Hello Thomas,

As a regular reader of your blog, I was fascinated by the reports on the XHDATA D-220 [affiliate link] and ordered a black one. I was not disappointed. Of course it’s not a DXing machine, but finally we have a device wich reaches the reception quality of the old pocket radios again I used to carry around in my childhood. I still have a Philips D1220 from the 80s, which is even less sensitive than the XHDATA D-220.

This reminded me of my early radio days, when I would try to use the simplest methods to manipulate analog radios to do things that were not intended by the manufacturer. For example, by moving the band selector switch to an intermediate position, it was possible to get some radios to receive frequencies outside the intended range. Of course, I couldn’t resist and experimented with the D-220. It takes a bit of patience and sensitivity, but the radio really does hold some secrets.

Medium wave reception with the telescopic antenna

When I was listening to a weak station on medium wave and slowly moved the switch to short wave, the medium wave station got louder for a moment before the slide switch clicked into the correct position. In fact, the radio seems to switch to the telescopic antenna when you move the band selector a little toward short wave. A finger test on the antenna confirmed my suspicion. I also tried connecting a long wire, but that was counterproductive with all the men-made noise inside my house. Extended shortwave reception

A similar trick can be used to change the shortwave frequencies. If you slightly move the band selector from the shortwave position towards medium wave, the receiver switches to a different shortwave frequency range, covering between about 3000 and 7000 kHz. Now I was able to receive shortwave radio from Germany on 3975 kHz without any problems, and of course South Korea via England on 3955 kHz was no problem either.

I have not yet found out if the two FM bands can also be manipulated in this way, an intermediate position of the band selector seems to have no effect here. Perhaps one of the readers has discovered something?

Nutty Idea XHDATA D-220 DX Contest Results

In the run-up to the Nutty Idea XHDATA D-200 DX Contest, I really thought that sorting through the data might take a while. Why? Because I heard from so many people who said they had bought the D-220, were pleasantly surprised at its performance, and thought the contest sounded like fun.

But it turned out not to be so . . . only two “official” entries were received, plus an email from a ham radio friend who participated.

So I thought I would like the participants speak for themselves.

Don

First setup. I used a trimmed printer label and pen on my D-220 to mark the SW bands and key frequencies – so marks on WWV, CHU, FT8 on 7, 10, 14, 18 and 21MHz (nice I could hear them all) and some marks of the key SWL bands. I spent Friday trying to do everything indoors on my second floor and Sat outdoors. Of course, waiting for station IDs became the big roadblock. I didn’t get a lot of time over the weekend with events so I did what I could.

Identified Stations:

WWV 10 and 15 MHz (680 mi)
CHU 7.9 and 14.9 MHz (850mi)
WRMI on 17.5-18MHz (1410 mi)
WWCR on ~5.9 MHz (700 mi)
WGN Chicago – 720 kHz (350 mi)
KBGG Des Moines – 1700 kHz (240 mi)
KCNZ Cedar Falls – 1650 kHz (180 mi)
??Radio Exterior de Espana?? – I think so but couldn’t be sure 16m band

Friday evening – all times local CDT in midwest:

41m band – 3 stations – 2 in Spanish, 1 in english (no IDs)
49m band – two religious stations and one hispanic (that was 2-3 kHz above the 2 english stations – no IDs)

Saturday – started a more systematic approach.

really tried hard to hear WWV on 20MHz scanning down a bit from 21MHz FT8 – nothing
pretty sure I got Radio Exterior de Espana – but not sure
hear loud stations in the 31, 25, 22 and 16m bands but only a couple of IDs – noted above
heard a ton of MW stations but only picked out a few with IDs – noted above

Here are some key observations:

1. As a simple portable, the D-220 is a nice, very lightweight travel companion. FM and MW are sufficient for listening to games or music. I would definitely take it on a bike trip or camping or even to a game.
2. Headphone plug on the side??? Why?? Not good for a pocket or case. Should be on the top.
3. Outdoor use is moderate to excellent – performance improves dramatically. MW at night seems very good as does SW. This really is an outdoor portable with just the whip!
4. SW noise level is very good. Much better than Retekess or others.
5. SW overloading from MW is bad in the city yet just touching the whip with a finger removes it completely (changing impedance, grounding and antenna characteristics) allowing for clean SW.
6. FM audio sounds good but bass is severely attenuated. Hooking up the headphone jack to a stereo demonstrates how much low frequencies are cut whereas other cheap portables have great lows.
7. Audio tuning bandwidth drowns out stations close to each other if one is more powerful – fine tuning isn’t an option.
8. Tuning is general takes patience and a very sensitive touch to change the frequency.
9. SW is doable outdoors – need some testing with antenna mods – but the whip would give you some of the big SW guns.

All-in-all I was generally pleased with the radio at its price point and portability.

