The Siru Innovatios SDR20 multi-touch portable SDR

[Note: this post was originally published on my shortwave radio blog, the SWLing Post.]

Siru-Innovations-SDR20-4

A few weeks ago, at the Four Days In May conference (held alongside the Dayton Hamvention) I met Jarkko Mäkivaara from the Finnish company Siru.

Jarkko was demonstrating the SDR20: a radio that immediately grabbed my attention from across the room. The SDR20 is a fully portable, robust, multi-touch portable SDR transceiver.

Siru-Innovations-SDR20-5

The screen on the SDR20 is as responsive as an iPad and fully developed around SDR functionality. While Jarkko didn’t have an HF signal of any sort inside the hotel convention room, I was able to play with the interface a bit, which I found rather intuitive.

The SDR20’s product brochure lists some of its features:

  • 2-channel transceiver operation
  • Two methodologies for implementation: IQ Mod / Demod and Direct Down and Direct Up (DDC, DUC) conversion
  • Up to 200MHz bandwidth per channel
  • 100mW transmit power. Higly efficient 1kW exciter available separately.
  • Frequency range covers DC to 2.5 GHz
  • State of the art Altera Cyclone SOC-FPGA (Including dual-ARM9 Cortex)
  • Graphics Prosessor accelerated Multi-Touch screen with a slick user interface
  • GNURadio, C++ API/Python, VHDL/Verilog/High Level Synthesis sandbox
  • High-speed ethernet interface for computer connection
  • Internal clock 20 PPS
  • Coherent operation with external clock source (GPS, Rubidium etc.)
  • Rugged and stylish enclosure / Rack mount

Of course, the SDR20 is truly designed for industrial and government/military applications, thus it carries a price tag reflective of those markets: €3,395.00 (about $3,800 USD).

Still, seeing the SDR20 gives me hope that multi-touch, portable SDRs will become more commonplace as capacitive screens, processors, DSP chips and solid state storage continue to decline in price.  Indeed, I wouldn’t be surprised if Siru is able to lower the price on future iterations of their portable SDR line.

If you would like to take a look at some of the SDR20’s specifications, check out this PDF product sheet and the video embedded below.  Of course, you’ll find even more information and updates on Siru’s website. The SDR20 has shipped to Beta testers and should begin full production in the fall.

Upcoming Summer QRP Field Events

With the arrival of summer weather, the outdoor ham radio season is upon us! Outdoor operating is an important part of my ham radio hobby and I plan to participate in the following field events in a big way.

Saturday-Sunday, June 27-28, 2015: ARRL Field Day

Field Day is the ARRL’s biggest operating event and, with a history going back to 1933, is one of the ARRL’s oldest operating events. Field Day is the “big daddy” of portable operating events and more than 40,000 hams are expected to participate this year. Operate QRP or QRO. Operate CW, SSB, or digital; operate with a local club, a group of friends, with a single friend, or alone. The important thing is to set up a station and operate!

Full rules and other materials can be found here:
http://www.arrl.org/field-day.

I will be participating with the Athens County Amateur Radio Association’s Class 1A, solar-powered operation at the Athens County (Ohio) Fairgrounds.

Sunday, July 26, 2015: The Adventure Radio Society’s Flight of the Bumblebees

The Adventure Radio Society’s Flight of the Bumblebees hasn’t been around since 1933 but it has been an annual event since 1997, which is a long time these days. Flight of the Bumblees is a four-hour event held annually on the last Sunday of July. Both home-based and portable operations are allowed but those who operate from the field are the Bumblebees and are worth a 3x multiplier. Bumblebees are encouraged to reach their operating locations principally under their own power by walking, bicycling, kayaking, etc.; the distance traveled using human-power is up to the individual operator’s discretion.

Full rules and instructions for receiving a Bumblebee Number can be found here: http://www.arsqrp.blogspot.com/.

I have participated in Flight of the Bumblebees most years since 1997 and look forward to participating again in 2015. I plan to bicycle with my KX3 Travel Kit (info) from my home to my operating location somewhere in Athens County, Ohio.

Sunday, August 9, 2015: New Jersey QRP Club’s Skeeter Hunt

This year marks the 4th annual running of the Skeeter Hunt, a four-hour sprint-type event whose objective is to get QRPers out of their shacks for the day and into fresh air and sunshine. Those who operate outdoors qualify as “Skeeters”.

Full rules and instructions on receiving a Skeeter Number can be found here: http://w2lj.blogspot.com/p/njqrp-skeeter-hunt.html.

