New UV5R user, no license yet, getting a lot of static, even on repeater channels. Have nice wire antenna attached to my wall by the window, and a long Nagoya NA-771. I recently discovered that, if I press the Menu button on this one channel, often it will go from static to an ongoing conversation. The conversation can go into static and I can hit Menu, and it will bring the talk back where I can hear it. What’s up with that? The Menu button is not supposed to do that, is it?
I changed Scan Resume from CON to SE. Maybe that’ll help.
I’ve heard of a similar effect, many moons ago in early PLL radio days, but not recently. On digital radios, some mind, they can (more by quirky nature than intentional design) go into monitor mode when you are in menu/settings - the obscure set I’m most recalling it happened on got me wondering too, but the cause of accidental/unexpected DM would be entirely different in nature with an analogue set.
If DW/PW is set to monitor a frequency and traffic suddenly appears there, the DW/PW monitor will shift the receiver main function to the DW/PW set frequency. Depending on radio, the radio may revert to prev frequency when traffic ceases or hold on the frequency. This often is retained irrespective of what you do menu/settings navigation if it occurs - some radios mute spkr output when you go through menus, some don’t - true dual receive rigs tend to retain Rx pass through (audio output) regardless of menu navigation and settings use.
An outside theory is that maybe, if none of the above ties in, when you go into menu, possibly the squelch gets bypassed more by quirk of design than design.
An earlier Baofeng series, UV3/UV3R had their share of unintended quirks resulting from design, just they had a busload of them - but at the time, when the radio cost less than the import costs, you lived with the quirks as the sheer value was what made you a happy user of a radio you’d never cry over losing/wrecking accidentally.
Sometimes, where radios use very basic and not always well designed ASIC logic devices, the act of pressing a switch (pulling a line to ground, where the off state is line pulled high) and subsequently changing the flow of current, was enough to cause momentary instability.
I can recall one radio where if you accidentally hit a function key it momentarily unlocked the PLL as the change of current flow was enough to disrupt the ref oscillator output. Needless to say, it wasn’t really a high point of design and it was a very failed product for that and other horrible quirks.
So I guess there can be a few, plus many I’ve not mentioned, reasons. It could be intentionally designed to do that, why is a question in it’s own right.
Beyond that, without re-exploring UV series radios (my UV3’s still function) which I’m not inclined to do, I can only speculate based on quirky radio experiences.
