Deployable Aerial Communications Architecture
Today the FCC release a Notice of Inquiry (NOI) regarding Deployable Aerial Communications Architecture (DACA). In a nutshell, this technology involves deploying a light aircraft containing communications equipment over a disaster area to provide emergency communications. Those familiar with mobile wireless will recognize this as somewhat analogous to a COW (cellsite on wheels), and the military has been using similar technology for years.
A whitepaper on DACA describes the potential for this technology:
The DACA vision for disasters involves an aerial capability that is deployable within the first 12-18 hours after a catastrophic event to temporarily restore critical communications, including broadband, for a period of 72-96 hours. This capability would be useful in situations where the power grid may be inoperable for 5-7 days, depleting back-up power supplies and resulting in an almost complete failure of landline, cellular, land mobile radio, broadcast, and cable transmissions, as well as Wi-Fi and Internet services. In such circumstances, access roads and bridges may be impassable, preventing communications repair crews and fuel suppliers for generators from entering the area. If DACA systems were available, users on the ground could continue to rely on their day-to-day communications devices in a transparent manner.
While DACA technology does not involve amateur radio, nor does amateur radio have a horse in this race, amateurs may find DACA technology interesting, as the recent interest in unmanned balloon experiments with amateur radio payloads would suggest. The FCC in the NOI is seeking comment from industry on logistical, regulatory, and technological questions. I imagine it will be several years before we see DACA technology ready for prime time and probably only in major metropolitan areas.

What Would You Say?
In July I’m giving a 45 minute talk on amateur radio to a local neighborhood group that restored and maintains an old historic schoolhouse down the road from my QTH. I plan on bringing my FT-897 and throwing a dipole up in the yard so I can tune around the bands and maybe even whip up a phone QSO. (It sure would be nice if 20 was open to Europe.) I’m going to avoid “death by PowerPoint” and just work off of some simple bulletpoints.
So, any suggestions on what to talk about? What would you definitely not talk about? Any tips from seasoned speakers on things to wow the audience with?

The Menta
MakerShed announced a new product that will probably appeal to radio artisans who like to build little rigs. It’s the Menta, a smaller version of the Arduino which fits nicely in the venerable Altoids tin.
Get a few 2N2222s, some toroids, resistors, and a crystal soldered on the prototyping area, then burn some CW keyer software on the Arduino and voila, you got a nice little QRP rig.

Supporting CW
RSGB had this puzzling note in its recent news script:
Some say that CW has been made obsolete by modern digimodes, which work well in conditions far too poor for the older mode. Now that Morse is no longer used in commercial radio traffic, the RSGB confirms that it would fight any moves to prohibit CW on amateur bands. The Society recognises that Morse gives much pleasure to thousands of operators, and will continue to support its use.
The blurb doesn’t cite any specific threats. To use a quote never said by, but attributed to Jerry Seinfeld, “Who are these people?“
I’ve said before that there are people saying there are people saying that CW is dying, but I have yet to find anyone saying CW is dying. Much like American politics, we tend to get our panties in a bunch making up things to be outraged over and threats to be worried about. No radio amateur who has been licensed more than a week would seriously propose to outlaw CW operation. Any amateur who does is likely insane or doesn’t have the capacity to garner support of anyone from amateurs to government officials.
Perhaps I’m reading more into the RSGB statement and giving it more time than it deserves, but my guess is RSGB suffers from one of the thorns that has been in the side of ARRL here in the States. People make accusations that the organization doesn’t support the code, in order to increase the number of licensed amateurs and fill its coffers with more memberships. The people who make such nonsense accusations are still upset with the elimination of the code test or just dislike the organization and look for whatever means to criticize it. To this day I still hear people claim ARRL doesn’t support CW, despite petitioning the FCC for a 5 WPM test for the Extra class test and running code practice and bulletin broadcasts every weekday. Myths are hard to replace with facts.

HRD
HRD Software, LLC has released version 5.11a of Ham Radio Deluxe, the first version since their acquisition of HRD from Simon Brown, HB9DRV. The release appears to be a minor update with the most notable changes being cosmetic updates to splash screens, showing the new ownership of the product.
As many predicted at the time of the acquisition, the next version of HRD, 6.0, will be a pay-only product. The 5.x version will continue to be free and will have bug fixes released for an unidentified amount of time. Version 6.0 will be released at the Dayton Hamvention, but customers can receive a $20 discount for the product by subscribing to HRD support for $59.95 prior to Dayton. At Dayton and afterwards the price for 6.0 will be $79.95. That is a one year subscription. Subsequent support subscription renewals are $39.95 for two years of support. The software doesn’t expire and can continue to be used after support expiration, however users must have a subscription in order to get software updates.
Personally I think Ham Radio Deluxe is worth this price. As I’ve mentioned in previous posts, I think it’s the best amateur radio logging software ever written (though in a sea of outdated and badly designed sophomoric applications, the bar is often set low). But considering how good version 5.x is, it may take quite awhile for people to actually want or need to upgrade. Unless the trial version of 6.0 really knocks my socks off, I’m going to wait until perhaps version 6.1 or 6.2 to consider upgrading.

CQ CLASSICAL MUSICIANS DE NØIP
How many of you ham radio operators are also classical musicians? (I’m using “classical” loosely here, the way NPR does — not merely referring to the classical period per se, but broadly referring to all music of higher artistic expression.) I’ve always been intrigued by this kind of simultaneous development of artistic ability and scientific/technical ability. I’ve long heard that the two complement one another nicely, e.g. I’ve heard that musicians make better programmers.
Right now I’m working hard with the Exultate Festival Choir and Orchestra to get ready for an upcoming performance of The Messiah by George Frideric Handel. Ham Radio has taken a back seat in my life during this seven-week project (as well it should, if we have our priorities straight). Yesterday’s rehearsal in the Twin Cities was exhilarating, and once again proved that the 2 1/2 hour drive to get there is definitely worth it. Dr. Tom Rossin is an outstanding conductor, and the choir is so good I have to pinch myself sometimes to see if my place there in the bass section isn’t just a dream. (If any of you happen to be in the Twin Cities on the weekend of March 9-11 and would like to hear The Messiah in its entirety, send me an email and I’ll email you a coupon that will get you two tickets for the price of one.)
Music was part of my life as a boy before I became a ham, but it didn’t blossom until 13 years ago at the age of 31. That was when my brother Tom (NØBSY) got me involved in a cappella shape-note singing from The Sacred Harp. This taught me how to sing parts; without it I could never have gotten into choral singing the way I have. My first choral work was with Exultate, singing Bach’s Mass in B-Minor, followed by Brahms’ German Requiem (in Rutter’s English translation). Since then I’ve been involved in a small choir here in the church, too. All of this has been a huge surprise to me. Up until I was 31 years old I was afraid to sing in front of other people, and I couldn’t sing parts if my life depended on it! So if any of you think you can’t sing, think twice — you might be surprised at what has been lying dormant in those vocal chords of yours, just waiting for the proper nudge to burst forth into beautiful song.
I see Tyler Pattison, N7TFP, is not only an accomplished ham radio operator but an accomplished musician. Along with his excellent tutorials for ham radio operators, Tyler has also posted a video of his performance of Charles-Marie Widor’s Toccata in F from Symphony No. 5. In this video you can see the organ from Tyler’s perspective, not only as a musician but as an electrical engineer. He is bringing both sides of his brain to bear upon the magnificent task of rebuilding and upgrading this organ — and then making beautiful music on it.
How many others like Tyler and myself are out there? If you are a musician and an amateur radio operator, what do you think? Has one influenced the other in your life? How?
