Best MW DX Receiver: Raddy MLite-880 Leads

The best MW DX receiver in this set is the Raddy MLite-880, an SDR portable with a 2.3-inch spectrum and waterfall display, SSB demodulation, and a 5000mAh 21700 battery. If you want the same medium-wave chops in a touchscreen body a household can share, the Raddy DP-666 with its NXP TEF6686 chip and 2.8-inch color panel is the better buy.

How the six were screened

Six listings survived the cut, and two of them are not receivers at all. Both the Kircuit and saschedross entries are 6V AC adapters intended for the RadioShack DX-398, a discontinued FM/MW/LW/SW portable. Amazon's search returned them under the medium-wave DX query because the DX-398 name lives in the product titles, not because they receive anything. I have kept them in the ranking, because a working DX-398 without power supplies it, but the real receivers to buy are the top four.

Here is what I looked for in the four actual radios:

• Explicit medium-wave coverage in the tuning range, not just FM and shortwave.
• SSB, CW or synchronous AM demodulation, since narrow modes help pull weak MW carriers out of the noise.
• Adjustable bandwidth or DSP filtering, listed by the manufacturer.
• A real antenna solution: telescopic, external jack, or a loop.
• A published battery figure, because MW DX happens at night and often away from mains.

Three of the four cleared every bar. The fourth, the pocket TEF6686 unit, clears most of them at a smaller size.

Best MW DX receiver at a glance

What actually decides an MW DX receiver?

Most guides compare medium-wave portables by band coverage. Every real receiver in this set covers MW, so coverage decides nothing. The real deciding criterion is what happens when the signal is weak.

Two things matter after dark. The first is narrow demodulation modes. SSB (both LSB and USB), CW and synchronous AM let you strip away one sideband of interference and lock onto a carrier that plain AM will lose. The second is filtering: adjustable bandwidth and DSP noise reduction, so you can trade audio quality for readability on a fading signal.

The four real receivers here split cleanly on this test. The MLite-880 lists SSB (LSB/USB), CW, SAM, NFM, WFM and AM demodulation with adjustable noise reduction, notch filtering, and AGC. That is the deepest toolset in the set. The DP-666 and both TEF6686-based radios lean on the NXP chip's DSP filtering and adjustable bandwidth, which is strong on medium wave, but only the dual-chip generic unit adds explicit LSB/USB/CW through its SI4732 hardware.

A spectrum display is not decoration. It shows you where the activity is before you tune to it, and on a crowded MW band that is the difference between an hour of scanning and five minutes.

1. Raddy MLite-880 SDR Shortwave Radio Receiver — Best overall

The MLite-880 is the only radio here that pairs a real-time spectrum with a full menu of narrow modes, which is the combination MW DX actually needs.

Best for: chasing weak medium-wave stations after dark with a spectrum view Skip it if: you only want casual FM listening on the porch

Raddy positions the MLite-880 as a full-band SDR receiver, and the specification list backs the label. Raddy says the 2.3-inch display carries a real-time spectrum and waterfall so you can see signal activity while tuning or scanning. The demodulation menu, as listed, covers SSB (LSB/USB), AM, CW, SAM, NFM and WFM, with flexible tuning steps. That is the fullest mode list in the set, and SAM in particular helps on fading medium-wave carriers.

DSP support is written in explicitly: adjustable noise reduction, notch filtering, and AGC. Direct frequency entry through the keypad plus fine-tuning with adjustable steps is the pattern serious listeners want. Power comes from a 21700 lithium cell rated at 5000mAh, replaceable, with USB-C charging. Dimensions are 7.9 x 3.9 x 2 in, which is a coat-pocket radio, not a shirt pocket one. Raddy lists an 18-month warranty. It is the most expensive pick here, and it is also the one buyers reach for more often than the DP-666 within this set.

Pros:

• 2.3-inch real-time spectrum and waterfall display
• SSB, CW, SAM, NFM, WFM and AM demodulation listed
• Adjustable DSP noise reduction and notch filter claim
• 5000mAh replaceable 21700 battery with USB-C
• 18-month warranty stated

Cons:

• Highest price position of the six
• No touchscreen, unlike the DP-666
• Larger body than the pocket TEF6686 rig

2. Raddy DP-666 Full Band DSP Radio — Best for families

The DP-666 turns a serious TEF6686 receiver into something anyone in the house can drive, thanks to a 2.8-inch color touchscreen and stylus.

Best for: a shared shack radio with a touchscreen anyone can drive Skip it if: you insist on a real-time waterfall for band scanning

The DP-666 is built around the NXP TEF6686 chip, which Raddy pairs with DSP filtering and an RDS decoder across AM, FM, LW, MW and SW. On medium wave that means adjustable bandwidth and interference control, the two features that separate a DX receiver from a table radio. Raddy also lists real-time signal metrics, including signal strength in dBμV and carrier-to-noise ratio, which is unusual at this price position.

