To: All ARRL Directors and Officers

From: NW7US

Many actions–policy and governance–taken by the League’s leadership over the past two years trouble me. Formalization of specific actions planned for the Board meeting on January 19, 2018, specifically worries me.

At this time, any action taken by the ARRL Board of Directors cause me concern. As a result of this, I add my name to those seeking that the Board delay consideration of any ByLaw changes at the January 19 Board meeting.

In particular, I strongly urge you to:

1. Reject any proposal to allow the President and individual Vice-Presidents to vote as Directors.

2. Reject any provision that allows expulsion of an ARRL member “for cause” without delineated criteria.

3. Reject any provision that allows expulsion of any Director, Vice-Director of Officer for bringing ARRL into “disrepute” without specific criteria.

4. Reject any provision that reduces Members’ ability to recall a sitting Director.

5. Reject any current or proposed provision that allows the Board to disqualify candidates for elected office without full disclosure of the reasons for such disqualification.

6. Reject any proposal that would allow the Board to designate replacements for Directors instead of appointing an elected Vice Director or other elective processes.

7. Reject any current or proposed provision that allows censure, removal or other disciplines of a Director for revealing or openly discussing any view expressed at a Board meeting that is not consistent with the Board’s action.

8. Adopt a policy that elected Directors, and Vice Directors are not “personnel” for the purposes of declaring that any information about removal or disqualification is confidential and may not be released.

It is crucial that ARRL remain a solidly democratic, membership-based organization with principles of openness and accessibility through our elected Directors. I urge you to vote per my wishes at the January 19 meeting.

Beyond these issues of governance, I am concerned about the policy-making process of the ARRL leadership–leadership that I feel has become much less Member-driven, and that no longer reflects the needs of the Membership.

Ham radio is in a time of transition. The ARRL must focus on the issues that make a difference for the future success of the hobby.

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.

Demonstration: Using FLDigi to Communicate with Olivia Digital Mode on Shortwave

Demonstration: Using FLDigi to Communicate with Olivia Digital Mode on Shortwave

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.

Over and (not quite) Out – KN4AQ and HamRadioNow

[this blog entry originally… well, seconds ago… appeared as a QLOG blog post on the HamRadioNow.tv web site]

If you watched all of HamRadioNow 377, BS#11: ARRL, CQ, Happy New Year you saw my most direct statement that I’m going to leave the show in the hands of my co-host (now full host) David Goldenberg W0DHG. Thanks for the many comments about the show so far, and the ‘don’t go’ requests.

When I finished that show, I felt kind of sad. I’d be sadder if it were really my last show, but I’ll be around a while longer. I’ve committed to go to Orlando in February with a booth in Commercial 3, and I’m planning on a SIB (Studio In a Booth) there. It’ll be nicer than tent city in Xenia. I’m also planning on going to Dayton to shoot some forums, but no booth. Maybe a little tour. The 2018 TAPR DCC in September will depend on a pretty expensive KICKSTARTER (I’m guessing $8000) that I’ll run in June.*

David is getting close to finishing the ‘West Coast Studio’ and being able to run shows on his own. Then the show will take his direction entirely. I’ll be happy to show up as a co-host now and then, but I’m eager to see how David develops as an ‘on-air talent’. It will put him on level ground with most of the other ‘HamCasters’ out there who didn’t come from a professional media background. Only a few did – I’m thinking of Don Wilbanks AE5DW (Ham Nation and Newsline), Valerie Hotzfeld NV9L (Ham Nation), Cale Nelson K4CDN (Ham Radio 360), Neil Rapp WB9VPG (HamTalkLIVE), and some more of the Newsline contributors and anchors who don’t do podcasts. I probably missed a few, and OK, that’s more than I thought, but there are a lot of shows out there by ‘amateur amateurs’.

