Phil’s review of the Digitech AR1946

digitech-AR1946-frontMany thanks to SWLing Post reader, Phil Ireland, who shares his review of the Digitech AR1946:

I’ve now purchased the AR1946 and I have to say, I’m very impressed! No noise problems at all with mine, although if you listen very carefully under certain conditions, you can discern a slight digital hash. Not in anyway imposing though.

This radio is super sensitive, AM comes very close to the CCRadio-EP in performance and FM is outstanding. SW is very impressive but there are a few quirks in tuning:

  • below 10MHz, you hit the Frequency button, key in the value and hit the Frequency button again to tune [to the desired station]
  • above 10MHz, you hit the Frequency button, type in the value and it jumps straight to the frequency [without pressing the Frequency button again].

Not a great issue but worth knowing.

This radio has 7 bandwidths in AM both accessible on MW and SW and rudimentary fine tuning with a separate wheel control. Unfortunately FM only has 1 bandwidth but seems well chosen. DAB+ is not available in Regional NSW so that cannot be commented on.

The telescopic antenna is ridiculously small but seems to pull in the signals with no problems. There are external antenna connections for improved performance.
Audio is very pleasant and you can control both treble and bass with the push of a button. The display is bright, well lit and easy to read with a useful tuning indicator.
There are a number of useful features and with 700 memories, there are more that needed. The radio is very reminiscent of the Grundig Satellit 700 in some respects. Build quality seems very good, time will tell if reliability becomes an issue.

What I don’t like is the radio partially mutes when tuning, this is annoying when bandscanning with the rotary tuning control. I have noticed what appears to be synchronous detection being used as occasionally when tuning onto a frequency, you will hear the detector lock on frequency. If so, there is no control over this feature. That may explain the display showing synch but the final model has automatic synch lock..

The AR1946 dispenses with Airband that was good on the AR1945 and SSB. Its a pity that SSB is omitted but along with the Tecsun PL310ET with DSP, they don’t have SSB capabilities as well. I suspect the same DSP chip is being used in this radio.

Can I recommend the radio? A resounding yes! As mentioned I’m very impressed. Try before you buy, though, as it may be that QC is variable along with many Chinese radios of late.

Digitech-AR1946-Front-HandleMany thanks for your review, Phil!

When Phil notes a lack of noise in his receiver–he’s referring to a previous review we posted from Avo, who complained of internally-generated noise in his AR1946.

It seems, like with many other DSP portables (including the Sangean ATS-405) internally-generated noise may vary from unit to unit. I’m guessing this could have to do with slight variations in the board assembly (variations in soldering, grounding, shielding connections).

As Phil advises, please check your radio immediately after purchase and compare it to another shortwave portable if you have one available. This way, if you detect a noisy receiver, you can get a refund or exchange within the time limits of the return policy.

The Eco USBcell: a LiPo AA USB rechargeable cell

EcoUSBCell

Many thanks to SWLing Post reader, Steven Crawford, who writes:

Avid follower of your SWL Blog and site. I saw these and thought your followers may find these AA and AAA lithium ion USB rechargeable cells may be of interest as they are limited to 1.5 volts. I’m interested for my C. Crane Pocket SW and Sony ICF-SW7600GR as well as for various Mag Instrument flashlights.

An excerpt from PCWorld:

Card-carrying members of the Radio Shack Battery of the Month Club, get ready to salivate: The Eco USBcell is the most exciting development we’ve seen in rechargeable batteries in a long time.

Unlike most rechargeable AA and AAA cells that use nickel metal hydride chemistry, the USBcell’s are based on the same advanced lithium polymer technology that’s used in many smartphones.

That may not sound like a big deal, but one limiting factor in using LiPo in a AA or AAA battery is voltage. LiPo and Lithium Ion’s typical minimum voltage is 3.7 volts and would fry a standard device looking for 1.5 volts.

The Eco USBcell features a power control chip to match the voltage to the standard disposable alkalines we’re used to.

[…]And that’s not even the slick part of the USBcell. Once the battery is dead, you simply pull the top off to reveal a standard USB Type A port. That means there’s no need to carry a charger anymore. Plug it into a 1 amp wall-wart charger and it’ll be topped off in about two hours, even flashing an embedded green LED to let you know. The company says it can technically be charged on a computer’s USB port, but it’ll be a lot slower.

ECOusb-aaThanks, Steven! This is a very cool product, indeed! I noticed that, on BestBuy, there are currently six reviews–dating back to October ’15–with a full 5 star rating. Not bad.

With USB ports and chargers being ubiquitous in our world, I can see where charging these would be very convenient.

My only hesitation is that I have a healthy fear of LiPo batteries after having a GoalZero LiPo pack melt down and burn on my bed while charging once. That was three years ago, however, and charging circuits have become much more reliable since then.

I’ll put these on my wish list and purchase them later in the year if the reviews remain positive. I just purchased a 12 pack of Panasonic Enloop cells, so I’m in no hurry.

Thanks again for the tip, Steven!

The Kaito KA108: a shortwave portable with built-in record function

Kaito-KA108

Many thanks to SWLing Post reader, Ante, who writes:

Looks like Kaito has a new radio in the works. Portable shortwave receiver with record function. It looks very much like some of the Eton portables.

Here’s Universal Radio’s description:

The Kaito KA108 is a great AM, FM shortwave receiver with a very special feature. It has a record function that allows you to record off the air automatically! It can save the audio to a Micro SD Card or USB Thumb Drive (not included) inserted via the top panel. It also features a large backlit display with battery indicator, signal meter and conventional alarm function with two programmable wake up times.

