Looking back: What radios did you use the most in 2021?

I’m not sure why, but near the end of the year I always like to look back at my radio routine and figure out which radios I used the most. Often, the answer is surprising.

This year, I realized there was a very clear winner…

The C.Crane CCRadio3

The C.Crane CCRadio3 has taken lead position as my daily driver. I have it turned on most days for as much as 4-5 hours at a time depending on how much I’m at home.

Here’s why it has become my daily driver:

Benchmark AM/FM reception: The CCRadio3 grabs a solid lock on my favorite local and regional MW and FM stations. At the end of the day, my favorite news program (Marketplace) is available on a local WCQS and distant WFAE. The CCRadio3 can lock onto both equally well. I’ve very few portables that can do this. In addition, I use the CCradio3 for casual MW DXing when I’m not using the Panny RF-2200 or my Chuck Rippel-restored SRII.
Audio: The audio from its internal speaker is superb for voice content, but also robust enough for music. I love the dedicated Treble/Bass controls. The audio can be turned up to the point that it can be enjoyed throughout our house.
Bluetooth: I listen to a lot of content online and pipe it via Bluetooth from various devices to the CCRadio3. I stream the CBC, FranceInfo, ABC, and/or the BBC most mornings from my laptop. I use Radio Garden on my iPad to explore a world of local radio. I also stream Apple Music from my Mac Mini to the CCRadio3. When I do workouts on my stationary bike, I’ll often listen to both podcasts and music on the CCRadio3 via my iPhone.
Battery life: The battery life on the CCRadio 3 is simply stellar. It takes four D cells which offer up a lot of capacity. There are so few digital display radios today that can quite literally play for a few months on one set of batteries. I invested in a set of EBL D Cells and Charger (this package–affiliate link) and have been super pleased. When in the shack/office, the CCRadio3 is plugged into mains power via the supplied AC adapter. All other times, it runs on rechargeable battery power.

It’s ironic, too, because the CCRadio3 doesn’t cover shortwave which is, without a doubt, my favorite band. Thing is, now that so many of my staple news sources are difficult to reliably get on shortwave in the mornings (oh how I miss Radio Australia) I turn to FM and online sources for news content. I still listen to the BBCWS, RNZ, RRI, and at least a dozen other news programs on shortwave, but due to my schedule, it’s mostly casual listening.

On the go: The Belka-DX

Speaking of shortwave, though, the portable I’ve used the most this year for SWLing has been the Belka-DX. Besides it being a super-performing DX machine, it’s also incredibly compact and portable. I keep it in a small Tom Bihn zippered pouch and it lives in my EDC bag which accompanies me on all errands and travels.

The Belka-DX is so small, I forget it’s there. Even some of my smallest compact portables are nearly three times the size of the Belka-DX.

In the field: The Icom IC-705

If you follow QRPer.com, you’ll no doubt see that I spend a lot of time in the field doing QRP amateur radio activations of summits and parks. As I’ve pointed out in my review and 13DKA has pointed out in his reviews, the IC-705 is a benchmark shortwave, mediumwave and FM DXing machine. At $1300 US it’s pricey for sure, but it offers up a usable spectrum display/waterfall, audio RX controls, customizable filtering, HF/VHF/UHF coverage, and built-in audio recording/playback.

You don’t even need a 13.8V power supply with the IC-705 as it’ll charge from most any USB source via a Micro USB plug and run in receive for at least 5 hours without needing a recharge. Of course, you could invest in a second, higher-capacity battery pack and get even more battery life.

When I take the IC-705 on a field activation, I’ll often do a little listening after I finish the ham radio portion of my outing. It’s a great reminder of how important it is to take your radios to the field these days. With no QRM, it’s amazing what you can receive.

How about you?

Radio Waves: Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers. To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Dan Srebnick, the Southgate ARC and Geneva Witherspoon for the following tips:

Signal of strength: Eiffel Tower celebrates a centenary of radio broadcast (RFI)

A hundred years ago this week, France’s most famous landmark, the Eiffel Tower, was first used as an antenna for radio programmes. Looming high above the city’s uniform skyline, the tower was an obvious choice to pioneer public radio in France, proving the country’s prowess in broadcast technology.

On 22 December 1921, just three years after the end of WWI, “Radio Tour Eiffel” broadcast its first ever show, a live performance featuring legendary singers.

The trial was the beginning of a long series of broadcasts that continues today, with 45 television stations and 32 FM stations – including RFI – broadcasting from the Eiffel Tower.

According to the Lille-based publication Le Réveil du Nord of 24 December 2021, “a concert by wireless telephony took place at the Lille Theatre”.

Famous artists of that era, the legendary Sacha Guitry, the soprano Jeanne Hatto, the tenor Maurice Dutreix and others sang in a microphone in a room in the Eiffel Tower, from where it was broadcast to a “wireless phone set” in the hall of the Lille theatre.

“A large audience attended this session,” according to the dispatch. [Continue reading…]

New Reuter Elektronik RDR52 QRP general coverage transceiver

7 Replies

Many thanks to SWLing Post contributor, Dave Zantow, who notes that Reuter Elektronik recently introduced their latest radio: the RDR52 QRP Transceiver.

