TheEC: Air Conditioning at 88.1FM

Regular readers of the ENGINEER'S CORNER might recall my story about air conditioning at our 102.7FM transmitter in Narragansett Pier.   Well now I'm pleased to report that we have air conditioning at 88.1FM WELH in Seekonk as well!

In many ways, this is an even bigger deal; 102.7 had a hefty vent fan system that could move a lot of air.  Sure, if the air outside was hot, it means the air inside was hot, too.  Usually you can't cool a room using outside air below about +10F degrees above outside air temps.   So if it's 90F outside, it's 100 to 105F inside...ugh!  

And at 88.1, we didn't really have even that.  The transmitter site is an 8x10ft shed with a single 12 inch desk fan blowing air out one of the wall vents, and no insulation whatsoever on the walls or ceiling.  Temps routinely broke 120F inside, even when it was only 70 to 80F outside.

Department of Health Cracking Down On Ambulance Company

Imagine riding in an ambulance without heat. That’s apparently been the reality for some people who use the New England Ambulance Company.  The state Health Department is putting a stop to the practice.

The Rhode Island Health Department has ordered the New England Ambulance Company to stop running vehicles without heat.  The department says it will issue fines of 100 dollars a day if the Johnston firm continues to do so.

TheEC: Air Conditioning at 102.7FM

Air conditioning.  Cool heaven for those who have it, blazing hell for those who don't.  It didn't used to be terribly common in broadcast engineering, but it's become moreso in the last ten years.  The reason is that, more and more, audio processors, RDS encoders, audio encoders/decoders, studio/transmitter links, remote control systems, and even the transmitters themselves, have all become increasingly "computer-like" with IC's, hard disk drives, power supplies, electrolytic capacitors and the like.   All things that fail quickly when operated in temperatures above 80 or so, and the warmer it gets, the faster they fail!

Rhode Island Weather: A Heat Wave?

If you’ve stepped outside today, you’ve most likely wanted to step back inside as the temperature in parts of Rhode Island is into the low 90’s.

The high temperatures are expected to extend through Sunday, with highs into the low 90’s and high 80’s.

Though the term “heat wave” has been thrown around, Allen Dunham, a meteorologist with the National Weather Service, says there must be three consecutive days of 90 degree weather for a heat wave.
