What headphones do you use for your radio operation, and WHY do you use that particular make and model?

I use Audio-Technica ATH M30x professional monitor headphones (cans).

https://www.audio-technica.com/en-gb/ath-m30x

I use my rig’s filters to shape the audio.

1. I’ve replaced the over-the-ear pads with Gel pads. Wearing these cans is comfortable enough to use for extended periods of time (such as contests).
2. The mid-range with these cans is superior to other cans I’ve had.
3. They are rugged, so taking them out to the field isn’t a problem.

Guess what! Today, I received (by postal service) this very nice plaque from CQ, for working and confirming all 40 of the worldwide CQ DX Zones.

Many of you wonder, “where are my paper certificates for my WAZ efforts?”

At least one, if not all of the following, are reasons why there has been such a long delay in getting paper certificates for the WAZ CQ program:

1. Paper certificates (blanks) were not available and backordered (Covid, folks).
2. There is only ONE person doing the lettering (by hand).
3. The advent of FT8 and FT4 in the WAZ program has SWAMPED the program. There’s a HUGE backlog.

That said, the new CQ WAZ Manager (N4BAA, JOSE CASTILLO) has made the following statement available:

— quote follows —

Effective September 1, 2022, CQ Magazine will no longer provide the Hand Lettered CQ WAZ paper certificate for free.

CQ WAZ AWARD RECIPIENTS HAVE 4 AWARD OPTIONS:

1. Accept the standard award offering which is a High-Definition PDF file. This file can be printed in color and framed and is very nice. This award is delivered immediately with award letter, thus, no waiting.
2. Select the traditional CQ WAZ Hand-Lettered award: the cost is $19.00 and includes shipping worldwide. This award option is managed by CQ Magazine and can take up to 180 days to receive.
3. Select a Level I plaque: 7” x 9” two-tone engraved wood plaque: cost is $57 US / $100 International and includes shipping. Delivery time is under 30 days for US stations and less than 60 days internationally.
4. Select a Level II plaque: 9” x 12” Floating Etched Acrylic over Black Wood: cost is $91 US / $135 International. and includes shipping.

Here is a video that the administrator has posted, about this:

Delivery time is roughly 30 days for US stations and less than 60 days internationally depending on the actual address.

The intent of this program is to respond to the ever-increasing demand for more options that are still very personalized as well as very elegant.

Not every ham is able to achieve the requirements for a 5BWAZ or 160 Meter plaque, so he is making this offering to everyone!

All questions or inquiries and plaque orders should be directed to the CQ WAZ Manager via email at [email protected] or postal mail via QRZ.com address.

All plaque data will be taken directly from the information provided in your email. The CQ WAZ manager will not be responsible for errors in data supplied by the recipient other than AWARD type and Award number.

To Place Order: send the information below via email to [email protected] or via postal mail to my QRZ.com address and please double-check spelling etc.

Email Subject line should be: “WAZ PLAQUE ORDER – YOUR CALL”

Then, provide the following information:

Sure! You don’t need to have a software-defined radio (SDR) before you start learning how to use the technology; there are a few different paths you can take, exploring and learning about SDR.

One way to gain some experience with SDR without spending a dime is to install a free software package for the very popular, non-Linux, operating system (that starts with ‘W’), and give SDR a test drive. If you like it, you might consider getting your own hardware (like the SDRplay RSPdx, for instance), and connecting it up to your computer and running this software, too.

Why I Dived Into SDR

I have always loved radio, ever since the early 1970s, when I discovered shortwave radio. In the last couple of years, I’ve had an increasing interest in the world of SDR. When I am working, but away from home (remember those days, before Covid?), I want to sample news and programming from around the world, but through shortwave. The way to do that, I found, is by using the various SDR options which allow a person to tune a remote receiver, and listen.

I also find working with the waterfall of a typical SDR-software user interface rewarding because, instead of blindly searching for signals in a subband, I can see all of the received signals on the scrolling time representation of a slice of frequency. Simply select that signal on the waterfall, and the radio tunes right to it.

I often connect to different SDR radios around the world, to catch all manner of shortwave signals, from maritime, military air, trans-oceanic air, or coast guard radio traffic, or other interesting HF communications including amateur radio CW and SSB signals. Occasionally, I also check out VHF and UHF signals from around the world. All of that, while instead an office building that is not suited for shortwave radio reception.

I’ve now decided to give back to the community; I’ve added my SDR receiver to the collection of receivers located around the world on the SDRSpace network of SDR radios.

My new SDRplay RSPdx software-defined radio receiver is live, via http://www.sdrspace.com/Version-3, using the SDR Console software (Version 3).

The receivers are online whenever I am not transmitting and when there are no local thunderstorms.

Antenna Port A is connected to a wire antenna (a horizontal 100-foot wire that runs out from my house’s chimney to a tall tree; about 10 feet of that wire is oriented vertically, where the wire passes through a pulley and then is weighted down so it can move with wind-driven tree movement), while Antenna Port B is connected up to a VHF/UHF discone.

Both antenna systems have an AM Broadcast band notch (reject) filter reducing local AM Broadcast-Band radio station signals by about 30 to 40 dB. I need to use these because the very close KLIN transmitting tower is just miles away and those signals overwhelm the receiver. When I use the signal filters, the local AM Broadcasting signals no longer overwhelm the receiver.