WD8RIF has participated in every Skeeter Hunt since the first one in 2012 and has enjoyed the event every year.

RKR Designs have acquired Alpha Amplifier and TEN-TEC brands

Ten-Tec-Alpha(Source: TEN-TEC Press Release)

(April 2, 2015) RKR Designs, LLC of Longmont Colorado has announced that they have acquired the assets of Alpha Amplifier and TEN-TEC brands from RF Concepts. RKR plans to expand the product line, while continuing to service their customers that have enjoyed their products over the years.

The principals of RKR Designs are Richard Gall, Ken Long and Rich Danielson (Gall and Danielson of QSC Systems, Longmont, Colorado have been a successful contract manufacturer, for over 20 years). Ken Long, N0QO has over 20 years in the electronics and amateur radio industry. Long will be President and CEO of the new company. QSC has been building Alpha amplifiers for over 5 years. They have also been building boards for TEN-TEC since their purchase by RF Concepts last year. Mr. Long said “QSC has always been a fantastic contract manufacturer, and has the expertise and knowledge that will allow us to bring down costs, while increasing quality and reducing manufacturing times.”

When asked for comment, Michael Seedman, AA6DY said “I can’t think of a more capable group of people to take over the 45 year Alpha Amplifier/TEN-TEC legacy. Ken Long has been involved with the industry for years, and has a great feeling for products and operations. He has the manufacturing and engineering resources available to deliver quality products that our customers demand”. Mr. Seedman went on to say “Alpha and TEN-TEC have always had a warm spot in my heart, and I am thrilled that RKR Designs will be able to continue the operations of the business. I wish them the best”.

Ken, Richard and Rich have been working very close over the past several years and feel that this new relationship will benefit the company and customers moving forward. This closer relationship to the contract manufacturer will allow a more consistent process and delivery of quality products along with significant cost benefits.

RKR Designs LLC is privately held, and terms of the acquisition were not disclosed.

Many thanks to my buddy Ulis (K3LU) for sharing this brilliant commercial:

RadioShack liquidation sales

[Note: This post was originally published on my shortwave radio blog, the SWLing Post.]

RadioShack-StoreClosing-2

One of my local RadioShack stores is closing and liquidating all of the merchandise and store fixtures. I’ve visited the store twice and found that the best bargains come from the components cases where everything was marked at least 70% off.

RadioShack-Components

I purchased about $60 worth of components like those above: test leads, connectors, plugs, adapters, RG-58 cables, fuses, breadboards, etc. Two packs of PL-259 crimp on connectors, for example, were about 70 cents each. Those prices are much better than you would find at a good hamfest; so I stocked up!

Several of you have commented about your local RS deals as well–SWLing Post reader, Troy, writes:

The Radio Shack® Digital Recorder you blogged about a few months back is marked down to $2.98 at Radio Shack stores – if it can be found. I drove 43-miles one way to buy one today. Despite gas and a $3 highway toll, I’m happy.

Radio Shack online inventory has historically been abysmal and given that stores are closing I’d encourage your readers to call stores – even if stock is listed as unavailable.

I haven’t tested it yet but from a previous post it appears software can convert the audio from mono to stereo. I’m sure I can figure it out with my MacBook Pro, but if not – given the modest expenditure – I’m satisfied nonetheless.

RadioShack-StoreClosing Many thanks, Troy!

If you are interested in snagging deals, you should act now. There is very little left in my local store and, according to a district manager I spoke with, items are moving as quickly in other regional stores. From reader reports, this is the case across the country.

Keep in mind: not all RadioShack stores are closing. Many franchise and corporate stores will remain open, at least for the time being.

Working K1N: The Navassa Island DXpedition

Lighthouse OP at night LED lighting (Photo: k1N DXpedition)

While I love QRP and ham radio in general, I must admit that I’m not much of a DXer. I love the idea of DX, but at this point in my life, it’s hard to make time for it and, frankly, my CW skills are somewhat lacking.

I owe many thanks, though, to my good friend, Vlado (N3CZ), who sat with me yesterday at his QTH and coached me through working K1N on 15 meters CW. It was a bit like learning from a Jedi Master…er, Jedi Elmer. At any rate, it felt good to see my call in the K1N log and to know that I worked a station that may not reappear for another 25 years.

If you have the time and patience, you might try working K1N soon.  I understand the K1N team announced earlier today that they intend to tear down their stations starting this Saturday.  They will go QRT Sunday morning.
