Say “Hi” to Juno as it passes by Earth today
Many thanks to SWLing Post reader, Troy, who emailed me about a really fun and unique opportunity for amateur radio operators: to send the NASA spacecraft Juno a Morse Code greeting [specifically, “HI”] when it passes over Earth tomorrow, starting around 18:00 UTC.
The NASA Jet Propulsion Laboratory explains:
“NASA’s Juno spacecraft will fly past Earth on October 9, 2013, to receive a gravity assist from our planet, putting it on course for Jupiter. To celebrate this event, the Juno mission is inviting amateur radio operators around the world to say “HI” to Juno in a coordinated Morse Code message. Juno’s radio & plasma wave experiment, called Waves, should be able to detect the message if enough people participate. So please join in, and help spread the word to fellow amateur radio enthusiasts!
This page will be updated with additional information as the event approaches. In addition, we have created a Facebook event page where you are welcome to a discuss[ion of] this activity.”
To be clear, this is a coordinated and unified message to the Juno craft; there will be no opportunity to hear a response from it. Rather, the Waves instrument data containing the message will be shared by the Juno team after the flyby. But still, what fun!
If you’re a licensed ham, and this sounds like something that you’d like to be part of, please check out the the NASA JPL page dedicated to this event. It has all of the information you’ll need to transmit to Juno, including a countdown clock–or to simply listen to everyone who does. Be sure to check out Juno’s Technical FAQ (click on the FAQ link) which answers a lot of the questions participants have already asked.
I’ll certainly do my best to be a part of the unified greeting to Juno.
I should note that I’m pleased to see the JPL page is running despite the US government shutdown. Many other NASA web pages have been affected.
Hi, Juno; we send our greetings!

A New Field Event — “Peanut Power Sprint”
The North GA QRP Club gang have added a new annual field event to the amateur radio contest calendar–a field event with an unusual twist. The Peanut Power Sprint is this Sunday, September 29, 2013, from 2000Z to 2200Z.
What’s unusual about this event is that it is open to those operators running QRP, those running more than QRP power, those operating at home, and those operating in the field. Participants will be competing against only those who are in the same class. In addition, both CW and SSB operation are allowed and encouraged.
Here are the full rules, in PDF format: http://www.nogaqrp.org/Peanut%20Power%20QRP%20Sprint.pdf
A couple of items to note in the rules:
- Operations are allowed only on 15, 20, and 40m. The recommended 40m CW frequency is 7.060MHz, not the usual QRP calling frequency.
- Those operators with a “Peanut Power Number” can work anyone; those without a number may work only those with numbers. It’s not too late to request a “Peanut Power Number”.
Personally, I’m looking forward to be operating as Peanut Power #105, “Salted” (5w, portable).

HackRF: an open source SDR transceiver
[From my shortwave radio blog…]
Michael Ossmann is making a business out of developing and producing open-source hardware.
His latest creation is called HackRF, and in less than a day, it has been fully backed on Kickstarter raising over $290,000 US with 25 days left to go in the campaign (at time of posting). Backers can contribute to this campaign with some confidence as Ossmann has successfully delivered products from Kickstarter in the past.
What makes HackRF unique is the fact that the stand alone unit can operate between 30 MHz and 6 GHz; a frequency range substantially wider than any SDR currently on the market. Indeed, when combined with the Ham It Up converter, the HackRF will also cover HF bands and lower.
Additionally, HackRF is a fully open-source transceiver; applications are limited only to a developer’s imagination. You could potentially use HackRF for ham radio, radio astronomy, scanning, shortwave radio listening, remote control applications, wide band monitoring, and commercial/industrial applications. If you use two HackRFs in tandem, they’ll even work in full-duplex applications.
Though the project is fully-backed, you can still support HackRF in the Kickstarter phase and save a bit on the eventual retail cost of the unit. Production units are expected to ship early 2014. Check out the HackRF Kickstarter video below:
Additional information:
- Check out HackRF technical details and development notes at the HackRF wiki.
- Source code and hardware design files are available in the latest release packages or in the git repository.

BBC World Service interviews Paul (N6PSE)who is attempting to organize a DXpedition to North Korea
(Source: BBC World Service)
A small group of US ham radio enthusiasts have been in North Korea recently to ask for permission to set up a ‘pop up’ ham radio station there. Paul Ewing is one of them; he wants to lead a group to set up a call sign for two weeks, to make contacts around the world from perhaps the most isolated society in the world. The BBC’s Dan Damon asked Paul to explain.

Hamvention: Tokyo Hy-Power’s XT-751 5W HF HT
I was very surprised to find this handy talkie, the Tokyo Hy-Power XT-751 HF handheld transceiver, at the Dayton Hamvention. This radio will cover from 40 meters to 6 meters in both SSB and CW. It will also have an internal ATU. It is only a concept radio at this point.
Tokyo Hy-Power hopes to have this radio in production mid 2014.
