What is the most important aspect of life?  Having fun! (Of course!).

Perhaps it is unusual to wax philosophical in an amateur radio forum, but I am going out on a limb to share a perspective that hopefully is refreshingly new and full of life:  Systems thinking — an amateur radio approach.

What I’m sharing herein, I find very intense, invigorating, challenging, and motivational! The more I think about amateur radio with this perspective–the Systems Thinking perspective–the more fun I’m able to define, and then accomplish.

In my opinion, this approach to life is REVOLUTIONARY! Why isn’t this knowledge distributed far and wide?  Why aren’t these precepts taught in the schools for young children, so that they can be equipped for a life full of accomplished purpose?  Perhaps it is due to the deceptive simplicity of approaching life with the perspective of Systems Thinking.

SYSTEMS THINKING AND AMATEUR RADIO

Amateur Radio as a Service – a System, not a Collection

What is Systems Thinking?

In a very simplistic sense, a system is any group of parts that make up one complex whole.  Each part cannot function as the whole, and each part interacts with other parts, such that this behavior affects that end result which is expressed by the whole.

Think about a motorcycle.  Let’s play with that thought: I disassemble my motorbike in your living room.  Once the bike completely taken apart and the parts are scattered all over your living room floor, can any one of those parts support my riding it out to the countryside, and back again?  No.  Only the bike can act, when it is made whole again, as a motorbike.  But, even if the individual parts, doing their part well, try to be the bike all by themselves, but fail, in the end realize that the parts are very important.  Each part has a place and a job.  Each part belongs.

By now, as you think about this, you probably realize that there is a difference between collections, and systems, of course.  A bag of rocks is not a system.  A motorcycle is a system.  A bag of motorbike parts is not a motorbike.  The assembly of the motorbike parts does make a motorcycle.

What does this have to do with amateur radio?

The amateur radio service (hobby) is a system, not a collection.  There are many parts–and one of the most important component of the amateur radio system is you and me.  We interact with each other, exchanging knowledge, reports, friendships; we each function, lending our functioning the the autonomous self, the amateur radio service.

It takes more than one of us to make up the amateur radio service.  It would take at least two amateur radio operators, at the most extreme emaciated existence as a public service. It is obvious that one ham, all by herself, does not make the amateur radio service.  No one of us is the amateur radio service, by ourselves.  We need each other in order to have a ham radio community–the amateur radio service.  Ourselves, our radios, antennas, computers, knowledge, schedules, and so on, are all parts of the big system with which we participate in our community.

Let that sink in.

Ponder the long-term repercussions of this revelation:  We need each other, and we need our resources (time, skills, knowledge, radios, etc.).

How do we shape our System?  What will elevate our System so that it is effective?  And, so we begin to do this, SYSTEMS THINKING.

Please read, and ponder these thoughts, as you read through this article:

Addendum:  I do not necessary agree with every perspective, conclusion, or point made by Dr. Russell Ackoff.  Never-the-less, the overarching idea of systems thinking seems valid, and is worth considering.

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:

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.

Amateur radio often helps out in emergencies. But hams have other lives besides what’s they’re licensed to do by the FCC under the Amateur Radio Service. One prominent ham, Dr. Scott Wright K0MD, edits the American Radio Relay League’s National Contesting Journal and contacts many, many other hams in official contests. But in his work life as a physician at the prestigious Mayo Clinic in Rochester MN, he regularly saves lives as a cardiovascular physician. But now Dr. Wright and a fellow physician and ham operator, Dr. Peter Marx of the US Food and Drug Administration (call sign AB3XC), are engaged in a much broader life-saving activity during the Covid-19 pandemic.

Convalescent plasma is the only antibody based therapy currently available for COVID-19 patients. The US Convalescent Plasma Expanded Access Program is a collaborative project between the US government and the Mayo Clinic to provide access to convalescent plasma for patients in the United States who are hospitalized with COVID-19. The study, goals and explanations for what convalescent plasma is can be found on the official website: www.uscovidplasma.org.

