Groton Trail Run – repeater info and aid station access

Here is information for volunteers this Saturday.

Repeater: 447.42 MHz, negative 5 MHz offset, 67.0 Hz PL tone required for access.

Directions to Boulder Beach
Take Route 2 through Plainfield, and continue on into Marshfield. Turn right onto Rt 232, and continue through Peacham. Keep driving on 232 until you see the entrance for Boulder Beach State Park on the left – this is Boulder Beach Road. Continue straight and you will reach the entrance to Boulder Beach.

Coldwater Brook Bridge aid station
Approximately 2 miles from Boulder Beach Road at the end of Coldwater Brook Road. Coldwater Brook Road (unsigned) is on the left 1.8 miles from Route 232 on Boulder Beach Road. (Coldwater Brook Road is directly across from Log Pile Lane on Boulder Beach Road.) Google maps may show this as “Gravel Pit Road” – they mean it! A 4WD/AWD vehicle with good ground clearance (such as a Subaru Outback) is preferred to reach the aid station. The path is rocky and bumpy and makes for slow goings. Leave yourself plenty of time to reach the aid station. Park in the clearing just before the bridge and make sure not to block the path.

Lanesboro Rd aid station
Lanesboro road is right across the Owl’s Head Mountain entrance on Rt 232. The aid station is 500ft down the hill.

New Discovery aid station
New Discovery Campground 4239 VT RT 232, Marshfield, VT 05658. After entering the campground, follow the road 0.5 miles toward Osmore Pond. Aid station is on the right.

Telephone Line Trail aid station
100 yards north along the Telephone Line Trail from the back of campsite #11 at Big Deer Campground.
Big Deer Campground, 1467 Boulder Beach Rd, Groton, VT 05046
Park at the campground entrance or at campsite 11 (if allowed) and walk to the aid station.

Kettle Pond
This aid station is at the Kettle Pond day use parking lot, off Rt 232.

Williamstown Repeater Link

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.