As I mentioned on the episode, I’ve got plans for a show that’s not ham radio related. My own background started in the ‘general media’ broadcast biz, with stints on-air at several radio stations. I always preferred doing that, but always made a far better living with my video and audio production talent than my on-air talent. I almost got hired to do a talk show out of WMBD radio in Peoria IL in 1986. I could have been Rush Limbaugh instead of Rush Limbaugh, and the whole political landscape could be different today. So it was my fault. OK, dream on, and Rush started his talk show in Sacramento CA in 1984, so I would have had some catching up to do. I didn’t take that job, and it’s a longish story. But coulda woulda.

As I dipped my toe into producing some ham radio videos, I didn’t appear on-camera much. I did short on-camera intros for The Last Big Field Day and Digital Voice for Amateur Radio DVDs, but the rest was voice-over, with the usual ‘invisible producer’ interviews. Even my first Hamvention Tour DVDs starting in 2007 used Jeff AC4ZO on camera more than me. It took a while to build the confidence to step into the spotlight completely.

One of my goals when I started ARVN:Amateur Radio//Video News… a clunky name that became HamRadioNow… was to get more professional video media into ham radio. At the time, ham media was mostly magazines, while video/television was seeping into corporate communications and other non-broadcast interest areas.

CQ had tried making some videos (professionally produced, and released on VHS) in the early 90’s. Video production was extremely expensive back then. A decade later, when I bought a camera and shot The Last Big Field Day, it was DIYish (after spending about $15,000 on my first camera/mic/editing system). I didn’t know it, but George W5JDX was starting AmateurLogicTV about the same time, with way cheaper gear and lower production ‘values’, and putting it on the web instead of DVD. I missed that boat for almost a decade

Before starting, I sought advice from two friends in ham media. Rich Moseson W2VU, who produced the CQ video series and went on to become CQ editor, discouraged me. He considered the CQ videos an expensive and somewhat failed experiment—failed in that they weren’t embraced by the ham community enough to be commercially profitable. Let’s put it this way: they didn’t go on to make a second series. At that time (early 90’s), video production was either really bad amateur stuff (badly shot and edited on VHS), or very expensive professional work. CQ opted for pro. I think it would have looked bad for them to do take the schlock route.

Bill Pasternack WA6ITF (SK), on the other hand, was highly encouraging. Like me, Bill (co-founder of Newsline) had longed to see ham activities documented more professionally. Newsline was a shoestring audio production. It was all volunteer, with just enough financial backing from the audience to keep it limping along year-to-year.

Bill was also part of the team that produced a handful of ham radio films (yes, films), with Roy Neal K6DUE and Dick Van Dyke, and later one with Walter Cronkite, mostly a labor-of-love with modest financial support from the ARRL. As a broadcast video engineer, Bill saw ‘pro-sumer’ video equipment getting better and cheaper, but he was frustrated that the Amateur Radio Today video he produced with Cronkite had little actual footage covering ham operation, particularly EmComm (the video focused on California fires that year, and they had to stage much of what they used). Bill dedicated one of his Town Hall forums at Dayton to encouraging hams to shoot and edit video with the new tools whenever and wherever they could, especially during EmComm operations. So far, that’s not happening.

Bill believed that someone with my technical background could maybe pull it all together. I miss Bill. I was looking forward to many more BS episodes with him on HamRadioNow.

Neither Rich nor Bill was fully right or wrong. Production get did get cheap enough that I could produce videos that looked as good as CQ’s series for probably 10% of their cost. But the ham community still did not embrace them enough to make them a business. My goal (and Bill’s hope) was for a program that could document and present ham radio professionally, both for ham ‘internal consumption’ and to provide grist for the general media mill to tell our story. It wasn’t happening.

Ham Nation appeared on the TWiT network in 2011. Bob Heil brought in one of Ham Radio’s biggest ‘stars’, Gordon West WB6NOA, and asked me to guest-host when he was on the road. Then he discovered George W5JDX from his Amateur Logic series. I suggested they try to incorporate Newsline into the program with a short peek at upcoming headlines, and initially Bob Sudock WB6FDF did the job (but it was never ‘upcoming’ headlines. It was and still is leftovers from the previous week. Have I mentioned that video production takes time?). Bob had health problems, and the Newsline job fell to Don Wilbanks AD5DW. Don’s a total pro, and quickly became a regular part of the full show. I’ll say that Don ‘took my job’ as guest host and leave the long story at that.

