My apologies if this has been answered previously.
I just bought my first PSR-500 at Hamvention, and noticed yesterday that there is a constant hiss from the speaker while scanning. From my days of working on stereos, it sounds like part of keeping theAF amp transistors biased. (The hiss is only discernible when using the radio in quiet areas.)
Is this a common issue with the 500s? Maybe something that only shows with scanning certain types of systems?
Thanks in advance.
