What are your favorite portables in 2022 and why?

I’m traveling this morning and packing up my EDC (everyday carry) bag here int he hotel room.

Last night, I was using the Tecsun PL-330 to do a little band-scanning and it dawned on me that I’ve used this radio along with the Belka DX quite extensively this summer while on an extended family road trip. Even before this trip, both of these radios were in heavy rotation.

I go through phases of using portables–sometimes I’ll dig out a vintage radio and use it for weeks, then I’ll switch it out for a modern rig. I like variety and giving all of my radios a little air time.

I packed the Belka DX and Tecsun PL-330 for our trip because they’re some of the most compact, lightweight radios I own.

I’m curious what radios you’re using now and why–? Please comment!

My Perfect Radio Trifecta

by Jack Kratoville

Last Fall, I asked SWLing readers to assist me in my decision as to what portable radio I should take on a two-week trip to Germany. While I came up with an initial list of portables I already own, there were some excellent suggestions on what I might pack. (Sidenote to Thomas – yes, my wife and I packed everything we needed into two carry-on pieces, including my 3 radios. Your expertise continues to serve us well!) To all else, thank you again for your thoughts, suggestions and comments.

The Tecsun PL-310ET was a top choice of many, yet one I had previously never taken into the field. It seemed a logical choice for this trip. The second is the Sangean PL-210 and it just fits in any pocket. The third is a DAB receiver someone had given me, tossed in a drawer, and forgotten about until I realized Germany implemented DAB to replace the MW and LW bands. The only name I can find online is the DAB-8. Being quite small, it made the cut and I shoved it in between a couple of tee shirts.

At our destination, I quickly realized I could not have chosen a better trinity for myself. Here’s why.

Tecsun PL-310ET

If this had been the only radio I brought, I would have been more than satisfied. SW signals abound (the war just two countries away was certainly a factor.) A quick hit of the ETM feature at the top of the hour brought in 40-50 listenable signals, with only a scant few broadcasts religious in nature. Even during the day, I could capture 25 easily. With the bandwidth set at 3 kHz, sound was most impressive. While some were the same broadcast on different frequencies, my only real disappointment was the lack of English-speaking broadcasts – but that was to be expected. The PL-310ET scans relatively fast and holds on to strong signals quite nicely.

We stayed with relatives who lived high on a hill not far from Kiel, in the north of Germany. One push of the ETM feature on FM filled the dial with German voices playing mostly English pop music (the eighties apparently a favorite decade there too.) Simply put, the selectivity on this radio is phenomenal. Odd / even frequencies happily sharing adjacent homes on the dial. And with the pre-emphasis on European FM at 50, the sound from this portable was absolute perfection. As a matter of fact, my first complaint about this radio was a bit of harshness on our over-processed FM commercial stations. In Europe, the audio characteristics of classical, pop, rock and talk stations was simply sweet.

My first night on the AM band was a disappointment. One, maybe two signals that didn’t come in very well. Thankfully, I quickly remembered to flip it to 9kHz and – wow! The BBC, Spanish, Italian, and signals that sounded very much like eastern Europe came booming in. I did not expect all of this and can easily say this was the most fun I’ve had band scanning and DXing in a long, long time! Traveling domestically, I’m more apt to load a memory page, but in this situation, the ETM feature was incredibly useful.

For all DXing, I only used the whip and internal antennas. The battery indicator dropped one notch on the second to the last day we were there. The PL-310ET is an absolute true travel performer.

The Tecsun PL-310ET now sits proudly alongside my CCrane Skywave, Digitech AR1780, Eton Executive Satellit (Grundig edition) and the semi-retired Grundig G5. When we travel to London next year, there’s no question this gets packed again.

Sangean PL-210

A radio that became my constant walking companion during Covid. Hand-sized with a really nice on-board speaker for its size. The sensitivity is impressive and considering its PLL circuitry, has excellent selectivity on FM. AM was also impressive for an antenna no more than a half-inch – if that. It went with me to Hamburg, Berlin, Frankfort and Denmark; always just a quick pull from the pocket for a quick scan. To say I like this radio, well, I own three.

