Is it time to eliminate the mileage tables from FM assignments? 10/4/11 - The FCC has received a petition for Rulemaking to amend 73.215 - which has been used to permit stations on the reserved band that are nominally short-spaced according to the separation tables - to include all stations. The idea is to allow applications to no longer protect the maximum possible contours of an operating station, allowing other stations in areas where the existing operation, or terrain shielding, Another requested change that appears in comments addresses a technical anomoly where stations must assume in their calculations an antenna buried underground. The FCC page where you can see the Petition and the comments on RM-11643 is here. Here is a Guest Commentary by Dana Puopolo, CE of WURD, Philadelphia: [10/4/11] Today I filed comments in an FCC proceeding where I proposed the Commission radically change the way FM stations are allotted and classified, and current stations modified. I also proposed a new Class of FM station. Below is a copy of my FCC submission. I believe that it is well past time the Commission come into the 21st century. For example, the entire United States’ terrain data is digitized with 3 second or better accuracy, yet the FCC still relies on the 30 meter terrain data assumption it has used for the past 40 plus years. The Commission still assumes that radios have 25 dB of second and third adjacent rejections (commonplace in the early 1960s when these rules were put in place) when even the mid priced radios of today have rejections of better then 70 dB. I believe my proposal is a good start - but it is only a start. If you agree (or disagree) with what I have filed-or have ideas of your own then I urge you to also file comments. The dialog is probably more important then the final results.

) TO: Marlene Dortch, Secretary COMMENTS OF DANA J. PUOPOLO Pursuant to Section 1.405 of the Commission’s rules and regulations, Dana J. Puopolo (“Puopolo”) respectfully
submits his comments in the above captioned proceeding. Puopolo is
a broadcast engineer & technician with over 30 years of experience
and has been an FM licensee. He has held an FCC Radiotelephone
Operators license since 1974 and presently holds lifetime General
Radiotelephone Operator License PG0114172. His credentials are a
matter of record before the FCC. In support thereof the following
is stated. -2- Indeed, in New York, Los Angeles, Chicago, and
other cities NON co-located FM stations of different classes have
operated for decades on second adjacent channels without any
problems. In Philadelphia, two stations are IF short spaced-and one
of the two also is third adjacent short spaced with no practical
problems. Respectfully submitted Dana J. Puopolo
