What Headphones Do You Use, And Why?

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

Old Time Morse Code and Headphones

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

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.

Where’s My WAZ Certificate?

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.

CQ WAZ NW7US - Mixed

CQ WAZ NW7US – Mixed – Plaque

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.


  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 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 address and please double-check spelling etc.

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

Then, provide the following information:

Call Sign:
Desired Name on Plaque:
(example: MIXED, RTTY, 15M CW, EME, etc.)
Date on Award:
Award Desired:
– Level 1 plaque – $57 US / $100 International

Part 2 of 2: Life-changing Moment and Solar Cycle 25

From the RAIN HamCast episode #57, 2021-XII-25 (used with permission):

RAIN’s Hap Holly/KC9RP spoke with Tomas recently about Solar Cycle 25. This is the second and final excerpt from their discussion.

From the introduction to The RAIN HamCast, Episode #57:

In this episode, we continue our discussion with Tomas Hood/NW7US, the author of many writings about space weather and effects of solar activity the past 20-plus years.

(Part 1 of 2 can be found here: Episode #56,

Tomas has been a short wave enthusiast since 1973, a ham operator since 1990, and is a United States Army Signal Corps veteran today. He launched the first civilian space weather propagation website,, in the mid 90’s; HFradio later spawned; at press time is being revamped for the new Solar Cycle 25.

Tomas has contributed to the Space Weather Propagation column in CQ magazine for over 20 years, and for The Spectrum Monitor magazine since 2014. A product of the Pacific northwest, Tomas resides now in Fayetteville, Ohio.

Just Get On The Air! (A Makeshift Temporary Dipole Shortwave Antenna)

It might not take as much antenna as you may think would be necessary to make two-way contacts on shortwave radio (as an amateur radio operator putting an HF transceiver on the air). However, often, makeshift antennae are effective enough to be viable–just look at all the contacts many amateur radio operators make with their low-power (QRP) rigs (transceivers) using short, helically-wound, mobile antenna sticks. If they can work magic with such inefficient antenna setups, surely your effort at an antenna would pay off to some degree. Right?

Of course, I want to make a proper dipole out of this example antenna. But, while I wait for the rest of the parts I need to complete this antenna project (pulleys and a ladder, and maybe a potato launcher), I’ve put this makeshift antenna on the air, with it just high enough so that I can enjoy some time on the shortwave bands.

With this antenna, I’ve made successful two-way voice and Morse code contacts (QSOs) with stations in Europe and across North America. I am able to tune it on the 60-, 40-, 30-, 20-, 15-, 17-, 12-, and 10-Meter bands. Reverse beacon detection picks up my Morse-code CW signals, especially on 40 meters (the band on which it is tuned physically).

The bottom line: just get something up in the air and start communicating. Improve things over time. You’ll have much fun that way.

One Aspect of Amateur Radio: Good Will Ambassadors to the World

This article is part two of the series taking a look at band plans and gentlemen agreements.
See part one, here: Land (er, FREQUENCY) Grab.  See part three, here: In Response — Can’t We All Just Get Along?

Displaced and Marginalized

There are some unhappy amateur radio operators in the world of shortwave operations. Users of Morse code, and digital modes other than the highly-popular modes engineered by Joe Taylor, K1JT, feel displaced on the many amateur radio bands where Joe’s wildly-popular mode FT8 has erupted.

Joe (born March 29, 1941), is a friend of hams everywhere, and is an American astrophysicist and Nobel Prize in Physics laureate ( for his discovery with Russell Alan Hulse of a “new type of pulsar, a discovery that has opened up new possibilities for the study of gravitation.”

Many have asked questions like, “Did Joe Taylor K1JT Destroy Amateur Radio? Did Joe Taylor K1JT, Nobel Laureate and noted friend of hams everywhere, accidentally destroy amateur radio?” This question remains relevant, even as more and more FT8 operators take to the HF bands to chase wallpaper and awards.

FT8 Has Validity and Usefulness

Full disclosure: I administer a Facebook group for FT8 and FT8-related modes, because I believe that the mode has a valid place in our amateur radio technology portfolio.  Here is the Facebook group URL, if you would like to join the fun: Understand, I have used and will continue to use FT8.

Because it has a place, it stands to reason that everyone should become more aware of the impact of using FT8 on the bands. It also stands to reason that it should be used ethically, and in the best spirit of amateur radio.

Many amateur operators use the FT8 digital mode as a novelty when there isn’t much else happening on amateur radio shortwave bands. One of the great things about it is that you can tell when a band is open–even though you don’t hear any other signals of other modes on the band in question, you very well may hear the roar of FT8 on the band where propagation actually exists to somewhere else than your QTH.

