Another small market build out

Finishing up another studio build out in an unrated market. There are some engineers who think that small market work is beneath them. That is fine with me, I enjoy it.  Once again, creating a nice, functional, modern facility while not breaking the bank poses some challenges.   I like to take sort of a minimalist simple approach while not compromising good engineering practice.  Another challenge is rebuilding an existing facility.  Each studio needed to be demoed one at a time with the stations playing hop scotch from studio to studio around the work.  There were four studios total plus the rack room.  There were also several other renovations going on at the same time as this project.

Looking at the overall facility, the client decided that one studio would be the main room where multiple guests could be seated, etc.  The other rooms would have guest microphones, but they are smaller rooms and limited to one guest each.  The smaller rooms have AudioArts Air4 consoles while the main studio has an R-55e.

The main studio had existing studio furniture that was in reasonable shape so we decided to reuse it.  While we had the studio ripped apart, the paint and carpet where updated.  The main microphone is an Electrovoice RE-20, the guest mics are Heil PR-20UT which are inexpensive and have excellent characteristics for a dynamic microphone.  Since this faces a fairly busy street, I put in some very basic DBX 286S mic processors with a little bit of downward expansion.  Adobe Audition is used for production.  I have also used Audacity which is available in both Windows and Linux flavors.  Acoustical wall treatments are coming soon.

The counter tops in the smaller studios were traded out with a local kitchen supply company.  We used Middle Atlantic BRK-12-22 racks with castors on them to install a limited amount of rack equipment.  Each one of these studios is nearly identical; a AudioArts Air4 console with JBL powered monitors.  The microphones in these studios are Heil PR-20UT with console supplied mic preamps.  These studios are used for WSRK, WDOS, WBKT and WKXZ.  All studios are off line when in automation, which means each can be used for production and other purposes.

We started the TOC from scratch. This area was occupied by a bunch of empty file cabinets previously. The original equipment racks where in Studio A.

A riser was installed from the racks straight up to the roof for the STL, monitor antenna and satellite dish transmission lines.  Everything is grounded with a star grounding system connected to the main building ground which consists of driven ground rods and the water main.  The STLs have Polyphaser IS-PT50HN lightning protection devices installed.

The racks are Middle Atlantic MRK 4031.  Since this building was built sometime in the mid 1800’s, the floors are a bit uneven (along with almost everything else), so a fair amount of shimming and leveling was needed to get these units bolted together.

Racks and equipment

Each rack has its own UPS in the bottom and they are all on separate breakers.

A manual transfer switch controls a dedicated electrical sub panel.  All of the racks and studios are powered from this sub panel.  Below the transfer switch is a NEMA L14-30 twist lock male receptacle for generator connections.

The total load about 18 amps.  The station is looking to trade out some generators for various transmitter sites.  I suggested that they get a couple of the portable Honda inverter generators, which are very good have excellent power regulation, frequency stabilization and fuel economy.

The existing Scott’s Studio 32 system was updated with new computers.  This is an interim step until a new automation system can be installed next year.  Each station has it’s own BT 8.2ss switcher which can select any studio to go on the air with.  That flexibility makes moving from studio to studio easy.  It also allows for all the stations to be simulcast, which is handy in the event of an emergency.

Punch blocks are mounted on plywood attached to the back wall.  We left extra space for a new phone system.

The EAS monitor assignments are met with roof top yagi antennas.  I like drawings and diagrams, as the saying goes, a picture is worth a thousand words.  This is an image I created on Google Maps using the transmitter site coordinates for each of the EAS monitoring assignments.  That gives me good local aiming points for the various antennas needed.

Other drawings include a floor plan and block diagrams for each station.  I have a Viso template that I use for these.  I find that having these diagrams on hand in a book is very helpful in the event that somebody else needs to go to this station to work on things.

Finally, the wiring documentation which shows where each wire originates and terminates. Again, if I am not available and somebody else needs to do work here, this is very helpful. All the studios are laid out the same, so figure out one and then the rest falls into place.

There is still a little bit of clean up left and some old equipment to get rid of.  Otherwise, it’s a wrap.

