TheEC: 102.7 Shutdown for Tower Work on March 28th

Beginning at 10:00am on Saturday March 28th there will be an extended outage of RIPR's 102.7FM signal.   It is expected to last several hours at least, possibly until sunset (around 6:30pm).

We may be able to continue operating at reduced power.  But it's likely that 102.7 will just be completely off the air.   Please note: whenever 102.7 is off, our WCVY 91.5FM signal in Coventry will be off as well.  (it gets its content via a radio receiver tuned to 102.7)

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.

UPDATE 3:30PM​  Taking advantage of the downtime, we swapped in the new BW Broadcast TX300v2 transmitter to replace the aging BE FX50 & QEI/LPB FM150SS combo.   The 91.5FM signal should be a little better than usual now.

TheEC: Solar Outages

A Galaxy-model Satellite.

It has to do with our satellite downlink from NPR. We have a hefty 13-foot-diameter satellite dish, located in North Providence; there's no room for it at One Union Station! It points to "Galaxy 16," a telecommunications satellite in "geostationary" orbit that all NPR stations use.

"Geostationary," also popularly referred to as "geosynchronous," means that the satellite orbits the Earth in sync with the Earth's rotation...about 6800 MPH. That's pretty fast, but the key is that it's the SAME speed for both. So from our perspective here on Earth, the satellite just floats there, not moving, over 22,000 miles up in the sky! In Galaxy 16's case, the satellite is at 99.0 degrees west longitude, meaning it's fixed above a point on the equator over the Pacific Ocean, about 500 miles west of the Galapagos Islands (near Ecuador).

In general, geostationary orbits work great for communications satellites like for NPR, but there's a catch: twice a year there are a few days when, the Sun appears to pass right "behind" the satellite for a few minutes each day. The Sun puts out so much energy on ALL frequencies that it completely swamps the satellite's own signal, so we lose all NPR, BBC and other satellite programming.
