Портативные приемники

Начнем с портативных приемников, потому что считаю, что вы получаете наибольшее значение и качество в ценовом классе за 100-150 долларов. Кроме того, большинство новичков хотят радио, которое включает в себя все необходимое для немедленного выхода в эфир - все эти радиостанции делают именно это. Прямо из коробки, у вас будет все, что вам нужно, чтобы слушать короткие полосы. Все эти предлагаемые радиостанции предназначены для легкого захвата основных коротковолновых вещателей и содержат следующие функции: хорошее частотное покрытие; схема, которая помогает радио обнаруживать слабые станции; и возможность прослушивать однополосные радиостанции.

Tecsun PL-660

The Tecsun PL-660 is currently one of the most popular portable shortwave radios on the market--and for good reason. The PL-660 has a full compliment of features and is quite easy to operate. The sync detector (selectable USB/LSB) is currently one of the best in the sub $150 US price range. Sensitivity and selectivity are both excellent. With the introduction of the Tecsun PL-880 on the market--a radio that may eventually replace the PL-660 as Tecsun's flagship portable--the PL-660 has also become more affordable and can be found at or near the $100 US price point with shipping. Here are a few of its specs:

  • AM/FM-stereo, Long Wave, Aircraft Band and Shortwave (1711-29999 KHz)
  • Single-sideband reception
  • Synchronous detection (USB/LSB selectable)
  • 2000 programmable memory presets
  • Full-featured clock, sleep timer
  • ATS Auto Tune Storage
  • AC Adapter, wire indoor antenna line and case all included

We recommend purchasing the Tecsun PL-660 from Universal Radio.

Grundig G3

Eton (or Grundig, same company) has been a leader in shortwave and self-powered radio technology for decades. The G3 has a smooth tuning wheel and direct keypad entry for finding frequencies. The G3 is very simple to operate compared to many similar receivers. This radio is very portable and has a rubberized body. For an $80 US radio, you'll be impressed with its sound quality and selectivity. Its ability to tune in FM stations is likewise quite impressive--and with built-in RDS, you'll have FM station and song information display and scroll on the G3's digital display. The only true negative about this radio is that it has weak sync detector lock. Still, without using the sync function, this is a very capable receiver--read our full review of the Grundig G3 for more details). Here are a few of its specs:

  • AM/FM-stereo, FM RDS, Aircraft Band and Shortwave (1711-29999 KHz)
  • 700 programmable memory presets
  • Full-featured world time zone: clock, sleep timer
  • Internally recharges Ni-MH batteries
  • AC Adapter, indoor antenna line and case all included
  • Single-sideband reception

Note that the Grundig has discontinued production of the G3 in 2013. There are still some on the market that are NIB (new in box), but I encourage you to purchase one from a retailer that will physically test the radio before shipping. Universal Radio will do this complimentary for their customers.

We recommend purchasing the Grundig G3 from Universal Radio.

Sony ICF-SW7600GR

Sony is also a leader in portable shortwave technology. Performance-wise, you'll find that this radio is on par with the Eton E5/Grundig G3 and is usually slightly more affordable. It gets consistently good reviews from users and guides. One of its outstanding features is its synchronous selectable sideband, a feature which helps to reduce fading distortion and adjacent-channel interference. This feature alone gives the Sony ICF-SW7600GR the ability to hold its own with radios in a higher price bracket. Another plus is that the Sony will allow you to select between upper and lower sidebands. This makes tuning in ham radio, utility and other SSB signals a breeze. The only thing lacking on this wonderful portable is a tuning knob, something I personally prefer for browsing shortwave bands. Here are a few of its specs:

  • AM/FM-stereo, medium wave and shortwave (150 to 29999 kHz)
  • MY-memory tuning memorizes and scans up to 100 frequencies
  • World clock and dual clock functions; built-in timer
  • Label presets with 6 alphanumeric letters
  • Single-sideband reception

We recommend purchasing the Sony ICF-SW7600GR from Universal Radio.

