TheEC: We Are Watching ALL the Things

RIPR WATCHES *ALL* THE THINGS
Credit Aaron Read RIPR

Thanks to a recent major grant that RIPR applied for and received, we have added several 40-inch LCD TV screens to Studio A, our "air studio".   Four total, plus a fifth existing LCD TV.  So we can watch ALL the things!!!

TheEC: New STL Dish at 88.1 - INSTALLED!

UPDATE @ 1pm : 88.1FM is back at normal power!  Pics are available on our Twitter feed here, here, here and here.   By the way, many of these pics were taken with a stock iPhone 5S using this telephoto lens attachment.  Pretty good for $45!

----------------------------------------------

On Wednesday June 18th, beginning around 9:30 or 10am, 88.1FM will be running on the backup transmitter & antenna for a few hours to install new equipment on the top of the tower.   We must run on the lower-power backup for the health & safety of our tower climber.

The backup operates using a one-bay vertically-polarized omnidirectional antenna and about one-tenth our normal power.   

THIS WILL NOT IMPACT OUR 91.5 OR 102.7FM SIGNALS, NOR OUR WEBCAST.

Keep watching our Twitter feed for updates.

TheEC: "Normal Accidents"

Jack Lemmon in The China Syndrome

Most people have heard of the "Three Mile Island" nuclear power plant accident of 1979.  But it's famous among engineers for being a "normal accident", in that there wasn't any one thing that nearly caused a meltdown of catastrophic proportions...it was a series of little things inside a highly complex system that all happened as part of "normal" operations.   None of which, by themselves, was terribly problematic.  But they all happened at once, and that was a problem.

TheEC: Satellite Dishes and Snow

Credit Aaron Read

  Oh the weather outside is frightful…

Actually, this winter we haven’t seen too much snow.  Nevertheless, snow is something of a chore for us at RIPR, because it builds up on our SATELLITE DISH, which blocks the satellite signal.  Specifically, our NPR and BBC signal, and that means when it snows = dead air on RIPR!
