SWL with a Reuter Pocket and the Icom IC-705

by Uli (DK5ZU)

Some time ago I asked how the IC-705 performs on longwave and I got some great feedback. Thanks a lot again. Since the HAM bug bit me again, I wanted to do SWL and HAM Radio portable with one rig. I started with SWL some weeks ago (just before the bug bit). I acquired a second hand Reuter Pocket RDR 51 Version B2. It is a standalone SDR Receiver 0 … 30 MHz / 50 ..71 MHz, and in my B2 version it has also FM (Stereo/RDS) and Digital Audio Broadcasting (DAB). You may find the detailed specs here:
https://www.reuter-elektronik.com/html/pocket.html

The Reuter Pocket could, at one point, be configured as an QRP Transceiver, but it is no longer supported. There is a new RDR 52 small tabletop models, which can be ordered as a transceiver, too. But due to Covid related supply chain problems and price changes for the components, the new model is currently postponed.

The IC-705 is available, though. And for portable HAM operations it is a no brainer; obviously with a high price tag, but comparable with a new Reuter RDR 52 tabletop. And since my budget for the hobby is limited, I thought about funding part of the IC-705 price by selling the Reuter Pocket. But I wanted to do a side-by-side comparison so I ordered the 705 and was able to check them both on one antenna. The goal was to compare their sensitivity and selectivity on the lower bands: BC on AM and HAM bands for SSB. I did not compare CW since I am not a CW operator.

The antenna is a MiniWhip from PA0RDT which works quite well on the lower bands.

This comparison is not at all scientific and reflects just my opinion and what I heard. But anyway, there may be some people out there interested in this. So much for the intro.

Let’s start with my overall findings. Continue reading →

Crystal Radios – Construction, Listening, and Contesting

By David Day – N1DAY

The date was November 2, 1920 and the world was about to change forever when radio station KDKA out of Pittsburgh PA made its first broadcast of election results from the 1920 presidential election. For the first time in history people knew who won the election before reading about it the next day in the newspaper. Radio had arrived!

However, hearing the election results was not as easy as powering up an AM radio receiver because radio electron tubes had only been invented a few years earlier and they were still too expensive for most people to afford in a radio set. After KDKA’s historic broadcast, large 50,000 watt stations began popping up in all major cities around the world. Even though a tube-driven radio was not yet commonplace, many people listened to these stations on their crystal radios. The frenzy around radio in the 1920’s was not unlike the excitement around cell phones and the internet today. If you didn’t have one, you were simply living in the past.

A family listening to a crystal radio in the 1920’s

Fortunately, in the early 1920’s the crystal radio had been around for a while and it was easy to make or purchase a completed set on a limited budget. The beauty of the radio was that it was a passive device needing no power source other than the radio station’s broadcast that was received by a good antenna about 50 feet long and 15 or so feet above the ground. Crystal radios derived their name from use of galena crystals as detectors. Continue reading →

DX Central’s MW Frequency Challenge: Week 9 Results and Week 10 Announcement

2 Replies

Many thanks to SWLing Post contributor Loyd Van Horn at DX Central who shares the following announcement:

Another great week in the MW Frequency Challenge, and you all continue to pour the logs in! Our live streams on Saturday nights have been so much fun getting to interact and hear about what you heard in the previous week. If you haven’t been able to make it to a livestream yet, you are missing out! Join us Saturdays at 1945 CST / 0145 UTC (Sunday morning, UTC) on our YouTube channel: youtube.com/c/dxcentral

A total of 29 DXers from three countries (Mexico, Canada and the US) and 17 US States brought in 82 logs for Week 9 of our MW Frequency Challenge. 25 unique stations in 18 states and six countries made it to this week’s log. The number of logged stations was down, because there are fewer stations on 550 than previous weeks. But look at that jump in countries…an opportunity here for DXers to get some great international DX!

Most Logged Stations: From runner-up last week to the top spot this week, South Carolina’s Rob Keeney hauled in an impressive 9 stations this week. Right on his heels, was Mark Connelly (MA) and Stephanie Battaglino (CA) with 7 each.

Most Logged States: Rob Keeney once again took the top spot for heard states this week with 7 logged US states: FL, GA, MO, NC, NY, OH, TX

Most Logged Countries: Mark Connelly (MA) brought in the most countries (including US) with 4 total countries: Colombia, Cuba, US, Venezuela.