Gone and apparently forgotten

Can a 50,000 watt AM station disappear from the airwaves and no one notice?

The answer is yes, if you live in the Albany, NY area.  WDCD, 1540 KHz, (formerly WPTR) has surrendered its license to the FCC last Friday, September 28, 2018.  Seventy years on the air and quite the legacy as a Top-40 station in the 60’s and 70’s.

Unfortunately, the station had fallen on hard times the last few years, being silent twice for long stretches of time.  In the end, I suppose it was simply time to pull the plug.

This was my first CE gig in the early 1990’s.  What I remember was, I had a lot of fun working there.

So long and thanks for the memories.

 

I almost hate to say anything, but

We have this certain transmitter which has been on the same tube since June 6, 2001.  Come to think of it, the transmitter itself has been on the air for the same amount of time without failure.  A testament to its designer…

According to my calculations, that is 151,691 hours or 17 years 3 months and 22 days.  The tube is the original EMIAC 4CX15000A that came with the transmitter.

I am a little nervous about turning it off to clean the cabinet.

We have a spare on the shelf for the eventual replacement of this tube, but I really want to see how long this thing will last.  This is also one of the last tube transmitters we have in main service.  There are several backup tube transmitters still around.

Interesting piece on WEQX

I found this video on YouTube about WEQX, Manchester, Vermont.  WEQX is a class B FM station with its tower located on Mount Equinox.  This gives the station a huge signal with a HAAT of 759 meters and 1,250 watts of power.  It comes in well south of Albany and while I am in the Albany area, I enjoy listening to it.

This piece is by CGTN, which one wonders how they ended up in Manchester, VT of all places.

The information below the video is also an interesting read. In part it goes into corporate ownership of radio in the US, stating:

In 1983, 90 percent of U.S. media was controlled by 50 corporations. Today, just six corporations control that 90 percent… Among the 10% (of radio stations) currently not controlled by those six corporations is an alternative rock station in the Green Mountains of Vermont.

That is misleading.  The “six corporations” they are referring to dates back an article published several years ago.  They are; Time Warner, Walt Disney, Viacom, News Corp, CBS and NBC/Universal.  As of this writing, none of those companies listed owns any radio stations.  Further, the media scene in general has become much more fragmented with the advent and greater acceptance of things like Pod Casting, YouTube and other social media.

There are three big radio station owners, which together own 1,613 radio stations. That represents approximately 14% of the licensed commercial AM and FM stations in the US. There are several medium sized owners; Entercom (237), Salem (118), Saga (108), Midwest (75), Forever (69), Beasley (63) and so on.  While iHeart (851), Cumulus (442),  and Townsquare (320) influence the way other station owners operate, by and large, the majority of radio stations in this country are still owned by small business owners.  Stations that are keeping it local continue to be noticed and hopefully rewarded with a successful business.

WEQX is certainly a unique station and it always has been.  In the late 90’s and early 00’s, I did some work for them at various times.  It was always fun and I enjoyed it.

The Answer to Ailing Copper

I don’t know how things are in your neck of the woods, but here in the Northeastern US, our old copper TELCO networks are on their way out.  This is a problem for broadcasters who still rely on POTS lines (Plain Old Telephone Service) for transmitter remote controls, studio hot lines, etc.  The vast majority of my transmitter site access is through dial up remote controls.  There are a few locations that have web based remote controls, but to be honest; the phone part of my smart phone still gets a lot of use.  There are several locations where the old copper is just failing outright and not through a lack of effort by the repair techs.  Generally, the copper pairs get wet and develop a loud hum, which makes the remote control unit either hang up or become unresponsive to touch tone commands.

The best course of action is to get some type of VOIP line installed.  Here is the rub; many transmitter sites are nowhere near a cable system.  Several times, I have contacted the cable company to see if they will provide a VOIP phone line at a certain site.  The response is usually; sure, we can do that!  However, it will cost  you (insert some ridiculous amount of money) to extend the cable to your transmitter site.

