Gentle reminder: The Great Medium Wave Daylight DX Challenge is tomorrow!

Here are the rules:

Frequency range is the medium wave band: 520-1710 kHz
10 am to 2 pm your local time on Saturday, March 11, 2023 .
Any radio with any antenna, but must be the radio at your location (no using remote internet radios)
The listener must hear the signal in real time
The stations must be ID’ed by listening to the signal.
Your report should include:
- Your name (or Internet handle)
- Your receiver and antenna (stay with the same setup from beginning to end; if you use multiple setups, provide a separate report for each).
- Your location
- The time, the frequency, and the ID of each station heard
- The total mileage of your top five most distant stations.

A final point: this is not a contest; it is a challenge. The reward for every participant will be fun and fellowship.

UPDATE: Chuck Rippel did sweeten the pot, though! Check out his generous offer here.

Chuck Rippel “Sweetens the deal” on The Great Medium Wave Daylight DX Challenge!

by Jock Elliott, KB2GOM

After yesterday’s post appeared, Chuck Rippel reached out to me and offered:

To whomever logs the most stations using a GE SR-I or SR-II, I will donate that person, a >free< SR-I or SR-II restoration. Includes, parts, alignment, cleaning, etc…. The winner’s only cost will be shipping. Should the winner already have a radio I restored, I have an alternate “reward” in mind.

That is a very generous offer, Chuck, and I am sure someone will be the delighted recipient.

In the meantime, there is a very slight modification to the procedure for the challenge: I will be posting a reminder about The Great Medium Wave Daylight DX Challenge on Friday, and then on Saturday, I will post another The Great Medium Wave Daylight DX Challenge blog. That Saturday blog will be the place to post your results in The Challenge . . . .in the Comments section.

The Great Medium Wave Daylight DX Challenge

By Jock Elliott, KB2GOM

First a word of acknowledgement and thanks: it was Chuck Rippel who said (in part) — in response to this post — “We could make this interesting by restricting listening to the period 10AM – 2PM maybe 3PM.” And that got me to thinking that maybe a daylight DXing challenge might be fun.

It was Bill Hemphill, who said, responding to the same blog post:

“Every year the New Jersey Antique Radio Club has a BCB DX contest for its club members. The main purpose is to encourage the members to put into operation some of the many old am radios that they own. This year’s contest was just completed this past Sunday. For any 24 hour period, using the same radio, you attempt to log the most distant stations. The contest score is the total mileage of the ten stations that are most distant.”

Reading that, I rather liked the idea of using mileage as one way to keep score.

Combining the two ideas, the result is The Great Medium Wave Daylight DX Challenge.

Here are the rules:

Frequency rang is the medium wave band: 520-1710 kHz
10 am to 2 pm your local time on the Saturday after the post appears (Saturday, March 11, 2023).
Any radio with any antenna, but must be the radio at your location (no using remote internet radios)
The listener must hear the signal in real time

- Your location
- The time, the frequency, and the ID of each station heard
- The total mileage of your top five most distant stations.

A final point: this is not a contest; it is a challenge. The reward for every participant will be fun and fellowship.

The CCrane Skywave SSB 2 and long wire antennas

29 Replies

By Jock Elliott, KB2GOM

Frequently when people write about attaching a long wire to a portable shortwave receiver, readers will comment that you need to worry about desensitizing or overloading the receiver or ever harming the front end of the receiver. Clearly that can be a concern.

But recently I noticed something on the CCrane website in the FAQ section that shows clearly that CCrane has thought about and dealt with this consideration:

Q: When using the 2-wire adapter and wire attached, why am I not noticing any improvement on shortwave?

A: To see any difference using the 2-wire adapter you will need to have a wire that is more than 30 feet long (we recommend 60-100’) with a good ground wire. Insulated wire will last longer and should be stranded so it is more flexible. If you do not have a good ground, you are actually inputting noise. If you look at the 2-wire adapter (included) you will see an antenna icon and a ground (G) marking. You need to connect them properly when using an external antenna. When a plug is inserted into the antenna jack of the radio the internal rod antenna is disconnected. (See page 30 of the Instruction manual.)

