Hi Ron,

You can use the XVx OFS menu entry to enter an offset of +/- 9.99 kHz
for each transverter band.

Hi all,


I know, I know... I should have used a trickle charger on my K2's battery
like the one Don, W3FPR talks about at:  http://w3fpr.qrpradio.com/index.htm 
. But I didn't.  Before I take the easy way out and order a new battery from
Elecraft (only 30 bucks, so that's not too bad), does anyone have any ideas
to bring my old battery back to life?

The problem was that I went QRT for a year or so and left the battery
unattended and now it won't hold a charge.

On the bright side, I'm now building an SLA trickle charger similar to the
A&A Engineering one that Don mentions...there was a QST article on it a
while back...so that's been fun, but it's not finished yet and my battery
needs mouth to mouth...

Any ideas would be appreciated.

Thanks,
Tom

Tom,

Sorry, but there is no good cure for your exhausted SLA battery.  They
do have a limited lifetime, but if left discharged for a significant
length of time, there is no bringing them back.  I would guess that your
efforts to bring it back to life would cost you more time and energy
than the cost of a new battery - but then each has his own criteria for
the worth of his time - YMMV.

Hello Tom,

I know I be late but hope not too late.

Maybe your battery has a chance, but without guarantee. You say the battery don't hold the
charge. So my question. Is there a significant charge current (minimum 100 mA) over some
hours, if you put the SLA on 13.8 volts? If you now say "yes", put the SLA in the garbage,
like also Don sayed. But if you say "no", it's possible to bring the SLA back to life.

In this case it's looks like the battery has a sulfat layer on the lead packages. This
caused in a high internal resistance. You can measure after a charge 12 volt to 13.8 volts
with a DMM, but the batterie don't hold the charge. The reason for it is, that the battery
has not sucked any significant current during the charge process.

So try the following procedure: Put the SLA on a charger, which gives 13.8 volts AND a
which has a current limiter of 100 mA or 200 mA or so. For controlling put a ampere meter
in row with the battery. You will see for days or sometimes for 1 or 2 weeks no
significant current flow. But if the sulfate layer at last is broken, the current flow
jumps up. You know now, why the charger needs a limiter. After the charge procedure is
solved, discharge the SLA again controlled until 10.5 volts and repeat the charge process
with normal conditions.

I repeat it: There is no guarantee, but hope.
