The XHDATA D-808 shortwave portable: A variation of the Digitech AR-1780?

Many thanks to SWLing Post contributor, Ivan, who shares the following:

In December, sales of this radio will begin. The seller promises to put the price of 60 US dollars. Radio of a level not lower than Tecsun PL-660 for such a small price is great! There is a video review on YouTube. Unfortunately in Russian. There is no more information on this radio on the Internet. I myself found out by accident.

Thank you for the tip, Ivan! I’m guessing this is yet another portable based on the Silicon Labs SL4735.

The display looks like that of the Digitech AR-1780 and the keypad configuration is nearly identical–the only visible difference being the shape of the SSB button which is rectangular on the AR01780.

The Digitech AR-1780 keypad.

The XHDATA D-808 Keypad.

The power buttons are also in different locations.

AliExpress has the D-808 in their catalog, but the price is listed at $2,000 per unit (!!!) with no shipping to the US. Perhaps the pricing formula changes if you place an order within Russia?

UPDATE: Ivan adds, “I talked to the seller of Xhdata D-808 on Ali about the crazy price claimed now. The seller replied that the price will be quite different and much more humane than what is now.”

Again, thanks for the tip, Ivan!

Post readers: If you have the XHDATA D-808, I’d certainly welcome a review. Please feel free to contact me about submitting one.

Tecsun PL-300 series modification: disabling soft mute

Many thanks to SWLing Post contributor, Troy Riedel, who shares the following tip. Troy writes:

While surfing the Net I found the following procedure that is said to “disable soft muting in Tecsun 300-series radios”.

I have a PL-390 and this has indeed seemed to work on it but I didn’t notice a difference with my PL-365.

Since I just found & tried this, I don’t know if this procedure must be repeated each time you use the radio? Maybe [Post readers] have heard of this before and/or have experience with it?

Here is the “reported” [supposed?] procedure that worked for the PL-390:

To disabling “Soft Mute” on Tecsun 300-series radios:

1. Select a shortwave frequency, preferably where there is no stations transmitting.
2. Tune down the frequency range with the dial, don’t tune up or it won’t work
3. Press the VF Scan button to let it automatically tune down
4. Tune down with the dial to stop the automatic scan. If the background noise is higher, then the “soft mute” / “dynamic squelch” has been disabled.

Thank you, Troy! I was unaware of this modification, but it seems easy enough to implement.

Post readers: Anyone have experience using this mod across the Tecsun 300-series receivers? Please comment!

Discounted New Tecsun PL-310ET Receivers on Amazon

Today I noticed that Amazon is offering an excellent price on the fine performing Tecsun PL-310ET portable AM-FM-SW radio.

The current sale price is $39.80 with free shipping for Amazon Prime members. This is a good price on a compact portable radio normally selling for $48.00.

Besides being a worthy value in a low cost portable, DSP-based radio for the SWL hobbyist, the PL-310ET also excels as a receiver to keep in your vehicle’s glovebox or your emergency kit.

The PL-310ET was included in Gary DeBock’s 2015 Ultralight Radio Shootout Review, and it fared quite well in Gary’s tests.

Jack Berg Sales: You too can own a brand new vintage radio!

Many thanks to SWLing Post contributor, Ron, who shares a link to Jack Berg Sales–a company specializing in New In Box (NIB) vintage electronics.

Ron points to one radio example in the Berg inventory, the Americana 10 Transistor AM Portable Pocket Radio:

 

The price is a very reasonable at $35.00 US plus $8.00 shipping and handling. Click here to view.

Jack Berg has dozens of other radios and electronics, though. It’s like walking through a vintage vault.

As Ron points out, Berg would probably make much more profit posting these vintage gems on eBay, but fortunately for us they do not.

It doesn’t appear Jack Berg does online ordering, which could make purchasing from outside the US quite complicated. In fact, they request a money order or cashier’s check sent to their office in El Paso, Texas.

(Side note: I honestly can’t think of the last time I purchased something from a company by sending in a money order or cashiers check.)

I suppose it would make sense to contact Jack Berg via email or phone (915-532-4519) to make sure your order can be fulfilled.

Additionally, there is no warranty of any sort.

These are NIB units and are untested. There’s a decent chance some radios may not function without replacing a capacitor or two and using a little DeOxit on switches and pots. For me, it’s worth the risk.

Post readers: please comment if you’ve ever purchased from Jack Berg.  How was your experience? See any particularly amazing models in the inventory? I bet many of the AM radios have decent ferrite bars inside!

Radio Day at Mount Mitchell State Park

Troy Riedel preparing the Tecsun S-8800 and Grundig Field BT for a comparison review.

