Re: UV-25... Need some help
|
I have had a couple of Baofengs which were plenty sensitive, in that they hear the FM satellites as well as any other radio I have had.
In any model there will be some failures. But that doesn't mean the whole line is bad

Hello Ricky,
Baofengs since they are built to a price (low price) do not perform like others in the marketplace. You get what you pay for. It is well known that Baofengs are unsensitive, unselective and their transmitters are dirty as their harmonics are way too high.
Because of this, they are totally banned in some countries and here in Australia, amateurs are the only people who are allowed to use them, since we are allowed to design and build our own radios.
If you want a radio that should perform to spec, spend a few more dollars and buy a more reputable brand.
Greetings;
?
I bought a UV-25 from an Ebay store, and the radios receiver was Insensitive, it receives poorly.? ?
?
After complaining, the Ebay seller sent me another radio.? ?It turns out that both radios receivers are insensitive.??
?
Using a TinyVNA's signal generator, through a switched step attenuator, the full quieting receive level is approximately -90dBm on 146, 440 MHz + WX channels.? ? This level equates to approx. 6uV, or S6.? ? ?VNA's signal generator sends a quiet carrier,
no modulation.
?
Using the same testing method on my other handy talkies, I achieve full quieting at -115 to -120 dBm.? ? ? ? ? Note:? I used my Rigol Spec Analyzer to verify that my test signals are accurate +/- 1dB.??
?
Searching Google and Youtube for help- I find Zilch.? ?Could there an option that I don't understand the meaning of that could be set wrong?? ? ?Any help is much appreciated.
?
Thanks in Advance.
