Migrating the existing AM stations to former TV channels 5 and 6

This is one of the possibilities that has been bantered about as a solution for the “AM problem.” The theory goes as such; former TV channels 5 and 6 (76 – 88 MHz), which are not suitable for DTV would be an ideal place for the existing AM stations to move.  That represents a 12 MHz chunk of spectrum, which is much more than the current 1.16 MHz spectrum the current AM broadcasting service takes up (.54 to 1.7 Mhz).  An added benefit is that the VHF spectrum does not have the skywave “problem” that the MF spectrum does, thus many more stations could be licensed to the service.  Everyone would benefit, AM stations would get a new lease on life in the FM band.  The number of stations would increase by several fold, including LPFM, non-commercial and translators.  AM stations would no longer be burdened with expensive directional arrays or sub standard audio quality.

It seems almost too good to be true…

The FCC reportedly promised “take a hard look” at this idea back in 2008.  Four years later, one wonders what has become of it.

A quick search of the existing TV stations licensed to channel 5 and 6 reveals the flaw in this theory.  The FCC has re-licensed many full powered and Low Powered DTV stations to channel 5 and 6 since 2008.

Looking through this data, particularly the digital licenses which were granted since 2009, one an only assume that the FCC has, by de facto, nixed this idea if it ever considered it at all.

The unitless coefficient of Zorch

Zorch is a term used to describe an over voltage or over current condition that usually leads to catastrophic failure, e.g. the power supply was zorched by lightning. There is also a quality to radio signals that defy and exceed theoretical definitions for service contours or power density.  That is quality defined as:

Zorch (adj): The ability of an RF signal to be received in unlikely locations; outside of predicted service contour, in steel structures, underground facilities, tunnels, etc.

It brings to mind the saying, “antennas are not amplifiers and amplifiers are not antennas.”

ERI circularly polarized 2 bay antenna
ERI circularly polarized 2 bay antenna

During the earlier stages of FM broadcasting, there was a notion that costs could be reduced by increasing antenna gain and reducing transmitter size. While theoretically, ERP (Effective Radiated Power) is ERP, broadcasters soon learned that high gain antenna, low TPO (Transmitter Power Output) installations lacked building penetration and had other reception issues.  Realizing that there is a trade off between antenna bays, transmitter power output especially in difficult reception areas, a great debate occurred and continues on what the optimal system is.  The answer is, it depends on the receiving environment.

Where this technical detail can be really important is with lower powered FM stations; Class A and LPFMs to be exact.  They are already battling against bigger stations that have tens or even hundreds of times  more power.  Certainly an LP-100 station has it’s work cut out for it.  The choice of antenna is perhaps one of the most important technical decisions to be made.  Choosing the right balance of antenna type, antenna gain, antenna height and transmitter power output can greatly influence reception reliability and thus coverage area.

A good study of this quality can be had by looking at various LPFM installations:

Station ERP (watts) Antenna Type Antenna Gain (power) TPO (watts)* Coefficient of Zorch
100 1 bay vertical 0.92 127 0.1
100 1 bay circular 0.46 253 0.4
100 2 bay vertical full 1.98 58 0.15
100 2 bay vertical half 1.40 83 0.2
100 2 bay circular full 0.99 118 0.5
100 2 bay circular half 0.70 166 0.7
100 3 bay circular full 1.52 77 0.46
100 3 bay circular half 1.01 115 0.52

*Includes 100 feet of 1/2 inch foam transmission line, Andrew LDF4-50A, loss of 0.661 dB  at 100 MHz, or 0.859 power gain.

Stations should try to get the transmitting antenna as high up as permitted without reducing ERP.  In other words, the FCC allows 100 watts ERP with 98 feet Height Above Average Terrain (HAAT) radiation center in their current LPFM rules.  Being lower in height will reduce the coverage area.  Going over 98 feet HAAT will cause the station’s power to be reduced, which will lower the coefficient of zorch accordingly.  Therefore, getting as close to 98 feet HAAT, which is different than 98 feet above ground level in many places, will net the best performance.

If a singular polarization (horizontal or vertical) is desired, vertical polarization should be chosen, as most mobile reception is by a vertical whip antenna.  For best reception performance, a circularly polarized antenna will work best, as receiver antenna orientation will not effect the signal reception.  A circularly polarized antenna has better building penetration and multi-path characteristics.  The FM broadcast circularly polarized antenna in not a true circularly polarized antenna, it is actually unpolarized.

The use of a multi-bay antenna has the effect of focusing the RF radiation outward, perpendicular to the element stack, thus limiting the radiation directly up or down from the antenna.  This is more pronounced with one half wave spaced antennas, which may be an environmental consideration in heavily populated areas.

Thus, the best coefficient of zorch for an LPFM station would be a circularly polarized, 1/2 wave spaced, 2 bay antenna.  This antenna would have some gain over a single bay antenna, take up less room on a tower than a full wave spaced antenna, offer good RF protection performance for the general public living and working under the antenna, reduce wasted upward radiation and offer good building penetration for the ERP.  It would require a slightly larger transmitter and more electricity, but that trade off is well worth the effort.

LPFM channel finder

A potential LPFM (Low Power FM) filing window may be opening up as soon October/November.  There is nothing official from the FCC about the date, however, several insiders have suggested that this is on the fast track and it may happen sooner rather than later.

This will likely be the last chance for community radio operators to get a LPFM license, as after this filing window, every available scrap of spectrum will have a translator shoe horned into it.  Therefore, now is the time to do some research and get prepared.

To that end, there are two good LPFM channel finders that can be used to determine if a LPFM station can be put on the air.  The first is the FCC’s official LPFM channel finder.  For this tool, one will need to know the latitude and longitude of the proposed transmitter site.  That information can be obtained from itouchmap.com, with which one can find the lat/long of any point on the face of the earth.

The second LPFM channel finder is from REC networks.  This tool is a much more flexible.  For finding possible transmitter location, a street address, zip code, or lat/long can be used.  It also has much more information as it has a provision to use the proposed 250 watt station class and shows every available channel as well as possible available second adjacent channels.

Prometheus radio has a simpler zip code check, which does not give any technical information, it simply states that LPFM channels are available at the zip code which was entered.  Prometheus has good primers on how to start and operate a LPFM station.

If you are a member of a group considering starting a community radio station, now is the time to get going.

The FCC LPFM plan

FCC moves ahead on a couple of different fronts in the LPFM battle.  Cliff notes version:

  1. The 2003 translator filing window question.  The FCC has more or less stuck with it’s plan to keep a minimum number LPFM channels available in the top 150 markets.  This also includes a 50 application limit for the country and no more than one application per market per applicant.  Where conflicts occur, translator applicants get the chance to demonstrate how their application would not preclude LPFM opportunities.
  2. Modifies (eventually eliminates) the May 1, 2009 cut of date for cross service (AM to FM) translators.
  3. The establishment of new LPFM allocations under the criteria of disregarding the third adjacent channel contours.
  4. More stringent requirements for local programming and ownership, especially as a determining factor for mutual LPFM applications.
  5. Allows LPFM stations to own translators.
  6. New class LPFM is established; the LP250.  The 250 watt LPFM stations are designed mainly for areas outside of top fifty markets or for previously licensed LP-100 stations that want to upgrade provided the minimum separation contours are met with existing stations.

The FCC has included the proposed rule changes as appendix A of FCC 12-28.  Standard FCC comment and reply windows apply.

Looks like things are moving along pretty fast.  Others have speculated at a filing window sometime later this year, I’ll not do that.