 If you would like to participate, please contact them at [email protected]

www.uscovidplasma.org

“My role is to organize the infrastructure, the research approach, help lead the set up of the data collection teams and the website teams while overseeing the study conduct and regulatory compliance,” said Dr. Wright. The study started in early April under the leadership of Michael Joyner, MD of the Mayo Clinic, R Scott Wright, MD of the Mayo Clinic, Peter Marks, MD, PhD and Nicole Verdun, MD of the US FDA and Arturo Casavedall, MD, PhD of Johns Hopkins University. The regulations governing the treatment of human subjects in research studies are substantial and required by law.

Peer-reviewed publications are already rolling out of this fast-paced medical team. The first safety report on 5,000 patients was published in May in the Journal of Clinical Investigation and the most recent safety report on 20,000 subjects published in the Mayo Clinic Proceedings this past week. Dr. Wright added, “The FDA will be making an announcement in a week or less about the benefit of convalescent plasma. We are working on a third publication now to submit to a major international medical journal for publication on whether the study has shown that use of convalescent plasma reduces mortality.” Dr. Peter Marks and Dr. Nicole Verdun are the leaders at the Food and Drug Administration.

The work of this study has been on top of my regular day job, and has been intense and required working daily including weekends for all of April, most of May and all of June so far.

Dr. Scott Wright, Mayo Clinic and Editor, ARRL National Contesting Journal

The ability of team members like Dr. Wright and others at the Mayo Clinic to move at this fast pace has been remarkable. Most studies of this magnitude take months to a year with planning and execution to initiate the scientific study. Dr. Wright said, “We started in less than a week. Most studies recruit 2500-5000 patients. We have recruited over 30,000 patients in 10 weeks, exceeding all expectations. We have hospitals in all 50 states and several US territories who are participating and over 8000 physician scientists who are working with us as investigators at their hospitals. We also helped manage the start up of collection of convalescent plasma by the large blood organizations like the American Red Cross and others by strategically connecting donor pools and people willing to donate with the blood collection centers. The work of this study has been on top of my regular day job, and has been intense and required working daily including weekends for all of April, most of May and all of June so far.“

Convalescent Plasma

Program participation

June 30, 2020

“Dr. Marks and I love our hobby of amateur radio. But this study draws on our professional work and our compassion for our fellow human beings. The Covid-19 pandemic has been a shell-shock for me as I’ve worked the Emergency Room at Mayo Clinic. The Convalescent Plasma Program is clearly saving lives and preventing some of the terrible outcomes of the Covid-19 virus. I’ve had to hand over some of my editor duties at the League’s National Contesting Journal to another ham operator so as to meet the expectations of both roles. Dr. Marks and I, along with our complete team including Dr. Casavedall of Johns Hopkins University and Dr. Joyner, our program leader at Mayo, are very optimistic that the intervention work in the clinical setting and the research publications that emerge from the Program will continue to make a different in the lives of all who are threatened by this deadly virus,” concluded Dr. Wright. The Amateur Radio Code beckons us to balance our hobby with our other callings. These two ham operators are living that Code daily now.

He also added for the ham radio community, “I will be the keynote speaker at the QSO Today International Ham radio Fair in early August talking about the study, its results, etc.,. and linking it to skills acquired through ham radio.” If readers are not yet familiar with the QSO Today Ham Radio Expo, please visit the website for that event. Registration is free and Scott’s Keynote Address will kick off the Expo with how amateur radio helped him take a leadership role in getting this major medical program up and running in record time. Just like amateur radio does in most emergencies. Except on a much grander scale in this case.

This article is part two of the series taking a look at band plans and gentlemen agreements.

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 (https://g.nw7us.us/2Ptquv1) 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: https://www.facebook.com/groups/FT8.FT4.HF.6m/. 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.