C. Crane CCRadio-SW

If you're not as concerned about portability, the C.Crane CCRadio-SW is an excellent value for performance. Think of the CCRadio-SW as a larger portable/table top radio (11.25" x 7.25" x 3.5"). What makes this radio stand out from its peers? Truly exceptional audio fidelity. The large built-in speaker has separate treble and bass controls and reminds me how important audio quality is while listening to a faint signal. This radio's audio will fill a large room. Shortwave sensitivity is very good. If you like to do Medium Wave (or AM broadcast band) Dxing, you're in for a treat. The CCRadio-SW has the best AM reception of any radio I've ever tested under $300. FM reception is equally amazing. Negatives? Well, besides being a larger portable--not ideal for stashing in your carry-on--the CCRadio-SW does not have direct keying to enter frequencies. Also, it does not have Single Sideband built in. However, it does have impressive array of external connections, including an IF Out connection, which (with an IF converter and some free software) will allow you to interpret SSB and an array of digital signals including DRM (Digital Radio Mondial). What really strikes me about the CCRadio-SW is its sheer ease of use--it's design is simple, ergonomic and effective. Here are some specs:

  • AM/FM/Shortwave [SW1, SW2, SW3 (1711 - 30,000 kHz)]
  • Controls include: RF Gain, Bandwidth, Bass and Treble, Fast and Slow Tuning
  • 50 Memories
  • Clock Radio with Snooze Alarm
  • External connections: Stereo Line Output (RCA type) and 1/8" Headphone Jack, IF Output for Input to Computer, External Antenna Connections.
  • Runs on four "D" size batteries or four backup "AA" batteries (not included)
  • Built-in charging circuit
  • AC Adapter and antenna connectors included.

We recommend purchasing the CCRadio-SW directly from C.Crane or from Universal Radio.

Check Amazon.com for pricing on the C Crane CCRadio-SW.

Eton E1

Unfortunately, the E1 is no longer manufactured by Eton, but they are still widely avaialble in the used market--check Universal Radio's used list or eBay (below). With that said, the Eton E1 is, by far, the best performer in the portable selection on this page. It offers a professional quality receiver that will impress the experienced shortwave listener and outperform pricier tabletop models. I really think of this rig as a tabletop shortwave radio that's designed to be portable. The only negatives I've heard about the E1 were some initial quality problems with the LCD display and the eventual "sticky" feeling of the rubberized body (click here for remedies). Here is a basic list of features:

  • Best possible features and receiver performance for the price
  • Wide FM, MW and SW frequency coverage
  • Rich audio quality
  • 1700 station presets
  • Large LCD display with dynamic soft touch buttons
  • Dual Conversion Superheterodyne Circuit - results in minimized interference through superior selectivity
  • Includes AC adaptor, manual and CD

Search eBay for an Eton E1.


Ultra-Portable Radios

If your budget is tight, or if you're looking for a radio that could easily slip into your glove compartment, backpack, or even jacket pocket, you need to look at an ultra-portable shortwave radio. Typically, there is a performance compromise with ultra-portable radios, in that: they usually don't have the ability to receive weaker signals like their more expensive cousins; they have a more limited frequency range; and they don't detect single-sideband signals. Still, the ones listed here are good performers for their size and price.

Tecsun PL-310

The Tecsun PL-310 has become a mini legend in the world of portable radio as it offers exceptional value and high-performance in a small package. What makes it so special? A DSP (Digital Signal Processing) chip that gives this ultra-portable excellent sensitivity and selectivity. A favorite amongst ultra-light Dxers, the PL-310 has exceptional overall performance on the shortwave, mediumwave and FM bands--especially for the price. The price? That's the other thing that makes this radio so special--about $60US including shipping. Mind you, the PL-310 is primarily available through eBay sellers in Hong Kong, so it may take up to 2 weeks to receive your new radio, but it's well worth the wait. Please see link below to search eBay for a Tecsun PL-310.

  • AM, FM, LW and Shortwave coverage
  • Digital Signal Processing (DSP)
  • 500 programmable memories
  • Multi-function digital display for frequency, signal strength, S/N ratio, clock & alarm, temperature (C or F) and battery consumption.
  • Tuning knob
  • Full specifications here...