DAB-8

My curiosity in DAB was basically zero. One reader actually PM’d me and offered their own DAB receiver, saying I should check it out. (Thank you, Mike, for that generous offer.) This radio sounds great, but has very poor FM reception. (No MW). It does have inputs for mp3 and Bluetooth, so I figured just in case there was nothing to listen to, I could stream something on it. Its small size was the biggest factor in making the trip. Once settled, a quick daytime scan grabbed nine signals easily on DAB and they sounded great. It was the only band that featured more traditional (even country!) music. It’s back in the drawer at home, but I am very glad it made the trip.

Summary

I truly had a blast listening to the various captures on these three radios, the Tecsun being the most impressive and fun. I’m sure many newer models would be excellent choices, but not once did I wish to have something bigger or better. That doesn’t happen on trips very often, so perfection indeed.

My apologies to those looking / hoping for recordings. I stopped recording from the radio back when I opted to purchase 45rpm records rather than record them, complete with DJ patter on my father’s Webcor reel-to-reel. Once I got into the biz, I recorded enough DJ patter to last a lifetime! Again, thanks to everyone for their input.

The RADDY RF760: Light, Portable, Powerful

(Guest Post)

 By Robert Gulley K4PKM

(Note: This review was requested by Radioddity, who provided the in-production radio to the reviewer, with no strings attached or pre-approval.)

I confess to have been a little bit skeptical when Thomas asked me to review this radio, not because of past experience with RADDY, but because tiny radios in general don’t usually impress me, and I have had plenty of them over the years and considered most of them a novelty. There are a few exceptions, of course, such as the C.Crane Skywave or the Tecsun PL-368, but for the most part there are simply too many limitations to tiny radios for my listening style (this one can literally fit in a shirt pocket!). Upon opening the box I was still skeptical, despite the rather impressive packaging and extras. But hey, a little skepticism is a good thing, right?!

The radio comes with some nice accessories!

Accessories

The radio comes with a thin carry case to protect it from scratches, a rechargeable lithium battery, strap, earbuds and a wire antenna to improve shortwave reception. There is also a Type “C” USB cable for charging the battery. Oh, and a spare set of earbud covers – a nice touch!

Ergonomics

Picking up the radio I noticed right away it has a solid, comfortable feel to the unit. I start with that because most tiny radios feel very flimsy, and usually have something of a rough or hard plastic feel to them. This radio has a glossy feel to it, meaning it is comfortable and actually nice looking. Looks aside, I must admit the ergonomics of the radio impress me. I like the feel of it in my hand, and the controls are laid out well for one-handed operation. Being left-handed, that is not always the case, but the controls seem well thought out for either right- or left-handed folks.

As you can see in the images there are two primary rows of buttons, as well as a tuning knob on the right side of the radio. There is also a belt clip on the back which is unobtrusive – I can’t speak to its longevity as I really never clip a radio to my belt, but for those who do, I suspect it will hold up well with a little care.

The telescopic antenna (fixed) is rather impressive as well, measuring ~18 inches in height when fully extended. As one might imagine, at this length the antenna is fairly fragile – I would not walk around with it fully extended while attached to my belt. For hand-holding it should be just fine, and standing upright on a table it does not tip over, but if out in an open-air environment with a strong breeze it will tip over, so a stand would be advisable.

The display is very readable, and the orange background light which pops on when making adjustments is quite nice. The light stays on for ~9 seconds after pushing any of the buttons. Another nice feature of the radio is a press of any button while the radio is off will turn on the display, indicating time, temperature, and battery strength. Yes, it has a built-in thermometer, and it seems quite accurate, at least on the unit I received.

On top there is an external antenna jack, headphone jack, and slot for the strap.

Operation

For such a small radio it is literally packed with features. I will not go over all of them in this review, but I will cover some of the highlights as well as make mention of most features at least in passing. I was not expecting so many features in this little radio, so I was pleasantly surprised by some of the more advanced options.

Naturally the radio has AM/FM capabilities, as well as weather, air, VHF above the air band, SW and CB (yes, CB!). There is also a customizable frequency range setting for monitoring a desired set of user-selected frequencies. There are presets available for various modes listed in the manual, including predefined amateur radio bands and shortwave stations (always subject to change, of course!).

There is an attenuate function available if needed, as well as numerous step modes for tuning various modes. One interesting feature of the radio is two separate tuning methods, one by up and down buttons, and the other by a tuning knob on the side. These can be set independently of each other in terms of the step-change on a given band. This is particularly useful when scanning a band with the buttons after a station is found, because sometimes being slightly off frequency can produce a better signal – the scroll wheel can be used to make as little as 1 Hz changes.