Hamvention: Palstar announces the TR-30
I was more than surprised to find Palstar showcasing a transceiver at the 2013 Hamvention. Palstar is well-known for their tuners and their receiver, the R30A, but they have never sold a transceiver to my knowledge.
As you can see from the photos, the Palstar TR-30 has a simple faceplate with a touch screen display. It is all aluminum, thus is very light. TR-30 is rated for 20 watts PEP and has an 11 pole filter on board.
I hope to review one once it is in production. Palstar expects the TR-30 to be available August 2013.
When I asked about the price, the told me a range of $1,500-2,000 US. (Gulp!)
TEN-TEC Introduces the Model 506 Rebel: an open-source QRP transceiver
Today, at the QRP ARCI convention–Four Days In May–TEN-TEC will announce a new QRP transceiver based upon a completely different platform than any others rigs they have in production: a QRP radio, built on the chipKIT™ Uno32™ (Arduino-based software) to be known as the Model 506 Rebel.
And, folks, I’ve been lucky enough to get my mitts on a prototype…!
The Model 506 Rebel
The TEN-TEC Model 506 Rebel is an open-source (meaning, anybody can program it), factory-built QRP transceiver based on a Chip Kit Uno 32 Arduino-compatible prototyping platform, which serves as the main processing unit that holds the Rebel’s program. (For those of you not familiar with the Arduino series, check out this article.)
And I have to admit, I love the concept: TEN-TEC delivers a factory-built, uber-simple transceiver, with just enough programming to reliably get you on the air with a basic radio (see details below). Users then have full access to develop and program the Rebel via an open-source platform, themselves. No need to wait on firmware revisions; firmware, in a sense, will be crowd-sourced! That’s to say, it uses online collaboration–a great idea.
According to TEN-TEC, the programming environment is very safe. Users can tinker with code without fear that they might harm their Rebel 506. The original base program can be re-flashed to the radio at any time. So if you can’t get past an error, you can always revert to a safe default copy.
In addition, even if you don’t have any idea how to program, someone has already created a web-based email group where users can upload and share code packages, and you can select someone else’s programming to test drive. Click here to join the group.
The Rebel is a CW-only transceiver that operates on 40 or 20 meters. The user changes bands by moving jumpers inside the chassis, mounted on the PC board.
The basic Rebel comes with no frequency display. When you turn on the radio, it comes up on the QRP calling frequency of 7.030 MHz or 14.060 MHz, depending on which band is selected. There is no VFO, but a DDS chip that is highly stable and that allows the Chip Kit Uno 32 to select a frequency upon which to operate. Of course, since the Chip Kit controls the DDS chip, you can re-program how the Rebel manages frequencies.
Initial impressions
Last week, TEN-TEC sent me a prototype of the Rebel to Beta test. I’ve had it on the air several times–I’ve also popped the cover and given it a thorough inspection and workout. I’ll share my initial impressions below. I’m not commenting, however, on some specs like filtering, as they have not been finalized for production and are still subject to change. The unit I tested, keep in mind, was a prototype; production units will be still more polished and incorporate changes Beta testers have provided.
Front Panel Layout
The front faceplate of the Rebel 506 is reminiscent of TEN-TEC QRP Kits, gloriously clean and simple. There is a large tuning knob in the middle with a SELECT button on the left and FUNCTION button on the right. Both buttons are large enough that you could comfortably use them even if wearing winter gloves. Above each button is a vertical row of just three LEDs: green, yellow and red. These colored LEDs simply indicate the position of the function/selection buttons.
Function button controls
- Band Width
- Step Size
- User-programmed functions
Select button selects
- Bandwidth: Wide, Medium and Narrow
- Tuning steps: 100 hz, 1 kHz or 10kHz
- User, U1, U2 or U3
There are only two knobs: one for volume (AF gain) and one for RIT (+/- 500 Hz). There is also an ON/OFF simple toggle switch, and a rather classy touch from TEN-TEC–namely, a small LED light in the TEN-TEC logo itself. And that’s all, folks–bare-bones design.
No frequency display
The Rebel 506 does not come with a frequency display. However, there are features to help you understand where you are on the band as you turn the encoder:
- As you tune within the selected tuning steps, the LED in the TEN-TEC logo flashes as you pass each step; for example, if you’ve selected 100 Hz steps, then when you pass each 100 Hz step, the LED in the logo will flash once. When you reach either band edge, the LED stays lit. Again, a nice touch.
- When you turn on the (factory default) Rebel, the frequency starts on QRP calling frequencies 7.030 MHz (40M) or 14.060 MHz (20M)–of course, you could change these with programming.
- There are (already) third-party frequency displays that plug into the Rebel’s board, an easy addition.
Since I had neither frequency display nor frequency counter, I simply used my SDR’s waterfall display to locate where I was on the band. It’s also fairly easy to count the steps with the logo’s red LED.
Connections
On the rear panel, you’ll find a standard BNC antenna connection, a key/paddle port (1/8″), a speaker/headphone port (1/8″) and a standard DC port (10-15V reverse polarity protected) that equates to 4-5 watts output depending on supply voltage.