Furthest Logging: Brent Taylor of Canada’s Prince Edward Island and his log of YVKE-Radio Mundial in Venezuela was our longest reception of the week at 2,477 miles! This was only 5 miles more than the #2 spot, Mark Connelly’s 2,472 mile reception of HJHF-Radio Nacional de Colombia in Colombia. Even tighter, Mark’s log was only ONE MILE more than our third place finish from Marc DeLorenzo for his log of HJHF at 2,471 miles! Talk about a close one! Rounding out our top 10 was Jim Renfrew (NY) – 2,358 miles for YVKE, Mark Connelly (MA) – 2,163 for YVKE, Rob Keeney (SC) – 2,034 for HJHF, Brent Taylor (PEI) – 1,962 for WPAB, Mark Connelly (MA) 1,531 for Radio Rebelde, and Stephanie Battaglino (CA) – 1,094 for KTSA.

Loyd/DX Central Numbers:

5 stations logged
3 states logged (GA, MO, TX)
3 countries logged (USA, Cuba, Colombia)
1,926 miles for furthest catch (HJHF in Colombia)

Most Logged Station: WGY in Buffalo, NY brought in 10 logs this week for the top spot. Missouri’s KTRS and Cincinnati’s WKRC at 7 logs each were just behind them.

Most Logged State/Province: As you might imagine, WGR’s logs brought NY to the top spot here with 10 receptions. NC (9) and TX, MO (8 each) were just behind.

Most Logged Country (outside of US): Colombia and Mexico each brought in 4 loggings this week. Cuba and Venezuela (3 each) were just behind. In all, 15 stations outside of the US were logged this week.

Busiest Time of Day: Overnight hours (67% of logs) continued to be the busiest period for DX. Surprisingly, sunrise was in the second spot with 14.6% of all logs. Sunset (11%) and Daytime (7.3%) rounded out the rest of the day.

Most Used Receiver: While portable use is still going strong, SDRs once again were the king of DX this week with 56 of 82 logs (69%). Portables brought in 20 logs (24%) of all loggings. Among SDRs, we actually had a new brand at the top of the hill as Airspy SDRs brought in a total of 22 loggings (40% of all SDR logs). SDRPlay’s 18 logs (32% of SDR logs) and Perseus’s 13 receptions (23% of SDR logs) were also very popular this week. For portables, Tecsun’s came out of nowhere this week to take the top spot with 9 loggings (45% of portable logs). C. Crane radios (4 loggings, 20% of portable logs) took the #2 spot.

Most Used Antenna: Magnetic Loops were once again the most popular option for DXers this week, with 32 logs (40% of all logs). The Wellbrook loop’s 21 loggings (65% of all mag loop logs) were the most popular used mag loop, with both the W6LVP and YouLoop (9 logs each, at 28%) also bringing in DX. Termed loops proved to continue to be a popular option as well, with 17 loggings (21% of all loggings). This week, other loops (such as the AN-200 or Tecun loops) also brought in 17 loggings this week as a popular option.

See the full export of data at our Google Sheet: https://docs.google.com/spreadsheets/d/1OGMctuhKyj3lIxqd6tv9oxw2WhZ3F7Q7qM7TGnOxPak/edit?usp=sharing

With week 9 now under wraps, we look ahead to week 10 and for this week, we have a rather unique challenge. Rather than focus on a single frequency, we are going to explore the ENTIRE expanded band! 1610-1710 kHz – any licensed station (including broadcast and TIS) count as a valid log. No pirates, no NDBs, etc. So the NJ TIS station on 1710? Counts. 1630 Radio Elohim in El Salvador? Counts. The “TVS” NDB on 1650? Does not count.

With 11 frequencies to contend with – even with much fewer stations per frequency – this should be our largest week yet!

Our Google Form for Week 10 can be found here: https://forms.gle/41FNE9F81bhCr4ts6

RULES:

Logs for Week 10 will only be accepted for stations received between 0300 UTC Sunday, January 23, 2022 and 0300 UTC Sunday, January 30th (will be announcing the closing during our live stream of DX Central Live!). Logs must be for licensed stations received between 1610 and 1710 kHz. This includes all standard broadcast stations in the US and internationally, as well as any TIS stations received. Logs must be from your own equipment using WebSDRs is allowed for reference, but will not be counted towards the challenge (unless it is YOUR WebSDR). If you do log from a WebSDR, be sure to mark your location as from the location of the WebSDR itself, not your home location. All loggings must be submitted using our Google Form at https://forms.gle/41FNE9F81bhCr4ts6 Submissions by any other form including social media, email, etc. will not be accepted.

An eCertificate will be sent to the DXer with the most logged stations during the challenge time period. Additional eCertificates may be presented at the discretion of DX Central.

Have fun, 73 and best of DX!

