Treetop Antennas: Featured with my friend Wlodek (US7IGN) on BBC Radio 4 Short Cuts

I’m very honored to be featured with my good friend Wlodek (US7IGN) in a short radio documentary on BBC Radio 4 today.

Wlodek is long-time reader and subscriber here on the SWLing Post and QRPer.com. Wlodek lives in Kiev, Ukraine and we keep in touch these days over email. Like me, he is passionate about field radio work and before the Russian invasion, you’d often find him in nearby forests experimenting with some pretty impressive field antennas.

Sadly, when Russia invaded Ukraine earlier this year, it very quickly brought an end to all of that for Wlod. Not only were amateur radio operators not allowed to transmit under the state of emergency, but it’s no longer safe to venture into nearby forests.

Radio producer, Cicely Fell, learned about our love of all things field radio and put together an audio piece that airs today on BBC Radio 4:

BBC Radio 4 Short Cuts

From the forests of North Carolina, USA to the city of Kyiv, Ukraine – two ham radio enthusiasts seek each other out and a voice from the past prompts a dialogue on listening between a rabbi and a radio producer.

Many thanks to Cicely and her talented team at Falling Tree Productions for spending a little time with us in the forest and on the air! Truly an honor.

Updates: Return of the lab599 Discovery TX-500, QRPer.com, and YouTube

Last year, I was lucky enough to obtain a lab599 Discovery TX-500 QRP transceiver to review for The Spectrum Monitor and the SWLing Post.

I could only keep the TX-500 for a one week evaluation period because it was one of only two or three pre-production units in the US–one was being evaluated for FCC approval.

Often, when a reviewer is sent a loaner unit, if we really like it we can purchase it from the manufacturer for roughly market price. The TX-500 was so rare, though, this simply wasn’t an option. Had it been, I would have purchased it. I liked the radio that much.

 

This week, I took delivery of a new TX-500 sent directly to me by the manufacturer in Russia. (You’d better believe I’m not sending this one back! I’ve already given it a name!)

If you’re interested in why I like the TX-500, check out my in-depth review here on the Post.

I will say this: if you’re a ham radio operator that likes SWLing, the TX-500 is a very capable broadcast receiver. Since I took delivery, I’ve had some pretty long listening sessions with the TX-500 on mediumwave and shortwave. The AM filter width is adjustable and can be quite wide if you want full fidelity. You must use an external speaker or headphones with the TX-500: this portable transceiver is sealed so that it’s weatherproof. The supplied speaker/mic works in a pinch, but I much prefer headphones or one of my amplified speakers.

QRPer.com: the other blog

I realize that many readers here on the SWLing Post aren’t aware that I actually have another blog dedicated to ham radio in the field: QRPer.com.

QRPer and the SWLing Post were actually born around the same time in 2008, but over the years I put much more effort and energy in the SWLing Post as I felt there needed to be better resources, articles, and information out there about radio listening. The SWLing Post has grown to a community of 8,000-9,000 daily readers and I couldn’t be more proud. There are days it really feels like a big, international family of kindred spirits. I’ve learned so much from this community.

QRPer is devoted to low-power amateur radio operation in the field. It has a completely different feel than the SWLing Post as most articles are field reports from my Summits On The Air (SOTA) and Parks On The Air (POTA) activations. I post at least one field report each week and typically test a different pairing of a transceiver and antenna. Many of my activations these days are using CW (Morse Code). After completing my first CW activation last year, I truly fell in love with this earliest of radio modes.

Click here to read my latest SOTA/POTA field report on QRPer.com.

I get that there are many here at the Post that don’t really care for ham radio or QRP operation and that’s perfectly fine. I mention QRPer because I’ve been getting notes from readers who are just realizing that there’s a common connection between the SWLing Post and QRPer: me!

I’m horrible at cross-promoting my work, so there you go.

Not a YouTuber, but I have a YouTube channel

While I’m at it: last year, I also started making real-time, real-life, unedited YouTube videos of many of my QRP field activations.  I made some of the first ones at the request of readers who wanted to know what it was like to actually perform field activations.

I’m a fellow who has very little free time and the thought of editing videos, frankly, makes me break out in a cold sweat. I simply don’t have the time. Plus, I don’t really have the personality of a successful YouTuber. I am what I am.

I posted my first unedited videos expecting negative comments. The total opposite happened.

While I never expect my YouTube channel to appeal to anyone beyond a very niche audience, I have gotten some very encouraging comments from subscribers who appreciate (virtually) sitting with me on the park bench or on a 3,000 meter summit and copying the CW and SSB contacts that roll in. I see these videos as supplements to my field reports on QRPer.com. In fact, if you want to see the Discovery TX-500 (mentioned above) in action, you’ll want to read my field reports on QRPer.com and watch the activation videos.

If you’re looking for a proper cure for insomnia, here’s a link to my YouTube channel. Consider subscribing if I haven’t scared you away already. 🙂 Indeed, as I publish this post, I see that I’m almost at the 3,000 subscriber mark. What?

Oh, speaking of YouTube and the TX-500, I made a video shortly after receiving it via DHL. I call it an “unboxing” video but really it’s an excuse to talk about why I’ve missed the TX-500.

By the way: I don’t monetize my YouTube channel, so there are a total of ZERO ads. I’m able to support my radio and blogging life via the backing of my amazing readers and sponsors. Thank you so very much!

QSO Today Podcast

I’m honored to have been interviewed by Eric (4Z1UG) for his QSO Today podcast. The interview was posted as a podcast this week.

