I wondered what filter bandwidth settings you had. A narrow bw of course
reduces the noise getting to our ears. How did you handle cw and ssb in
that respect?

The N0SS demo is very impressive. The noise sounds like what I have here
in
the city suburbs most (all) of the time. But here hitting "NB" has no
tangible effect. I have not found it useful ! (OK; I probably need to
read
the manual and play with the settings.)
On the other hand, "NR" does work well provided the wanted signal is
strong
enough. (Once again, read the manual, I know ...)
On 80m I have now adopted a different approach to the awful local noise
levels. I found that hitting "ATT" was very effective in reducing unwanted
noise, especially when listening to weaker signals, including VP6DX over
8000
miles away and nothing like as loud in here as on the N0SS recordings.
Today I tried listening to VP6DX on 80 with ATT set to OFF and the noise
was
painful. Hitting PRE made it far worse. NR did not really help, but with
ATT
ON, I worked them on 80m CW with just 10w ....
The antenna here is a 20m wire bisquare, bottom corner about 7 feet off
the
ground and firing vertically upwards on 80.
As the VP6 op said when I told him .... "OUCH"
But the mojo sure works, because I also made it on 80 with 100w of SSB !
Again this was with ATT ON. PRE seems best left for the HF bands, 20m and
up. But ATT is a powerful option when all else fails.
