RFI hunting.

I have been doing some RFI hunting today, in order to find some of the noisy switch-mode power supplies in the appartment.

I found a rather noisy one (cheap "universal" laptop supply) with wideband "carriers" every 70 kHz and the noise level dropped considerably when that one was disconnected.

I have been considering replacing as many as possible of the switch-mode PS's with linear regulated ones, because it is far too noisy here, Maybe not worth it, since some neighbours probably have some noisy ones as well.

In any case I am enjoying the little bit more quiet environment here.

It is far from over yet, but a good beginning.
