[Elecraft] K3/0-Mini - Experiences?

[G4GNX]

Fortunately these devices are not mandated in the UK.

Whilst the prevention of fires is laudable, ISTM that the regulators have
jumped the gun and insisted on the use of a device that is still under
development.

Reading the WIKI on AFCI breakers, where lightning nuisance trips occur,
they are under-developed "devices of the devil"!

Perhaps it's time that litigation took place, along the lines of: "It was
late at night and there was an electrical storm which caused an AFCI to
trip, which resulted in the lights failing. My aging mother fell down the
stairs in the dark and broke her collar bone, for which I hold you fully
responsible"!!!

It would seem that it is still not possible to fix 'stupid'!

I recall reading something in an ARRL publication or newsletter that at
least one manufacturer of AFCI breakers has addressed and corrected the
problem of RF susceptibility.  That company is Eaton.

It is a bummer that consumers must suffer from products that do not have
sufficient RF immunity.  If all manufacturers would 'step up to the
plate' and accept that we live in a world where RF is present, often in
strong fields, we would not have a problem.  Hams are not the only cause
of RF problems - think of the problems encountered by those who reside
near broadcast stations.  RF fields are emitted by police, fire and
other emergency service transmitters.
IMHO, more manufacturers must be willing to design products that can
withstand reasonable RF fields.  Of course, most consumers do not
understand that, and the ham "is to blame".  There was a parallel back
in the 1950s and 1960s with television interference when many TVs were
designed with front ends and IF chains that would pick up RF on most any
frequency, much to the consumer's dismay and blame placed on the ham,
even if his transmissions were clean of harmonics.
It just about drove operation on 15 meters off the air because many TV
sets used a 21 MHz IF that was 'wide open' for interference.
