That font of all knowledge Steve G1KQH reports:

“Hendricks QRP Kits http://www.qrpkits.com has re-opened for business under its new proprietors, James Bennett and Kathy Long of Pacific Antenna.  James writes:

“We are excited to resume operations as of May 1 providing Hendricks QRP Kits and in the very near future, we will be bringing back the entire Pacific Antenna line of antenna kits and parts.  We very much appreciate the patience that has been shown as we worked through this transition and we look forward to serving the QRP community.  73 James and Kathy”

Some of you might remember me talking about the return of Heathkit.

There has been a lot of mystery surrounding the status of Heathkit, as they popped up a couple of years ago and announced that they were returning.  There was a survey posted online for a long time asking people what they wanted to see from a new Heathkit.  The new Heathkit management hosted a Q and A session on Reddit speaking more about their plans to return.  Then, nothing.  No announcements, no news.  There was brief mention in December when the folks at Adafruit (a company that supports the MAKER community) were briefly in touch with the new Heathkit, and were told that things are still progressing, and there will be no information on what the products will be until they are ready.  All through this, I have been skeptical, as many people would be, since we have heard this story before.

Now, there are changes over at Heathkit.com.  They are clearly gearing up for products, and support.  They have even started an eBay store where they are selling parts, and some classic equipment.

Cross your fingers.

Sixbox 6m AM rig – a simple design

Several years ago I designed and built a derivative of my 2m Fredbox but for 6m AM. The same basic design would easily translate to a 10m version.  Both bands could be useful for cross-town natters, especially when both 10m and 6m behave like VHF bands, which is in the quieter sun years and at night on 10m. The Sixbox is simple and certainly capable of further development.

Treat the design as a starting point. A 10m version of the RX has copied transatlantic USA AM stations well, but this is NOT a rig for DX use. It is better suited to cross-town/inter-village natters.

See https://sites.google.com/site/g3xbmqrp3/vuhf/sixbox .

Depending on the solar cycle, and how good it is, both 10m and 6m can behave quite differently. Sometimes 10m is a true HF band with good worldwide DX possibilities. In better years, even 6m can support F2 worldwide propagation. However, for a lot of the solar cycle both 10m and 6m behave like VHF bands.  This means Es can be an effective mode on both bands especially in the spring and summer months. Other modes like tropo can also be used on 10m and 6m. Both bands can be used for local natters on any mode.

At the moment we are in a transition period. On better days 10m is still good for worldwide DX but as time progresses, it will behave more and more like a VHF band with long periods of quiet. Especially as we move to more VHF conditions modes like WSPR become even more useful: short DX openings can be detected with WSPR.   Leaving a simple WSPR rig running can be so useful and take very little power.

As I have mentioned before, I have worked real 10m N-S DX (11000+ km) on QRP SSB even in the quietest of sunspot years. WSPR is considerably better than SSB, requiring far less power and can be used unattended running in the background. I tend to run 10m and 6m WSPR most days and monitor WSPRnet on a different PC in the lounge.  It takes just seconds to go into the shack and make any adjustments needed.  It means, whilst running WSPR, you can do other things.

See http://www.kanga-products.co.uk/.  Although I have to admit that I have not used this supplier or its sister site in the USA, they seem to have a useful range of kits and products in stock.  If you are after QRP or QRSS frequency crystals, then these are at a decent price.  I have no idea how well priced their other items like solder are compared with other suppliers.

As I have said before, these suppliers could soon disappear if they do not get enough trade. The competition from China is fierce indeed and many very good bargains may be had on eBay.  I wish Kanga well.

DIY: The Home-Brewer’s Primer
By Richard Fisher KI6SN
Building transmitters, shortwave receivers, antennas and station accessories is an art dating to the late 19th Century—the earliest days of radio. Almost every radio operator of the era was a builder, because commercially made radio gear was either nonexistent or, at the least, quite expensive. The term “home-brewer,” those who toiled at the workbench in order to tune in shortwave or get on the ham bands, would become a badge of honor and part of the lexicon of amateur radio. Home-brewing radio equipment is as vital to today’s radio amateurs as ever!

The Newcomers Net: Bringing together Newbies and Old-Timers
By Robert Gulley AK3Q
Like so many things in life, amateur radio is caught just as much as it is taught. Elmers (amateur radio mentors) and Newcomers really do feed off of each other, and excitement tends to generate more excitement. Whether it is trying new things or rediscovering long-lost passions, both newbies and old-timers alike grow from their shared experiences. Robert writes about the second anniversary of The Newcomers and Elmers Net, a weekly, on-air meeting of the OH-KY-IN Amateur Radio Society, geared toward pairing newcomers to the hobby with Elmers willing to offer them advice and the benefit of their experience. What they’ve done can be applied nationwide.

Digitally Speaking: Digital Voice on 220 MHz?
By Cory GB Sickles WA3UVV
Our amateur radio allocation at 222-225 MHz is among those that have been left out of the “Digital Voice Club.” As this is a band exclusive to the Americas, manufacturers are less inclined to invest in producing gear than for UHF. Currency fluctuations and lowered levels of interest limit the potential payoff for commercially produced gear. Cory ponders the question, “What will it take to get digital voice on 220 MHz?”

Southern Amateur Radio Hospitality: N4H and WA4USN Special Event Station
By Ron Walsh VE3GO
Canadian TSM Maritime Monitoring columnist, Ron Walsh, encounters “southern hospitality amateur radio” when he signs up to help man WA4USN aboard the US Navy battleship, the USS North Carolina, based in Wilmington, North Carolina and N4H near the site in South Carolina where the Civil War-era submarine, H. L. Hunley, sank after having been the first such vessel to sink another ship, the USS Housatonic, in battle. Ron had the opportunity to study US Naval history and operate two special event stations during his annual southern winter holiday.

TSM Reviews: TitanSDR
By Thomas Witherspoon K4SWL

After discovering the power of software-defined radios (SDRs) a few years ago, Thomas has been hooked, and now does 95 percent of his home listening and monitoring via various SDRs in his collection. In this issue he turns his attention to a newly released military-grade SDR called the TitanSDR. He’s impressed with its performance, but will this super-sophisticated SDR live up to its military budget price tag?
