K3 just goes off

k0wa@swbell.net

This has not happened to me before....

Running some FD here on CW for about an hour in an AC room  

PA 35C FP 31C

The rig just went off.  Dead.  Power supply is ON.  Pressed the power
button....comes back on.

Anyone see this before....I have not.

 In our day and age it seems that Common Sense is in short supply.  If you don't
have any Common Sense - get some Common Sense and use it.  If you can't find any
Common Sense, ask for help from somebody who has some Common Sense.  Is Common
Sense divine?

Common Sense is the image of the Creator expressing revealed truth in my mind.

Re: K3 just goes off

Is the power supply voltage dropping too low(below the threshold)?

Any chance that the adjustable current limit (if you have that) on your
power supply is set a bit too low?

Well, the PS is a switcher...Astron ss-30.

The voltage on the rig shows about 12.8 on Xmit with about 18.75 amps  Nothing
is hot.  Wires.  Connectors.  Rig.  PS.  I am a little perturbed at the voltage
drop on the ps.  I would thing it would not drop that far, but I am not sure how
accurate the meter in the K3 really is.

Has not done it again.  Never has it done it before either.

Re: K3 just goes off

Kevin Stover
Hook a DMM up to the power pole connectors on the rig and do the
load/no-load test to double chack the K3 numbers. Check the load/no-
load voltage at the power supply as well.

In reply to this post by k0wa@swbell.net
I have had similar problems which ended up being poor connections from the
power supply, where crimped connections, like on the power poles are not
making good contact.  Now I solder all DC connections from power supply, if
possible.  Also, these poor connections lower the power/amps making it to
the rig, causing strange problems.  Good luck 73

Recently, I built a new power cable...a shorter cable with automotive spade
fuses.  The Radio Shack Spade Fuse Holders are defective.  Would not seat the
fuse properly.  Thus, the connection malfunctioned.  I will be replacing those
soon.

Re: K3 just goes off - SOLVED

Glad you found it Lee!

Many problems similar to this are caused by a bad crimp job on the
Anderson connectors.  I would encourage everyone to get the more
expensive crimp tools with the right dies for the various amperage
connectors used.

Soldering is fine too but not needed if the cable is crimped properly.

In reply to this post by w0mu
I am not a fan of Powerpole connectors, but use them for compatibility to
other ham gear.  I think they're better than Molex (as an example) but they
are not mechanically secure enough (no locking tab) without adding an
external piece (I tape the crap out of the attached connectors).

 

For high current items (greater than a few amps), I crimp with the proper
tool AND solder (pre-tinning the wire).  One is a mechanical connection, the
other is electrical; either should work; together is insurance.

 

No I don't wear a belt and suspenders (are they still available?); but try
to beat Murphy at his own game every chance I get.  If I EVER get my hands
on him...  :o)

Absolutely. I bought a power cable from West Mountain and one of the leads (the red one) just fell out of the crimp connector. So much for trusting the "professional".
I do all of my crimps now and do not solder any. I use the best crimp tool.

A properly done crimp is better electrically than solder. For one thing, solder is not a very good conductor. A proper crimp is actually a weld joining the wire to the terminal.

Re: K3 just goes off - SOLVED

What does the maritime industry use? Anyone work at Boeing who can tell
me why they (I think) crimp instead of solder? I thought I remembered
that it's because crimps are stronger over the long-term under
vibration. I could be making it all up.

I'm just curious if there's a reason or if people are just talking for
the sake of talking. I've had lots more solder joints fail than crimps,
but I've had crimps fail too.

Re: K3 just goes off - SOLVED

You've hit on why the auto industry uses crimp also (probably because of cost as much as anything too). When a wire is soldered, a bit of the solder tins up the wire strands and vibration or flexing can quickly cause the wire to break and negate the reason we use stranded wire in the first place.

Re: K3 just goes off - SOLVED

In reply to this post by Hisashi T Fujinaka
Crimps are good if they are properly done with proper sized terminals
and proper crimping tools for that type and size of terminal - there is
no "one size fits all" crimping tool, and I believe there lies the
problem with amateurs using crimped terminals - buying the proper
crimping tool for each and every crimp terminal would be prohibitively
expensive.

Yes, there are consumer grade "universal"crimping tools and terminals,
but they grip the wire over only a short distance - professional crimps
will make solid contact with the wire over a larger area, and will be a
gas-tight connection where corrosion cannot get in.

I believe soldering is a better alternative for amateur work. Soldering
does have one disadvantage and that is solder will be wicked up the
stranded wire for a small distance, AND if the wire is subject to
vibration at that point, the wire will eventually break right where the
wicked solder ends (under the insulation where that break cannot be
immediately noticed).  So in high vibration environments such as
avionics, soldering is a definite "no-no", but at the home station
installation where the wires are seldom moved, soldering should be just
as good or better than properly crimped terminals.  In your mobile
installations, you might want to consider either crimping or supporting
the wire for about 3 inches away from the soldered terminal.

CW Key suggestions ?

Ronald Nutter
In reply to this post by Hisashi T Fujinaka
Thanks to all that have responded to my previous questions.

The next thing I am looking at is getting a CW key.  I am thinking about
getting the "plug-in" key that is an option for KX3.  Since the KX3 that
I have ordered probably wont be in my hands until sometime around
Christmas based on the other emails I see of order date to ship date, I
am looking at getting a CW key for the FT817 I will be using in the
interim.

I am thinking about possibly getting two different keys - a straight
key, possibly a Nye-Viking type and maybe something similar to the
Iambic keyer paddle as my cw skills improve.  While I probably wont do
CW all of the time, it doesnt hurt to be more fluent in that mode than I
currently am.

Would appreciate any suggestions in this area that anyone here has.

Thanks,
Ron

I agree about the inexpensive crimping tools...possibly not about prohibitively expensive. A small array of adequate crimping tools can cost several hundred dollars which I don't think is too much when you consider the money spent on just one high end transceiver. I think those flat plate crimpers you see in the automotive department at the hardware store ought to be outlawed from the hamshack.

Ron,

I use a Bencher BY-1 that I bought used on eBay.  I don't do too much
CW, so it was a great purchase for me.  It's inexpensive, solidly built,
and the foundation level key from one of the top names in CW paddles, if
you don't want to pay for a Vibroplex.

Hope this helps.

73,

Re: CW Key suggestions ?

In reply to this post by Ronald Nutter
Ron,

For paddles, the Hex Key from Elecraft is always a good choice - it is
about half the cost of premium paddles from N3ZN or Bengali (use Google).

I recently acquired a single lever paddle from Tony N3ZN and can tell
you it is a work of art and extremely smooth operating.

For straight keys, check out the popular auction sites for J-38 key, or
look at the N3ZN straight keys (not yet priced) at
http://www.n3znkeys.com/c/7/straight-keys-coming-soon.

Nostalgia fever has driven the price of the J-38 key up considerably.  
Back in the '50s when I was a new ham, they were available for $1 or $2
- but then you could also buy an ARC-5 transmitter or receiver for $5 -
we generally stripped those for parts to use in other homebrew projects,
but some remain intact and are selling for high prices if they are still
in good original condition.

73,
Don W3FPR

And if one uses silver based solder?

Nope I don't and won't until I need to resupply; which will be quite a while from now.
