&nbsp;</p><p>And at 88.1, we didn't really have even that. &nbsp;The transmitter site is an 8x10ft shed with a single 12 inch desk fan blowing air out one of the wall vents, and no insulation whatsoever on the walls or ceiling. &nbsp;Temps routinely broke 120F inside, even when it was only 70 to 80F outside.</p><p> Thu, 22 May 2014 14:17:53 +0000 Aaron Read 33986 at http://ripr.org TheEC: Air Conditioning at 88.1FM TheEC: Audio Dropouts on 88.1FM http://ripr.org/post/theec-audio-dropouts-881fm <p><span style="line-height: 1.5;"><strong>UPDATED 5/8/2014.</strong></span></p><p><span style="line-height: 1.5;">The morning of April </span>30th<span style="line-height: 1.5;"> 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.</span></p><p>There was also an odd "repeating audio" effect some people noticed, when the audio came back.</p><p>Read on for the explanation of both!</p><p> Wed, 30 Apr 2014 16:42:25 +0000 Aaron Read 32862 at http://ripr.org TheEC: Audio Dropouts on 88.1FM TheEC: 88.1 Studio/Transmitter Link http://ripr.org/post/theec-881-studiotransmitter-link <p></p><p><span style="line-height: 1.5;">In light of ongoing issues with the Studio/Transmitter Link (</span>STL<span style="line-height: 1.5;">) for </span>WELH<span style="line-height: 1.5;"> 88.1, we have implemented a new </span>STL<span style="line-height: 1.5;">&nbsp; schema. &nbsp; If you heard a lot of </span><a href="http://ripr.org/post/theec-digital-chirps-881" style="line-height: 1.5;">odd audio dropouts on 88.1 today</a><span style="line-height: 1.5;">, that was the reason.</span></p><p>The good news is that we should have a pretty good temporary solution in place, and a solid path for a permanent solution is on the horizon (tentatively scheduled for mid-March). &nbsp; Best of all, I was able to put in a new(er)&nbsp;<a href="http://www.optimod.fm/">Orban Optimod 8100A</a>&nbsp;audio processor to replace the less-capable&nbsp;<a href="http://www.bswusa.com/Broadcast-On-Air-Processing-Inovonics-718-David-III-FM-Broadcast-Processor-P2989.aspx">Inovonics DAVID-III</a>. &nbsp;There's a little&nbsp;<a href="http://en.wikipedia.org/wiki/Sibilant">sibilance</a>&nbsp;still, so I need to tweak the settings. &nbsp;But overall the sound should be much louder, fuller, and more consistent.</p><p>Read on for more details...</p><p> Tue, 28 Jan 2014 03:08:11 +0000 Aaron Read 28255 at http://ripr.org TheEC: 88.1 Studio/Transmitter Link