LAN extensions to the transmitter site are a useful for a number of reasons.  More and more transmitters are equipped with web interfaces as are processors, UPSs, transmitter remote controls, security cameras,  etc.  LAN extensions can also be used for backup audio in case of STL failure.  Finally,  an inexpensive ATA (Analog Telephone Adaptor) and DID line can replace a POTS line for a lot less money.  One example; voip.ms has the following plans as of this writing:

Plan type Per month per DID number (USD) Incoming call rate (USD) per minute Outgoing call rate (USD) per minute
Per minute $0.85 $0.01 (USA) $0.009
Unlimited $4.25 $0.00 $0.009
Toll Free (800) $0.99 $0.019 $0.009

Any of those plans surely beats the standard TELCO rate of $40-50 per month per line.

Design criteria for a wireless LAN system needs to take into account bandwidth, latency and reliability.  Each VOIP phone call takes anywhere from 28-87 Kbps depending on the protocol being used.  If the wireless LAN is being used for other things such as back up STL service, access to various GUI’s, etc then the total bandwidth of all those services need to be considered as well.  Do not forget ethernet broadcast traffic such as DHCP requests, ARP, SMB, etc which can also take up a fair amount of bandwidth.

For LAN extensions, I have been using a variety of equipment.  The older Moseley 900 MHz LAN links still work, but are slow in general.  The Ubiquiti gear has proven to be both inexpensive yet reliable, a rarity to be sure.  There are several links to various transmitter sites running on various types of Ubiquiti gear, usually without problem.  One simply needs to remember to log into the web interface once in a while and make sure that both ends have all the firmware updates installed.  They are cheap enough that a couple of spares can be kept on the shelf.

The following diagram shows how I replaced all of the copper pots lines at various transmitter sites with VOIP:

The main studio location has the gateway to the outside world. This system is on a separate subnet from the automation and office networks. From that location a point-to-multipoint system connects to the three closest transmitter sites.  This setup uses the Ubiquiti Rocket M5’s with various antenna configurations.  Then, from one FM transmitter site, there is an existing 5.8 GHz path to another set of transmitter sites.  This uses Cambium PTP-250s.

The next hop rides on the STL system, using Motorola Canopy 900 MHz radios and Microwave Filter Company #18486 dilpexers.  These are long paths and the 900 MHz systems work well enough for this purpose.  The main cost savings comes from reusing the existing STL system antennas which negates the cost of tower crews to put up new antennas and or rent on the tower for another antenna.

There is a smaller sub system many miles away that is connected to the outside world through the cable company at the AM transmitter site.  Unfortunately, due to the distances between the main studio and those three stations, there was no line of site shots to these sites available on any frequency.

When installing the 5.8 GHz systems, I made sure to use the UV rated, shielded cable, shielded RJ-45 connectors and Lightning Protection Units (LPUs).  Short cuts taken when installing this equipment eventually come back in the form of downed links and radio heads destroyed by lightning.

Regardless, I was able to eliminate seven POTS phone lines plus extended dial tone service to two sites that previously did not have it before.  In addition to that, all of the transmitter sites now have Internet access, which can be useful for other reasons.  All in all, the cost savings is about $310.00 per month or $3,720.00 per year.

WWV – The Tick!

As a former Coast Guard Radio operator who spent many minutes synchronizing clocks, I find this pretty funny:

The funding for WWV may be cut out of this years budget or next.  Take a few minutes on 5, 10 or 15 MHz to reminisce.  Then turn that thing off, it gets annoying after a while.

A tale of five signals

I am currently finishing an interesting project involving putting up two translators on a diplexed AM tower which also holds a mobile phone/data tenant as well.  All-in-all, this seems to be a very efficient use of vertical real estate.

WMML WENU tower, Glens Falls, NY

WMML WENU tower, Glens Falls, NY

The AM stations are WMML and WENU in Glens Falls, NY.  The AM stations are diplexed using a Phasetek diplexor/ATU.

