Motorola. and I rather type extra letters then give Moto credit.