We’ve all heard it at least once:  no one owns a frequency.

By law, amateurs must keep the transmissions from their station within the bounds of the allocations granted to license-holding operators–within these bands that are allocated for amateur radio use.  Amateurs are expected to follow band-plans, which guide us to which mode can be used in a band.

Subbands — Band Plans

There are many decades of constant refining of the standard operating procedures–perhaps we can call them, traditions–that, for the most part, work out pretty well for most amateur radio operations on our precious allocations in the radio spectrum.  Each band–a slice of radio spectrum between a lower frequency and a higher frequency–is made up of subbands.  These subbands are slices within a specific band (allocation), in which amateurs participate in two-way communications by using a particular mode of transmission, like single side band or CW.

For instance, Morse code enthusiasts use CW (continuous-wave modulation, i.e., A1A) between 14.000 MHz and 14.150, which is the subband that exists in the larger allocations known as the 20-Meter Band.  The 20-Meter Band is 14.000 MHz to 14.350 MHz, and the regulating bodies (such as the FCC in the USA) have directed through law that voice modes cannot be used between those subband frequencies from 14.00 MHz to 14.15 MHz. Voice modes can be used from 14.15 MHz up to 14.35 MHz, with certain license class variations. Read the PDF from the FCC: FCC ONLINE TABLE OF FREQUENCY ALLOCATIONS

CW is not the only mode allowed in the 14.00-MHz-to-14.15-MHz subband.  The regulations stipulate that a number of data modes can be used in this subband. There are specific requirements that a mode must meet, in order to comply with regulations–these are known as the authorized emission types.

Gentlemen’s Agreements

Amateur radio operators, decades ago, began discussing, then agreeing to, agreements between all operators as to where specific modes can be used, so those operating the different modes do not trample on each other’s transmissions.  These agreements are known as our band-plan gentlemen’s agreements.  They exist to help minimize interference–QRM–and to help foster good operating procedures between the different groups.

The band plans that have evolved through the decades are not regulations, and do not mean that any particular group of amateur radio operators own any frequency or subband.  A mode does not own a particular subband.  Amateur radio operators are not encouraged to start transmitting a mode that is typically found in that subband, if someone else is on that frequency using a mode not expected.

Just because some other operator is using the subband for a mode not in compliance with the gentlemen’s agreement, don’t purposefully try to eject that operator.  At the same time, the gentlemen’s agreements exist to help amateurs avoid interference with others that are using different modes.  Thus, the operator who has chosen to use a non-standard mode for a subband known to be used for some other mode should move that operation to the subband identified to be for that operator’s current mode of transmitter emissions.  In other words, do not QRM another amateur radio operator, and do not cause confusion and frustration by barging into a subband for a mode that you are not intending to use.  Use the mode expected in the subband of your current operations.

This concept is especially helpful when we consider weak-signal operations.  If a very strong, loud teletype transmission begins in a subband that is set aside for weak-signal propagation modes like WSPR, then it defeats the efforts of the operators making the attempt to have successful weak-signal two-way communications.  Thus, the teletype transmission should be made in a subband where teletype operation is expected and acceptable.  And, WSPR should stay in the subband where people expect to find WSPR signals.

This concept is also applied to VHF or higher bands.  Why?  If repeaters are parked on known repeater subbands, then weak-signal single-sideband communications can take place in a subband where repeaters are not allowed.  By allowed, though, I mean, by agreement with gentlemen’s agreements.  Regulators have stayed out of the amateur radio operations except by creating regulations at a high-level–for instance, the FCC stipulating that voice communications are not allowed between 14.000 MHz and 14.150 MHz, in the 20-Meter band.

The Frequency Grabs by the WSJT Developers, Planners, and Leadership

With several current release candidates of the WSJT-X software by Joe Taylor, the group of developers and leadership have programmed into the WSJT-X software a set of NEW default frequencies.  These new frequencies are in addition to their current pre-programmed frequencies that the amateur community now identifies as, The FT8 Subbands.