Others use it to finally get their DXCC, or WAS, or other award and wallpaper. This is especially popular during this season of the sunspot cycle where there are no sunspots–propagation is limited to lower-HF amateur bands because there’s just not enough solar activity to energize the ionosphere enough to open up the higher segment of shortwave.

FT8 Has Limitations

Can FT8 be used for two-way conversations? No. However, the JS8CALL digital mode is designed from the FT8 mode, by changing the protocol in a way that allows free text. It is designed for ragchewing and the new version 2.0 offers three modes of chat with 50 Hz and 16 wpm, 80 Hz and 24 wpm, and the turbo mode at 160hz and 40wpm with turbo only having a 6-second turn around time. The designated frequency is 7.078, which many find much nicer to use.

However, many find JS8CALL combersome, and non-intuitive.  How fast and how reliably can it handle critical messages, say, during an emergency?  I’m sure the software will improve, but how good is the protocol?

A mode such as Olivia has been field proven, and time tested.  It can reliably handle traffic.

The Rant

During the early days of widespread FT8 operation that came with the first public non-Beta release of FT8-equipped WSJT-X software, I tried to reason with the FT8 development leadership team. I made a polite attempt at explaining how incredibly rude they were in purposefully programming into the software the default operating frequencies such as 7.075, 14.075, and so on.

One of the main leaders of that team slammed me and stated that “we only suggested those frequencies; the operator is free to change them.” Additionally, he stated that the team used a common QSO/Mode spotting website to see what digital modes or other operations (like CW) were sparser. They perceived that the frequencies they proposed where no longer active because they saw few if any spots. They thought that no one would care.

I explained that a single website-spotting strategy was illogical and very lazy. This is true for several reasons, at least.

I guess you have to have a Ph.D. to know better than any average ham who went by gentleman’s agreements. I have an extremely dim view of JT and his disciples. CW is not the only operating group he’s engineered out of traditional slices of spectrum. Olivia, and other modes, now have been pushed down into PSK subbands, and everyone is feeling the crowding. As far as my thinking of FT8, well, it is radio, but it doesn’t foster goodwill and building serious communications skill. IMHO.

Play Nice, Be Positive and Polite. Smile.

I’ve received wise counsel from a number of fellow amateur radio operators.  They implore us to not promote hostility between “us and them.”  That even though the WSJT team is playing the playground bully, we should not be vengeful, but polite and willing to negotiate in good faith.

If we don’t play nice with the bully then the bully won’t play with us.  And, the general public will side with the bully because the bully has the nice toys…

Good negotiations, though, take a willingness by both sides, so that conversation evolves,  resulting in positive, cooperative actions embraced by both parties. There are other amateur radio operators who have made attempts to open up talks with Joe and crew.  What are the results, so far?

We can hope that Joe Taylor and his group of developers and leadership take a proactive role and join a conversation that is with a wider group of amateurs than just the WSJT enthusiasts.  We hope that they will play fairly, and cooperatively, with the rest of the amateur radio community.

Contest Morse Code, Computers, and an Icom Rig

This past weekend (third full weekend in February, February 15-16, 2020) is the ARRL International CW Contest (ARRL DX CW link: ). This is interesting to my study of radio signal propagation as a columnist and as an amateur radio operator​ because of the contest objective: “To encourage W/VE stations to expand knowledge of DX propagation on the HF and MF bands…” This contest is a good way to get a feel for current propagation–though there are caveats.

Speaking of Morse code and the CW mode on our amateur bands: those of you using CW during contests, do you send by hand or by computer?  Do you copy the code by head, or do you use a computer for decoding?

Do you use a computer for Morse code operation?

Just curious about those of you who use CW. Do you send by hand or computer? Receive by head or computer?

In most contests like the ARRL DX CW contest, I copy by ear, and send mostly by rig keyer. If needed, I use a single paddle key with the Icom rig’s internal keyer to answer unique questions and so on.

Below is a quick demo of using the internal Morse code keyer in my Icom IC-7610 transceiver.

V47T, in the Saint Kitts and Nevis Island in the Caribbean, is calling CQ TEST in the ARRL DX CW contest.

Using the programmable virtual buttons, in which I programmed my callsign, NW7US, and other info, I answer and make a complete contest QSO.

In activity like the Straight Key Century Club (SKCC – K3Y special event, it is all manual. I send my Morse code using a WWII Navy Flameproof Signal Key, and decode with my ears.  It is contextual for me.

How do you do contesting Morse code?  Bonus question: How do you do logging while doing contest operation?

How Did You Fare in CQ WW CW Contest Weekend?

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).

Here are the results of my dabbling with the Icom rig and this contest:
