That means the repeater will be connected to VE4MAN, VE4WPG/VJ, VE4MIL and VE4FAL when all the links are working properly. If the link is down, you can access remote repeaters using the *500 DTMF sequence. If the link is up, busy, and you would like to make a local contact; press *505 AFTER asking for a "break". To bring the repeater to normal (linked), press *500. From elswhere in the system use #47 as the preaccess for the CDN controller. Use the same codes for up and down; link on - #47 500 Link off - #47 505 Note: These codes access the Morris repeater controller. If you wish to remotely control other repeaters on the system see the MRS web site, or refer to your MRS repeater guide mailed out with your membership.

Operational update:

January 2017

Repeater operation is a bit sub-nominal due to damage to the VHF antenna array. The top element has become partially disconnected from the mast and causes noise and interference as the assembly moves in the wind and due to vibrations on the elevator head. MRS is looking to replace the antenna when funding and time allows.

The link to VE4MAN (Starbuck) is not currently available, the link radio was removed for re-tuning. SHould have it re-installed shortly.

The link to VE4TOM (Winkler) installation is pending, subject to approval of antenna and feedline apparatus. This equipment could be installed quickly once approvals have been issued at the site.
