Short Demonstration of Using Ham Radio Deluxe with WSJT-X and FT8 Digital Mode
Ham Radio Deluxe can log your WSJT-X FT8, JT65A, and JT9 QSOs, via the JT-Alert software. This is a demonstration of my use of HRD and Logbook, during an FT8 QSO,today.
As some of you know, I have had some differences of opinion regarding the selection of frequencies chosen by the FT8 creators and advocates. Regardless, I do still use the mode. Here is proof:
Go ahead and share, if you would. And, please subscribe to my YouTube channel, as I will be creating many how-to videos in the near future.

Opinions About ARRL Petition to FCC: Expand Technician HF Privileges!
In this video, I expound on another point of view regarding the ARRL petition to the FCC. The petition requests an expansion of operating privileges of Technician-class operators in the USA. The ARRL believes that giving broader shortwave access, using digital communications, to Technicians, will better entice the Techs to upgrade to General or Amateur Extra. In this video, I discuss this a bit.
If you are wondering why I’ve made a few videos about this topic, when the topic has been the hot item on many forums already, I believe that the drama will not cease until well after the FCC makes a decision, because this is a relevant topic, and one that has a significant impact on the amateur radio community at large. It is not a trivial conversation about which type of coax is best suited for Arctic field activity.
After some replies came from various viewers, I clarify my point. I stand corrected.
I failed to mention that there are a limited few slices of VOICE (SSB) spectrum on HF that the petition seeks for the Tech licensee. The ARRL states, “ARRL has asked the FCC to expand HF privileges for Technician licensees to include limited phone privileges on 75, 40, and 15 meters, plus RTTY and digital mode privileges on 80, 40, 15, and 10 meters.”
More specifically, “ARRL proposes to provide Technician licensees, present and future, with phone privileges at 3.900 to 4.000 MHz, 7.225 to 7.300 MHz, and 21.350 to 21.450 MHz, plus RTTY and digital privileges in current Technician allocations on 80, 40, 15, and 10 meters. The ARRL petition points out the explosion in popularity of various digital modes over the past 2 decades. Under the ARRL plan, the maximum HF power level for Technician operators would remain at 200 W PEP. The few remaining Novice licensees would gain no new privileges under the League’s proposal.” Reference: http://www.arrl.org/news/arrl-requests-expanded-hf-privileges-for-technician-licensees
My point holds: give some reason to desire to upgrade to a higher class. Do this by granting HF operations on lower bands (lower in frequency than 10 Meters), with more than a CW-only privilege.
If a tech can only use CW on 80m, but doesn’t know CW, then it is likely she won’t ever try making contacts on 80m. Hence, no exposure to the magic of 80-meter DX. If, however, the Tech can dabble with digital or limited SSB, on 80m, then she gets a real, practical exposure to the magic, and may well upgrade. Why do you think a General, who has limits, would ever upgrade? What am I missing here?
The following video expands this idea:

The truth is, I see a strong argument for just ONE license, permanent. Or a temporary entry-level training ticket, then the permanent. But, that would make us like some other countries. That can’t be good.

Travel Footage: 3Y0Z Antarctic Bouvet Island DXpedition 2018 Expedition (by EY8MM)
Here is video footage of the journey to Antarctic Bouvet Island, made by the 3Y0Z amateur ham radio team. This footage caught a few moments on the deck of M/V Betanzos.
As you can see in the last moments of this footage, the weather conditions contributed to the decision to abort the DXpedition, as it was far too dangerous to continue this expedition.
As reported by ARRL:
“Our captain has decided that it is in the best interest of safety and expediency to proceed directly to Capetown, South Africa, rather than Punta Arenas, Chile. We are now heading north to avoid the possibility of encountering ice. Currently, there is no ice in sight or on radar. In due time, we will head easterly toward Capetown. Our entire team is safe. Most are resting in their bunks and in good spirits. We will keep the amateur radio community and our families informed, as we continue our journey.”
In a huge disappointment for the DX community and the members of the 3Y0Z Bouvet Island team, the DXpedition’s leaders announced at 2000 UTC today (February 3) that a decision had been made to abort the DXpedition and head back to Chile.
“During the last 72 hours, we continued to experience the high winds, low clouds, fog and rough seas that have prevented helicopter operations since our arrival at Bouvet,” said an announcement on the 3Y0Z Bouvet Island website. “No improvement was predicted in the weather forecast for the next 4 days. Then, last night, an issue developed in one of the ship’s engines. This morning, the captain of the vessel declared it unsafe to continue with our project and aborted the DXpedition. We are now on our long voyage back to Punta Arenas. As you might imagine, the team is deeply disappointed, but safe. There is already talk about rescheduling the DXpedition.”
Bouvet Island currently is the third most-wanted DXCC entity, behind Kosovo and North Korea. The 3Y0Z DXpedition, comprised of top operators with considerable DXpedition experience, has been in the planning stages for 2 years and had attracted contributions from clubs and individuals around the world.
A dependency of Norway, Bouvet is a subantarctic island in the South Atlantic. The last Bouvet activation was 3Y0E, during a scientific expedition over the winter of 2007-2008.

