TheEC: Tower Climbing & RF Safety

This past Saturday, AT&T Wireless performed a hardware upgrade to their cellphone antennas that're on the same tower RIPR's 102.7FM signal is, in Narragansett.   This entailed two tower climbers spending nearly six hours up on the tower, within about 20-30 feet of our Shively 3-bay antenna.  Fortunately between the laws of antenna physics, and judicious reduction in transmitter power, RIPR could stay on the air without jeopardizing worker safety!

102.7 Tower Work Apr.11 - Possible Off-Air

UPDATE: More tower work Saturday April 11th beginning at 10am.

The second AT&T crew is returning for another try for antenna replacement on Saturday 4/11 starting at 10am and lasting most of the day.  

Based on previous experience, we are hoping to maintain normal operations on 102.7...or at worst just run at half-power.   Check the @RINPR twitter feed for updates.

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: Better HD Radio for 102.7FM

Friday night and mid-day Saturday (Nov.14 & 15) ended up being a bit of a saga for what was supposed to be a routine upgrade for our 102.7FM signal in South County.   So first off, an apology to our RIPR listeners on 102.7FM, and to MVYradio's listeners to the 96.5FM signal in Newport.  There were several dropouts, periods when RIPR was on backup transmitter (and thus 96.5 was off entirely), or when both transmitters were down.

Exactly what happened could be described as an avalanche of minutiae, but I'll lay it out as best I can.

TheEC: New NPR Clocks

Starting on Monday Nov.17th, the clocks for Morning Edition, All Things Considered (both weekdays and weekends) and Weekend Edition  will be changing.  

Today's Engineer's Corner is co-authored with our Operations & Production Manager, James Baumgartner.  He and I are the ones directly responsible for organizing all the clock changes' impact on Rhode Island Public Radio, and we've put together this synopsis of what the changes mean for our listeners.