The 2.8-inch color touchscreen with stylus is the friendly bit. Direct-entry frequency input through the numeric keypad is still available, so nothing is hidden behind touch alone. Raddy calls out firmware upgradability based on the PE5PVB open-source project, which is a real perk if you like tinkering, and a telescopic plus donut (loop) antenna combination that helps on MW specifically. Battery is again 5000mAh. The trade-off against the MLite-880 is the absence of a spectrum waterfall and no SSB in the listed mode set, which is why it lands second for hardcore DX and first for shared use.

Pros:

• NXP TEF6686 chip with DSP filtering
• 2.8-inch color touchscreen plus stylus
• Numeric keypad for direct frequency entry
• Donut (loop) antenna aids medium-wave reception
• Firmware upgradable via PE5PVB project

Cons:

• No real-time spectrum or waterfall display
• SSB not listed in Raddy's mode summary
• Warranty limited to 18 months

3. Dual Chip FM AM SSB Airband Receiver — Most versatile

A dual-chip design puts a TEF6686 and an SI4732 in the same box, so you can pick the better front end for whatever you are chasing.

Best for: hobbyists who want both TEF6686 and SI4732 in one box Skip it if: you dislike generic-branded gear with thin documentation

This is the unusual one. The listing says the radio carries both a TEF6686 and an SI4732 as independent hardware paths. In practice that means the TEF6686 handles FM/LW/MW/SW with DSP noise reduction and full RDS data, while the SI4732 offers AM/FM/LSB/USB/CW and AIR band with hardware decoding. For medium wave that split is genuinely useful: the TEF6686 tends to shine on strong broadcasters, and the SI4732 gives you SSB when a weaker signal needs it.

Physically, it is small and light: 0.94 x 5 x 2.4 in and 0.66 lb. The listing calls out a 40mm long-stroke full-range speaker and an 820mm rod antenna, which is longer than what pocket radios usually ship with, and Bluetooth for audio out. Warranty is stated as 1 year, the longest published warranty here after the two Raddy units.

The trade-off is polish. This is a generic-branded product with a model string that reads like a database key, so documentation and firmware support are what you make of them. It is also the second-most-expensive pick in the set.

Pros:

• Dual TEF6686 and SI4732 hardware paths
• SSB, CW and AIR band via SI4732
• 820mm telescopic rod antenna
• 40mm full-range speaker for audio
• 1-year warranty stated

Cons:

• Generic brand and minimal product identity
• Second-highest price position in the set
• Bluetooth adds cost some MW listeners will not use

4. TEF6686 All Band Touch Screen Portable Receiver — Best upgrade

A 3.53 oz pocket radio with a 2.4-inch IPS touchscreen and the same TEF6686 chip the bigger sets use.

Best for: a coat-pocket DX rig you can carry on trips Skip it if: you need long battery life away from a USB port

This is the smallest real receiver here. Dimensions are 1.97 x 3.23 x 0.79 in and weight is 3.53 oz, small enough to disappear in a jacket. Under the case, the listing names the TEF6686 chip that drives full-band reception across FM, LW, MW and SW, with RDS decoding for station name, program text and time. The interface is a 2.4-inch IPS resistive touchscreen with switchable UI themes, which is a nice touch when your usual seat is dim.

For MW specifically, the strength is the TEF6686 sensitivity claim and the DSP-based interference control. The listing also mentions two audio outputs: a 3W speaker amplifier and a Hi-Fi headphone amplifier through a 3.5mm jack, and headphones matter for late-night listening. What you give up is any published battery capacity, no explicit warranty beyond "technical support", and the small internal antenna that comes with a body this size. On a strong regional MW station it is more than enough. On a rare distant catch, an external wire will help.

Pros:

• TEF6686 chip in a 3.53 oz body
• 2.4-inch IPS touchscreen with theme options
• 3W speaker plus Hi-Fi headphone output
• Full RDS decoding across supported bands
• Dimensions of 1.97 x 3.23 x 0.79 in

Cons:

• No published battery capacity
• Warranty listed only as "technical support"
• Small internal antenna limits weak-signal MW

5. saschedross AC Adapter for RadioShack DX-398 — Best budget pick

Not a receiver. This is a replacement 6VDC 300mA power supply for the RadioShack DX-398 medium-wave portable.

Best for: reviving a DX-398 that lost its wall wart Skip it if: you do not already own a compatible RadioShack receiver

The DX-398 was a well-regarded FM-Stereo/MW/LW/SW portable, and one of the reasons people keep buying adapters like this is that the radio itself is still respected as an MW DX rig. If your DX-398 is still on the shelf, a working 6V 300mA supply keeps it powered when the internal cells are tired. saschedross lists this adapter with the correct 6VDC 0.3A output specifically referenced to the DX-398 catalog number (20-228 / 20228).

