Matt’s Rooftop Receiver Shootout: Round Two!

Many thanks to SWLing Post contributor, Matt Blaze, for the following guest post:

Matt’s Rooftop Receiver Shootout, Round Two.

by Matt Blaze

You may recall that back in April, I dragged eight of my favorite receivers up to the roof, hooked them up to a portable antenna, and compared their abilities to demodulate various signals at the same time. For the most part, the similarities between radios were more striking than their differences. I hinted that there’d be a second installment to come, including more receivers and more challenging signals, to further expose and highlight the practical real-world performance differences between the radios we use.

So, as promised, here we are with Round Two of my Rooftop Receiver Shootout.

This time around, I used approximately the same setup, but with a total of fifteen different radios. And once again, I took advantage of nice weather and brought a multitude of receivers, recording gear, cables, and an antenna up to my roof to listen to and record shortwave signals under the open sky.

Our fifteen receivers included everything from “dream radios” from the 1980’s to current-production desktop models to less expensive modern portables to high-performance bench-top lab measurement gear. I tried to curate samples of a wide range of radios you may be familiar with as well as some you probably aren’t.

The lineup consisted of:

Icom R-8600, a current production “DC to Daylight” (or up to 3 GHz, at least) general coverage communications receiver, with highly regarded shortwave performance.
AOR AR-ONE, another DC to 3 GHz general coverage radio, less well known due to the high price and limited US availability. Excellent performer, but a counterintuitive and awkward (menu-driven) user interface is less than ideal for shortwave, in my opinion.
Reuter RDR Pocket, a very cute, if virtually impossible to get in the US, small production, high performance SDR-based shortwave portable receiver. It’s got an excellent spectrum display and packs near desktop performance into a surprisingly small package.
AOR 7030Plus, an extremely well regarded mobile/desktop HF receiver from the late 90’s. Digital but retaining some important analog-era features like mechanical filters. Designed and (mostly) built in the UK, it’s got a quirky menu-driven user interface but is a lot of fun once you get used to it.
Drake R8B, the last of the much-beloved Drake receivers. Probably the chief competitor to the 7030+.
Drake R7A, an excellent analog communications receiver (but with a digital VFO) from the early 80’s. It still outperforms even many current radios.
Sony ICF-6800W, a top of the line “boom box”-style consumer receiver from the early 80’s. Great radio, but hard to use on SSB, as we saw in Round One.
Panasonic RF-4900, the main competition for the Sony. Boat-anchor form factor, but (improbably) can run on internal D-cell batteries. Generally impressive performer on AM, but, like the Sony 6800, difficult to tune on SSB.

You may remember the above radios from Round One back in April. The new radios this time were:

Tecsun 501x, a larger-format LW/MW/HF/FM portable released last year. As noted below, it’s a generally good performer, but regrettably susceptible to intermod when connected to a wideband external antenna (as we’ll see in Part One).
Tecsun PL-990x, a small-format portable (updating the PL880), with many of the same features as the 501x. Like the H501x, good performance as a stand-alone radio, but disappointing susceptibility to intermod when fed with an external antenna.
Sangean ATS-909x, a recent LW/MW/HF/FM portable with a good reputation as well as a few quirks, such as only relatively narrow IF bandwidth choices on HF. Excellent performance on an external antenna.
Sangean ATS-909×2, an updated, current production version of the ATS-909x that adds air band and a few performance improvements. Overall excellent, though I would prefer an addition wider IF bandwidth choice. My go-to travel receiver if I don’t want to take the Reuter Pocket.
Sony ICF-7600GR, a small-format digital LW/MW/SW/FM portable introduced in 2001 and the last of the Sony shortwave receivers. Showing its age, but still competitive in performance.
Belka DX, the smallest radio in our lineup, made in Belarus. You’ll either love or hate the minimalist interface (one knob and four buttons). If you’re going to secretly copy numbers stations in your covert spy lair, this is a good radio to use. Can be difficult to obtain right now due to sanctions.
Finally, a bit of a ringer: the Narda Signal Shark 3310, a high performance SDR-based 8.5 GHz RF spectrum and signal analyzer. As with most test equipment like this, demodulation (especially of HF modes) is a bit of an afterthought. But it has an excellent front end and dynamic range, intended for identifying, extracting, and analyzing weak signals even in the presence of strong interference. Not cheap, but it’s intended as measurement-grade lab equipment, not consumer gear. Demodulated audio is noticeably delayed (several hundred ms) compared with other receivers due to the multi-stage DSP signal path.

The antenna was my portable “signal sweeper” Wellbrook FLX-1530 on a rotatable tripod, using a power splitter and a pair of Stridsberg Engineering 8-port HF distribution amplifiers to feed the fifteen radios. So every radio was getting pretty close to exactly the same signal at its RF input. Continue reading →

Guest Post: Everyone should have a “Crisis Radio”

The Crisis Radio

By Jock Elliott, KB2GOM

Sooner or later, it will happen to you. What’s ‘it’? Short answer: a crisis.

