K2 - Info 232

Peder Haugaard-Pedersen
Hello there

Name here is Peder, SM0GNS.

I have now started building my K2 (s/n 7234) but have run into some
problems. I am in the process of doing the PLL calibration but I receive
the INFO 232 when having the VFO at 7.000. I need to put the VFO at 7.1
MHz before I can start the CAL PLL without the 232-error, but the
frequency does not change as it should do. According to the manual, the
VCO fq should decrease through a range of 10-13 kHz. Even after about 30
minutes nothing have happend.

When measuring at TP1 with my scope, I get 2.3V p-p and the fq is
11913.0 kHz at 7.0 MHz.

I have checked all components around the VCO and the three relays, and
all seems to be OK.


Anybody have any clue on how to proceed?


Best regards
Peder, SM0GNS

K2 PS-1229 Battery???

Nidge_(G0NIG)
Hi All

I recentley aquired a complete battery kit for the K2 off of Ebay.
The kit had been purchased by the seller but never built and came
complete with the Powersonic PS-1229 battery.

Now here's the rub.  The battery must have been sat for sometime
and now refuses to charge.  After 16hrs of charge the PD across the
terminals is 10.5Volt and when the K2 is switched on the terminal
voltage drops to about 3.5Volt.  I have charged it from a PSU supplying
14.1Volt.

I'm trying to find a supplier in the UK as I expect shipping from Elecraft
direct will be a bit high, my order last week for a speaker and some screws
notched up a  whopping $28 shipping bill. The likes of RS have it listed but
discontinued and I expect Powersonic UK will only be interested in multiple
orders, I have emailed them anyway.

I know that there are cheaper Yuasa NP2.1-12 (2.1Ah) batteries but these
are apparently spec'd for standby use for Alarm units and such, other than
that
the largest capacity I can find is 2.3Ah. Would the 0.6Ah difference make
a difference??

If anyone in the UK uses their K2 with an internal battery what would
your recommendations be.

Regards

Re: K2 PS-1229 Battery???

Nidge,

I don't have the K2 anymore, but still have the battery.  It's a Yuasa
NP2.3-12, and, as you say, it's really intended for standby use.  I had a
long chat with a fellow from the UK company I bought it from (sorry, I
can't remember the details), and he told me that he was using the same
battery in a relatively deep cycle application with no ill effects on
storage capacity.  And that indeed, is what I have found here.  That's not
to say that a battery designed for deep cycle applications wouldn't be
better, but at what price?  My SLA here has been hit hard on many occasions
and is still working well after 3 years of use.  Obviously if you compare
it with a battery of a greater capacity, then it won't last quite so long.
 I suppose it just depends upon how critical  it is that you don't run out
of juice.

In reply to this post by Nidge_(G0NIG)
Nidge - I have recently bought a Power-Sonic PS1221 12V 2.1Ah battery
from www.battery-force.co.uk  It is physically the same size as the
PS1229 but of lower Ah.  It works perfectly in my K2. It will cost you
15.44 including vat and P&P.

Re: K2 PS-1229 Battery???

Nidge_(G0NIG)
Hi David and Stephen

Thanks very much for the replies to my enquiry and I've followed the advice
from both of you and got a slightly lower capacity battery (2.3Ah) from an
Ebay trade for just under 9GBP+postage (total 13.45GBP)

I did get a reply from Powersonic UK who pointed me to one of their
distributors but they could only supply the 2.1Ah option.

The replacement should arrive tomorrow all being well.

Again thanks both.

Regards

Nidge (G0NIG)
