Please find the coordination report, Micronet File Number J1815212, attached. As permitted by waiver pursuant to Public Notice DA 18—398 (April 19, 2018), the application referenced above was initially filed without a frequency coordination report. Therefore, the authorization is expected to contain Condition Code 90472, stating that the Earth station is not entitled to protection from stations operating in the fixed service. Now that the coordination report is available, we respectfully request to have this language replaced by Condition Code 90471, stating that the Earth station is protected within the limits established by the attached report. It is understood that this change will require the application to be placed back on the Accepted for Filing Public Notice. Please contact the undersigned if you have any questions. Sincerely, &MQse\, Daniel G. Ryson Associate Director of Spectrum Management CBS Communications Services Inc. (202) 457—4074 dryson@cbs.com
