Longtime Engineer's Corner readers know that we've had, well, "issues" with the STL or "Studio/Transmitter Link" for our 88.1FM signal in Providence. The STL is what carries the audio from our studios in downtown Providence to the transmitter/tower at the Wheeler Farm in Seekonk.
Now a couple weeks ago we revealed that half of a new wireless microwave STL was installed, and that the other half would be installed soon. Today, we fired it up for the first time and the results were gratifyingly positive!
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.
The morning of April 30th saw several odd "dropouts" in the audio on 88.1FM, usually lasting 5 to 8 seconds each, happening as often as 2 or 3 times a minute, but more commonly once every 10 to 15 minutes.
There was also an odd "repeating audio" effect some people noticed, when the audio came back.
