KJJR DX Test on Saturday (May 2, 2002)

Many thanks to SWLing Post contributor, Paul Walker, who shares the following announcement:

KJJR 880 Whitefish, MT(Kalispell) will test for 1 hour at 10kw non directional Saturday May 2nd 12:01am to 1am mountain time. It will consist of morse code, sweep tones, along with various telephone sound effects

There will be no paper QSL’s issued for this test. Only emailed confirmation. Send an email to [email protected] with “KJJR 880 DX Test” in the email (You MUST put that in that subject line so I don’t accidentally delete it thinking it’s spam!). The reply will likely be a simple email reply with details of the station and confirming the details of what/when you heard it. You WILL get a reply from me in due course, please give me some time!

This is done on short notice and being kept simple as to not burden anyone involved. Thanks to Les Rayburn for creating the test material and Todd Clark for generously offering up the station. I’ve already seen communication between him and the station, asking them to block out an hour from the logs, so he can tinker around with things at the tower site.

Thanks for the heads-up, Paul! Here’s hoping a few MW DXers can log this test.

When Dagwood decided to become a radio repair technician

Many thanks to SWLing Post contributor, Dave Zantow, who shares a link to this 1947 “Blondie & Dagwood” episode #21. Dave notes that the part of the episode with a radio slant starts at approx. 24:22:

Thanks, Dave! I’m not sure I’ve ever watched an episode of Blondie and Dagwood, although I’ve certainly read hundreds of the comic strips and listened to many episodes of the OTR shows.

In fact, if you’d like to listen to some of the Blondie and Dagwood radio shows, the Internet Archive has a collection of 42 episodes that you can stream or download.

The story of a 1970s CB Radio QSL card print house

Many thanks to SWLing Post contributor, Ulis (K3LU), who shares the following story of a popular CB Radio QSL Card design and print house:

73s and 88s :: The Ballad of Runnin Bare and Lil White Dove

We set a custom screensaver on Our AppleTV. Told it to pull images from Flickr tagged with “British Columbia.” After my wife and kids and I spent a few weeks in Vancouver and in various places on Vancouver Island, it had become one of our favorite places. We missed it.

And so, at night, after a show or movie ended and the AppleTV sat idle for a few minutes, a slideshow would automatically begin. The Parliamentary Buildings in Victoria, the Inner Harbor, the wild, rocky, tidepool-rich shores of Tofino, the murals of Chemainus.

Then, every once in a while, an illustration of some sort. I couldn’t tell what. A one-panel comic? Some kind of advertisement or flyer? It would be gone from the screen before I could really get a good look. Weeks would go by and I wouldn’t see it until, once again, there it was. It looked old, like something from the 60s or 70s. And it had numbers on it, like a code or a message: 73s and 88s.

It was the numbers that got me. Like the park rangers in The Shining calling for Wendy Torrance on the radio: “This is KDK-1 calling KDK-12. KDK-1 calling KDK-12. Are you receiving me?” They seemed to be saying something. But what? I had to find out. So, I took to Google, and began my search.[…]

FYI: Although the CB Radio landscape is quite different than it was in the 70s, most modern shortwave radio receivers can tune to CB channels. Here’s a quick tutorial from our archives.

The Tecsun PL-330: Some details about this compact shortwave portable in development

Source: tecsun.com.cn

Many thanks to a number of SWLing Post readers who shared a link to this website (in Chinese) with photos and details of the new Tecsun PL-330. Note: The server hosting the PL-330 page has been unreliable the past few days.

Some of you might recall the PL-330 in photos of the new Tecsun product line we posted last year. Recently, a handful of preliminary working prototypes have been produced,  so I reached out to my trusted Tecsun contact for more information. Here’s what I’ve learned:

Position in Tecsun product line

In terms of the Tecsun product line, the PL-330 appears to be the successor to the venerable Tecsun PL-310ET and/or PL-380.

