Hello All

I am new to the list

Have just started building my K2 Eric. Can't promise to screw it up but
no doubt I will call for help sometime.

One question. Just assembled the control board & carried out the
resistance checks. I did not find any shorts but some of the resistance
values did not match the figures given. I realise it will be tested
later but the instructions made no mention of what to check if the
resistances were not as specified.

Welcome Dave,

Not been here too long myself, but you will meet a lot of super and very
helpful folk who go a bit daft when CERTAIN subjects are discussed!! I don't
have enough experience with the K2 to answer your question  but I'm sure
that you will receive informed answers.

Enjoy your K2 beastie.

73,
Geoff

Dave,

Welcome to the list.

I am not certain what you mean by "did not match", and in this instance the
meaning is quite important.

There are 3 resistance ranges shown in the chart - yes, your readings should
fall within that range, if not, try reversing your meter probes, using a
different meter, check with a fixed range instead of auto-ranging, and if
that doesn't resolve the issue, check your work closely for proper value
components, shorts, etc.

All the remaining resistance readings are of the "greater than" variety
(that is what the ">" symbol indicates).  If you obtained a reading higher
than that indicated, all is well, but if your reading was lower, start
looking for the error - component values, soldering, etc. -- note that if
your readings were just a tad lower, it may be nothing more than difference
in your meter compared to the ones used to create the chart.

Don W3FPR

Such a promise is not necessary, David. Hi. Welcome to the list. I hope you
have an enjoyable building experience. I KNOW you will have many enjoyable
operating experiences. The K2 is a great rig, and I certainly don't see
anything on the horizon I would trade mine for. I'm STILL trying to dump the
TS-950S that the K2 replaced, but no takers yet.

But if you DO have a problem or a question, you won't find a nicer or more
knowledgeable bunch of experts to help than right here.
