I received an email reply to my problem (low audio on locals and audio dropouts) and it confirmed what kb7 said. Here is the text,
"We are aware of the audio levels on your locals. This item has made what we call the Hit List. This means that we are meeting daily on the issue. Your locals have been converted to digital. We are using new equipment. We realize your issue may have to do with this equipment. The engineers were working on it again today. The digital conversions are new for both us and the provider. It may take sometime for the locals stations and their providers to work out the kinks."
In addition to the audio problems I mentioned the periodic video freeze that occurs every now and then. Here is their response to that.
"As for the freezing on your 522, we have a few other complaints for this issue on the 522 and 625 receivers. We are going to add your email to the bundle that we planning on taking to the receiver team soon, so good timing on your part!"
Some of my locals have improved but a couple are still very low and the audio dropouts happened again Friday night. Here's hoping they get it sorted in the next week or so.
