Radio and amplifier environmental specifications

Bill Frantz
I'm trying to specify what is needed for a radio room here at
the Rivermead continuing care community. If I place an amplifier
or a radio (K3 w/remote rig or a K4) in a shack near the
antenna, what are the environmental requirement for that shack?
What temperature range, since the minimum weather shelter might
range from -20F (-30C) to 100F (40C)? What about humidity?

I couldn't find a specification in my copy of the K3S manual and
I haven't tried the KPA1500/KPA500/KAT500 manuals.

Does anyone know the specs?

TIA & 73 Bill AE6JV

I’ve figured if I’m comfortable the radio should be also.

I've never seen an operating temperature spec for any ham equipment. When we built our remote station (K3/KPA1500 in an insulated 20 ft shipping container), my main concern was not so much temperature as condensation. Moisture is a slow-motion disaster for unsealed, uncoated circuit boards. Ventilation can help, but there are times when everything is going to be soaking wet. And then there’s dust. So we added a Mitsubishi 1-ton mini-split heat pump with the sepoints pretty wide (55 and 80 F). It doesn't run much but the equipment is dry and clean. Themostat is a Nest, controlled from an app.

I just went to Icom, Yaesu and Kenwood sites and they quoted operating
temperature ranges for all {amateur} transceivers. This was either under
a dedicated 'specs' area for each model or within the Owner's Manual
[PDF] for each rig.

73, Paul.

All of our Microwave Sites and telecommunications facilities were kept at 70
degrees and 50 percent humidity.  That was from Chicago to New Orleans,
Mobile and Kansas City.  I also had a 2 meter repeater here in Paducah and
it seemed to like the environment it was in.  Matter of fact that's the
parameters I keep my own home in.

Probably the biggest limiter will be the LCD. LCDs do not like cold temperatures - anything below freezing can be a problem, but below 10 degrees they tend to stop working and turn black. Yes, the do recover when it gets warm - usually.

I wouldn’t want to subject my station to anything below freezing (or close, for that matter). But then I wouldn’t have moved from Silicon Valley to frozen New Hampshire either… ;-)
For the record, Bill and I are good friends - we are both WVARA and NCCC members, and we used to live just a few miles apart...

73!
