K-Line Climate Control

I’m at the point now in my household move where I should like to put my K-Line (K3/KPA1500) out in a shed about 200’ from the house and operate it remotely via an local ethernet connection. This week I’ve been sweltering in the humid heat here in the NE and that prompts the question: What makes since in the way of keep the equipment happy across wide temperature and humidity changes? Winters possibly down below freezing, but dry, and summers up to 100F and humid. Today’s temp is clearing 88 with a dew point of 76, for example.

What do you all do, short of supplying heaters and/or air conditioners? If I could avoid that, I would like to. The good news is that environmental changes are gradual. The spec page for the KPA1500 does not seem to mention environmental specs.

Thanks for any info.

Gary W2CS

Re: K-Line Climate Control

Poor little radio - out there all alone, hot in the summer and freezing
in the winter. Alone and forgotten - waiting in the lonely darkness.
But, you expect it to do your bidding at the drop of a hat. How would
you feel if you did all your yard work in the blazing sun - then went
back to your hot damp shed?

Yeah yeah - the devil made me say it!

Is this some sort of a spoof? You can't be serious. Putting beautiful
equipment like this into the weather(not quite, but almost) is poor
engineering practice at least and at most, a felony. If you insist on
doing this, sell your Elecraft stuff and buy one of the other three
imported brands, but don't expect to get any repair service when it breaks
from environmental abuse.

End of soapbox rant, for now.

Re: K-Line Climate Control

Operating a K3 remotely is one thing. Subjecting it to varying
temperatures and humidity is something else. Obviously, high temps and
humidity will be a problem for any radio. You need reasonable climate
control no matter what.

The reason I'm responding to this is because eventually the only way I
will be able to operate is to place a transceiver in a shed on a
friend's property and use a multiband antenna -all of which will be
operated over the internet. The ambient RF noise in my townhome makes
any HF operating impossible.

A 5000 BTU air conditioner can be obtained from many retailers for very
little money. This would solve humidity and high temperature issues.
Unless the low temperatures are extreme, I don't think its much of an issue.

Re: K-Line Climate Control

In reply to this post by alaparos@w2cs.net

Surprised to see the term "Climate Control". Sorry to be fussy and pendantic but this is not a climate control question. Climate is the long term, local & world-wide, changing of weather parameters/variables. More correctly this would be environmental control of the operation of your rig considering weather changes and even extremes of weather.

I'd bet that doing this will shorten the lives of both the K3 and the
KPA1500, maybe significantly.

Re: K-Line Climate Control

What about creating a Faraday Cage (as done in some offices) by covering
walls, ceilings, floors of apartment with electrically bonded, metal (not
plastic) window screen. Also, follow bonding/grounding techniques in H.
Ward Silver's book published by ARRL?

Just buy a few old tube radios off eBay to restore that were stored in
sheds or garages and look at the all the corrosion from condensation inside
them and you will have your answer. Not a good idea unless you climate
control the shed.

Gary,
I am also considering moving the K-Line (K3S KPA500) to a “shed” (yet to be bought) at the base of my antenna.

But my location is in the Philippines where it is hot, humid and it rains an awful lot (Think Florida without the Oranges)

Are there off-the-shelf containers for such things, or do people run A/C or De-Humidifiers etc ??

Re: K-Line Climate Control

My shop is about 300 ft from our house. In a corner of my 25' x 50'
building {not a garage}, I have enclosed a 12' x 15' area, where I
insulated the walls and ceiling. This is my radio room which has my
test bench and equipment from a former service repair business. $$$$
investment. Due to the investment in the equipment and radios, I
maintain a constant environment year around. Heating, cooling and
humidity control.

Most electronics components have a "storage" environment set of values
and an "operating" set of values. These are usually values of
temperature and humidity, and in some cases altitude.

Just do what and as you think regarding the value for your equipment and
hobby. Personally, I certainly would not expose my Elecraft equipment
to long term uncontrolled environment conditions without expecting to
have problems.

A little more than a shed but you might consider a pre-fabricated communications shelter if you can afford it. You can get them complete with power and climate control. Here is an example:

There certainly are such containers - with built-in HVAC - used for
commercial communication sites in such places but they make the cost of
a K-line look like pocket change.

The Bard cooling units on these things alone will set you back maybe $3500 each. One of these would be a great solution. Larger ones would actually make a really nice shack. But I know, because I used to bid these out and manage contractors putting them in, they are definitely not “economical” unless you’re quite well heeled. :-)

But sheds and pre-fab shelters don’t have windows.

Seems like we might be getting toward OT here?

A “sawzall”, a trivial bit of framing, and a pre-hung window can fix that very quickly.

If you are just installing a “window mount” AC unit, you can save (a lot of) time and money by skipping the window and put the AC unit directly in the hole.

If you want the structure to last, seal around the outside to prevent water ingress and long term damage.

If you want your electronics to last, don’t abuse them by storing or running in hot, humid environments.

Re: K-Line Climate Control

One doesn't need a window. Use a saws-all, cut the correct size based on the AC, frame it in on the outside and inside. Place and secure the AC in the finished hole.

Re: K-Line Climate Control

In reply to this post by Grant Youngman-2

The KEY to environmental control is ultimately to control humidity.
Water (liquid/vapor) kills electronics.

Now, HOW you control water is the key to longevity. Basically, you have
three factors that impact how well you control the environment:
temperature, pressure, and humidity.
If you have all the money in the world, you can produce a standard
temp/pressure/humidity in any size volume you want.
Money is often the ultimate limiting factor. Sometimes it is
availability of power.... AND money.

For a LOT less than they charge for these communications modules, you
can produce an environment for your remote electronics that will insure
effective performance and longevity for the components.
It costs some money, but if you have the skills, energy, and time, you
can DRASTICALLY reduce the amount of money it will take to address the
situation.

To the OP: WHAT ARE YOUR REQUIREMENTS? Volume of artificial
environment? (length, width, height.... a box, a small room, a radio
station?)

What equipment do you need to put in the environment.... What are the
operating and non-operating specifications for EACH piece? What is the
most restrictive spec for each of the following: humidity, temperature
(high and low), pressure, etc.

Bottom line.... you gotta keep the water away from the electronics....
this involves 1) stopping the air pumping action from outside to inside
via thermal/temperature and pressure delta pumping action, and 2)
keeping the water vapor that IS inside the environment in a VAPOR state
and stopping it from condensing. There are other conditions and
mitigation techniques for each.

But until we know the requirements, we cannot begin to construct a solution.

IDEALLY, if you use a window unit, it should NOT be put in a window, but
a custom cut/constructed hole in the side wall with top quality sealing
solution.

I prefer a sawzall to rendering a window inoperable.

I use a Peco TF115-001 (about $30) wired to a portable oil filled electric heater on low. Thermostat set to 55F is enough so gear isn't cold enough to form condensation as outside temps warm in the morning. I'm in coastal N California, so cooling not required in the shack.
