K3: Power On/Off software control?

Can the rig be turned on/off with a software command? That would make
it perfect for remote control.

Rich,

I had not seen a reply to this. Yes, there is a feature to turn the rig on
and off via the DB15 Accy port.

Thanks.

The accessory jack has a contact closure input for remote on/off, and
the internal alarm clock can wake the radio up as well.

We're looking into some sort of "wake on serial port activity" but that
is not certain at this time.

...hmmm... If it can 'wake' on serial activity it wasn't really off.
It is probably too early to know but are we talking micro-amps or 100s
of mills while in 'sleep'?

If the radio is OFF and you use the contact closure provision on the
rear panel, it is indeed OFF.

If you use the alarm function, it is sleeping and drawing current. I
don't recall the number offhand, but I think it is in the range of 50 to
300 mA.

A "wake on serial port activity" would necessarily be in a similar
range, which is part of the reason it doesn't yet -- and may not -- exist.

Re: K3: Power On/Off software control?

Lyle:

If I had a choice between the two I would go with wake on serial port
activity. I'd rather not have to come up with a way to control a relay
via remote to turn the radio on/off.

Thanks for the info.

K3 draws 3 microamps in "sleep" mode with an alarm set

Administrator

The K3 has a very versatile real-time-clock chip that runs when the rig
is off. It draws about 3 microamps as I recall. If you have an alarm
set, it will wake up the radio at the appointed time.

There's also a "standby" mode (which I think Lyle was referring to)
where everything is off but the time/date display and LCD backlight.
The alarm can also wake up the radio from this condition.

Oh, no.... You mean it's always on even when it's off? I thought we killed
that thread last week. :-)
