The FCC: Spectrum management in the public interest

Alternative title: Who will really benefit from all digital AM HD Radio™?

Remember when, at license renewal time, radio and TV stations played this announcement:

On (date of the last renewal grant), (station’s call letters) was granted a license by the Federal Communications Commission to serve the public interest as a public trustee until (license expiration date)…

Emphasis mine.

There seems to be a disassociation between those words and the actions of certain broadcasters who view their licenses as a matter of fact and have little regard for the public interest. The FCC exacerbates the situation with the attitude that everything, including the entire radio frequency spectrum, is for sale to the highest bidder. John Anderson (DIY Media) has a great article on how big business interests game federal regulators into doing what they want. This happens in all sectors; banking, agriculture, energy, health care, media, military and so on. There are many examples of shoddy regulators and big business gone wild over the last ten years to fully prove this theory. If you don’t believe me, do a little research. There is no reason to think that the FCC is different from any other federal regulatory agency.

The vast majority of mass media outlets in the US are owned by just six major corporations (see below). Radio remains the only piece of the mass media system that has not been completely rolled up in consolidation. Currently, there is a small number corporate radio owners who own a combined ~2,300 stations and one public broadcasting network that accounts for another ~900 stations. I include public radio here because the majority of those station’s upgrades were footed by the taxpayer though grants from the Corporation for Public Broadcasting. That leaves a majority of the approximately 8,500 radio stations that are still owned by a diversified collection of medium and small groups and individuals.

Forcing radio stations to adopt the proprietary, all digital HD Radio™ as the broadcasting standard would, in effect, drive many of those small owners and individuals out of business because of the exorbitant costs for equipment upgrades, antenna modifications, and licensing fees. This would create a new wave of consolidation as smaller groups and single station owners sold out. Any remaining small station owners will not have the legal wherewithal to fight against the coming waves of digital interference on both the AM (medium frequency) and FM (VHF) bands.

Therefore, the short answer to the question; who benefits from an all conversion to all digital HD Radio™ is iBquity and its investors, many of whom are found in the list of consolidated media corporations below. Who looses? Just about everyone else; small and medium group owners, independent radio owners, listeners, communities of license, radio employees, advertisers etc. For those sitting on the fence, thinking “I’ll just do my job any everything will be just fine.” Full implementation of HD Radio™ will destroy what is left of broadcasting in this country. Radio is already on shaky ground as a result of product dilution, staff cuts, mediocre programing and competing media systems. One more step backward, such as adopting a technically flawed digital system that works worse than its analog counterpart, and the remaining listeners may just say “screw this,” and abandon radio altogether. When the last radio station is turned off, what do you think will happen to your job then?

At the big NAB Las Vegas confab, FCC commissioner Ajit Pai and to a lesser extent, Commissioner Rosenworcel, encouraged people to write or email them with their ideas on how to revitalize AM radio. I suggest we take advantage of that invitation and tell them what HD Radio™ really is. There is a shrinking window of opportunity to join the discourse and be heard, now is the time.

Let not any one pacify his conscience by the delusion that he can do no harm if he takes no part, and forms no opinion. Bad men need nothing more to compass their ends, than that good men should look on and do nothing. ~John Stuart Mill

What is at stake? The future of diversified media and radio broadcasting in the US.

Sidebar: Mass Media Consolidation

Can the public trust a mass media that is owned mostly by six mega corporations to honestly and without bias report news, current events, investigate corruption, and be a government watch dog? History says no.

Suppression of ideas

I found this video called Empire of Noise about broadcast radio jamming. It seems to be about ten years old and is a post-cold War documentary about the jamming of radio signals by the USSR, Warsaw Pact counties, and China. It is an interesting look into the extent and expense that governments will go to suppress counter thoughts and ideas.

The video is quite long, and there are stretches of jamming noise that can be annoying, but perhaps that is the point. It is worth the time if interested in history and radio broadcasting. You know what they say about history; those that do not understand history are destined to repeat it.