The translators are W250CC and W245DA which are using a NICOM BKG-77/2 two bay 3/4 wave spaced antenna mounted at 53 meters AGL.  The translators use a Shively 2640-04/2 filter/diplexor which as a broad band input port in addition to the translator input ports.  Since these translator signals are only 1 MHz apart, the higher power Shively filter was installed because it has better rejection characteristics.  The broadband input port allows the NICOM antenna to be used as a back up for any of the three FM stations; WKBE 107.1, WNYQ 101.7, or WFFG 100.3.  Two transmitter sites for those stations are mountain top locations which are very difficult to get to in the winter time.  Having a backup site available takes some of the pressure off during storms or other emergencies.

Shively 2640 -04/2 filter for W250CC and W245DA

The NICOM FM antenna was mounted on the tower when W250CC went on the air in October of 2016.  When it was installed, the base impedances for both AM stations were measured.  For some reason, WENU 1410 KHz seems to be more sensitive to any changes on the tower, thus the WENU ATU needed a slight touch up.  When working on diplexed AM systems, it is also important to make sure that both trap filters, which are parallel resonant LC circuits, are tuned for maximum rejection of the other signal.  During this particular installation, nothing was added to the tower and no change in the base impedance for either station was noted.

As a condition of the construction permit, measurement of spurious emissions of all stations sharing the common antenna needed to be completed to ensure compliance with FCC 73.317(b) and 73.317(d).  I made careful measurements of the potential intermod products between the two translator frequencies.  This measurement was completed with my TTI PSA6005 spectrum analyzer.

The primary concern here is mixing products between the two transmitters. Both transmitter are BW TXT-600 with low pass filters before the output connector. There are three frequencies of interest;

  1. (F1 – F2) + F1 or (97.9 MHz – 96.9 MHz ) + 97.9 MHz = 98.9 MHz
  2. F2 – (F1 – F2) or 96.9 MHz – (97.9 MHz – 96.9 MHz) = 95.9 MHz
  3. F2 + F1 or 97.9 MHz + 96.9 MHz = 194.8 MHz

That, plus harmonic measurements out to seven or eight harmonics of the fundamental frequency should be enough to demonstrate compliance with FCC out of band emissions standards. Being that this site has LTE carriers, it is very important to measure the harmonics in those bands. Mobil data systems often use receiver pre-amps, which can amplify harmonics from the FM band and make them look out of compliance. Having a base set of reading to fall back on is always the best course in case the “out of tolerance” condition gets report to the FCC.

Measurements on these frequencies must meet the emissions standards outlined in FCC 73.317 (d), which states:

Any emission appearing on a frequency removed from the carrier by more than 600 kHz must be attenuated at least 43 + 10 Log10 (Power, in watts) dB below the level of the unmodulated carrier, or 80 dB, whichever is the lesser attenuation.

Harmonic frequencies to be measured:

Harmonics for 96.9 MHz fundamental Harmonics for 97.9 MHz fundamental Comments
193.8 195.8
290.7 293.7
387.6 391.6
484.5 489.5
581.4 587.4
678.3* 685.3* US LTE Band 71
775.2* 783.2* US LTE Band 5
872.1* 881.1* US LTE Band 5
969.0 979.0

*Frequencies that fall within the mobile data LTE bands. Traces where recorded and saved for these frequencies.

All of that information, once compiled is attached to the FCC form 350-FM, which, once filed grants Program Test Authority.

GatesAir FLX-40 one year in

I was at the WEBE transmitter site recently and took the time to look over transmitter we installed last year:

GatesAir FLX-40 transmitter, WEBE Bridgeport, CT

GatesAir FLX-40 transmitter, WEBE Bridgeport, CT

Overall, I would say that this transmitter has been very reliable.  We had to install a UPS for the exciter and HD Radio exporter, but that is not a big deal. During the first power outage, the exciter went dark first. It took longer for the transmitter controller board to lose power, in the interim the controller turned the transmitter power all the way up. When the generator came on line 10 seconds later, the transmitter returned to operation at 41.5 KW. This, in turn, caused one of the other field engineers to freak out and nearly lose his mind (stay away from the brown acid, FYI).

I installed the UPS a few days later.