If you check out my review of the CCrane Skywave SSB 2 you will read that I heard a noticeable improvement when connecting the SSB 2 to a 45-foot end fed wire.

Note, though, that if you plan to attach a wire to the SSB 2’s whip antenna, use the 23-foot reel antenna that comes with the radio.

A “knobs and switches” oldster investigates the SDRplay RSPdx . . . Wow!

46 Replies

By Jock Elliott, KB2GOM

It is hard to imagine a less spectacular looking piece of radio gear than the SDRplay RSPdx. It is literally a black box. Aside from the printing on top of the box, the most exciting thing about the RSPdx are the two red plastic covers on the antenna connectors on the side. There are no switches, no knobs . . . you can’t do anything to it except connect an antenna (or antennas) on one side and a USB cable on the opposite.

But once you connect the USB cable to your laptop and fire up the SDRuno software (that you have previously downloaded and installed), you are now in command of a listening post that covers from 1 kHz to 2 GHz.

We’ll get to the important stuff in just a minute, but first a little background.

For an oldster retrocrank like me, a proper radio has knobs and switches . . . preferably a knob or switch for every job. Lately, however, I have noticed that a lot of DXers and ordinary listeners are reporting good success with SDRs – software-defined radios. So I started to wonder about them.

There are three elements to a software-defined radio like the SDRplay RSPdx: the SDR box itself, which is the part of the system that actually receives the radio signals; a Windows computer (laptop or desktop), which provides the command and control for the SDR; and whatever antennas are required to receive the signals that the listener would like to hear. And, just to be absolutely clear, you need all three elements for the SDR system to work at all.

With my curiosity about SDRs rising, I inquired of Thomas, SWLing’s Maximum Leader, whether SDRplay – one of SWLing Post’s sponsors – might like me to take a look at one of their SDRs. Their answer was an emphatic Yes, and I had an RSPdx in my hands just a couple of days later at no cost to me or the SWLing Post.

I have to admit I had some trepidation about the process of bringing the RSPdx online because any time you have three different elements from three different sources that must work together for a system to function properly, there is always the possibility that some of the elements might not “play well together.”

Installation is easy and fast. Connect the RSPdx to the computer using a USB A-male to B-male cable (which the user must supply; often called a printer cable), then connect the antennas using the appropriate cable. In my case, I connected an MFJ 1886 Receive Loop to the Antenna C connector and an off-center fed dipole to the Antenna A connector.

To SDRplay’s great credit, they have produced an excellent video for first-timers and folks not familiar with SDRs — https://youtu.be/Oj_-dOLVzH8 . I recommend watching it, perhaps a couple of times, before you get started.

When you first fire up the SDRuno software, you will see the main panel:

Click on the “RX” button, and the Receive panel will be displayed. After you slide it over, it will look something like this:

Click on SP1 or SP2 in the main panel, and one of the peak displays will appear:

Finally, click on the PLAY button in the main panel, and whatever frequency you have selected will begin to play. Continue reading →

Saturday morning fun: “fat” MW DXing with the MFJ-1886

28 Replies

By Jock Elliott, KB2GOM

It was a reader, Mario Filippi, who set me on this path. He posted a comment that said, in part: “An interesting place to DX would be the segment between 1500 – 1590 kc’s where there are a number of news stations, one being federal news on 1500.”

Huh, I thought, federal news? I wonder if I can hear that. So I hooked up the MFJ 1886 Receive Loop Antenna to my Grundig Satellit 800 receiver and tuned to 1500. With the 800’s whip antenna, I heard mostly static; switching to the 50-foot indoor room loop, pretty much the same; same thing with the 1886 with the amplifier turned off. But turn the 1886’s amplifier on, and it was like getting slammed against the wall by the schoolyard bully: LISTEN TO ME! A big, fat, S9 signal, sounding like WGY 810 just a few miles from me. Wow, I thought, this loop can really pull out a signal.