It could be as simple as you wake in the morning to find the power is out; you don’t know how long it has been out, and you don’t know when it is coming back. It might be a weather event: a blizzard, a sandstorm, a tornado, a derecho, a hurricane. It might be a geologic event like a tsunami, earthquake, or even volcanic activity. As recent events have shown, it could even be a war or a revolution.

When normal life is disrupted, and uncertainty is perched on your shoulder like a vulture, you will want to know what’s going on, and your usual means of getting information – telephone, smart phone, internet device – may also be disrupted.

When that happens, radio can come to your rescue. Your local FM or AM (medium wave) station may be on the air, providing vital information to your community, or NOAA Weather Radio may be providing hazard information. In extreme cases, shortwave radio may be beaming information to your area when all else fails.

One of the points that was made when our own Thomas Witherspoon was interviewed recently was that people tend to regard shortwave radio as “crisis” radio.

So I have a couple of very specific recommendations.

First, make sure that your household has a “crisis radio.” By that I mean one that will receive your local AM and FM broadcasters as well as shortwave radio, and, if you live in the US or Canada, NOAA Weather Radio. If you can afford it, I recommend getting a crisis radio that has single sideband capability (SSB) so that you have the ability to intercept ham radio communications, which might be another source of information.

Toward that end, I can heartily recommend the CCrane Skywave SSB radio. (Let’s be clear: I have no commercial connection with CCrane; I get nothing from them for making this recommendation, I purchased my Skywave SSB with my own money.) It has AM, FM, Shortwave, Weather, VHF, Aviation and SSB Bands. It is very small, measuring just 4.8″ W x 3″ H x 1″ D and weighing just 6 ounces without batteries. It will run for over 50 hours on a couple of AA batteries and comes with CC Earbuds, SkyWave SSB Carry Case, and CC SW Reel Antenna which boost sensitivity for shortwave and ham radio listening.

It is a crisis radio that you can stick in your pocket, backpack, purse or briefcase for deployment when the need arises or you simply want to listen to some radio programming. Further, you don’t have to be an expert to operate the CCrane Skywave SSB. Thanks to the Automatic Tuning System, just select the band you want to listen to, press and hold the ATS button for two seconds, and the Skywave SSB will automatically search for stations in that band (AM, FM, Shortwave, etc.) and store those stations in the memory banks for that band. You can later check those memories to hear what programming those stations are broadcasting.

Second, and this is important, if you listen to shortwave radio at all, take the time to let the stations know. Drop them a postcard; shoot them an email, do whatever you can to inform them you are listening, and you value their transmissions.

Why? Because we all want those stations to be there if and when the next crisis happens. And if your local AM or FM station provides special programming to the community a weather event or geologic emergency, for the same reason, be sure to let them know how much you appreciate their efforts.

As a fire captain observed a couple of years after the North Ridge earthquake in California: “You cannot be over-prepared for communications in an emergency.”

eBay Find: A “near mint” Sony ICF-6000W PSB/FM/AM band receiver

12 Replies

Many thanks to SWLing Post contributor, Dan Robinson, who shares a link to this Sony ICF-6000W he found on eBay:

The seller notes that the condition is “near mint” and the radio works perfectly both electronically and mechanically.

I absolutely love the design of this radio. When this was being produced (assuming sometime in the 1980s), Sony and Panasonic’s aesthetic smacked of utility, simplicity, and had a near military-grade feel. Ever function had a switch or knob.

Neither Dan nor I have ever seen this particular model before. If I had money to burn, I’d buy it in a heartbeat. Sony radios of this era tended to have stellar AM/MW performance. I’d love to see how large the ferrite antenna inside might be.

Note that even though this radio may work perfectly–it’s obviously been very well taken care of–you would need to mentally allot funds to have it re-capped at some point soon (Vlado could do this, I’m sure). You wouldn’t want a leaky cap to damage the board or other components inside. With radios pushing 40 years old, you must plan to replace the capacitors.

The price is $399 US with a modest shipping fee. The seller has stellar ratings and there’s a 30 day return window .

If you own or have owned an ICF-6000W, we’d love to hear your thoughts about its performance! Please comment!

Guest Post: Comparing the Reuter Pocket and the Icom IC-705 from an SWL’s perspective

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 →

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.

How about you?

The Essential Listening Post

By Jock Elliott, KB2GOM

Listening to shortwave radio (or any radio, for that matter) is just plain fun.

So what do you need to get in on the fun?

A radio. With today’s crop of portable SW radios, many of which have search and store capabilities, a newbie SWL can get started quickly without a lot fuss and bother and no extra stuff. Just hit the search and store function (it has different names on different radios), let the search function do its thing, and step through the memories to see what’s out there. If your radio doesn’t have search and store, you can just tune around to see what’s currently broadcasting or, if you have a computer or smart phone, use it to explore one of the online directories like https://shortwaveschedule.com/

What follow next are some things that I’ve found increase my enjoyment of SWLing. Continue reading →