A few of the highlights:

The former Soviet Union had the most extensive jamming network of anyone on Earth. There were groundwave jamming centers in eighty-one Soviet cities which consisted of approximately 10-15 transmitters each in the 5 KW covering the medium and shortwave frequencies.
Each groundwave jamming station consisted of a transmitter site and a receiver/control site. The receiver site possessed lists of frequencies to monitor, when objectionable material was heard, the jamming transmitters were turned on.
There was a skywave jamming network consisting of 13 jamming stations with 10 or more 100-200 KW transmitters in each. There were some transmitters in the 1,000 KW power range. These were located in Krasnodar, Lvov, Nikolaev, Yerevan, Alma-Ata, Grigoriopol, Sovieck, Novosibrisk, Tashkent, Khanbarovsk, Servdlosk and Moscow (some of these names may have changed). These operated in a similar fashion to the groundwave jammers.
After the sign-off of government stations, Soviet jammers sent a blanketing signal on the IF frequency (most likely 455 KHz) of receivers to effectively block them from receiving any station while USSR government stations were off the air.
Baltic states had 11 jamming stations with approximately 140 transmitters
Ukraine had approximately 300 Jamming transmitters.
Warsaw Pact countries had extensive medium-frequency jamming networks.
It is estimated it takes about 20 times the transmitted power to jam any one signal.

The entire jamming network was hugely expensive to equip and operate, costing several tens of millions of dollars per year.

It is interesting that the US position in all of this was:

Everyone has the right to seek, receive and impart information through any media and regardless of frontiers. Jamming of radio broadcasts is condemned as the denial of the right of persons to be fully informed concerning news, opinions and ideas.

Sounds perfectly reasonable. The free exchange of ideas and information over the internet is something that should be guarded carefully and should not be restricted or censored.

As requested: The old WSBS studio building

Alan asked if I should ever find a picture of the old WSBS studio building to publish it. Here it is:

I found this above the coffee machine in the lobby, nicely matted and framed. I didn’t want to ruin the framing job, so I took a picture of the picture under glass and cropped it, so thus the quality could be better.

I believe this is the original tower from 1959. The current tower stands on a taller concrete pedestal and is further away from the road. I think the roadway was widened and raised at some point, thus the new building sits higher in relation to the tower base. In any case, it little bit of radio history.

Moving and upgrading a translator

Something that I eluded to in a previous post, we finalized the move of the WSBS translator, W231AK, from the Fairview Hospital in Great Barrington to the side of the AM tower.

The move was started by hanging a new Shively 6812B antenna from the side of the AM tower, located off of US 7, north of Great Barrington. This is a half-wave-spaced circularly polarized antenna.

While this work was going on, some guy from OSHA showed up and started taking pictures without asking permission or telling anyone who he was. We informed him that he was on private property and asked him his reasons for being there. He got in his car and left, no doubt to a parking lot down the road so he could keep the tower climbers safe… mostly from themselves… by levying huge fines for free climbing… Wasn’t there something in the news about the government running out of money? Anyway…

WSBS had been using this translator for a few years. The advantages for the station from the translator move are greater power output (from 35 watts to 250 watts ERP) and less operating expenses in the form of TELCO line charges and roof top rental at the Hospital.

In addition to that, the reliability of the translator should increase, as there have been several instances in the past when TELCO line problems have taken the translator off the air for days at a time.

W231AK new transmitter, WSBS base current meter below

The transmitter for W231AK was changed from a Crown 35 watt unit to a BW Broadcast T600. These units are made in the UK and it is an all-in-one processor/exciter/transmitter. We took the cover off to make a few configuration changes and the entire unit is very well made.

One of the nice features of this particular transmitter is the screw-down clamping method of connecting the RF devices. Lets face it, unsoldering MOSFETS is a PITA. This screw down clamp eliminates all that.

The audio input and processing board is pretty neat too.

There are several different processing settings which we played around with. All in all, it seems like a pretty solid unit and I would recommend it to anyone looking for a low to moderate power transmitter.
