Comparison: Over the air listening on FM vs. streaming audio on Android phone

I have had my HTC Android phone for just about a year now, which is enough time to learn the device’s strengths and weaknesses. I have done a fair amount of listening to the audio, watching youtube videos, and playing .mp3’s to give me some idea of the technical quality and operational issues. Like anything else, these are general observations. Some radio station’s streams sound better than others due to the effort those stations put into audio quality.

The listening test was done with a set of Sony earbuds, which sound far better than the small speaker built into the phone. For ease in streaming audio, I used the TuneIn Radio application for Android by TuneIn Inc. For this test, I only listened to FM broadcast stations, both streaming and over the air.

The over-the-air tuner is the stock factory radio in my 1997 Jeep Cherokee. I would rate the radio average in every way. The actual tests were done driving around on interstate highways and other major roadways. There were a few instances where I had to give up on the Android phone due to traffic and driving considerations.

My Android phone has an FM tuner installed in it, however, it is really useless. I get only local stations, and then their audio is all hissy and for the most part unlistenable. The HTC FM tuner uses the headphone wire for an antenna, which may be a part of the problem.

Here is a chart of my observations:

Category evaluated	Analog FM radio	Streaming via Android
Overall Station Selection	Only those stations that can be received	Any station that is listed in TuneIn Radio App*
Almost unlimited, worldwide*	Can press the preset or scan buttons on the radio without taking eyes off the road*	Only those receivable signals limit it to a few well-programmed stations, the rest being garbage
Available formats	Only those stations that can be received	Any station that is listed in TuneIn Radio App*
Ease of use	Varies depending on location, and can be quite annoying, especially in mobile environment. App also occasionally locks up and needs to be restarted	Requires squinting at a small screen and pressing several little boxes to get to the desired station
Annoying commercial avoidance	See above on preset and scan buttons*	Very difficult to change stations quickly
Quality of sound	Good to excellent, depending on the station’s signal strength*	Fair to good, depending on the bit rate and network congestion, some stations sound very good and some can sound very bad
Drop outs	Occasional picket fencing with distant stations, otherwise, non-existent*	Requires data plan with smartphone, some plans cap data amounts, can be fairly expensive
Expense	Free, radio came with the vehicle, no paid data service needed*	Requires data plan with smartphone, some plans cap data amounts can be fairly expensive
Overall enjoyment	Good	Good

*Wins category.

I am having a difficult time assigning the overall enjoyment as well as an overall winner. On the one hand, it was very cool, driving down I-84 in Danbury, CT listening to Howlin’ Wolf on New Orleans’ non-commercial Jazz station, WWOZ. On the other hand, it was a right pain in the ass to get to that point, in rush hour traffic. By the way, WWOZ’s web stream is excellent, audio-wise.

From safety and ease of use, the FM radio in the Jeep wins hands down, I just don’t know how many more times I can listen to the same Led Zeppelin song on i95 (that used to be I-95, frankly I thought Steve Jobs copyrighted the lower case i).

The dropouts were also a concern, mostly taking place in the section of I-84 going through Putnam County, NY. I don’t know if my cell carrier needs to beef up its data coverage in that area, or if there were just a great many users on the network checking their e-mail, etc.

If they could sort out the ease of operation problem and get rid of the dropouts, streaming audio over HTC Android would win hands down.

Media

It dawned on me, earlier today, that the current decline in radio and all traditional media in general, is no coincidence. When the radio consolidations took place ten or so years ago, the first thing that was almost always cut or eliminated was the newsroom. Along with that, local programming in general was reduced or replaced with automation.

This, in turn, leads to a bland, uninformative product that the general public doesn’t really care about.

Local newspapers have all but disappeared too. The remaining ones are owned by one of several large newspaper-holding companies like Gannett, Newscorp, Hearst, and Tribune. In a similar radio scenario, local papers were bought up by these companies, newsroom staff was cut, the quality of content declined, and readership declined accordingly. Rinse, and repeat until the paper is nothing but a shell of its former self, filled with mostly used car ads.