Here’s the announcement from the Reuter Elektronik website:

RDR52 in standard “black” and special “metal”

The RDR52 can basically be seen as a desktop version of the popular Reuter Pocket mobile device. Astonishingly, the Pocket is often used as a full-fledged desktop receiver. Many operators report that they have sold their “large” devices and now only use the Pocket because it pairs good reception properties with simple operation and offers a very effective spectrum display while keeping the power consumption to a minimum.

However, the battery-powered Pocket was never designed for that purpose. First, it needs a stand-up aid to be easy to operate on your desktop (display almost vertical). Second, the playback volume of the loudspeakers is low and turning the scroll wheel feels finicky. Third, operation on a constant charging current supply is suboptimal for the built-in batteries: Constant full charging shortens their service life.

The RDR52 avoids these disadvantages. It essentially contains the circuit and thus the display and reception properties as well as the operating options of the Pocket. Due to the larger housing (heat dissipation) and a slightly higher possible current consumption (no batteries as power supply), improvements in the IM behavior (more powerful preamplifiers and AD converters) could be achieved. Other differences to the Pocket include:

- Aluminum profile housing 190 x 90 x 100 mm³ with 5 mm thick front and 2 mm thick rear panel, powder-coated / anodized.
- BNC sockets for antenna connection, separate for 0 – 71 MHz, FM / 2m / DAB and exciter / QRP transmitter.
- Large rotary knob with solid optical rotary encoder.
- Additional rotary knob for volume adjustment of headphones and loudspeakers.
- Two 32 mm loudspeakers with good bass reproduction.
- External power supply DC voltage 9 – 15 V (common hollow pin socket with 2.5 mm pin).

All the Pocket’s enhancements are also available for the RDR52 (broadband spectrum with up to 52.6 MHz display width, 8 different FM filters for extreme DX to high-end stereo, up to 16 GBit flash memory for audio or I/Q recordings, screen dump of the display to the recorder, WiFi, Bluetooth, power supply and control of the RLA4 / RFA1 directly from the antenna input, …). Two basic hardware versions will be available: Standard black with simple loudspeakers and plastic knobs, or a special version with metal knobs and aluminum loudspeaker membranes.

The equipment of different transmitter modules and frequency ranges has been a bit expanded in contrast to the Pocket. Two modules can be installed in the RDR52 at the same time (Pocket: only 1 module). This means, for example, that the FM module and the SW QRP transmitter can be installed at the same time, or the broadband exciter can be installed without the need for an FM module. However, equipping both transmitter modules (exciter and QRP transmitter at the same time) is not possible.

The RDR52 is in production and is expected to be available from the end of December 2021. Prices according to the current price list.

Based on the price list, it appears the RDR52 will start at € 999 with a number of optional upgrades/configurations.

Thank you for the tip, Dave!

The uSDX/uSDR QRP transceiver (Chinese version)

Radio Waves: Stories Making Waves in the World of Radio

Ham Radio SSB Transceiver Fits in Pocket (Hackaday)

Talking about this Chinese ham radio transceiver requires a veritable flurry of acronyms: HF, SSB, QRP, and SDR to start with. [Paul] does a nice job of unboxing the rig and checking it out. The radio is a clone of a German project and provides a low-power radio with a rechargeable battery. You can see his video about the gear below.

SSB is an odd choice for low power operation, although we wonder if you couldn’t feed digital data in using a mode like PSK31 that has good performance at low power. There are several variations of the radio available and they cost generally less than $200 — sometimes quite a bit less.

There isn’t much on the front of the radio. There are a few buttons, a rotary encoder, and an LCD along with a speaker and microphone built-in. There are ports for power to run the radio if you want to not use the battery and a separate port for battery charging. There are also ports for a key, external microphone and speakers, and audio connections that look like they’d work for digital modes. According to commenters, the radio doesn’t have an internal charging circuit, so you have to be careful what you plug into the charging port. [Continue reading…]

(SIDE NOTE: I have been testing one of the USDX / USDR transceivers (a Chinese version–not the open source homebrew project) over at QRPer.com and have been very displeased with performance. So much so, I returned it for a refund. One of the biggest issues being spurious emissions that were produced in harmonics, but also the receiver is one of the worst I’ve ever tested. -Thomas) Continue reading →

Large archive of CW off-air recordings from Italy

2 Replies

Many thanks to SWLing Post contributor, LUIGI Ciampoli (IZ4KBW), who writes:

Some time ago with a friend of mine I created a very big archive of CW QSO recordings available for everybody who want to listen to CW traffic. The idea was born by the need to give to newcomer HAMS material to train on real CW traffic on the bands (with QSB, QRN, QRM, etc.).

So we started to record our ragchewing, ordering files with date/calls of participants/frequencies/keys used and WPM speed of QTC. At the beginning it was not a serious matter, but nowadays the archive counts thousands of records with local and international radio friends…hours and hours of “swinging morse code.” Some of these QSOs are made with ex professional RT involved on radio ham bands spending time talking about the past golden era and having QSO with OMs on the radio.

We released this large archive of recordings in a Google drive folder that can be shared. The archive is located at the following link : https://drive.google.com/drive/folders/1XaF3Mvwa6WvgOCzZjp0NwzgnYdNHsW2Q

Thank you for sharing this, Luigi! What a wonderful idea. I think I will approach you about adding a few of these to the Shortwave Radio Audio Archive as well as there are very few ham radio CW recordings.
