Hard to understand, the link connects to the broadcast server, buffers, then no sound. Need someone with more technical knowledge to explain, but could it be a server that decodes the audio signal that is off. The radio station IP is reachable since you can connect.
To be fair to the Cindi and the alumni assn., she/they were very helpful last year and I've no doubt they will be again. She may have picked up my email from home, wherever that is, and is probably not working today.