But isn’t the internet the cause of all this? No, the internet and the so-called “new media” are filling a void left by the hollowed-out old media. New media, which often relies on people who may be well-intended, but do not have the training in investigative journalism, often lacks credibility when it really counts. Unfortunately, it is easy to search the internet and find articles that lack any type of referenced source material or have other technical problems that call into question the authenticity of the material. Much of this could be corrected with the right links or posting of original documents to back up the story. This is an often pointed to weakness with internet sources of information. There are, however, some outstanding new media outlets, from some surprising locations.

Media outlets (as well as most other businesses) in this country are mostly controlled by big Wall Street banks. Here is how that works:

Media company A wants to buy some or all of media company B.
They go to a bank to get a loan.
After much negotiating and back and forth, the bank agrees to give A the loan, under certain conditions.
Those conditions include continued performance, annual revenue growth, and periodic audits.
In a buy-or-be-bought world, there is no other alternative for A, but to agree with those conditions.
Media company A now needs continued credit to continue to operate their business, this is what happened during the great consolidation, not only of radio but TV and Newspapers as well.
If and when the conditions of the loan look like they are not being met, the bank sends out its representatives to talk to the owners of media company A.
They “suggest” moves to improve the bottom line, often offering to make concessions if certain conditions are met, such as installing voice tracking and laying off workers or selling properties
Newsrooms are cut first as news is labor intensive and does not make any money.
Slowly, the rest of the staff is reduced or has their pay and hours reduced.

It is thus that the large banksters have gained control of much of the “traditional” media in this country. They have sought to steer the free press into oblivion, substituting, instead, the corporatist media outlets we see today in NBC, ABC, CBS, MSNBC, CNBC, FoxNews, as well as the above-mentioned newspaper holding companies. While skimming over general news items, much of the important news of the day goes unreported. Things like the Fed’s latest round of quantitative easing (QE3), the ever-expanding role of TSA, the unauthorized nature of the Libyan adventure and the possible ties to Goldman Sachs, the continuing nuclear release at Fukushima, FDA approval of GMO seeds, the FCC’s revolving door employees, ever-increasing amounts of police brutality, etc are under-reported or not reported at all.

Why are those particular stories important? Because the implications impact every one of us, only most people don’t know or understand that. Citizens of this country have no idea why things are getting so expensive, why their jobs have disappeared, why their houses are worth less than they paid for them, why the current crop of politicians looks worse than the last crop, why police are dressing like storm troopers and gunning people down in their own homes, etc. It all reminds me of the Pink Floyd song, Sheep:

Harmlessly passing your time in the grassland away
Only dimly aware of a certain unease in the air

We are being fed with little bits of oversimplified, unconnected, and or incomplete information which only fits the narrative the so-called news organization is putting forward. Deviation from the narrative rarely occurs and only under the most unusual circumstances or by accident.

The answer is, of course, to support those independent media outlets that are still around. The independent radio stations, TV stations, and newspapers as well as those online news sources and aggregators that do a good job getting the story out need to stick around. It would also help to increase the number of independent, non-conflicted (interest-wise) sources of information. I would suggest that everyone do a little bit of digging around and find out who, in their own neck of the woods, is an honest source of local news.

If there is not a local independent media outlet, consider starting one. The new LPFM rules are still being worked on, the FCC has promised to speed this along, which means we should see something in the next five years or so. While we wait, consider blogging or teaming up with a group of people to launch an online news site. While I have been blogging for several years, I have learned one very important fact: People love the truth. That is the surest formula for success, tell the truth and back it up with valid sources and documentation. I know many people in the radio news business that, if asked, would be happy to give some pointers on local news gatherings.

One thing is for sure, we can no longer sit around and wait for someone to do something. If we are to change the course of this country, each and every one of us needs to contribute.

EAS/CAP continued

Lots of ink has been spilled about the new CAP (Common Alert Protocol) implementation and what it all means. Since the FCC started the six-month CAP clock ticking on September 30th of last year, they have extended the deadline by six months to September 30, 2011.