A little research revealed, as nearly as I can tell, that Federal News 1500 is in Washington, DC, over 300 miles from me. Over the next few days I would occasionally check on Federal News 1500 using the 1886 loop, and typically it was loud and clear here in Troy, NY.

Hidden behind a curtain, the 3-foot aluminum loop of the MFJ 1886 works well for MW DXing.

Early this morning, Jan. 28, 2023, a thought crept into my brain: how many big, fat, MW signals could I detect with the combo of the Satellite 800 and the MFJ 1886 loop antenna? (Bear in mind that my 1886 rests flat against a window and is NOT rotatable in its current configuration.) Here’s the log, with station IDs when I could get them.

Time Frequency Station

1100Z 1520 WWKB Buffalo

1102Z 1530 Milwaukee? Sports, Australian open

1106Z 1540 CHIN Toronto, old time radio programs

1112Z 1560 religious music

1115Z 1660 orchestral music, Strauss waltzes

1118Z 540 middle eastern music

1121Z 660 WFAN, NYC

1124Z 700 WLW, Cincinnati

1127Z 710 WOR, the Voice of New York

1129Z 730 French language, Canada mentioned

1132Z 750 WSB, Atlanta

1134Z 770 WABC, NYC

1135Z 790 ortho doctor show

1138Z 860 French language, Canada mentioned

1140Z 880 WCBS, NYC

1142Z 1010 WINS, NYC

1144Z 1020 Talk

1146Z 1030 WBZ, Boston

1148Z 1050 WEPN, ESPN radio, New York

1149Z 1060 KYW, Philadelphia, PA

1153Z 1090 WBAL, Baltimore

1154Z 1110 WBT Charlotte, NC

Bottom line: it was immense fun, tuning around for “fat” MW stations in the early AM. Periodically I checked the other antennas as I traversed the band, but universally the MFJ 1886 was better at pulling them in.

Fat station DX? You bet! Try it; you’ll like it!

Surprise, Surprise!

If you had been monitoring 29.620 around 1615Z on January 5, 2023, it’s just barely possible that you could have heard me leap out of my chair and do the “Astonishment Dance,” while yelling: “Are you kidding me?!! Is this even possible?!!”

Let me set the scene: it was a quiet day, much like any other day. My Better Half was catching up with her sister on the telephone in another room. I was in the sun room/library/radio shack reading a book.

Two of my ham transceivers are ex-public-service units, and I decided to put the one dedicated to 70 cm on scan. In my area, 70 cm (440 MHz ham band) is generally pretty quiet, and I thought I would see if anyone was using it.

After a while, the scan stops, and the transceiver locks onto 442.9500 a repeater far to the south of me. A mellifluous French accent begins announcing a callsign: Foxtrot 3 Oscar India Japan. I drop my call on the repeater . . . KB2GOM . . . we chat. His name is Serge, he is in Rheims France.

Wait a minute, this is a 440 repeater. I’ve heard of extreme long distance propagation occasionally on two meters . . . but 440? This is crazy.

I am officially flipping out . . . is this some sort of X-files propagation on 70cm? Better call Fox Mulder.

I call my radio guru, K2RHI; he explains it is a 10 meter repeater linked to a series of other repeaters, including the 70 cm repeater my transceiver has locked onto. I settle down . . . a little . . . and continue to monitor. Then in rapid succession, I respond to the calls from hams from Texas, Northeast England and a place called Trout Creek in Delaware County. If you had been listening on 29.620, you might have heard one very excited oldster (me!) talking with those stations.

So dear reader, the moral of this story is two-fold: (1) you never know what surprise radio may deliver next, and (2) when it happens, it can be a source of fun and wonderment . . . so keep listening!