The PL-330 will have features these legacy Tecsun models do not have, namely:

  • synchronous detection,
  • single-sideband reception,
  • and an upgraded ETM (auto tune and store) feature.

It also appears the SSB tuning steps could be as fine as 10 Hz. Most impressive, if true.

Size

Size comparison: PL-330 (left), PL-990 (middle), H-501 (right)

I refer to radios in this size class as “ultra-compact.”

The PL-330 measures 139 × 85 × 26 millimeters (5.5 x 3.3 x 1 inches). Its form factor is very similar to the PL-310ET, but much thinner in profile. The total depth of the radio is only 26 mm.

I love the idea of an even thinner profile, although this certainly limits the type of internal battery that can be used.

Battery

The PL-330 is powered by a single BL-5C lithium battery.

In my world, this is a bit of a negative, but I’m sure the BL-5C was one of the only viable battery options for a radio that’s only 26mm thick.

On the plus side, the BL-5C is widely available, affordable, and can be charged internally.

On the negative side?

Well, I find that the overall capacity doesn’t match that of, say, three AA batteries. Also, I find that the battery’s longevity (meaning, how many charge cycles it can handle) is not that impressive–arguably worse than any other rechargeable battery system I’ve used.

Another reason I prefer AA batteries in compact portables is I know no matter where I travel, I can easily purchase them at almost any retailer, airport, or even hotel, in a pinch. In the past, when I’ve traveled with radios that use the BL-5C, I simply carried a fully-charged spare in a poly zip-lock bag (to protect the battery contacts from inadvertently shorting.

In addition, when I fly, I like to carry as few Lithium batteries as possible.

Perhaps, however, I can find a very high quality BL-5C to use in the PL-330? I would appreciate any leads from readers.

Performance

Since the preliminary prototypes were more or less mechanical prototypes and lacked most of the features planned for this model, there are no performance reports as of yet. In fact, I would be skeptical of any reports you might read in advance of the final production model.

Availability

Like the PL-990 and H-501, there are no reliable estimates for availability or shipping yet. The Covid-19 pandemic has slowed down this process. Most likely, the PL-330 will be released after the PL-990 and H-501, but that isn’t even certain.

Stay tuned!

The PL-330 will have a number of other features and specs, but these are early days and I prefer sticking with what we do know now. As soon as I learn more, I’ll post updates–bookmark the tag PL-330.

Note this reddit thread with an English translation of the Chinese page I mentioned at the beginning of this article (thanks, Tom Daly). It mentions more details, but again, it’s such early days I prefer to stick with what has been confirmed. As with any product in development, a number of changes could occur before the first production run.

Of course, I will review and evaluate the export version of the PL-330 when as soon as it’s available. Stay tuned!

John adds a pre-amp and rotatable stand to his homebrew NCPL antenna

A couple weeks ago, we featured John Mills’ homebrew Noise-Cancelling Passive Loop (NCPL) antenna (see photo above) in a post with two other Post community designs.

John recently shared an update to his project:

As promised, some more pictures of my antenna mounted on a rotatable stand. I have used standard (in the UK) 20mm electrical plastic conduit and fittings to make the frame.

Fitted a small plastic box to house the balun and have put a BNC socket on the underside of it for connection the coax cable to my Rx.

I have also been experimenting with cheap low cost amplifiers (LNA) found on eBay (see picture) which do seem to improve the general strength of signals by 10-15db, but the baseline noise also rises.

I did manage to hear a QSO on 160M using one of these which was inaudible without the LNA but I cannot say for sure yet if they are worth the extra noise introduced.

Thank you for sharing your update, John! The plastic conduit support is simple and effective! Indeed, it looks very professional. What I love about your NCPL build (loop, stand, and LNA) is it that it’s all incredibly affordable as well.

Read more about John’s NCPL build in this post.

Post Readers: Has anyone else experimented with implementing a pre-amp in their NCPL antenna design? Please comment!