DX Central’s MW Frequency Challenge: Week 8 Results and Week 9 Announcement

5 Replies

Many thanks to SWLing Post contributor Loyd Van Horn at DX Central who shares the following announcement:

Another great week of loggings in our MW Frequency Challenge is in the rear view mirror, with week 8/1460 kHz closing out last night during our DX Central Live! livestream.

We now turn our attention to a new frequency for week 9: 550 kHz.

This will be a challenging frequency, as there are not as many stations here. There are opportunities though for both domestic and international DX, and US stations have a decent amount of space between them and a good smattering of 5kw stations to make this week one that should be a lot of fun!

We are already getting in some good logs from those that were on the livestream last night, be sure to get your logs in as well using the Google Form linked in the blog post, below.

The new Xiegu X6100: Is it a good SW/MW broadcast band receiver?

7 Replies

Late last year, Xiegu started shipping their latest portable rig: the Xiegu X6100.

The X6100 is an all-in-one QRP SDR field transceiver. It sports an internal antenna tuner, internal Li-Ion rechargeable battery pack, and even an internal mic for hams who don’t want to carry the supplied mic to the field. For field operators, it’s in the very desirable “shack in a box” category. Just hook up an antenna and you’re on the air.

The X6100 got a lot of attention in the ham radio market because in many ways it resembles the Icom IC-705.

The X6100 sports top-mounted controls, a beautiful high resolution color display, and front-facing speaker. At $630 US, it’s less than half the cost of a new IC-705.

As with pretty much all modern SDR transceivers, the X6100 has variable filters and a general coverage receiver. The X6100’s receiver has gapless coverage from 0.5 MHz to 30MHz and 50MHz to 54MHz, thus covering the mediumwave and shortwave broadcast bands.

Radioddity sent me a loaner X6100 that I took delivery of on December 23, 2021.

Literally, the first thing I did was tune it to the 31 meter broadcast band.

While I’ve spent the bulk of my time with the X6100 in the field testing it as a QRP transceiver, in the shack I’ve done a fair amount of SWLing both in AM mode and (pirate radio stations) in SSB mode.

My assessment

I’ve received a number of inquiries from SWLing Post readers about the X6100 asking how it stacks up to the IC-705 from an SWL’s perspective, so I thought I’d share my impressions so far to help guide any potential purchase decisions. I’ll provide much more detail in my upcoming review in The Spectrum Monitor magazine (likely in March or April 2022).

In short: I would not buy the Xiegu X6100 specifically for shortwave broadcast listening.

While the frequency coverage is ideal, the variable filters are useful, and the color spectrum display and waterfall (in terms of the interface) are benchmark, the radio has a few cons from an SWL perspective:

I have noticed imaging on the spectrum display as I tune through the broadcast bands (shortwave and mediumwave). I seriously doubt this is something that can be addressed in firmware.
The X6100 does not have a robust front-end. A number of my readers on QRPer.com who live near strong broadcast stations have noted that it’s almost unusable from home.
The audio is typical of Xiegu radios, meaning it’s unrefined and a bit harsh. I find it a bit fatiguing over extended listening sessions both using the internal speaker and headphones.

In fairness, the X6100 wasn’t designed with the SWL in mind.

With the negatives out of the way, the X6100 is very much a usable radio for casual broadcast listening. You might even be able to push it into a little DX action as well. If you plan to purchase the X6100 for ham radio activities anyway, consider broadcast listening as a bit of “icing on the cake.”

X6100 vs. IC-705 from an SWL’s perspective

I’ve been asked specifically about how the X6100 compares with the IC-705 in terms of shortwave and mediumwave listening.

There’s really no competition: the IC-705 is better than the X6100 by orders of magnitude in this regard.

The IC-705 is a high-performance radio with receiver qualities that would please most serious DXers. (Check out some of 13DKA’s reports!). That level of RX performance and filtering comes with a $1,300 US price tag.

The X6100 was designed to be price-competitive and to have ample performance and a tool set to please the low-power ham radio field operator. I feel like it’s a success in this regard. When I’m in the field performing a park or summit activation, I’m typically far removed from urban RFI and blowtorch broadcasters. The field operations I’ve performed so far with the X6100 (mostly in CW/Morse Code) have been quite successful and enjoyable.

I hopes this helps! Again, I’ll have more detail about the Xiegu X6100 in my upcoming detailed review in The Spectrum Monitor magazine. If you’re interested in how the X6100 performs as a QRP transceiver in the field, check out my reports on QRPer.com.

Thank 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 David Iurescia, Mark Erdle, and the Southgate ARC for the following tips:

Voice heard ’round the world: Voice of America museum near Cincinnati a historical marvel (The Columbus Dispatch)

WEST CHESTER, Ohio — Imagine, if you will, a voice so strong that it shakes the very foundations of global tyranny.