Finally, there is a very useful bandwidth feature which can change between 3, 2.5, 2, 1.8, 1, and 6 kHz. Tuning is quite functional both with the scroll wheel and the tuning buttons. Holding down the tuning buttons will start a scan of the current band, and a longer press will speed up the scan if no stations are found initially. Unlike some scanning radios, when a signal is found, scanning stops and does not resume. I like that feature better than the alternative method of some radios restarting a scan after 5 seconds or similar. I want time to figure out what I am hearing, and a short stop does not really allow for that most of the time.

This is a very compact and lightweight radio!

Reception

I have to say I am impressed with this little radio. I have listened to amateur frequencies, shortwave frequencies, AM/FM, weather and tried airband (nothing close to me except a minor airfield). I live in a very quiet location in terms of local man-made interference, and this provides a great opportunity to really test out a radio’s sensitivity. My conclusion may surprise you as it did me. This is one sensitive radio, given its small form factor and limited antenna movement. (I did not test the external antenna option. While it has one, I felt it only fair to make tests using the built-in antenna on all the radios I compared it with, thus eliminating extraneous or otherwise hard to compare situations.)

Side by side with one of my favorite portables, the Sangean ATS-909X2, this little guy was right in there with difficult to receive stations. While the Sangean has a much larger speaker and therefore fuller sound, in terms of actual reception, most stations came in about equally. I even used an old, but very reliable Select-A-Tenna to boost AM reception on both radios, assuming the Sangean has a much larger ferrite rod given its size, and yet both performed equally well next to the passive antenna. Impressive!

On various shortwave and amateur stations the RADDY RF760 held its own again, picking up almost station for station what the Sangean and the Sony 7600 GR (another favorite of mine) did, in a package less than 1/3 the size of the Sony, and about ¼ the size of the Sangean. Am I going to dump my Sony and/or my Sangean? Of course not – there are many reasons I prefer those radios for my daily use. But if I were wanting to go extremely lightweight/portable, the RADDY is a keeper with impressive performance and most features one could want in a portable radio, all while still fitting in your shirt pocket. I truly do not know how one could get much better performance or features in another radio this size. It makes one wonder where can they go from here?

FM reception is also quite good, pulling in weaker stations while still being quite listenable. I have heard a few stations on this radio which I have not caught before, and this with some atmospheric noise due to storms in the region. Likewise, listening to AM while there were storms in the general area, still allowed for reasonable reception. As we all know AM broadcasts are highly susceptible to atmospheric noise, especially lightning, but this radio recovered nicely after each static crash. Some radios seem to linger longer in recovery after such events, but this radio was quick to bring back in the signals.

Negatives

In short, there really are not any glaring negatives to this radio, so allow me to point out some little things which are, after all more about personal preference than any deficiency in the radio. Your mileage may vary, as they say.

  • An articulating antenna would be a nice touch, but that might require an increase in size, and likely would make the antenna more susceptible to damage. Many times, being able to bend an antenna this way or that can improve a signal.
  • Changing the frequency steps can be a little fiddly at times, but that’s probably me
  • When powering on, the short press acts like pressing any other button, meaning the light comes on, the time, temp, and battery power indicator displays. A longer press brings up the sleep timer. Two short presses turns on the radio, but not too short of presses. This takes a little getting used to, and I would prefer one longer press to turn on the radio, with the two short presses activating the sleep timer, but that, I know, is getting really nit-picky!

Conclusion

If you are in the market for a small, lightweight, but solid radio – this RF760 is definitely one you should consider. It is so light as to be almost weightless, compact but with easily reachable and useful controls, and has more modes and features than almost any similar radio I have run across. As an old-timer I have to shake my head in amazement at what can be packed into such a small radio these days! This certainly isn’t your grandpa’s transistor radio (and it’s even smaller!). Cheers!

The fertilizer hits the fan radio kit

            1st corollary: Even if anything can’t go wrong, it still will.

            2nd corollary: It will go wrong in the worst possible place at the worst possible time.

            “It’s tough to make predictions, especially about the future.” – Yogi Berra

 The Better Half thinks I am sick, and maybe she is right, but I am unrepentant: I like disaster movies and books. True stories are better than fiction, but I like both, and I am curious about how people, real or imagined, get through whatever Horrible Event faces them.