Shortly after publishing my review of the Tecsun S-8800, SWLing Post contributor Troy Riedel contacted me and asked if I would consider comparing the S-8800 to the Grundig Field BT. Of course I was very curious how the $130 Grundig Field BT might compare with the $268 Tecsun S-8800, but I’ve got a lot on my plate at the moment and didn’t really want to purchase another large portable.

Long story short: Troy found a honey of a deal on a perfect Grundig Edition Field BT via eBay. He ordered it and we decided to bring the two radios together yesterday at beautiful Mount Mitchell State Park the highest point east of the Mississippi river.

Yesterday was an ideal day, too. The weather was picture-perfect, the park was (surprisingly) not too busy and propagation was the best I’ve experienced in weeks.

Troy left early in the morning and embarked on the 6+ hour pilgrimage to Mount Mitchell–I only live an hour away, so it was a casual drive for me. We met at noon.

Parks On The Air

After a quick lunch, we deployed my Elecraft KX2 with EFT Trail-Friendly antenna and made my first Parks On The Air (POTA) activation.

You might recall I was very active during the ARRL National Parks On The Air (NPOTA) program last year, but since then I’ve done few field deployments. It was great fun to get on the air again and do a park activation for the World Wide Flora & Fauna POTA program.

While we didn’t log a lot of stations, I was still impressed we worked stations from Texas to Quebec to the Azores. Not bad for 10 watts SSB!

Sure, I only worked a handful of stations, but this activation was essentially unannounced so chasers had no advance notice. No doubt, many more POTA activations are in my future! The bug has bitten!

Radio Fun

Except for a break to eat dinner at the park restaurant and a short hike to the peak of Mount Mitchell,  we played radio until about 8:00 PM. It was amazing, uninterrupted fun.

Troy spent a lot of time comparing the Tecsun S-8800 with the Grundig Field BT and made several videos. No doubt, he’ll post his thoughts and review in the near future!

Being a bit of radio geek, I couldn’t help but bring a few “extra” radios and accessories. Here’s what I packed:

We were a little disappointed to discover that both my Tecsun PL-680 and Grundig Satellit exhibited flaky behavior.

During my S-8800 comparison tests, a few weeks ago, I did notice that sometimes when I turned on the PL-680, it was absolutely deaf. Next time I turned it on, it worked fine. Yesterday, the PL-680 simply didn’t want to perform. I’m not sure what happened.

The Grundig Satellit, on the other hand, worked great, but sometimes if you touched either the antenna or even brought your hands near the radio body while tuned to a station, it would go deaf. You could correct this by tuning off frequency, then back on–still…very strange! It’s as if the AGC or RF gain were hanging up.

Have any Post readers experienced this before? I’ll look into the issue this week and reset both radios. Perhaps that will help.

A great “Mini DXpedition”

Thank you, Troy, for suggesting the meet up and for making the pilgrimage. It was great meeting you in person! I also thoroughly enjoyed watching someone else do comparison tests and exploring a new radio–Troy certainly has a knack for doing radio evaluations!

This has encouraged me to do more meet-ups, perhaps during my travels. Great fun!

Post Readers: be on the lookout for Troy’s comparison of the Grundig Field BT and Tecsun S-8800 in the coming days/weeks (no pressure, Troy!).

London Shortwave’s innovative PocketCHIP-powered field portable SDR

Many thanks to SWLing Post contributor, London Shortwave, who recently shared his latest SDR project: a field-portable, ultra-compact, SDR spectrum recording system based on the PocketCHIP computer.

London Shortwave has built this system from the ground up and notes that it works well but is currently limited to the FunCube Dongle Pro+ at 192 kHz bandwidth. There is no real-time monitoring of what’s being recorded, but it works efficiently and effectively–making spectrum captures from the field effortless. The following is a video London Shortwave shared via Twitter:

The PocketCHIP–the device his system is built around–is a $69 (US) handheld computer with color display:

I think this field portable SDR system is absolutely brilliant!

Homegrown innovation

London Shortwave has done all of the coding to make the FunCube Dongle Pro + work with the PocketChip computer. Even though live spectrum can’t be monitored in the field, the fact that it’s making such a clean spectrum recording is all that really matters.

All London Shortwave has to do is head to a park with his kit, deploy it, sit on a bench, read a good book, eat a sandwich, then pack it all up. Once home, he transfers the recording and enjoys tuning through relatively RFI-free radio.

A very clever way to escape the noise.

The kit is so incredibly portable, it would make DXing from any location a breeze. You could easily pack this in a carry-on item, backpack or briefcase, then take it to a park, a national forest, a lake, a remote beach–anywhere.

What I really love about this? He didn’t wait for something to be designed for him, he simply made it himself.

Thanks again, London Shortwave. We look forward to reading about your radio adventures with this cool field SDR!
