Welcome to PA0SIM´s home page
Dedicated to Ham Radio
My main interest is CW on short-wave, but thanks to the companies that don’t know how to design for EMC, my next interest is reducing QRM.
So you will find on these pages mainly my ideas, experiences and results on local and non-local QRM/noise reduction.
Some examples of what can be found on this site:
Some audio samples:
If you do not like noise and/or you think your IC-7700 has good noise reduction, you should try the highly effective audio noise reduction software (.ZIP file) available at the end of the Software page (last update: August, 2014).
This 40mtr SSB_example gives an impression of the noise reduction.
I don’t have a lot of acres for antennas. Having a small city lot and too many neighbours makes the chance of local QRM very real. Not all sources can be tackled and you have to live with these remaining sources.
You have neighbours and no local QRM? Then you are (still) very lucky.
By the way:
The level of civilization is inversely proportional to the noise level (any noise: acoustic, electromagnetic or light).
Maybe that's why SETI has heard nothing yet.

(PixScreen Lite) gives the best results.