Beyond the voltage and current rating, the specification list is thin. Colour is stated as black, connectivity is powerline (as it should be for a wall adapter), and the physical dimensions are not published. It is the cheapest of the six, and only one seller lists it. Treat it as an accessory, not a receiver. If you do not have a DX-398, buy the MLite-880 or the DP-666 instead.

Pros:

• Direct DX-398 replacement, 6VDC 300mA
• Cheapest of the six
• Slim wall-plug form factor
• Simple two-pin mains input

Cons:

• Not a receiver, just a power supply
• No published physical dimensions
• Only useful if you own a DX-398
• No stated warranty period

6. Kircuit 6V AC/DC Adapter for DX-398 — Best minimal setup

Also not a receiver. Kircuit sells the same class of 6V 300mA adapter, and it accepts 100-240V input, so it travels.

Best for: a travel-ready spare adapter for an older RadioShack DX-398 Skip it if: you want a full receiver, not a power supply

If you already own a DX-398 and travel with it, the Kircuit version has one useful attribute the saschedross unit does not advertise: a 100-240V AC input range. That means it works on foreign mains with just a physical plug adapter, no separate voltage converter. Kircuit lists over-charge protection and a dynamic charger IC, which is standard talk for this class of product.

The specification block is otherwise minimal. There is no stated weight, no stated warranty, no stated dimensions, and the receiver it powers is discontinued. This lands sixth for the same reason the saschedross adapter lands fifth: it is not a receiver, and a "best MW DX receiver" ranking is really a receiver ranking with two accessories that Amazon returned along the way. Kircuit sits at the second price position of the six. Buy it only if the DX-398 is already yours.

Pros:

• Universal 100-240V AC input for travel
• Correct 6VDC 0.3A rating for DX-398
• Over-charge protection claimed
• Compact wall-plug form

Cons:

• Not a receiver
• No published weight or dimensions
• No stated warranty period
• Requires you to already own a DX-398

TEF6686 or SDR: which chipset wins on medium wave?

Three of the four real receivers in this set use the NXP TEF6686. The MLite-880 goes a different route with a general-purpose SDR front end. Both approaches can pull good medium-wave signals, and the differences matter.

TEF6686 strengths:

• Mature DSP behaviour on AM and MW, with adjustable bandwidth in fine steps.
• Full RDS decoding on FM, which the SDR portables also handle.
• Well-understood firmware ecosystem, including the open-source PE5PVB project the DP-666 references.

SDR strengths, as the MLite-880 shows them:

• A visual spectrum and waterfall makes band conditions readable at a glance.
• Broader demodulation menu in a single unit, including SAM and CW.
• More granular tuning steps and noise-reduction controls in one interface.

For pure medium-wave chasing after dark, the SDR spectrum is the tie-breaker in this set, which is why the MLite-880 wins overall. For someone who mainly listens to strong regional stations and only occasionally reaches for a distant catch, a TEF6686 unit like the DP-666 or the small pocket radio is plenty.

How much does the antenna matter?

More than the chipset, honestly. Medium-wave signals want length or a loop, and no built-in whip is really long enough. Two things in this set stand out.

1. The DP-666 lists both a telescopic and a donut (loop) antenna. That loop is the piece that helps on MW, because loops have directional nulls you can rotate away from a local interferer.
2. The dual-chip generic radio lists an 820mm telescopic rod, which is longer than most portables ship with, and useful across MW and SW alike.

The MLite-880 does not call out an unusual antenna in its feature list, but its rear panel accepts external inputs typical of SDR portables, so an external MW loop or long wire is straightforward. The pocket TEF6686 receiver is the most antenna-limited of the four, because its 3.53 oz body cannot fit a long rod. A cheap external wire clipped to its telescopic will lift MW performance noticeably.

The two RadioShack adapters have no antenna at all. That is the point. They exist to power a DX-398 whose internal ferrite loop does the medium-wave work.

What the listings do not tell you

Amazon listings for radio hardware skip several things a DX listener cares about:

• Actual sensitivity in μV/m. None of the four real receivers here publishes a figure. The TEF6686 chip has a datasheet, but the housing, antenna and shielding change the outcome.
• Firmware version at shipping. Both Raddy units are firmware-upgradable, and the DP-666 references the PE5PVB project by name. Which build ships is not stated.
• Case shielding quality. DSP portables can pick up their own display noise on MW. This is the single most annoying flaw on cheap TEF6686 radios and no listing will admit to it.
• Real battery life in hours. Three radios list 5000mAh cells, but hours of MW listening depend on volume, backlight and mode.
• Included accessories beyond antennas. Cables, carry pouches, and external MW loops are usually left out.

