My ion-exchange resin water softener needs replacing. I am thinking of
trying one of the electronic systems, but wonder if there are any LF QRM
concerns (and how do I measure the hardness of the water)?

Don't know about LF but they throw harmonics up into all the HF bands. I've
had constant interference on 20, 15 and 10 from one thats about 500 metres
away for the last five years. It consists of a length of wire wrapped
around a copper water inlet pipe fed with an IC chopper output. How the AC
gets through a copper pipe into the water beats me but the mfr says it does
and it is then supposed to do miraculous things to the molecular structure
of the water. The dear old lady who owns it believes it works and I haven't
the heart to tell her she's wasted her money. Our water here is neutral
anyway so we don't need softeners.
