As you know, WCVY <a href="http://ripr.org/post/why-wcvy-was-air-few-days">suffered catastrophic damage to its equipment and facility from a roof leak during a thunderstorm in August</a>.&nbsp;&nbsp; The entire space had to be gutted to the concrete walls, and new electrical wiring and drywall installed.&nbsp; Much of the transmitter gear either took direct water damage (e.g. electricity shorting out) or took indirect water damage (e.g. rust and other corrosion), and eventually a lot of it failed completely.</p><p></p><p>We have put a temporary setup in place with a donated 30 watt transmitter on loan (with the <a href="http://en.wikipedia.org/wiki/Antenna_gain">antenna array's gain</a> factor of 2.1, it's really more like <strong>63 watts</strong> of <a href="http://en.wikipedia.org/wiki/Effective_radiated_power#FM_example">Effective Radiated Power</a>), and a special radio that's tuned to 102.7FM (there's a high-gain FM antenna on the rooftop tower) and puts out the <a href="http://en.wikipedia.org/wiki/File:RDS_vs_DirectBand_FM-spectrum2.svg">composite signal</a> directly into the new transmitter.&nbsp;&nbsp;
