Very true
Some years ago I had an intruder alarm installed in my Clinic which is where
my station was based at the time.
Unfortunately, every time I went onto 80 metres, the alarm was tripped.
The answer was to put a key switch into the sounder circuit.
I understand that this cannot be done with more modern systems as they
auto-check even the sounder now.
My current RFI issue (having moved to the coast and sort of retired) is that
my 24 port computer network is causing an S4 on most HF bands.

Steve,
I doubt you'll be able to answer that question until the units are
installed. RFI is such a tricky thing to predict, and equally tricky to get
rid of. I suppose you could take the brute force approach of putting
torroids on any and all control lines going into and out of the house, but
even then you could still have trouble if a stray signal gets into some
piece of electronics in the system.