In the early days of World War II, a group of Americans, including President Franklin Roosevelt, actor and director John Houseman and Cincinnati entrepreneur Powell Crosley Jr. imagined such a voice, one that could counter Nazi propaganda in Hitler’s own backyard.

They named it The Voice of America.

Today, the National Voice of America Museum of Broadcasting, 8070 Tylersville Road, occupies the site from which the service beamed its message around the world for 50 years beginning in 1944, recounting its history and remembering the people, especially Crosley, who made it possible.

100th Anniversary Celebration of the First Trans-Atlantic Radio
Transmission of a Message by Amateur Radio (1BCG.org)

Saturday, December 11, 2021

On a cold winter night on December 11, 1921, members of the Radio Club of America were able to send the first amateur radio message from a small shack in Greenwich, CT to be received by American Paul Godley in Ardrossan, Scotland. This transatlantic test proved the value of shorter wavelengths – long considered worthless to long distance communications and through their success ushered in the age of global shortwave radio communications. The 1921 message was sent one-way. Acknowledgment of Paul Godley’s reception of 1BCG’s massage was sent back to the US via the Marconi high power radio transmitter in Wales.

The Antique Wireless Association, in association with the Vintage Radio and communications Museum of Connecticut (VRCMCT) in Windsor, CT, the Radio Club of America, the American Radio Relay League, and the Radio Society of Great Britain, participated in the 100th Anniversary special events held Saturday, December 11, 2021.

For the 75 th anniversary celebration of the 1BCG accomplishment in 1996, AWA members Bob and Mike Raide constructed a replica of the 1921 transmitter. For this 100th celebration, AWA Museum Staff restored the replica. The VRCMCT in Windsor CT has graciously offered to host AWA operation of the replica transmitter during the evening of December 11th. The 1BCG replica transmitter was placed on public display at the VRCMCT Museum during the day of Saturday December 11, 2021. [Continue reading the full report at the 1BCG website…]

Celebrations to mark the BBC’s Centenary began at midday today (1/1/2022) via shortwave radio (Southgate ARC)

BBC Radio 4 announcer/newsreader, Jim Lee, launched special event amateur radio station GB100BBC, from the BBC’s Broadcasting House, in London, at exactly midday.

Listen to the broadcast:
GB100BBC launches 1st Jan 2022
With thanks to the London BBC Radio Group

Within minutes amateur radio stations around the UK and throughout Europe were clamouring to contact the special BBC station and secure a prized entry in the logbook.

The London BBC Radio Group was granted an extended special event radio licence by the regulator OFCOM, to operate the station throughout 2022.

The amateur radio activity is one of many events organised to celebrate 100 years of the BBC, which began broadcasting from Savoy Hill in 1922 as the British Broadcasting Company, moving to the iconic Broadcasting House in 1932, gaining a Royal Charter as the British Broadcasting Corporation.

The London BBC Radio Group has a growing membership which includes engineers, journalists, producers and on-air talent in both TV and Radio. The group is independent but hosted and supported by the Corporation.

The group was launched in 2017 by a handful of radio enthusiasts to revive a long and rich history of amateur radio at the BBC dating back to the Second World War.

The ‘radio shack’ at the BBC’s headquarters, Broadcasting House in central London, was officially opened by the then Director General, Lord Tony Hall, with an over-the-air message of congratulations. Lord Hall was subsequently bestowed Honorary membership of the club. [Click here to read at the Southgate ARC…]

Czech radio switches off MW and LW as 2022 starts (Mike Terry via the Southgate ARC)

Prague (dpa) – Radio reception on medium wave (MW) and long wave (LW) has been history in many parts of Europe for years.

Now, in the Czech Republic, at least the public broadcaster will stop transmitting on MW and LW as the new year starts on Saturday.

The powerful transmitters on the frequencies 270, 639 and 954 kilohertz could also be received in large parts of Germany.

The reason given for the move was the widespread availability of terrestrial digital radio DAB+ and the high costs of broadcasting.

Those still listening using medium waves were to be persuaded to switch with a campaign. The radio station Cesky Rozhlas set up a telephone hotline to answer questions.

It was not known at first whether the transmitters would be retained or used for other purposes.

The antenna of the medium-wave transmitter Liblice B east of Prague is considered the highest structure in the Czech Republic, with a height of 355 metres.

Impuls, the most-listened to private radio station, wants to remain faithful to medium wave for the time being. It broadcasts its second programme, with pop and country music, on analogue transmission.

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

63 Replies

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.