Key/Paddle input from the factory is only for straight key, but you can modify the code to make it a paddle input. Also, the headphone/speaker port defaults to headphone use from the factory, but there is a small jumper on the PCB that can me moved to drive a non-amplified speaker.
On production units (not on my prototype, however, nor on those at FDIM) there will be a CW side tone volume control pot via a small hole in the side of the Rebel’s enclosure. Also, production units will have a hole on the rear panel to allow for access to the ChipKit’s USB port.
The PCB has hooks, test pins, and inputs for the following:
- Battery read pin: reads 0.20 of the supply voltage.
- Power-out read pin: reads 0.50 of the RF pickup
- Code read pin: ties to low level audio line, can be used to build a CW code reader
- CW-speed read pin: DC voltage used to determine approximate speed of CW routine
All connections of the Chip Kit Uno32 are available on the top of the PCB.
The unit accepts Arduino-compatible Shields for such things as:
- Prototyping
- Displays
- Audio DSP
Evidently, the Rebel has a lot of memory space for writing CW memory-keyer functions or whatever the user desires/dreams up. Even a voice synthesizer could be installed in the Rebel; indeed, I believe there are many mods and possibilities for the Rebel. The greatest limitation might simply be…the imagination of the user.
TEN-TEC was clear with me about the goal of the Rebel 506: “To provide a platform for users to experiment and to learn to program using Arduino-Compatible Code.”
I like it!
I have thoroughly enjoyed putting this little radio on the air. Let’s be clear, though: this is no Argonaut VI or Eagle, nor should it be expected to be. Receiver performance is on par with other QRP kits and rigs of its class. The Rebel is fairly sensitive and the noise floor is fairly low. Selectivity is adequate for most conditions, although I imagine crowded conditions could overwhelm this modest receiver.
When I had the Rebel on the air, I engaged in a bit of a rag-chew and found the audio quite pleasant from my GoalZero portable amplified speaker. And other than needing to adjust the side tone volume, the Rebel was ready to go, straight out of the box.
Criticisms? Well, it’s just too early to have many. I’ve passed along all my frank observations to TEN-TEC and they’re actually addressing them now (yet again, one of the many benefits of an American-based radio producer). If this were a $900 rig, performance-wise, I would complain about selectivity. But I’m willing to bet it’s at least as good as the Index Labs QRP ++ I once owned. In fact, though it’s not a full-featured general-coverage rig, it has that same sort of bare-boned fun factor the Index Labs radio provided me, along with many other QRP kits.
Field? I would totally take the Rebel into the field or backpacking. I have a hunch it uses less than 200 milliamps on receive. It’s modestly-sized and built like a little tank.
The Rebel lives up to open-source philosophy
Here is the amazing part about the Rebel: TEN-TEC only shipped me the radio–no connectors, no adapters, no power cord. At first, I thought I’d have to find an appropriate plug and solder my own power cord, not to mention figure out what other adapters I would need for my key/speaker…but I didn’t. The power port is very standard; the same one my LDG ATU, Elecraft K2 and KX1 use, with standard positive tip polarity. The Rebel’s antenna connector is a BNC, speaker and key ports are standard 1/8″ and the ChipKit board has a mini USB connection. The top cover is easy to remove–even the toggle switch, LEDs and selection buttons are all standard and easy to access for servicing. Everything is standard!
But it doesn’t stop there. The Rebel is truly an experimenter’s radio, and is meant to be. The programming is completely open-source and TEN-TEC is encouraging and facilitating users to tinker with the code and make hardware modifications at will.
Open-source technology is all about alteration and collaboration, the kind of environment we hams have always embraced. In the open-source world, nothing is proprietary; rather, everything is transparent, standard, accessible; supporting changes and modifications of every stripe. And in my humble opinion, it’s about fun. On these points, the Rebel delivers.
I have done some scripting in my past, but I am no professional programmer. Though many of my Maker friends had been urging me to give it a go, I hadn’t jumped on the Arduino band wagon until, well, now. The Rebel will serve both as a great intro to Arduino Compatible Code and a truly fun QRP rig. If TEN-TEC is lucky, this little rig may actually nudge some of my Maker friends to get their ham radio tickets.
Price
TEN-TEC will be announcing the price of the Rebel 506 in Dayton, literally in just a few hours. I have no idea what it will be, but I’m fairly sure it’ll be competitive with other dual band QRP transceivers and kits on the market. I’ll post an update here when the price has been published. Stay tuned…
UPDATE: Pricing for the Rebel is $199 US.
By the way, if you’re at FDIM or the Hamvention this year, drop by booth 411 in the Ball Arena: I’d be happy to talk with you about the Rebel further (and my radio-based non-profit, Ears To Our World).
Disclaimer: Just to be clear, although I own TEN-TEC (also Elecraft and Yaesu) products, and although I Beta test for TEN-TEC on occasion, I have no formal relationship with TEN-TEC. Nor am I compensated by the company in any way. The opinions in this article and others on this site are frank and my own; they are not those of TEN-TEC.