In the following video, I first explain my SDR setup, and in the second half of the video, I tune around the radio spectrum, using the software to control my SDR receiver.

A Couple of Questions

After watching this video, WO9B wrote an email to me. Michael asked of me two questions, summed up as:

1. Your SDR window has the IF screen on top. How is that accomplished?

2. Your AM Broadcast filters; more info, please. I live in the area of mucho broadcast stations and that looks like something I could use.

In the following video, I demonstrate how I changed my layout of the SDR Console software. And, I mention the AM Broadcast Filter for SDR Receivers (the hardware filter is found here: https://g.nw7us.us/3kU5SJN).

To Use My Receiver

Download the latest version of SDR-Console from https://www.sdr-radio.com/download – there is a 32-bit and a 64-bit Windows installation package.

The 64-bit installation package may be downloaded from one of these three sources:

1. Google: https://g.nw7us.us/3auBq44
2. DropBox: https://g.nw7us.us/310ooIG
3. Microsoft: https://1drv.ms/u/s!AovWaZDu7Hrd3U-yqK1bs3wuaFw2?e=o4nKeh

The 32-bit installation package can be downloaded from one of these three sources:

1. Google: https://g.nw7us.us/3iLasrZ
2. DropBox: https://g.nw7us.us/3g4VcVc
3. Microsoft: https://1drv.ms/u/s!AovWaZDu7Hrd3U4mJiiRtI9lm70s?e=HDG4ZX

Install the SDR Console package according to the directions given. Once you have the software installed, you will want to add my server. It takes some work to get familiar with the software, but there are online FAQs on how to begin.

One guide on how to add a server to the list from which you can pick may be found, here:

https://www.sdrplay.com/wp-content/uploads/2018/02/SDRConsoleV3-ServerGuide1-1.pdf

I worked on getting all of the bugs worked out of my installation before making the video. It did take some work, and reading up on things. But, the software is solid and a good contender against SDRuno, and HDSDR, and, this way I can share it online with you.

My server is known as, ‘0 NW7US‘ — it will be online when I am not using my antenna systems for transmitting. It will be offline during thunderstorms, or during times when I must use the systems for transmitting.

Software-defined radio is a great way to hear all sorts of communications, from local AM broadcast stations, FM stations, VHF Air Traffic, to shortwave radio stations including amateur radio HF communications.

Man, lots and lots of Morse code on the ham bands, this weekend. The CQ Worldwide CW Contest weekend was hopping with signals!

How did you do this weekend? How were conditions on the various contest bands?

Comment here and your report may make it into the propagation column in an upcoming edition of the Radio Propagation column in CQ Amateur Radio Magazine.

Here are a few moments as heard at the station of the CQ Amateur Radio Magazine propagation columnist, in Lincoln, Nebraska (yeah, that’s me, NW7US).

What is the proper (and most efficient) technique for creating Morse code by hand, using a manual Morse code key? Ham radio operators find Morse code (and the ‘CW’ mode, or ‘Continuous Wave’ keying mode) very useful, even though Morse code is no longer required as part of the licensing process. Morse code is highly effective in weak-signal radio work. And, preppers love Morse code because it is the most efficient way to communicate when there is a major disaster that could wipe out the communications infrastructure.

While this military film is antique, the vintage information is timeless, as the material is applicable to Morse code, even today.

and creating more work for a QRP friend, Steve Fletcher G4GXL, over at QRP-ARCI (as if he doesn't have enough to do already - sorry, Steve!).

But did you know that if you're a paid up member of QRP-ARCI, that you can get QRP Quarterly as a .pdf file, sent to you?  Yes. you can! And it's real easy to do - here's the actual snippet from the QRP-ARCI Website:


Personally, I think this is fantastic and I offer kudos to Steve and QRP-ARCI.  I already get QST, CQ and the K9YA Telegraph in digital format, and now I can get the "Best of the Best" in digital format, too.

I know a lot of you prefer to have actual paper in your hands, but I like being able to have all four publications easily with me on my tablet. It takes up a lot less physical space, and I don't have to store back issues after the fact. And I've read so many books on my kindle and via the kindle app on other devices that swiping, enlarging, and dragging motions are almost like second nature to me now.

I suppose the fact that we save some trees in the process is a bonus too. Although, selfishly, I'm all in for the convenience! As far as storage goes, I have a dedicated USB memory stick where I already store back issues of the K9YA Telegraph. There's plenty of space on there for issues of QRP Quarterly.

Yes, I know there are downsides to digital formats of magazines. Of course, you need "juice" for the device's battery, and it's not as easy (or possible) to share or donate old issues to libraries or friends. But again, IMHO, these "cons" are minor compared to the "pros".  Whether we like it or not, it's more economical for the providers not to have to purchase paper, ink, binding, postage, etc. I would never say that actual paper publications will disappear forever, but this is (to use an overused phrase) "the wave of the future". And besides, if you're as old as I am (or older) who can forget the astronauts in "2001: A Space Odyssey" reading their news on a tablet like device.  Back in the 60s, when the movie came out, we all thought that would be so neat. That time is now, baby!

On another topic, remember how I mentioned in yesterday's post about FOBB that the weather forecast for Sunday would probably change between yesterday and then? It already has! Now it's looking like only clouds with no rain forecasted until well after FOBB 2015 is in the books. Looking better and better for heading out to Washington Rock State Park.
