[K3] Internal clock delay

[Petr, OK1RP/M0SIS]

Hi,

sorry for stupid question.

The internal clock seems to delaying for couple of mins during few months on
my K3 (built mid 2008).

Does it means that an internal battery cell life in my K3 is ending?

Thanks,

Petr,

Those "coin cell" batteries last a very long time, the current drain is
very low.

A couple minutes over a "few months" is also rather tight tolerance for
the internal clock.  Even a computer clock can be expected to drift some
unless sync'ed with a time standard regularly.  The K3 clock is a
similar design.  It is not a precision long term timepiece like a watch.

So, I have to ask - did you ever observe it over several months some
time ago?  If so, did it have better stability then?

If you do not have the subRX in your K3, it is easy to change the
battery, so why not just change it for your peace of mind.

OTOH, if you do have the subRX and/or the K144XV, I would suggest
monitoring it for several months before deciding to change it.

Hi Bill and others,

many thanks for all responses.
Well my K3 is fully loaded so there is not so much empty space inside :)
But yes, as Bill suggested I will plan to replace it during the xmas holiday this year probably.

I did not noticed the delay of the cockpit time in the past so it seems like cell is dying maybe.
I still have the 1kHz roofing filters on the shelf waiting for installation so maybe it is the right
time to kill two birds with one stone...

best regards,
Petr, OK1RP