Treat feature bullets as marketing. Treat published specifications, in the units the manufacturer gives, as your evidence base. That is what I have done through this ranking, and it is why the MLite-880 rises: it is the one product whose specifications explicitly cover the modes and controls MW DX needs.

Which upgrades are worth paying for?

The best mw dx receiver decision is really a decision about what tier you want. Here is how the money maps across this set, without prices, because prices move.

• Entry position. In this set, the entry tier is occupied by the two DX-398 adapters. They only make sense if you already own the receiver they power. There is no entry-tier standalone MW DX radio here.
• Mid position. The DP-666 and the pocket TEF6686 sit here. What you get for the step up from entry is a real receiver: TEF6686 chip, full MW coverage, DSP filtering, RDS decoding, and a touchscreen or IPS display.
• Premium position. The dual-chip generic and the MLite-880 land here. What extra money buys is either dual-chip flexibility (TEF6686 plus SI4732 with SSB) or SDR features (spectrum, waterfall, SAM, CW, notch filter). Both are meaningful jumps over the mid tier.

The one upgrade I would push people toward, if the budget stretches, is the spectrum display. It changes how you scan the band. Everything else is refinement.

The verdict

If you are shopping the best mw dx receiver in this set for serious weak-signal work, the answer is the Raddy MLite-880. It is the only pick that pairs a real-time spectrum and waterfall with SSB, CW, SAM, adjustable noise reduction and a notch filter, and it runs on a replaceable 5000mAh 21700 cell with USB-C charging. Raddy stands behind it for 18 months.

If your medium-wave listening is more casual, or the radio has to be usable by anyone in the household, the Raddy DP-666 is the better buy. The 2.8-inch touchscreen and stylus lower the learning curve without hiding the numeric keypad, and the TEF6686 chip with the donut loop antenna handles MW competently. The cutoff between them is straightforward: if you want to see the band, buy the MLite-880; if you want to hear the band with less fuss, buy the DP-666.

The dual-chip generic radio is the interesting outlier for hobbyists who value TEF6686 and SI4732 side by side. The pocket TEF6686 is a travel companion, not a primary rig. The two adapters serve owners of a specific older RadioShack receiver.

FAQ

Is the Raddy MLite-880 worth it for medium-wave listening?

Is the Raddy MLite-880 worth it depends on how weak the signals you chase actually are. For serious MW DX after dark, yes, because it lists SSB, CW, SAM demodulation, adjustable DSP noise reduction, a notch filter and a real-time spectrum with waterfall. For daytime listening to strong regional stations, a mid-tier TEF6686 radio like the DP-666 gives you most of what you need.

What is the best mw dx receiver for beginners?

The best mw dx receiver for a beginner in this set is the Raddy DP-666. The 2.8-inch color touchscreen, stylus, and numeric keypad let you tune by touch or by direct frequency entry, and the TEF6686 chip handles the DSP work in the background. It also ships with a donut loop antenna, which is the piece that most helps a new listener pull medium-wave stations cleanly.

How does the MLite-880 compare to the DP-666?

How does the MLite-880 compare to the DP-666 comes down to interface and modes. The MLite-880 is an SDR portable with a 2.3-inch spectrum and waterfall display, SSB, CW and SAM, and no touchscreen. The DP-666 is a TEF6686 receiver with a 2.8-inch color touchscreen and stylus, but no waterfall and no SSB listed. Both use a 5000mAh battery and carry an 18-month warranty.

Do I need SSB to do medium-wave DX?

Do I need SSB is a fair question, and the honest answer is: not always, but often. Plain AM with a narrow filter handles many MW catches. SSB (LSB or USB), CW and synchronous AM come into their own on fading signals or when a strong adjacent station bleeds across. In this set, the MLite-880 and the dual-chip generic radio give you those modes; the DP-666 does not list SSB.

Are the RadioShack DX-398 adapters actual receivers?

Are the RadioShack DX-398 adapters receivers? No, they are not. Both the Kircuit and saschedross entries are 6VDC 300mA wall adapters designed to power the discontinued RadioShack DX-398 FM/MW/LW/SW portable. They appear in medium-wave DX searches because the DX-398 name sits in their titles. Buy one only if you already own a DX-398. Otherwise, choose the MLite-880 or the DP-666.

If you are new to medium-wave DX, start with the DP-666 and a length of hookup wire clipped to the telescopic. You will hear more distant stations in your first week than most listeners hear in a month with a table radio, and the touchscreen keeps the learning curve gentle. When you outgrow it, and you eventually will, step up to the MLite-880 for the spectrum view. That order costs less than buying the spectrum radio first, discovering you are not sure how to drive it, and shelving both. Medium wave rewards patience and a decent antenna above all else.
