MERCENARY.COM Letter from Bob

When the Mercenary.com property came to us we sent this letter to the old Mercenary customers, many of whom we knew well.

It has been over ten years since Soundwave Research started designing sensors, transducers, antennas, mics, pickups and other things related to the art and science of sound.

Huckleberry era Closed

The closing of Huckleberry Music/Mercenary Audio was much discussed, but not much mention has been made of the motifs, artwork, advertising ideas and trademarks that make the Mercenary Audio brand a good fit for all kinds of merchandise and services today.  I tried to find an old ad that was not specific to any particular product and came up with this one from way back: "More signal  Less noise"tm is something we always agreed with.

The 1960's style of this ad appeals to me. It is, perhaps, visually reminiscent of old TWA posters set to the tune of Tom Waits' "Prices Prices".  Enjoy the humor and the message!

Soundwave Research owns and uses Mercenary, Mercenary Audio, Mercenary Wireless on products and services relating to a wide variety of products and works with sister division http://www.rfvenue.com to serve wireless needs in venues, churches, theaters and convention centers.

John Cate wins Good Song Award. 2nd GSA issues for "You Should've Warned Me"

Ashland, MA June 4, 2013:  Soundwave Research has awarded its second Good Song Award to recording artist John Cate for his song "You Should've Warned Me".  The Good Song Award criteria was met after many months of listening and scanning for that "Good Song". An unspecified, potentially secret award is given to each recipient of the Award, which has previous issued for only one other "Good Song" to date.

Dowload this album - The Sausage Factory


Klezmer, meets Tin Hat Trio meets Beck meets Bonzo Dog meets Eminem meets Donald Fagen meets Basement Jaxx meets Uncle Meat, ground, salted and extruded by the mind of Sean, known for the El Diablo song, among other creative controversies. This one an encyclopedia of motifs, encased like knockwurst, the kind that is still crackly and sublime, but more complicated than that.  Throw away the flaccid rock idioms and leave behind the indie dirges: Instead listen to this "fun record".  The MOBA-like album art is a plus, and tells you nothing about what's inside.  Just like sausage.



SEAN ELDON
THE SAUSAGE FACTORY
Former guitarist of The Arrogant Sons of Bitches (and brief keyboardist of Bomb the Music Industry!), Sean Eldon wanders out into the pop landscape and hitting all the good stuff. Written and recorded in little over a month, The Sausage Factory is an immediate and incredibly fun record to listen to. For fans of Squeeze, Dismemberment Plan, Elvis Costello, The Supremes and other good things.

Diversity Fin Antenna solves longstanding problems with indoor wireless

The enthusiastic response and fast sales of the Diversity Fin Antenna have been gratifying, to say the least. Most users appreciate the convenience and performance aspects:

1. Single stand

2. Orthogonal elements virtually eliminate cross polarization nulls.

3. Superior signal constancy within the field of use.

4.Non-critical positioning relative to the stage.

5. Forward biased bidirectional dipole 90 degrees from the plane of the substrate - the dipole is not an omni (see specs here)

6. Uncorrelated orthogonally polarized LPDA with minimal cross coupling.

7. Works with all two branch systems and even with two antenna phased array systems (those that switch phase of two spaced apart antennas to provide a positive signal)

8. Safety. If it falls over, there are no sharp or hard edges to damage equipment or other objects. The corners of the dielectric cover is padded, and the cover doubles as a travel case.

9. Stows by just folding the dipole into the stow position.

10. Price

11. Polarization diversity is rapidly being adopted by telecoms, land mobile systems, urban communication systems and other RF transmission equipment due to its superior signal constancy with virtually no tradeoff  (typically 1 dB) in gain. (see this paper for a good read on why this is)

12. Designed using current Human Factors Design principles by a team with over 4 decades of antenna design experience, and over 30 antenna related patents.

The spectrum should be ours, and it still can be

by Bob Crowley


It’s not hard to find dozens of articles about the impending FCC rulings allowing much wider use of spectrum in the spaces between television broadcast stations. So-called White Spaces are a partial misnomer, as this article in Wired makes the common error of calling WiFi a white space spectrum. It isn’t.  But what is apparent, and correctly mentioned, is that the FCC and others have a naive idea of what the future of spectrum use will afford. Yes, smart cars will need radio communications to control them, of course. But this misses the point of what electromagnetic radiation afforded communications are all about. The ability to transfer large amounts of information through space is unique to EM/radio and it has taken since the late 1800s for technology to be developed that can use it in a more or less automatic fashion, instead of having radio operators find channels and manually switch frequencies.   That’s where we are today, with the basic computer capable of two-way data communication to another computer not too far away, wirelessly.

Free wifi, cellular, for all?

Now for the next step: Long range peer to peer communication, mesh networks they are sometimes called, where your laptop or smartphone jumps to another person’s laptop, and over and over it relays to the final destination. Such use requires bandwidth, and is clearly in the mind of FCC.  Wimax and LTE are other more conventional ideas of hubs and spokes connected to the conventional ISP structure of the internet, but peer-to-peer direct connections are far more delicious to think about, as they bypass the giants such as Verizon and others, at least that’s the idea.

Getting physical

We’ll see in a few years. Meanwhile, the physical layer, the part where a signal goes out into space to be collected somewhere else, will still exist unchanged. No matter what, we can say confidently, the physical part of electromagnetic radiation, propagation and collection cannot be avoided if we are to have wireless communications among us, and that means energy will have to be used, though in small amounts, and that leads to efficient antennas.(or not, as in the case of the most recent iPhone antenna fiasco)

Something has to pick up the signal, and also transmit. Battery life is entirely dependent upon the efficient, non-wasteful radiation of RF energy to the nearby or perhaps not so close connection points that are being installed everywhere.

"Spectrum Omniscience" is a Possibility

One can imagine that no matter where you are, you will have continuous, ubiquitous connectivity via mesh networks.  We will be able to  receive and send information everywhere, all the time, to everyone. There will be dive-in points held by the large carriers and perhaps smaller enterprises too, but the rules of business will change, and if we are lucky, the spectrum will be ours.
