I read in the very beginning of SDS200 sales there was a hum issue with the radios and Uniden was mailing people a little copper board. I read Uniden was then installing those copper boards in the new radios being shipped out. I read that people who installed these boards have had the hum return. I read one user removed screws and scraped of green coating restoring a proper ground and has not, that I have seen, had the hum return.
I would think since I got mine close to a year ago, that it has this board wedged inside. It most be oxidizing as my 200 has developed a hum. @JoeBearcat How is Uniden handling units that come in today with the hum issue? Its coming in anyway because the volume control never really felt right from day one. It definitely does not feel the same as when turning the squelch knob where you feel each position. Really not wanting to deal with a fix that does not last more than a year. I am not positive mine has that board but can say when lightly squeezing the front of the scanner, the hum gets quieter.
Also @JoeBearcat , we spoke about audio type issue a while back.
Today I was doing a custom search and landed on a P25 control channel and link/data, as well as everything else was flashing erratically with popping/crackling noise. I took the same freq and entered it conventionally three times, each with one of the three audio types. Search/All, Analog and Digital. Look what the SDS200 does when a P25 freq is entered conventionally, with audio set to Digital and nac set to search.
Notice the popping and crackling? I really do not think it should sound like that.
Also notice while set to analog, it does play the cc sound as it should when landing on a cc in conventional mode, but look how long it takes the scanner to actually release audio. Around 2 seconds ?