*****

William, KR8L

MWBC = 5, DX = 130 miles (WSM)
FMBC = 10 , DX = 50 miles (WCIL)
SW SFTS = 3, DX = 900 miles (WWV)
SWBC = 6, DX = 8000 miles (RNZ)
Amateur (CW) = 4, DX = 1010 miles (K1YAN)
Amateur (AM) = 2, DX = 1110 miles (W7YO)

Fun! Heard a lot more but no ID due to language and time constraints.

*****

Lou, KD2UHG (via email)

I could not spent as much time as I would have liked scanning the waves. I was picking up more SW then I imagined possible. Most noteworthy was the Music Through The Decades. From Akron Ohio, and Radio Romania. I heard all of the usual Christian preachers. Brother S was booming from Florida.After receiving the 220, I also bought the 219.

So, thank you Don, William and Lou for your participation and your comments.

I hope William’s observation sums it up for all of you: “Fun!”

A Band Aid for the XHDATA D-220

A Band Aid for the XHDATA D-220

By Bob Colegrove

In the olden days of analog radios, we would have generated a graph plotting frequency against a 0 to 100 linear bandspread scale. That permitted determination of a station’s frequency with varying degrees of accuracy.

The case of the charming little D-220 requires a simpler approach. The dial covers 5.6 MHz to 22 MHz in less than two inches. They could have cut off coverage at 18 MHz and gained a precious half inch of dial.

With the shortwave scale well below the pointer, I needed some additional guidance indicating where I was. Best not to get too fancy. I cut a strip off a sticky-back label and attached it to the dial right below the pointer. Using the left edge of the pointer as a guide, I marked off the location of each international broadcast band and a couple time stations. The width of each band isn’t much more than the point of a sharp No. 2 pencil. Any further resolution is hopeless, but at least you know what part of the spectrum you are in.

Red lettering is not part of the band aid.

Again, going by the old logarithmic analog dials you would expect the frequencies to be increasingly mashed together as you go higher. This is not the case with the D-220, nor do the increments appear to be very linear. At any rate, it is now relatively easy to tune from band to band.

The sensitivity and clarity of the D-220 is amazing. Perhaps it’s the green one.

Special Update to A Nutty Idea XHDATA D-220 DX Contest

30 Replies

Originally, the XHDATA D-220 DX Contest was intended to be on shortwave, but prompted by a question from Dennis, K2DCD, I consulted with Thomas (our Maximum Leader) and he said “I say with a radio this basic, simply go for anything and everything logged.”

That makes sense and sounds like pure, unadulterated DXing pleasure.

So here are the new rules:

You must use a D-220 with native (built-in) antenna (no hooking it up to your two-mile-long Beverage antenna)
No use of other radios or SDRs as “spotter” radios.
You must ID off the air.
Any band the D-220 receives.
Any location.
Contest starts 6 pm your local time on Friday, August 16, 2024 and it ends at 6 pm your local time on Sunday, August 18, 2024.
Log the time, the estimated frequency, the station ID and what you heard.

There are no prizes, just bragging rights.

Feel free to report in lavish detail on your experience during the contest . . . especially if you had fun!

A Nutty Idea

Official Disclaimer: “Yes, XHDATA is a supporter of the SWLing Post but this is my own crazy idea, and we aren’t getting any commissions from the sales. XHDATA doesn’t even know we’re doing it!”

It’s all Robert Gulley’s fault. He had the temerity to post an article about the XHDATA D-220 entitled “A Throwback to a Simpler Time” — I read it, was intrigued, and ordered one.

It arrived today, and, by golly, it actually works. I snapped a couple of AA cells into the battery compartment and discovered immediately that it appears to have a pretty hot FM receiver section. Then I tried medium wave and pulled up several of the local AMers. Then, the acid test: shortwave. Robert Gulley was right: “you will want to turn the dial slowly, very slowly.” But, sonuvagun, if you use a safecracker’s touch, you will actually discover and receive distant shortwave stations on that dinky telescoping whip antenna . . . with an exceedingly inexpensive radio.

So here’s my Nutty Idea: How about an XHDATA D-220 DX contest?

Rules:

You must use a D-220 with native antenna
No use of other radios or SDRs as “spotter” radios.
You must ID off the air.

As Thomas, our Maximum Leader, put it: “It’s so insanely cheap, it’s a great way to have everyone on a level playing field. Well, unless someone gets the yellow version which we all know has special powers.” (Yes, I bought the yellow version.)

Further, I proposed we kick this thing off at 6 pm your local time on Friday, August 16, 2024 and it ends at 6 pm your local time on Sunday, August 18, 2024. You log the time, the estimated frequency, the station ID and what you heard. There are no prizes, just bragging rights. The object: to have fun!

So, whaddya think?

Or should I go back to the home and start taking my meds?