Tecsun PL-380

The Tecsun PL-380 is my favorite radio under $60. Much like its cousin, the PL-310 (above), the PL-380 has a DSP (Digital Signal Processing) chip that gives this ultra-portable excellent sensitivity and selectivity. Indeed, the DSP bandwidth can be adjusted to 1, 2, 3, 4 and 6 kHz. The PL-380 is even marginally better at weak signal DXing than the PL-310. The PL-380 is my favorite radio for travelling--I even wrote a post about this on our blog. You can also click here to listen to an audio clip of it being compared to two lesser radios. Take note, however, that like the PL-310, the PL-380 does not have a single-side band mode.
In short, the Tecsun PL-380 is a superb value and excellent listening companion!

  • AM, FM, LW and Shortwave coverage
  • Digital Signal Processing (DSP)
  • 550 programmable memories
  • Multi-function digital display for frequency, signal strength, S/N ratio, clock & alarm, temperature (C or F) and battery consumption.

Kaito KA1103 or Degen DE1103

The Kaito KA1103 (and the KA1102, below) pack the most "bang for your buck" if you're looking for an inexpensive, ultra-portable entry into SWLing. The KA1103 is full featured and a great performer. I'm also impressed with the audio quality that comes out of this radio's relatively small speaker. One interesting design feature of the KA1103 is the large Digital/Analog frequency display. The LCD screen features the frequency display in digits (like all of the portables I recommend), but also sports a working digital representation of an analog frequency dial. As you tune up and down the band--with, yes, a tuning knob--the LCD needle moves along the display like an analog radio dial would. I suppose this could be a useful feature for people who like to see where they are on the band as they scan. I know of no other portable radio that has this quirky feature. The KA1103 gets a lot of good reviews for its ability to receive weak FM signals. My only gripes with the KA1103 and Kaito radios in general: 1.) I believe radio ergonomics could be better. 2.) You really need to read the manual before understanding all of the radio functions--I wish Kaito's were slightly more intuitive. 3.) Quality control varies with Kaito (more so than with Grundig/Etón and Sony)--make sure you buy from an authorized dealer and that you save your reciept. 
Still, for the money, with the KA1103 you're getting a receiver that is almost as good as the Sony and Eton E5 above. Features include:

  • AM/FM, long wave (100-519kHz), medium wave (520-1710 kHz) and shortwave (1711-29990 kHz)
  • 268 memory presets
  • Dual conversion technology, highly effective wide/narrow AM filter
  • Single-sideband reception
  • Tuning knob
  • Comes with 4 AA rechargeable batteries
  • AC adaptor can charge the batteries automatically

We recommend purchasing the Kaito KA1103 from Universal Radio.

Kaito KA1102 or Degen DE1102

What caught my attention before purchasing the Kaito KA1102 (a.k.a. Degen DE1102) were the numerous positive customer reviews on the internet. The KA1102 radio is small, but feature-packed. This radio actually has the ability to receive single-sideband (SSB)--one of the only radios in its price-class which can. Many shortwave radio listeners and radio amateurs consider the KA1102 to be an ideal backpacking rig because of SSB capability. Quality control with Kaito and Degen radios is hit-and-miss. I had to return my KA1102 twice before I got a fully functioning radio. If you live in North America, I strongly suggest you purchase the Kaito brand (not Degen) from an authorized dealer as it carries a warranty and can be returned/replaced. Degen products, in general, do not carry a warranty in N. America. Even minding some QC issues, I still believe the KA1102 is a solid performer and worth some minor hassel. Other features include:

  • AM/FM, medium wave (522-1710 kHz) and shortwave (3000-29990 kHz)
  • 190 memory presets
  • Dual conversion technology, wide/narrow AM filter
  • Single-sideband reception
  • Built-in alarm clock and sleep timer
  • Comes with 3 Ni-MH AA rechargeable batteries
  • AC adaptor can charge the batteries automatically

