In light of ongoing issues with the Studio/Transmitter Link (STL) for WELH 88.1, we have implemented a new STL schema. If you heard a lot of odd audio dropouts on 88.1 today, that was the reason.
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). Best of all, I was able to put in a new(er) Orban Optimod 8100A audio processor to replace the less-capable Inovonics DAVID-III. There's a little sibilance still, so I need to tweak the settings. But overall the sound should be much louder, fuller, and more consistent.
UPDATE (Jan.10): Verizon sent a trio of techs today to examine the Digital Lines. They found a splice point on a pole near the Wheeler Farm end of the circuit where water had gotten past the weatherproofing. The splice was re-done, with fresh (and better) weatherproofing sealant applied, and a weather box placed around it.
That's likely the culprit here: the problems started during the snowstorm, so probably water got in there and expanded/contracted repeatedly as the water froze and melted. That expansion wreaks havoc with (relatively) fragile copper telco wiring.
As of 3pm we are back on our main STL. We've noticed the volume levels seemed to have changed somewhat with this repair, too, so we're still tweaking things.