Let’s Call CQ – QSO Today Episode 184 with NW7US
I got a Skype call a few weeks ago from Eric, 4Z1UG–the creator and host of the QSO Today Podcast–during which he asked me about how and why I got into amateur radio. Here’s the result.
Eric writes,
We talk a lot about the band conditions due to the Sunspot cycle. Most of it on Facebook and other places is about how “dead” the bands are at this point. We all can’t wait until the cycle starts to rise and we will be making contacts with little effort. I remember in my conversation with Chuck Adams, K7QO in Episode 58, that he really enjoys operating is “Pigrig”, one watt, CW transceiver on 20 meters. When I asked him, (I liberally paraphrase) “but Chuck, the bands are dead. How does that work for you?”. His reply was that while most hams are listening to the bands, he calls CQ until he gets a reply. Works every time.
My QSO this week is with Tomas Hood, NW7US, who has years of expertise in propagation and Solar activity. He is the propagation editor of more than a few radio magazines and websites. In our post-recording conversation we discussed this phenomenon of listening and not calling CQ. I even had this idea that maybe one of the reasons that the digital modes are so successful is because they “beacon”, as part of the whole digital experience, the same as calling CQ. This is why they make contacts. From what I see, looking at PSK Reporter, hams are making lots of contacts worldwide using the digital modes. While SSB may not be working so well, CW and the digital modes seem to work fine.
I like to work on my bench or make the podcast while listening to the bands. Jeff Damm, WA7MLH, in Episode 177, says that he will put his keyer in CQ mode while he is working on a new radio. Invariably, sometimes after many minutes, he gets a reply. Great idea Jeff!
73,
Eric, 4Z1UG
Episode 184 can be found here: https://www.qsotoday.com/podcasts/nw7us
Highlights of Episode 184:
Tomas Hood, NW7US is the propagation editor of a number of shortwave and amateur radio magazines, and has a wide variety of websites, that grew out of his love for all things radio, and for listening on the bands to far off DX and commercial broadcast stations. Tomas shares his understanding of propagation and the lessons we can learn from listening, really listening to the QSOs and exchanges during contest operation.
All of the QSO Today episodes are great. I enjoy hearing about many different hams. Do check out all of the episodes that Eric has published.

What Got You Interested in Radio? What Hooked You? (Story Time, with Video)
What got you interested in radio? What hooked you?
I’ve been asked, “What got you interested in radio, space weather, and the science of radio-wave propagation?”
Here’s a short answer as to why (and when) I became a radio enthusiast. It all started…
[embedyt] https://www.youtube.com/watch?v=0XBth62JgwA[/embedyt]
https://www.youtube.com/watch?v=0XBth62JgwA
The following picture is of my first shortwave radio, discovered in my home sometime between 1971 and 1973: a Sony portable transistorized four-band radio receiver. This was my very first shortwave radio (well, truthfully, it was my dad’s). This radio is responsible for my love of radio, electronics, and communications.
I still use this, sometimes, when listening to late-night AM-broadcast-band-radio DX. It is horrible for shortwave radio listening, as it has no noise blanker. For MW (Medium-wave) AM Broadcast DXing at night, it is excellent. The internal bar antenna is very directional so I can rotate the radio around until I get the best reception of some station. Back when I was a child, that made the radio very fun to use.
This next radio is a really capable military surplus radio circa WWII or shortly after (the late 1940s, early 1950s). This radio was my world starting around 1975. From Medium-wave to Shortwave, this radio could hear a pin drop around the world! Many late nights when I was supposed to be sleeping, I was up with the light dimmed and the tubes singing signals from exotic places.

Demonstration: Using FLDigi to Communicate with Olivia Digital Mode on Shortwave
Are you interested in starting out with the amateur-radio digital modes on the high frequencies? Have you heard of FLDigi? FLDigi is a software control and modem suite that interfaces with your transceiver, your computer sound card, and other input/output interfaces so that you can receive and transmit one of many digital modes. For example, FLDigi allows you to operate using the Olivia digital mode.
Unlike the JT/FT digital modes–modes that do an incredible job under marginal propagation conditions–there are other modes that offer keyboard-to-keyboard conversational QSO opportunities that can overcome rough shortwave radio propagation conditions. (The meaning of QSO on Wikipedia: An amateur radio contact, more commonly referred to as simply a “contact”, is an exchange of information between two amateur radio stations.)
While making quick work of getting DX stations into your logbook by exchanging callsigns, a signal report, and a grid square, the JT/FT modes (JT stands for Joe Taylor, the fellow that pioneered these modes) are limited. They cannot handle any additional communications beyond a callsign, a signal report, a grid square, and a very limited set of acknowledgments and sign-off messages.
When you desire to get to know people from other areas of the world, or if you need to establish networks around the world for passing information–perhaps an emergency net in support of the Red Cross–or if you are motivated by any other of a myriad reasons to establish a keyboard-to-keyboard conversation by way of the ionosphere, modes like Olivia are great candidates for your consideration.
In this video, contributing editor with CQ Amateur Radio Magazine, NW7US shares some starting points in the FLDigi software for Olivia keyboard-to-keyboard chat mode.

Current CENTER Frequencies With 8/250 in MHz:
1.8269, 3.5729, 7.0729, 10.1429, 14.0729, 18.1029, 21.0729, 24.9229, 28.1229, and so on. See the pattern?
By the way: The current suggested CENTER frequency With 16/1000 or 32/1000 on 20 meters is 14.1059.
(Why the …9 frequencies? Experts say that ending in a non-zero, odd number is easier to remember!)
Q: What’s a ‘CENTER’ Frequency? Is That Where I Set My Radio’s Dial?
For those new to waterfalls: the CENTER frequency is the CENTER of the cursor shown by common software. The cursor is what you use to set the transceiver’s frequency on the waterfall. If your software’s waterfall shows the frequency, then you simply place the cursor so that its center is right on the center frequency listed, above. If your software is set to show OFFSET, then you might, for example, set your radio’s dial frequency to 14.0714, and place the center of your waterfall cursor to 1500 (1500 Hz). That would translate to the 14.0729 CENTER frequency.