C. Crane CCRadio-SWP

I was skeptical when I first held the CCRadio-SWP in my hand. I mean, this is a tiny shortwave radio--how could it possibly perform? I was pleasantly surprised, however, once I turned it on. First of all--as with most C.Crane products--the layout and design are very simple, the display clear, with easily read icons and intuitive controls. The tuning knob on the right side is for fine tuning--no muting or chugging between frequencies, either. Shortwave and MW sensitivity are better than one might expect for a radio this size; I find myself comparing it to much pricier portables. Admittedly, this is a small radio, so lacks some qualities of larger portables: the small speaker has a tinny sound, the tuning knob is small, there is no single-sideband reception, nor does it have an external antenna jack. This is also one of the few radios I list that doesn't have a battery recharge feature. But (and this is a great "but") it also has the longest battery life of any radio I own: almost 70 hours on 2 AA cells! This is a great portable, and you're going to find that you take it with you everywhere. I certainly do. Here are some specs:

  • AM/FM/Shortwave [SW1, SW2 (2300 - 7500, 9200 - 22000 kHz)]
  • Controls include: RF Gain, Bandwidth, Bass and Treble, Fast and Slow Tuning
  • 200 Memories
  • Clock Radio with Snooze Alarm
  • Runs 70 hours on 2 "AA" size batteries (not included).
  • Optional AC Adapter available.

We recommend purchasing the CCRadio-SW directly from C.Crane or from Universal Radio.

Kaito KA1101

Like its bigger brother (the Kaito KA1102, above), this ultra-portable packs a lot of features and performance into a small package. It is quite sensitive on the shortwave bands, and, as a bonus, user reviews consistently tout this radio's ability to pick up weak FM stations. One odd thing about this radio is that it displays frequencies in MHz format rather than kHz. And being very compact, its speaker does not have the audio quality of the larger portable radios. But the larger radios don't fit so nicely in a car's glove compartment, either. Please note that the KA1101 does not receive single-sideband. Here's a list of its features:

  • AM/FM, medium wave (522-1710 kHz) and shortwave (3000-26100 kHz)
  • 50 memory presets
  • Dual conversion technology, wide/narrow AM filter
  • Built-in alarm clock and sleep timer
  • Comes with 3 Ni-MH AA rechargeable batteries
  • AC adaptor included

We recommend purchasing the Kaito KA1101 from Universal Radio.

Desktop Radios

Alinco DX-R8T

The Alinco DX-R8T is a fine receiver tabletop receiver and our recommendation as a first tabletop receiver. Why? It's simple to operate, yet it has all of the major features I like in a tabletop radio: it's well-built, easy to use, sensitive, versatile, and it has sufficient control options to help adjust adjacent interference and improve intelligibility. It also has a very attractive price at $499 US. It's next-best competitor is probably the Icom R75--but neither the Icom, nor the Palstar R30A, can be used as a Software Defined Radio and neither have the appropriate IF output for Digital Radio Mondial (DRM) as does the Alinco DX-R8T. In short, it's a lot of radio for the money, excellent for those starting in the hobby. With the Alinco DX-R8T, you get the best of both worlds, a simple "turn on and tune in" tabletop, plus a fully DRM ready SDR. Read our in-depth review of the Alinco DX-R8T by clicking here.
Here's a list of its features:

  • Frequency coverage: 150-30,000 kHz
  • 500 Hz CW Audio Filter
  • 600 Alpha Memories
  • 10 Hz Display
  • IF Shift
  • RIT
  • Squelch
  • Dual VFOs
  • Attenuator

Software Defined Radios

SDRplay RSP

The SDRplay RSP is one of the recent generation of economical wideband SDRs based upon innovative, inexpensive chipsets; in the RSP’s case, based upon the Mirics MSI3101 SDR chip, and a MSI001 tuner. Priced at a mere $149 US (plus shipping), the SDRplay RSP is one of the least expensive, yet full-featured SDRs which actually include the shortwave bands and below, and which require no extra upconverter. The SDRplay team continuously tweak and update the drivers which help the RSP interface with third party SDR applications. We believe the SDRplay RSP represents one of the best receiver values on this page; for $149 US, you will have a wide coverage receiver capable of rivaling radios in a much higher price category.

Of course, the SDR Play RSP is a software defined radio, so to unlock its potential, it must be paired with a capable PC, laptop or tablet device. At $150 it's a great way to get your feet wet in the world of SDRs.
