How Far We’ve Come: Looking Back at Radiotelegraphy, 1939 Style

It’s often insightful to look to the past to fully appreciate the current technology we take for granted.

When we tap a favorite contact’s name in our mobile phone–even for someone on the other side of the world–we can be talking to them within seconds, with clarity that’s often the equal of visiting face-to-face. Perhaps Skype or FaceTime is more your style? Yawn… just another two-way, real-time video session. The fact that the other person is thousands of miles away no longer makes you pause at the wonder of it all. Continue reading →

Can you help Joel ID this Vietnamese station?

“Is there a section of SWLing Post for SWL’s who manage to catch a highly unusual broadcast about which some of your members may have information? I refer to catching an S4+ transmission in northern Vietnamese from 1600-1630 GMT on 11,840 kHz last November? As linguist, SWL, ham and retired foreign service officer, this one has me totally stumped.”

Joel, I’m hoping a reader can assist you with your question. My only guess would be that this was a Vietnamese broadcast from KTWR Guam.

Please comment if you can help Joel identify this station!

I think you and your readers might enjoy these videos.

I’ve upgraded from a Tecsun PL880 and Sangean ATS909X to a JRC NRD535D. I live in Camden, Arkansas which is in southern Arkansas, 75 minutes east of Texas and 75 minutes north of Shreveport, Louisiana

When DX’ing on shortwave, I often record a short video with my iPhone 6plus held up close to the radio so you can see the frequency and signal level meter.

I record videos anywhere between 20 seconds and 5 minutes depending on what I feel like at he moment and what I will be using the video for. Sometimes I record a shorter video to post on Facebook then record longer audio via an MP3 recorder in my phone to use in a reception report.

Sometimes I record long 3-5 minute videos and send those to the station instead.

I don’t record everything I hear but what I feel is a worthwhile catch or is interesting. My videos can be seen here:

Thanks for sharing a link to your videos, Paul! You’ve got some good catches in your library. That JRC NRD535D is a great receiver, too–noise floor seems quite low!

Video: Shortwave listening and radio astronomy

3 Replies

On Thursday I attended an event at the Pisgah Astronomical Research Institute (PARI)–location of the 2015 SWLing Post DXPedition.

During a break, I had a couple of free hours, so I reached in my messenger bag and pulled out the Sony ICF-SW100: a radio that has quickly surpassed all others as my favorite EDC (everyday carry) radio. It has so many useful features in such a small package!

Radio astronomy observatories are ideal locations for impromptu shortwave radio listening as there is little to no radio interference/noise present.

PARI’s “Building 1” and the 26 West (left) and 26 East (right) radio telescopes.

While the weather on Thursday was gorgeous, HF band conditions were…well…miserable. There was very little to hear other than China Radio International, Radio Havana Cuba and a few other blow torch broadcasters.

Still, time signal station WWV was on my mind since I had just purchased Myke’s new edition of At The Tone and have been reading your excellent comments with early memories of listening to WWV and WWVH.

I tuned to 15 MHz and, of course, there was reliable WWV in Fort Collins, Colorado on frequency. Though WWV’s signal was relatively strong (despite the conditions) I turned on the SW100’s sync detector because fading (QSB) was pronounced at times.

Here’s a short video of the ICF-SW100 on a picnic table in the middle of the PARI campus. That’s PARI’s 26 (meter) West telescope in the background:

SWLing Post DXpedition at PARI…this weekend!

If you’ve registered for, and plan to attend, the PARI DXPedition, please make sure you’ve joined our Yahoo Group. This is where we’re finalizing details and communicating about the DXpedition, noting any changes, updates, etc.

If you’ve tried to contact me recently and haven’t gotten a response yet (sorry about that!) it’s because I’ve been unusually busy: writing a shortwave radio buyer’s guide for The Spectrum Monitor, several reviews for WRTH 2016, plotting another reader challenge, and last but not least, putting together the final details of the SWLing Post DXpedition at PARI this weekend.

Soon I’ll be another kind of busy, at the DXpedition: exploring the bands, gazing at the stars, and hanging out with some of the SWLing Post community. Needless to say, it’s going to be fun, and I’m looking forward to it.

If we have Internet access at PARI, we hope to post a few loggings and photos from our Twitter account.

We have about a dozen registrants this year, a good start. If you can’t make it there, no worries; if all goes well, we may have another next year.

Alan logs shortwave stations while camping

I really appreciate your site. It has been my favorite since I got back into shortwave listening and DXing…great enough that I actually subscribe to posts via e-mail so I don’t miss anything.

In case you are interested, I did a post about what I was able to hear using my Kaito KA1103 and a Sangean antenna while camped in a tent in the back yard. Nothing amazing by many people’s standards…but I enjoyed it enough to stay up too late!

Either way, thanks again for SWLing.com.

Alan, there are few pleasures in life better than SWLing while camping–even if it’s in your own back yard! Thanks for sharing your experience and thanks for the kind comments. This weekend I hope to log a few stations from my tent at the SWLing Post DXpedition.