WEBE TPO 35.3 KW with HD Radio carriers on

WEBE TPO 35.3 KW with HD Radio carriers on

Transmitter power output is 35.3 KW, which is getting into the semi-serious range. The reflected power goes up when it gets warm out and goes down in colder weather.  Over the winter, it was running about 50 watts.  Even at 138 watts, that represents 0.004% reflected power. The TPO forward goes to the 6 bay, 1/2 wave spaced antenna side mounted, 470 feet (143 meters) AGL. The station covers pretty well.

WEBE Pump station

WEBE Pump station, pump is running 2/3 speed and fans are running at about 1/2 speed

Overall, I would give the liquid cooling system an A grade. The transmitter still dumps a fair amount of heat into the room from the RF combiners and PA power supplies. Most of the heat, however, ends up outdoors. Previously, we had two Bard 5 ton AC units running almost full time. Now, only one AC unit cycles on and off except for the hottest days of the year. Outside temperature when this picture was taken was 81 degrees F (27.2 C).

Next year, we will have to send a sample of the coolant off to be analyzed.

I have had good experiences with the GatesAir FLX/FAX series transmitters. I would recommend this to a friend.

Status of AM revitalization

It has been about five years since the AM revitalization initiative was first proposed by the FCC and about five years since the first rules changes took place.  Those rules changes included:

  1.  FM translators for AM stations
  2. Allowing stations to use MDCL (Modulation Dependent Carrier Level)
  3. Changing some of the antenna radiation efficiencies requirements
  4. Changing some of the allowable interference towards other stations requirements
  5. Loosening some rules regarding proofs, MOM, night time coverage over city of license, etc

Things that were not addressed:

  1. Receiver quality and technical advances
  2. Ambient noise levels on Medium Frequency (among other) bands
  3. HD Radio or any other digital modulation scheme

Things that were discussed then changed subsequently as a separate initiative:

  1. The main studio rule, which was eliminated for all broadcasting stations

What has been the net effect of these changes?  Has any of this revitalized AM radio?  The net effect has been approximately more of the same.  There have been many stations that have applied for and received licenses for FM translators.  Those stations, in most cases that I am aware of, receive some benefit of extra revenue because of this.  Stations with carrier power levels of 10-50 KW have taken advantage of MDCL technology to save some money on their electric bill.  Nothing wrong with that.

For stations that use a directional antenna, proofs of performance and other DA matters with the FCC have become slightly easier.  Medium Frequency (MF) directional antennas are very large, require a lot of land, are expensive to build, license and maintain.  I know of several stations which have downgraded from a class B station with a directional antenna to a class D station with a single tower and greatly reduced night time power.   Those downgraded stations certainly benefit from an FM translator.

I have heard from more than one AM station owner who says after four years, they are going to “turn in their AM license and just keep the FM.”  I am sure that they are not informed regarding translator rules.  Perhaps, however, the FCC will allow this in the future; a sort of back door commercial low power FM station classification.

The AM band zenith occurred in November of 1991, when there where 4990 licensed AM stations in the United States.  As of June 30, 2018, the total stands at 4633.  That is a decline of 357 stations.  There are currently 90 AM stations listed as silent.  That represents a decline of approximately 9 percent or less than 1/2 of one percent per year.

The last number of AM stations actually transmitting HD Radio that I found was approximately 110, which differs from the iBiquity (and FCC) number of 240.  The FCC data base includes stations which are currently dark, or stations which where transmitting HD Radio at one time but have since turned it off.  Either way, it is a small percentage of licensed stations.  As of this time, AM HD Radio appears to be a non-starter.  In other parts of the world, Medium Frequency DRM seems to be doing well.  The difference seems to be that the DRM operation is all digital and the digital carriers have a much higher power level than that of the hybrid AM HD Radio being used here.

Of those 4633 standard broadcast stations, approximately 260 belong to iHeart radio, Cumulus owns approximately 120 and Townsquare owns approximately 80.   That accounts for 460 stations.  The remaining 4000 or so stations currently on the air are owned by medium sized corporations or individual owners.  The reason for the distinction; I have noticed that the large corporate owners tend to concentrate resources and effort on those licenses that will make the best return, e.g. FM stations.  Of course, there are a few exceptions to that trend, often in major markets.