The new proposed frequencies are right on top of other subbands where other modes have been operating for decades (such as PSK and Olivia, and many others).  There was no community discussion, except within the WSJT community.  And, when someone protested the take-over of other well-established subbands, those protests were shot down.  The stated reasons included, “Well, those other modes are not very active or popular, because spots are not showing up on various spotting networks.”  Such reasons break down on deeper consideration–for instance, most spotting networks are not programmed to automatically identify Olivia transmissions.  CW, PSK, and FT8 are programmed into scanners, but other modes are ignored.

This behavior, considered rude, arrogant, presumptuous, and anti-gentlemanly (referring to well-established gentlemen’s agreements) has happened before, with the initial release of FT8.  They (the WSJT-X developers and leadership) simply picked a frequency slice of each subband, without true collaboration with the wider amateur radio community.

When this columnist and fellow amateur radio community member, attempted a discussion, the retort from an official representative was an absolute dismissal of any protest against the choice and method of frequency options within the WSJT software. While the software marks these frequency as suggestions, only, these defaults are used without question by the operators of said software.  And, the mode is so fast that there’s no human way of truly monitoring the frequency before use, to see if some other mode is in operation.  Besides, weak-signals that are present but cannot be heard by one’s ear, might well be in operation.  Subbands exist to keep QRM from covering up the weak signals of the mode expected at that frequency.

Enter the IARU…

The IARU has decided to step in and join the discussion.  “The International Amateur Radio Union has been the worldwide voice of radio amateurs, securing and safeguarding the amateur radio spectrum since 1925.”  The IARU guides regulating bodies like the FCC, regarding the administration and rule-making pertaining to amateur radio.

The IARU states, on their website,

The radio spectrum is a priceless natural resource. Because radio waves do not respect borders, the use of the spectrum must be regulated internationally. This is accomplished through the International Telecommunication Union (ITU), a specialized agency of the United Nations. Through World Radiocommunication Conferences (WRCs) held approximately every four years the ITU revises the international Radio Regulations which have the force and effect of a treaty. The Radio Regulations allocate the spectrum to different radiocommunication services such as broadcasting, mobile, radar, and radionavigation (GPS). The most recent WRC was held in October-November 2019. The next one is not yet scheduled but is expected to be held in 2023, so it is usually referred to as WRC-23.

New uses of the spectrum are being developed every day. This puts enormous pressure on incumbent users who are called upon to share their spectrum access with new arrivals. The allocation process is extremely complex, especially when satellite services are involved.

Reportedly, from first-hand communication from one IARU representative,

WSJT-X RC3 has 14074 kHz again for FT8. IARU is intervening. Stay tuned. I am asking for further suggestions.

IARU R1 HF Manager

This is very welcomed news!

What ought to take place, as quickly as possible, is to rally the different interested parties, like the Olivia group, the PSK groups, the various CW groups like CWOps, FISTS, and the SKCC, and many others, for ideas and suggestions.  A discussion must take place in the hope that new gentlemen’s agreements can be made, that include the FT8 and FT4 operations, without stepping on the subbands of other digital modes.

As Tom says, STAY TUNED.

If you have suggestions, please comment. This columnist will summarize the main ideas of the comments and forward them to Tom.  You may also contact the IARU managers and let them know your suggestions.

Discussions in the Olivia community are ongoing, too.  Join in at OliviaDigitalMode.net even if you are not yet an Olivia operator.

On Facebook, you may also discuss your thoughts, in either the Olivia Digital Modes on HF group or in the Digital Modes on HF group.

If you use FT8 and FT4, voice your concerns and ideas, too.  Open dialog, without declaring war, is welcomed and hopefully will prove productive.

This article is the first in a series focusing on band plans, and gentlemen’s agreements. Please stay tuned for more installments.
