Just spoke to APC, they seem to no longer make filters! Only UPS units as per they support desk... Any suggestions on a good AC power filter for CMC?

Hi,

How well does that APC filter work?  In human terms, no need to go into db unless you have those numbers, and what is the model number of the filter you use please?

I tested mine with a SW RX, sprays RFI all over 80 meters... Luckily my antenna is 60 feet from anything, so I don't pick anything up.  I will drag down the Spectrum Analyzer and post a shot of what it does in the next week...

These coffee makers are noise generators. Mister Carlson's lab had a Youtube video on how to troubleshoot the coffeemaker and how to add safety filter capacitors to attenuate the noise:

I am not a coffee drinker. I make a cup in the morning using instant coffee and it lasts the whole day, sometimes into the next morning.
