So, you call this work?

A trip to the WSPK transmitter site on a pleasant day, or, one could say, another day at the “office.”  Tower painting season is here, I’ll post some more about that later.  This is a nice set of pictures from the top of Mt. Beacon, in Beacon, NY.

Tower farm; two TV stations, Media Flow, one radio station, three translators, several cell carriers, one paging company, some government two-way gear, and a few microwave relays.  The 320-foot guyed tower in the center holds the main (top) and backup (bottom) antennas for WSPK:

Tower climbers ascending a 320-foot tower.  This picture (and all the others as well) was taken with my HTC smartphone camera, proving the old adage, sometimes it is better to be lucky than good:

All in all, not a bad day.

Engineering Radio is Two Years Old

Happy birthday to us! I was looking through the past posts of this blog and found much of it still relevant today. There were some older video posts where the videos are no longer available on youtube, those were deleted.

I continue to look for subjects to blog about while keeping the subject matter pertinent to broadcast engineering or some aspect of radio in general.  With so many things going on, this can be hard to do.

Here are a few stats:

  • Average daily page views: 400
  • Average unique visitors, daily: 240
  • Average returning visitors, daily: 37
  • RSS subscribers: 73
  • Total posts: 323
  • Total comments: 911
  • Total $pam comments: 52,403
  • The average number of comments per post: 2.8
  • The average number of $pam comments per post: 162

This brings me to this; I use an aggressive $pam filter.  There is no way that I would be able to keep up with the number of junk comments received otherwise.  If you have posted a legitimate comment and it doesn’t show up after a period of time, e-mail me and I’ll look into it.  Chances are very good that some legitimate comments have been deleted by the $pam filter, for which I apologize.

Many of my unique visitors come from Google searches which is strange considering its page rank is 0/10.

I continue to enjoy blogging about the everyday life of a broadcast engineer and thank all of my readers and subscribers for their interest.  It is entertaining and enlightening to read all of your comments and e-mails.  For as long as there is interest, the writing project will proceed.

Longwave Radio, Atlantic 252, Ireland

We don’t have any long-wave stations in this country, other than the government’s failed attempt at using long-wave (WGU-20) for emergency communications in the 1970s and 80s. In Europe, Longwave continues to be used, mainly because of its excellent ground wave propagation can cover large distances without fading or interference.  Several have closed in recent years due to the expense of maintaining tall radio towers and higher-quality programming sources.

This is a video of the transmitter site for Atlantic 252 in Ireland.  Atlantic 252 went defunct in 2001, however, the frequency is still in use by RTE radio 1.

500KW is quite a bit of power. The antenna mast is 248 meters, or 813 feet tall. Interestingly, RTE discontinued service on MW (AKA AM broadcast or standard broadcast) but left this signal on the air. Reportedly, this station has less power but better coverage.

VOA to end HF broadcasting

Several places have reported that The Voice of America will sunset its shortwave broadcasts in the not-too-distant future. Boing Boing reported yesterday, based on a paper titled “Broadcast Board of Governors 2010-2012 BBG Technology Strategic Plan and BBG Technology Update – 2009” received via FOIA last January.

The 2009 study notes that the weekly audience for radio is 101.9 million listeners, TV is 81.5 million, and the Internet is 2.4 million weekly listeners.  I don’t know how much that has changed in the last two years, but I’d imagine some shift towards the internet has taken place in light of recent shortwave transmitter site closings.

There are several interesting aspects of this report, notably the disparity between what is termed “Classic Engineering” and “Classic IT” fields.  This is the concept that radio engineers toil on RF and transmitters, while the IT guys work with computers.

As the dependence on shortwave continues to wane and the distribution focus shifts to third party operations, satellite and other direct-to-consumer methodologies, the skill sets of some engineering personnel become less and less relevant to the agency.

This issue is further compounded by the relatively difficult transition from a traditional RF, antenna, transmitter design, and maintenance knowledge base to the technologies involved in digital satellite and IP-based networking systems.

Perhaps that is how it is done in government circles, but I have found in the private sector, most radio engineers know at least the computer automation systems that run the stations.  Of course, everyone has preferences and we tend to gravitate toward things we like to do, especially in a field as diverse as broadcast engineering.  When I was in the military, somebody posted the “Eleven Rules of Success.”  The only one that I can remember now is this: “Pick the thing that you hate and become proficient at it.”

In order to stay relevant, broadcast engineers have to keep up with the technology while remaining proficient with RF and audio skills.  Computers and automation programs are not terribly hard to understand, but each one is different and operates differently.  Most, if not all automation companies offer some type of training, which is fine.  Nothing can beat hands-on installation and troubleshooting for learning the important details, however.

The report also mentions that morale is an issue for several reasons.  First, it is noted that:

Despite several recent high profile station closings, the organization continues to employ shortwave as the most important transmission mechanism to many of the target areas around the globe. Often surge activities are enabled byvadditional shortwave transmissions that end up as an integral part of the ongoing schedule. Effectively, this diminution of transmission resources accompanied by no reduction or even an increase of reliance on this transmission methodology creates overburdened schedules and often the deployment of less than optimal assets for transmission into target areas.

This additional operational burden likely extends to other disciplines within the agency where programming staff must expend substantial additional effort to produce or adapt content for a multiplicity of transmission methods.

In essence, the decision process for station closing does not appear to follow an overt decision and stated plan to reduce shortwave usage.

That is known as the “more with less” paradox.  In the private sector, more with less has been going great guns since the first loosening of the FCC’s ownership rules in 1994.  For those that are used to working in optimum conditions, anything less is a shock to the system.

The issue of low morale is palpable and often present in conversations that address historical perspectives on a particular station closing, transfer of technologies around the network and any other such topics. Precipitated by the long periods of employment that are relatively standard in the Engineering area and perfectly understandable, this grieving process is a natural consequence of the pride involved in creating a state-of-the-art technical facility only to see it being dissected piece by piece as technology continues its relentless creative destruction.

An interesting statement and it shines a light on several things heretofore unsaid in broadcast engineering.  We love our transmitters, as strange as that may seem.  We love our towers and antennas.  Parting with something that has become an integral part of our working environment is difficult, to say the least.  Watching something be signed off for the last time and then hauled to the scrap heap is very disheartening, especially if there is no replacement.

On the IT side, things are not so good either.  The main concern is the infrastructure of the IT backbone.  Several deficiencies are noted in the cabling and router; the cabling is in serious disarray and there is only one router for the facility.  There is also other problems noted with personnel and lack of project management experience and/or IT department goals.

Overall, moving into new media fields makes sense.  There are, however, many places where new media is unknown or at best, mostly unavailable.  Moving content delivery from over-the-air broadcast to IP-based distribution may be far less expensive to operate, that is true.  It is also far more susceptible to being disrupted by accident or design.  In those areas where the internet is spotty, shortwave radios are abundant and relied upon.  If the VOA is not on the air, then some other station will be.
