    Oregon FM Translator Sold

    MEDIA INSTITUTE FOR SOCIAL CHANGE is selling K219KU/NEHALEM, OR to CASCADE EDUCATIONAL BROADCAST SERVICE /ABN/ XRAY.FM for an undisclosed price. The translator will rebroadcast Eclectic KXRY (XRAY.FM)/PORTLAND, which CASCADE operates under an LMA with licensee COMMON FREQUENCY, LLC.

    Why would they want to rebroadcast KXRY in Nehalem?

    Does this have to be fed over the air like K296FT or can they just connect it to an internet feed?

    Very strange. The only thing I can figure is that Media Institute for Social Change Executive Director Phil Busse might need to divest of this radio station so that they can invest in another LPFM? Phil Busse and Media Institute have a regular show on XRAY.

    “Does this have to be fed over the air like K296FT”

    No.

    “can they just connect it to an internet feed?”

    Yes. They can use any means to feed it. That’s primarily because the translator is a non fill-in and in the reserved band (Channels 201 – 220). There are a few other requirements, too.

    K219KU currently broadcasts on 91.7 MHz with 28 Watts ERP, from a height above average terrain of 159.7 meters. There is a construction permit on file that would change the frequency to 91.1 MHz, raise ERP to 100 Watts but move the transmitter location to one with a height above average terrain of -282.4 meters. The predicted coverage area for the construction permit is much smaller than that of the current facilities, due to the lower antenna height.

    Questions:

    • What benefits are there to the construction permit; why broadcast with more power, only to achieve a reduced coverage area?
    • What about the 91.1 MHz station in Tillamook, KTMK; would it have to change frequencies, install a directional antenna, or go off the air in order for the K219KU construction permit to be built?

    Paperwork has been submitted.

    Alfredo, the change appears to be related to the original tower site becoming unavailable, precipitating filing for the minor change and an STA to be silent.

    It seems fishy to me that in the CP, the height above mean sea level of the antenna is stated as *minus* more than 400 feet, since the location is very close to the bay

    Using Google Earth, the HAMSL of the proposed site is 18 meters plus 10 meters for the mast as per the application for a total height for the radiation center of 28 meters AMSL. When you plug that in to the FCC HAAT calculator you get -126 meters HAAT (for translators use 12 radials).

    https://www.fcc.gov/encyclopedia/antenna-height-above-average-terrain-haat-calculator

    So it does appear that the entries under Antenna Height Above Average Terrain and Antenna Height Above Mean Sea Level are incorrect, but this is a Todd Urick application so no surprise.

    The smallest value you ever can use for HAAT when calculating power is 30 meters. Any actual HAAT less than that is ignored and 30 is substituted for that number. In fact, in this case for a non fill in translator, any HAAT less than or equal to 107 meters HAAT can go up to 250 watts as long as you protect the appropriate contours of interfering stations, which in this case does matter (KTMK). The proposal does call for a DA but whether the requested 100 watts is correct is anybody’s guess since the height numbers are all screwed up and would effect the theoretical propagation curves from which the contour is generated.

    Perhaps Todd entered in the red herring numbers just for the halibut? ๐Ÿ™‚