We recorded it a couple weeks ago via Skype. My home Internet service was so terrible that day, I actually drove into town, parked in a parking lot, and used Skype via my mobile hotspot.  I was pretty distracted during the interview, I’m sure, but Eric was a fantastic host.

Thanks again, Eric, for including me in your excellent podcast.

NPOTA activation on the Blue Ridge Parkway

A crowd gathers as Vlado (N3CZ) works station after station in CW!

A crowd gathers as Vlado (N3CZ) works station after station in CW!

I’m not sure what I’m going to do after the National Parks On The Air event is over at the end of this year. I hope the ARRL organizes something equally as fun for 2017.

Truth is, I love playing radio outdoors and I love National Parks. The two are a perfect combo.

My buddy, Vlado (N3CZ), and I decided to do an NPOTA activation on Sunday. The weather was fantastic–a little foggy with mild temperatures and the HF bands were open!

We arrived at our site–the Craggy Gardens Picnic Area (PK01)–at 14:30 UTC or so.

KX3-PK01-NPOTA

We brought the following antennas and supports:

  • a self-contained  20 meter band telescopic fiberglass vertical (I recently purchased at the WCARS Hamfest for $40–!) and
  • a 31 foot fiberglass Jackite pole (the fluorescent orange on in the photos) which we used to suspend a homemade 40 meter doublet Vlado built the day before.

Setup was quick. We were both especially pleased the 20 meter vertical. It was so easy to install, even considering it was the first time either of us had used it.

I powered the LD-11 and the KX3 with my QRP Ranger.

I operated SSB from a picnic table using the LnR Precision LD-11 transceiver, connected to the doublet on 40 meters, and the mono-band vertical on 20 meters.

LD-11-QRP-Ranger-NPOTA-PK01

Vlado started by operating CW with his Icom IC-7000 which was installed in his car, but later moved to the picnic table and logged a number of contacts with the Elecraft KX3.

N3CZ--NPOTA-PK01

We easily logged the number of stations needed to activate the site.

The 40 meter band was hopping and a good path was open into Ohio, Virginia and other surrounding states. The 20 meter band was serving up some excellent QRP DX.

Vlado-KX3

When I moved to the 20 meter band, the noise floor was so low on the LD-11, I thought perhaps the band was dead.  Not so!

LD-11-NPOTA-PK01

It’s hard to believe that with a mere eight watts in SSB  I worked Rhode Island, Texas, Montana, Manitoba, Washington, California and Slovenia from a picnic table on the Blue Ridge Parkway.

Reports on the LD-11 audio were all very positive. I’ve used the LD-11 for eight NPOTA activations this year and can say with confidence that it’s a brilliant & fun little field radio. (FYI: I’ll be publishing a full review of the LD-11 in the October 2016 issue of The Spectrum Monitor magazine.)

Vlado and I are planning on several more activations together this year. Our next one will most likely be at the Carl Sandburg Home-. I can’t wait!

Any other post readers participating as an activator or chaser in the National Parks on the Air event?

After two months in Canada and one month spent catching up on work, I’m pleased to make some time this weekend to activate PK01 (the Blue Ridge Parkway) for the ARRL National Parks On The Air (NPOTA).

I’ll be joined by my good friend, Vlado (N3CZ) on August 28–we plan to set up at the Folk Art Center on the parkway around 11:00 EDT and be on the air by 11:30 EDT (15:30 UTC).

I plan to use the LNR Precision LD-11, QRP Ranger and EFT Trail Friendly Antenna combo. Vlado will either use his Icom IC-7000, Kenwood TS-480 or my Elecraft KX1.

Look for us on the following frequencies:

  • CW: +/- 7031, 14061 kHz
  • SSB: +/- 7286, 14286 kHz

Life has been so hectic after having been on the road for two months–I’m pleased to finally have a moment to play radio in the field again!

October 10: Let’s talk shortwave…and astronomy

PARIdish

I’ve been invited to speak at the Pisgah Astronomical Research Institute (PARI), a non-profit educational radio astronomy observatory (and former NASA tracking station as well as one-time NSA installation), in the mountains of western North Carolina.

I’ll be speaking about shortwave radio, of course–both its technical and cultural aspects–on October 10, 2014, at 7:00 pm EDT.  Afterwards, there will be a tour of the PARI campus, and an opportunity to stargaze with both amateur and professional astronomers.

Many thanks to my buddy, Ken Reitz, who shared this article about my presentation in the area’s local county newspaper; here’s my statement about the presentation:

“Shortwave radio is an international communications medium that has been in existence for nearly one hundred years,” said Witherspoon, “yet this vintage technology supports an ever-evolving multicultural landscape that, remarkably, remains relevant today. The Internet and mobile technologies have made the dissemination of information more readily accessible to many, yet shortwave radio remains viable and dynamic, and in many ways still outstrips the Internet.

“I plan to share some of shortwave radio’s diverse voices and investigate some of the technology used to receive them. So, if you are a shortwave enthusiast, or simply interested in learning more about shortwave, this program is for you and will be suitable for all ages.”

Read the full article here–and if you can make the journey, join us for shortwave and astronomical fun. There is a small charge for the evening; all proceeds go towards PARI’s mission of providing public education in astronomy.

PARI is a stunning radio astronomy campus which will no doubt be accentuated by the mountains’ fall leaf colors on October 10. For PARI’s location, click here.
