[Elecfaft K3] Power Cycle

Everyone,
Many times by both the K3 engineers and others it has been stated to recycle the K3 power after doing a firmware upgrade. I understand the logic behind this action and do perform a power reset after doing a firmware upgrade or reload. My question is this. Every time a firmware upgrade is installed there are several apparent power resets that occur, even after the firmware install is finished. Am I correct in assuming these apparent power resets are not complete resets?

Thanks and 73
Dave KD1NA

Re: [Elecfaft K3] Power Cycle

They are complete resets, occurring after MCU, DSP1, DSP2 loads. Note
that the K3 goes through exactly the same LED test sequence and timing
is the same as a full reset. The only difference between 'normal' and
loading resets is that during loading the resets occur during power
on.

Dave,

I was really surprised to see another poster say that you should kill the power
on the K3 after installing new firmware. I have two K3's here, have never done
that and have never, ever had any trouble whatsoever with firmware
installations.

In my experience, going on 3 years, it's not necessary to restart the K3 after
firmware upgrades.

Thanks for the information. Very interesting and it fully explains why
it is important to do a power reset after a firmware upgrade.

After the firmware reset completes, what VFO setting do you see? That's the EEPROM parameter save at work. If you save and restore config, the current VFO setting us one of those settings.