As I have written before–here, here, and here–that when bad stuff happens, radio can be a really useful tool.

It was a comment from a reader – Rob, W4ZNG – that got me thinking some more about this. He mentioned enduring three weeks without electricity on the Mississippi Gulf Coast as a result of Katrina. So we had a phone conversation about: What do you want in your radio kit bag when faced with a longer duration, more severe regional or national emergency?

Here’s some of the stuff we agreed upon.

Gathering Information

At the most basic level, you want a radio capable of receiving local AM or FM broadcasters, and it would be good to know ahead of time which local stations have local news staffs that can broadcast useful in formation in times of crisis. In addition, if you live in the US or Canada, I absolutely recommend the ability to receive NOAA weather radio. The ability to run off batteries is critical, in case the mains power is out. In addition, a generous supply of batteries, or a means to recharge batteries is in order. If you decide to go with recharging batteries, you need to think about your options now, not when the lights go out.

In Rob’s case, during Katrina, all of the local broadcasters were wiped out. There was a local low-power FM broadcaster who got permission to increase power to 1,000 watts and was broadcasting where to get food and water. There was a New Orleans AM station that was on the air, but all of its coverage was “New Orleans-centric.” After a few days, some local FM broadcaster, working together, cobbled together a station that they put on the air and began broadcasting news. Rob also began DXing AM stations at night to get additional news.

We agreed that shortwave broadcasters were not likely to be very useful in most cases, but a shortwave radio with the ability to hear ham radio single sideband networks might well be.

To scan, or not to scan, that is the question

Another potential source of information are local public agency radio transmissions in the VHF and UHF ranges that could be heard with a scanner. But – and this is a very big but – that depends a lot on whether your local government (first responders, etc.) transmissions are encrypted. You need to check a source like https://www.radioreference.com/db/ to see if Public Safety transmissions in your area are encrypted. If they are, you will be unable to decipher them, no matter what equipment you own. However, an inexpensive analog-only scanner may prove very useful for listening to ham transmissions VHF and UHF (2 meters and 440 primarily) as well as FRS and GMRS.

If your local Public Safety radio systems are not encrypted, the RR database will give the details of the radio systems used by those agencies, and that in turn will determine the level of sophistication of scanner that will be required to hear their transmission.

The Radio Reference database also includes a listing of national radio frequencies including a list of federal disaster frequencies such as might be used by FEMA. In addition, I have found that the folks at the Radio Reference forum are generous with their time and expertise: https://forums.radioreference.com/ . If all this sounds a bit daunting, there are scanners that have built-in databases of all available frequencies and radio systems, and all you need to do is put in your zip code and select which services you want to hear. I own one, they work well, but they are expensive.

Summoning Help

Assuming that the power is out, your cell phone may or may not work (during Hurricane Katrina, some people found that they could not make voice phone calls, but text messages would go through).

If the cell phones are not working, two-way radio may be useful to summon help and gather information. Again, some research on your part is in order. Perhaps there are 2-meter or 440 ham repeaters in your area with backup power, or maybe there is a robust GMRS repeater system. If so, get your ham or GMRS license and start participating! (It was his experience during Hurricane Katrina that prompted Rob to get his ham license, and when Hurricane Zeta hit, he was glad he had it.)

FRS bubble-pack radios are good for staying in touch while getting around the immediate neighborhood.  It’s also good to have a few spares to hand to neighbors if the need arises.  Often on sale (especially after Christmas) in multi-packs for less than $10 each.

Rob notes that great strides have been made in hardening cell phone towers since Katrina.  When Hurricane Harvey clobbered Houston in 2017, the cell net stayed up.  Even so, it would be prudent not to count on it!

The Bottom Line

At a bare minimum the ability to receive your local AM and FM broadcasters is essential, and NOAA weather radio is also very useful. At the next step up, depending upon your local situation, a scanner may help you to gather information. In addition, the ability to monitor ham transmissions may also add to your information gathering abilities. Finally, having a ham license and the ability to transmit on ham frequencies may be very valuable in a widespread or long-duration emergency.

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”

Many thanks to SWLing Post contributor, Jock Elliott, who shares the following guest post:


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.”
