Danger of uncommanded PWR off?

Is there much danger of issues caused by just turning off its power supply rather than
doing a commanded off for a K3?

I’m looking at remotely operating an unattended k3.

Mark,

If just "pulling the plug" is what you intend, that is not a good idea.
If your K3 has been idle for a long time, you can probably get away with
it, but is not recommended.

Issuing the Power off command will allow a smooth shutdown of the K3 and
will preserve its state.
Compare it to the difference between pulling the plug on a computer as
opposed to properly shutting it down. The pulling of the plug may lose
some of the configuration and current operational state of the K3.

Re: Danger of uncommanded PWR off?

Thanks Don,

I was especially worried about the very gradual drop of voltage as the unpowered
power supply’s caps discharge. I guess in the long run I’ll need to come up with a way
to command the rig off. The computer will have a commanded power off via the UPS.

I use two techniques to turn off my remote setup.

1 - I run Win4K3 on the remote computer to control some of the
adjustments. It has an option to both turn off the radio and close down
the program at once.

2 - The Elecraft Utility app has a command function and is an easy way to
turn off the radio remotely whilst saving current settings. Commands are
in the Programmers Reference Manual online.

Thanks Bill,

I’d not thought of using the Elecraft Utility. That’ll work for me....
