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.
