Re: KX3 clock & battery. (Was KX3 clock will not, set from KX3 utility)

Hi Bob.

That's not what I was asking. What I would like to know, is:-

Should the clock use External power (if present) instead of the
installed batteries (whatever their type might be) when the radio is in
the "OFF" state (i.e. Not in use.)

If I remove the cell's, then they retain their charge for many weeks
without problem. In the radio, they will drain to a low value after a
couple of weeks. Even if it is still hooked to the always on, shack DC
power system.

Is this a "Feature" or "Fault/Bug" ?

73.

PS: I have had no trouble setting the clock from the utility program,
running Windows(7) or Linux(Mint).

According to the KXBC3 manual (last two sentences of Page 2),

"Only a few microamperes of current are required to keep the clock running
when the KX3 is off. This is supplied by either the external power supply
or the internal batteries."

By this I take it that if there is a 13V power supply connected and
running, that it feeds the clock; and if not, it's fed by the batteries.
However, this might be confirmed best by Elecraft.

Re: KX3 clock & battery. (Was KX3 clock will not, set from KX3 utility)

My thoughts too, re best confirmed (or not) by Elecraft.

I've got the schematics (filed somewhere) I'll take a look later, see if
there is anything "obvious" that might be an issue.

Many thanks & 73.
