Technical Statement Kaix(Fm) Casper, Wyoming, Channel 202C2 Cedar Cove Broadcasting, Inc Fcc Form 340 – Modification of Construction Permit February 2020

TECHNICAL STATEMENT KAIX(FM) CASPER, WYOMING, CHANNEL 202C2 CEDAR COVE BROADCASTING, INC FCC FORM 340 – MODIFICATION OF CONSTRUCTION PERMIT FEBRUARY 2020

This Technical Statement is prepared on behalf of Cedar Cove Broadcasting, Inc.,

licensee of KAIX(FM) Casper, Wyoming, facility ID 92997. KAIX(FM) is proposing to

modify its outstanding Constructed Permit, BPED-20190912ABJ. KAIX(FM) seeks to

relocate to a new existing tower site on the same Casper Mountain Communication site,

FCC registration number 1008931, and increase its ERP to 0.85 kilowatts (850 watts),

with circular polarization, and antenna to increase its center of Radiation Height AMSL to 2480 meters and 559 meters HAAT. KAIX(FM) seeks to “one step” channel change from 202C3 to 202C2.

It should be noted that KAIX recently changed call sign from KEZF to KAIX effective on February 8th, 2020. Hence some of the exhibits still show KAIX at KEZF

since the databases have yet to show this update in call signs.

The new operation was evaluated for compliance with all of the Commission technical rules and regulations for Non-Commercial FM broadcast stations.

Compliance with Section 73.509 in regards to interference to other stations was determined as follows:

Figure 1 – Channel Interference Study. Shows compliance with interference contours toward other stations. There is apparent overlap with KRKY-FM Douglas,

Wyoming on channel 201C3. However, there is no longer overlap with KRKY-FM

Douglas, Wyoming. KRKY-FM is now operating on channel 204C3 under Automatic Program Test Authority under Construction Permit BPED-20190912ABI. KRKY-FM

has filed for a license to cover this CP, file number 0000101347.

Figure 2 – Predicted 60 dbµ principle coverage contour for compliance with community coverage.

The application was determined to meet or exceed all of the technical requirements for a FM Non-Commercial Station set for by the Commission.
