Re: [Elecraft] New KSYN3a installed and not working / recognized

[Michael via Elecraft]

My KREF3 board needed R12 to be changed from 150 to 51 Ohms, even though I  
only have the K144XV option and not also the sub receiver.
 
Problem fixed!

Re: [Elecraft] New KSYN3a installed and not working / recognized

Any chance that my K3 needs the KREF3 Output Level Modification to increase 
 drive to the KSYN3a?
 
I asked for this kit and have it on hand

When it's right, there won't be even 1/16 inch between the wings and the

You should probably check that the REF IN cable isn't shorted or open.

Re: [Elecraft] New KSYN3a installed and not working / recognized

[Ron D'Eau Claire]

Hi, Michael. 

Do you have firmware 5.14 or later installed in the K3? The current
production release is 5.50 which is the recommended firmware at this point. 

If your firmware is okay, be sure the board is correctly aligned in the
socket on the RF board so all the "pins" are engaged. 

Presumably it all works with the old KSYN3 board in place? IF so, then all
that's left is a bad board...

[Elecraft] W2 wattmeter lock-up

[JOE]

I had a situation where the W2 watt meter would flash the LEDs on power 
up, then I was not able to communicate with it via the RS232 cable.  
After repeated attempts, I was able to quickly press the LED on/off 
button on the software during power up to make it come back to life.  I 
had to press this button during the power up cycle or the W2 would not 
respond.  Evidently the LED button got pushed by accident, but it put 
the W2 in an inoperable mode that required a site visit to our remote 
base location.


Has anyone else experienced this?  Probably most people never use this 
feature.

Re: [Elecraft] Cold K3

[N2TK, Tony]

Hi Ed,
We routinely test military/space parts at -55C to +125C. The parts are under
voltage and monitored throughout the range. Many of the failures at the very
low temp ranges may not be permanent. As the temp is raised the device most
of the time functions properly again. There are some anomalies though. We
have seen some memory devices work fine at -55C and then lose bits around
-40C. And then work fine as the temp rises again.
At the high temp end there is greater chance for permanent failure.

So, very cold temps can be an issue with any of our gear, especially
considering we are using commercial parts. 
Test temp ranges for semiconductors;
Commercial - 0C to +70/80C
Automotive - -40C to +125C
Military - -55C to +125C

N2TK, Tony

Subject: Re: [Elecraft] Cold K3

Dick,

The KX3 will not see those extreme cold temps.  Where we live it rarely
drops below -15F and typically is 0 to +10F at night in winter.  The KX3 has
a RAM bracket in my truck so it might sit outside at night. I was wondering
how it would react to being powered on at down to -15F.  Truthfully it might
not ever face that as I have remote start for the truck to warm up for
winter driving so the cab might reach +20 or higher before I would use it.
A few miles driving and the cab should be +50 to 60F which is comfortable
wearing a winter coat.

More than likely I would just bring the radio inside at night if planning to
use it the next day.  My experience with the TS-180S was that the cold
effected the LCD screen so operating was not possible until it warmed.

That experience in 1986 was the coldest I have seen in my 36 years up here
in AK.  Quite possible the temp dropped to -80F at night (-78F is the
official record for AK).  Fortunately at extreme cold the air is completely
calm most of the time.  Dog teams coming into the checkpoint reported -45F
on the ridge tops but with 30-40mph winds which would feel much colder than
what we were down in the lake valley.

The coldest I have experience at home on the Kenai Peninsula is -35F and
that was nighttime so I stayed inside near the wood stove.  I now live in a
modern home with force-air natural gas heat and its +67F to 
+71F year round.

Radio gear is std in all vehicles used at Prudhoe Bay on AK's "north slope"
but either they leave the engines run continuously or they are plugged in
with electric heaters on the inside keeping the interior from freezing.
Ever climb into a suburban when the seats are -40F and hard as a rock (a
very cold rock)?  In fact the seats split apart if allowed to get that cold.

Most repeaters up there are enclosed in warmed buildings and only antenna
and coax outside.

I had fun up there in Nov.1980 installing MOT radios in heavy equipment that
was parked outside (it was only -15F so my bare hands took a punishment).
After a couple days one of the operators showed me how to start up the
engines and I got a little warmth inside the cabs (+15 vs -15).

I was young (36) and adventurous - making $6500 in three weeks working
18-hour days didn't hurt, either.

I've not tried running my K3 at outside temps,

Hello Ed,

I would caution you against trying your K3 in those temps.  Minus 60 degrees
F. is the coldest on record for Minnesota, and you experience far colder
that that. The cold may do multiple things to the K3 if it has multi-layer
circuit boards.  I didn't notice if it does.

Our club left a repeater in an unheated enclosure one winter. I would
estimate it wasn't much colder than minus 30 degrees F. at that location.
(To clarify for others, this is 30 degrees F. below zero.)  I have seen what
the multi-layer circuit board looked like. More specifically, the
thru-the-hole solder connections from one layer to another were cracked.
Maybe it was the type of solder used???

I'm sure circuit designs have changed since the first solid state rigs I
described in the cold.  LCD screens hadn't been heard of yet.  I'm surprised
they don't freeze and get damaged in your temps.  It is interesting to read
of your outdoor experiences.
