These three postings on WBXZ-DT-56 RF-17 Facebook page:

We had a transmitter failure. We must order a new part, in the meantime, we are operating at a greatly reduced power. We will keep you updated as repairs are made. It may take several days. -- March 27

Well, if transmitter problems weren't enough, high winds have knocked off our Cozi feed. We will fix the feed when winds allow us access. -- March 28

A soft launch of Heartland is available on 56.6. We are testing the signal and working out the bugs. Also thank you for your patience with COZI as we had issues with it over the last few days. The Retro signal has been somewhat jittery and once we get the new equipment up and running that should be gone. We will be adding BUZZR soon and are awaiting the final word on MOVIES!.  -- March 22
