The Williamstown repeater is currently experiencing an issue with its RF link into the CVARC linked repeater system.
Based on some initial diagnostics, there appears to be a issue with the antenna system of the link radio which carries radio traffic from Cabot and Lincoln Peak into Williamstown. The issue is likely being caused by antenna icing, or damage from falling ice.
Because of steeply decreased antenna performance, there isn’t enough RF signal strength at the link receiver to overcome interference from adjacent in-band high power transmitters at the tower site. Because of this, signals from the link may seem strong one moment and completely unreadable the next.
The Williamstown repeater itself is functioning properly as a standalone repeater. Cabot and Lincoln Peak are still linked by RF. There is no evidence to suggest problems with basic repeater functionality at this point.
Unfortunately, I am out of town for a week starting early tomorrow morning. I will promptly investigate the issue further on my return and will work towards implementing a solution. In the mean time, I may make the decision to disable the Williamstown link altogether until it is repaired. I will notify the club if this decision is made.
I appreciate your understanding with this issue, and I will post updates as they become available. I apologize for any inconvenience this system failure has caused.
