:)I have an 1000mp and dont hear much annoying white noise.
If the white noise is internally generated then there is an issue, check by unplugging the antenna.
Also earlier rigs did have a bit of white noise, not much to worry about.
Only with later rigs, quieter devices were used , and I suspect front end gain was reduced, hence the silly 'S'meters on some new rigs, but they are quieter.
Center your shift and width, make sure settings are normal. Check if USB / LSB sound the same when toggling.