Of those 4000 or so remaining AM stations, most seem to be treading water.  They are making enough money to stay on the air.  There are a few AM stations that are doing remarkably well.  Those are the ones with primarily  local content.  The vast majority of AM stations are running some type of syndicated talk.  News/talk and sports radio are the two most common formats.  Conservative news/talk seems to be the bread and butter.  Liberal news talk has been tried, but none have succeeded.

Last May, the Supreme Court overturned the Professional and Amateur Sports Protection Act of 1992.  That federal law prevented gambling on outcomes of professional and college sports games.  With the overturn of that rule, individual states can now legalize sports betting.  It will be interesting to see what states allow legalized sports gambling and whether that has any effect on the various sports radio formats.  I can see where individuals and odds makers may want to get good inside information regarding team dynamics and so on.  The sports network that can furnish such information may be in a good position to carve out a niche.

Music can and does sound good on AM when it is done correctly.  There is a great misconception that AM fidelity is poor.  That is not necessarily so.  There are a good many AM receivers these days which have much better bandwidth than the previous generation receivers.  I am noticing that car radios in particular sound much better.  Yes, there are still problems with electrical noise and night time interference.  There are still technological improvements that can be made for analog AM on the receiver side.

In summary; the revitalization efforts have benefited some AM stations in some areas.  The truth is, that many AM stations have been let go for so long that there is no saving them.  Other AM stations that are still viable are making a go of it.  In nautical terms; there is six feet of water in the hold, the pumps are working and the ship is not sinking… for now.

WKIP

This was the radio station that I listened to (or rather, my parents listened to) when I was a very young kid.  From this source, things like school closings, weather, lunar landings, news, sports and traffic could be heard.  At one point, there was a guy called the “Traffic Hawk,” (real name Don Foster) who flew in a Cessna 172 east and west over main street in Poughkeepsie advising drivers of any slow downs in the area.  That’s right, Poughkeepsie, New York, population 30,000, had it’s own eye in the sky, broadcasting live from the aircraft overhead.  Actually, I think he also flew up and down South Road (US Route 9) in the vicinity of the IBM plant, which employed quite a few people in those days.

There was also a guy who tried to break the Guinness Book of World Records by staying awake the longest, this happened several times.

For me, it was the school closings.  I hated school with an absolute passion.  Everyday, I would ride the school bus and say a little prayer; “…please God, make it today.  Make the boiler stop working, or the electricity to go out.  Make the kitchen catch on fire or the roof to cave in.  You are a great and mighty God and I don’t ask for much.  Please destroy my school today.”  Alas, God did not seem interested in this.

Anyway, back to the topic at hand.

WKIP first signed on in 1940 with the studios and transmitter located at The Nelson House, 42 Market Street, Poughkeepsie.  That building is long gone and  the location appears to be the parking lot for the Dutchess County Office building.  Being neighbors with some influential guy from Hyde Park made for a nice dedication speech:

It signed on with a power of 250 watts on 1,420 KC on June 6th, 1940. Soon thereafter, it changed frequency to 1,450 KC as a part of the AM band shift brought about by NARBA.

Over the years, the station went through several ownership changes. The first major technical change came in 1961, when the station transmitter site moved to it’s current location, then called Van Wagoner Road, now Tucker Drive. The station increased power to 1,000 Watts and installed a direction antenna for daytime use.  It is one of those rare night time non-directional, day time directional stations.

The directional antenna consists of two towers; tower one is 180 degrees tall (103.4 Meters or 340 feet) with 35 degrees of top loading.  That is used for both the day and night time array.  Tower two is 85 degrees tall (48.8 Meters or 160 feet) and is used only for the daytime array.  This pushes the major lobe of radiation towards the north.  I don’t know the reasoning behind that, but somebody spend a good amount of money to make it so.

Here is a air check from the early 1980’s.  Weather on that day was “Sunny, cloudy, whatever… take your pick.”

Good old Steve Diner.

Today, the station looks like this:

When I was growing up, my cousins lived within walking distance of this. We used to come over than throw rocks at the tower when the station was unmanned on Saturdays and Sundays. At least, I think it was unmanned because no one ever came out and yelled at us.
