Comments or Questions:


I.   By submitting this form, I certify that I have read and agree to abide by MARC Bylaws, Standards and Procedures; and that the statements above are true, complete and correct to the best of my knowledge and belief.

II.  I understand that if granted a coordination I have six months to have the repeater operational to coordinated specifications, or contact the coordinator for an extension. I further understand that failure to do so will result in immediate loss of coordination.

III. A TDS update/review form is required to be submitted by the trustee of this coordination each year. There is a one year grace period after the first year. After two years without an update being submitted, the coordination will be removed from the ARRL Repeater directory; your repeater can be de-coordinated and any protection offered by coordination will be gone. It is the Trustee's responsibility to see that the Renewal TDS is submitted on time.
