A phone call to the ECFS Help Desk cleared up confusion regarding the deadline for comments. The employee explained that ECFS received the Petition from the Petitioner (ARRL), assigned and posted RM-number 11828 on the 28th of February. This is the date it was posted internally at the bureau. ECFS in turn released the Public Notice on the 13th of March. She stated that the deadline for filing comments falls 30 days after the release of the Public notice, which will fall on the 12th of April, 2019.