The idea of upgrading EAS is a good one. When EAS replaced EBS in 1997 it was supposed to do away with the over-the-air relay system also known as the daisy chain. This was left over from the 1960s CONELRAD system implemented by Kennedy. That replacement never occurred and stations today are still monitoring other broadcasting stations for their EAS alerts. The daisy chain was and still is the source of all EBS and EAS failures.

CAP is supposed to eliminate that weak link by allowing the EAS unit to access government IPAWS message servers directly, allowing FEMA to automatically send out alert messages to designated areas. This has some libertarians in an uproar, as they see government intrusion and taking over privately owned radio stations to broadcast emergency information as a form of tyranny. In as much as the definition of “emergency message” has not been codified by FEMA in any of their information, they may have a point. In the past, the general definition of emergency communications was those that were pertaining to imminent threats to the safety of life and property. According to Executive Order 13407, Public Alert and Warning System, the purpose is to:

…have an effective, reliable, integrated, flexible, and comprehensive system to alert and warn the American people in situations of war, terrorist attack, natural disaster, or other hazards to public safety and well-being…

Which is certainly much broader in scope. How does one define a hazard to “well-being?”

SAGE alerting systems have completely revamped their ENDEC to include CAP 1.2. It uses the internet to connect to IPAWS servers and receive CAP messages. As the SAGE ENDEC owners manual notes, participation in local and state-level alerts is at the discretion of the station management, as regulated by the current version of FCC Part 11. National-level participation is mandatory:

Participation at the national level is mandatory for most broadcasters. You may petition the FCC to become a “Non Participating National” station, but you must still receive and broadcast the EAN code, and then leave the air. These requirements are always evolving, refer to the FCC rules, in particular CFR 47 Part 11 for details.

Oftentimes, it is the local emergencies that are the greatest and most immediate threats to human life; the tornado, the tsunami, etc. Those are the most pressing threats, not the national-level alerts, which were implemented in the 1960s to warn of a major attack from a foreign country, something not very likely these days.

Further, the internet has proved to be less than reliable when trouble occurs. During the terrorist attacks on 9/11/2001, dial tone, cellphone, and internet service for much of lower Manhattan were disrupted because the TELCO facilities were in the buildings that were destroyed. Most internet services rely on wired or fiber optic services provided by TELCO or cable companies, which can be affected by power outages, damaged infrastructure, and so on, which would likely occur in a major emergency.

It does not seem to be the most robust method for the distribution of emergency messages.

Nice work, if you can get it

I have been to many, many transmitter sites. They range from mountaintop sites in NY and VT to flat fields with tall towers in Florida to coastal or wetlands AM sites. One site in Massachusetts was located in a state park near Westover AFB. It was formerly the microwave relay site for the Northeast Command and Control bunker, now reused as an FM site for WRNX, Amherst. Access to that site required walking about a mile and a half on a hiking trail, often carrying things like a shop vac, garbage bags, or other stuff. Walking in the woods carrying a shop vac will get you some funny looks by fellow hikers.

Yesterday was my Bridgeport, CT day and I took the time to head out to the WICC transmitter site. There are two ways to get there, one can call the Bridgeport harbor master or harbor police and catch a ride via boat, which is fun. Or one can walk down the beach from the long beach parking lot. If it is not an emergency or nighttime access, I like to walk down the beach. It is about one mile either way. I normally bring my backpack with some basic tools, water, and a sandwich.

I have been working with another engineer who complains about this.

Now that the cottages are gone, it is a very pleasant walk.

This Osprey apparently didn’t get the memo: Radio towers are the arch-enemy of birds, actually sitting on one and using it as a good place to scout for lunch is akin to sleeping with the enemy.

I wouldn’t want to hike down this strand of beach at night or in a thunderstorm, but on a nice day, it is a pleasant stroll. There are far worse transmitter site access problems. It is a pain if any equipment needs to be taken in or out, that requires some special equipment.
