From the Fred Cady manual, page 33, Chapter 3 "Elecraft recommends
that you DO NOT turn your K3s off by turning off the external power
supply. Using the POWER switch allows the K3s to store variables such
as the current VFO frequencies in EEPROM before shutting down. This
might not happen if you turn the power off at the power supply. You can
turn the power supply off after the K3s shuts down".

Yes! Like most equipment these days, the K3 needs to do an orderly
shutdown under control of its processor to turn off safely and
reliably. Like your P.C. you can pull power unexpectedly and it will
often recover okay when power is reapplied, but you can also get
corrupted data that forces a firmware reload - perhaps even using the
forced MCU load procedure in the Owner's manual - as well as
discovering that it turns on in an unexpected state or that it has
"forgotten" certain parameters you set when it was last used.

Subject: Re: [Elecraft] K3 after turning on doesn't receive or transmit
Respectfully, is that really true? The K3 needs to be shutdown via
the Power switch due to some sort of shutdown procedure, (or internal
timings issue), within the radio?