I’m gonna also say that in some ways Ham Nation ruined ham radio’s chance at the professional production Bill Pasternack and I had hoped for. The popular show sucked much of the air out of the room for ham media with a low-production-value happy-talk style that put ‘amateur’ back in ‘amateur’ (OK, it never really left). They do some Skype interviews, sometimes newsworthy and sometimes really interesting, but never hard-hitting. They get some videos contributed by viewers with variable quality (and for the ‘big’ show, they don’t get flooded with videos). The most popular segments are about building stuff, a ham staple that lots of other shows rely on and I’ve stayed mostly away from (my Episode 82: Dipole with over 32,000 views is among my most popular, so no, I don’t learn lessons). We don’t know how popular Ham Nation really is because TWiT doesn’t release statistics. Their YouTube channel shows view counts in the 2 to 4k range (with spikes above that), but YouTube is only one outlet, and if that’s just a fraction of the viewers and listeners, we’re looking at 10k or more… maybe in the 20 to 30k range.

TX Factor

There is one show out there that does produce very professional ham media: TX Factor. It’s a British production that began in February 2014. While they cover the usual ham stuff, they do it in a magazine show style (three to five segments in their 40 to 60-minute show… they’ve been getting longer…) that are all shot on location, edited and packaged. It’s a lot of work, as evidenced by the fact that in four years they’ve produced only 19 episodes. They also shy away from controversy, though they’ll occasionally note that something is a bit off here and there.

ARRL… QST-V?

I didn’t intend to do a full media review when I started writing this blog entry, but I should mention the League’s lack of participation. They’ve made a few video programs in addition to equipment reviews and now the Doctor Is In podcast (excellent, by the way). But they’ve never built a TV studio or produced a regular video program, even though they concentrate almost everything going on in ham radio in one building in Newington (and could Skype in the rest). Nor do they go out of their way to get their staff to appear as guests on the many talk-format shows out there. I was able to get some of their leadership on HamRadioNow for a while, but that seems to have stopped when I proved not to be a reliably friendly venue.

Money is a issue at HQ, but I’ll just say that if I can do it with my limited, individual resources, it’s not the main issue. Clearly they don’t see value… a cost/benefit calculation. At least not yet.

Meanwhile I have seen some good stuff from the RSGB (with help from TX Factor). Nothing regular yet, but more than the League has done.

The one area that has consistently produced high-quality video programs are the ones coming from DXpeditions. Not all are top notch, but Bob Allphin K4UEE and James Brooks 9V1Y have led the field in all amateur radio video production. And I’m not saying that just because I edited Bob’s Navassa DXPedition video. And sorry, they’re not online. You gotta buy the DVDs (a few of the old ones have found their way to YouTube). You can watch James’ excellent WRTC 2014 documentary online. That this is the case shows where the money is in ham radio media.

So as my car on the HamRadioNow train approaches the terminal, I’ll say that it’s been very rewarding (emotionally, not financially). I look back over the nearly 400 shows (over 400, if you count the many multi-part episodes), I can’t believe where I got the ambition to do it. And I’m generally happy (sometimes very happy) with my ‘performance’ on-camera. Happier than most of you are, it seems. It is a vanity and ego-driven business, after all. I’m sorry I didn’t get to do what I set out to do – the documentary style programs that TX Factor does – here in the US. I’m sorry that nobody in ham radio has found a way to make a business out of ham video, and maybe the hobby is just too small for that. Maybe it’s just not possible, and all our ‘new’ media will continue to be in the DIY/vanity category.

But I’m not sorry I tried. If I hadn’t done this, I probably wouldn’t have tried doing what’s next.

73, Gary KN4AQ

*And I’ll leave it to motivated TAPR enthusiasts to promote and make the KICKSTARTER successful. It’s not that I don’t want to go, but at this point it will be a business proposition that covers expenses and editing (highly discounted editing). Think of it as you’re hiring me to do it, not that I’m just asking for some support.