 

There is a Line Input Jack and stereo earphone output jack. Power input is via a USB port. The KA108 comes with: Li-ion battery and USB charging cable. One year limited mfg. warranty.

Thank you for the tip, Ante! Universal has pricing and availability listed as TBA at time of posting.

I noticed that Amazon has the same radio via Kaito for $67.20 (shipped). Interestingly, the Amazon description reads:

“Kaito KA108 Super Sound quality AM FM Shortwave Radio with MP3 Player and Radio Recorder, Radio Time Schedule Recorder,Alarm Clock+ More”

I hope the “Super Sound” part means that the internal speaker is like that of the Melson S8, with an acoustic chamber. Those speakers have amazing fidelity for such a compact size. Checking this morning, the Amazon listing only has one review–a 5 star–but it wasn’t a verified purchase, had few details on performance and, frankly, smacked of shill a little too much for my taste.

I certainly hope this isn’t simply a Melson S8 with a re-designed body. As I mention in this review, the S8 suffered from terrible internal noise, rendering it useless on shortwave.

Kaito-Ka108-side

The Line In, Phone and DC IN 5V jacks are in the same placement and order as the S8–but the S8 also has the power button and MicroSD card on the side panel, the KA108 has the MicroSD card slot on top, along with a USB thumb drive slot.

Kaito-KA108-Top

I have hope that this is not a re-badged Meson S8 because the KA108 has features the Melson S8 did not, including the ability to record and even schedule recordings!

There are so few portables on the market that can record on the shortwave bands. There are no portables currently on the market that have a sensitive/selective receiver and do a good job of recording.  Even if the KA108’s receiver is only average, if it has a clean recording function, it will be a keeper for me.

My fingers are crossed!

Of course, I will certainly review the Kaito KA108 here on the SWLing Post.  I will most likely wait until Universal Radio has the units in stock, which I imagine will be soon.

A high-gain ferrite bar antenna for the PL-360/PL-365 and CountyComm GP5 series

Ferrite-Bar-Antenna-PL-365-GP5SSB

If you own a Tecsun PL-360, PL-365 or a CountyComm GP5/DSP or GP5/SSB, you might take note of this large ferrite bar antenna offered by a Greece-based seller on eBay.

Ferrite-Bar-PL-365

As you can see in the image above, this antenna is substantially larger than the stock MW antenna supplied by the manufacturer. According to the seller, this ferrite bar antenna has a 10 – 25 db gain over the stock external antenna. I imagine its ability to null unwanted signals is also much better.

The price is about $40 US shipped internationally.

Have any SWLing Post readers ordered this antenna? If so, please share your comments/reviews.

Sangean DT-500W: a new AM / FM / Weather Alert Pocket Radio

Sangean-DT-500W-Front

Many thanks to my pal, Jeff McMahon from The Herculodge, who has just apprised me of a new Sangean AM/FM/WX portable: the DT-500W. Jeff learned about the new pocket radio via a comment on his blog.

DT-500W-SideIt appears the DT-500W is powered by a rechargeable Li-ion Polymer 3.7V (1850mAh) battery. I would expect good longevity from a full charge.

Based on the specifications, the receiver covers all NOAA weather radio frequencies, the FM broadcast band (87.5 – 108 MHz) and the full AM broadcast band (520 – 1710 kHz). I also noted on the spec sheet, however, that the AM broadcast (mediumwave) band is limited to 10 kHz tuning steps. Not a great contender for the ultralight DXer or someone who travels outside North America if so!

Click here to view the Sangean DT-500W on Sangean’s website.

As of posting, I can’t find the DT-500W listed with any online retailers.

Thanks again for the tip, Jeff!

The Amateur Astronomer: Tune in to Troy’s Christmas gift

imageSWLing Post reader, Troy Riedel, received a gift like no other from his son this Christmas. No, it wasn’t the fabulous Celestron telescope in the above photo.  On Christmas Eve (December 24) Troy sent the following message:

Merry Christmas, Thomas.

I have to tell you what my son gave me for Christmas a few hours ago.

He purchased 1-hour of radio time for me on WBCQ (5110) for Wednesday, 30 December at 8 P.M. EST.

I will have to pre-record approximately 50-55 minutes over the coming days (not much time to prepare).

After telling my son this is cool – I also added this is the most stressful gift I’ve ever received.

My son suggested I may want to talk about astronomy.

A cool gift, indeed.  Evidently––and even more cool–– Troy is something of a hardcore amateur astronomer. I also encouraged him to do a show on this topic; I can’t think of the last time I heard a show about astronomy on shortwave!

Troy Riedel, host of The Amateur Astronomer

So, despite the challenge of putting a show together in less than a week, Troy confirmed yesterday that he has already completed the show and WBCQ will air it at the following time/frequency:

5,110 kHz on Dec 30, 2015 at 8:00 PM EST (1:00 UTC December 31, 2015)

Troy is looking forward to reception reports and will announce the address during the broadcast.

Oh––and being the good man he is, Troy is also including a PSA for Ears To Our World. Thanks, Troy!

Looking forward to the show!

WRTH 2016: I’m glad I stopped by the post office

WRTH-2016

I just brought home my copy of WRTH 2016 from the post office. I didn’t expect it to arrive so soon from the UK, so I’m very much looking forward to reading through it over the next few days. It’s a special volume, too: WRTH’s 70th anniversary edition!

I’m also honored to have a feature article and two reviews in this particular edition.

You can order your copy from Amazon or Universal Radio here in the US, from Radio HF in Canada. Otherwise, consider ordering directly from WRTH online.

I’ll post an overview of WRTH 2016 in the coming days.
