[Elecraft] K3 after turning on doesn't receive or transmit

[Dave Cole (NK7Z)]

Wow, thanks for the info!

I must have missed that in the manual...  I use the power switch, but I 
had no idea there was a power down sequence for the radio.

Is it an actual power down sequence, like in triggers shutdown code to 
run, or just some timing that has to happen in the right order?

73s and thanks,
Dave

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.
