Let’s get creative this year on Field Day
By Dan Romanchik, KB6NU
Since many of us are still hunkering down, and that doesn’t look like it’s going to change much by the end of June, Field Day is going to be a lot different this year. Our club has cancelled our club event, and I’m really going to miss helping newcomers operate the GOTA station, the food, and all the camaraderie. That doesn’t mean that Field Day can’t still be fun, though. Let’s’ get creative!
First, note that the ARRL has modified the Field Day rules for this year. The biggest change is that Class D stations, that is home stations using commercial power, can now work other Class D stations for points. Previously, this wasn’t allowed.
The second change is that the ARRL will publish aggregate club scores this year. In previous years, this was only done for Class A and Class F entries. Remember, though, Field Day isn’t a contest (yeah, right!).
Personally, I plan to operate 1B-Battery. I’m going to set up my KX3 on the front deck and power it with a LiFePo battery charged by a recently-acquired solar panel to get the 100 point bonus for alternate power. For an antenna, I plan to set up my 20m/40m fan inverted-V “GOTA antenna” in the front yard.
I’m going to shoot for other bonus points, too:
- copy the bulletin—no brainer.
- promote my location on social media—I am going to get on NextDoor and invite neighbors over to watch from an acceptable “social distance.”
- put some literature down at the bottom of the hill near the street and claim a public information table.
- send a press release to the local online paper and claim a media publicity credit.
- perhaps get someone under 20 to come and operate while I coach from an acceptable “social distance.”
If Class B isn’t your cup of tea, check out the presentation, “Field Day and Social Distancing,” http://tiny.cc/fdsd by Anthony, K8ZT. It has a lot of great ideas, including ideas on how to operate mobile (Class C).
Field Day doesn’t have to be a downer this year. Get creative and have some fun.

SCCARC May meeting recap with W6JIM
Our guest speaker was Jim Crites (W6JIM). Using a PowerPoint that detailed many interesting facts about the Long Island CW Club. This PowerPoint program was recently used on Ham Nation.
He demonstrated the free CW computer program he uses to teach CW, talk about other free classes his Club offers, and end with their website and how to join.
Jim showed these things by sharing his screen with our group.
Here is Jim’s Bio:
W6JIM, Jim Crites
CW Instructor, Long Island CW Club
Home Town: Walnut Creek, CA
Retired USAF after serving over 30 yrs.
“Hello, I joined the Long Island CW Club in February 2019 in order to improve my own CW. I was invited to teach for them 6-months later in August. I teach Beginner-1 and Intermediate classes.
In Beginner-1 I introduce the first 20 characters. My Intermediate class teaches the back-and-forth protocol used in a CW QSO. I have taught over 80 students through 6-classes and have just started a new class of 26 students.I love CW and enjoy talking about it! I look forward to meeting you soon to discuss the Long Island CW Club.”

Operating Practices on Field Day
There was a request at the last Field Day planning meeting for some videos on how to operate on Field Day. Here are some links of some good practices and some bad practices. You should be able to discern the difference! If anyone knows of some other videos pleas add to the list. I have seen a video of a really sharp operator who was smooth, in control, and racking up the points, but I couldn’t find it. Let’s put together a virtual Field Day training session here.

Club Meetings On the Air
Last week’s meeting on the air on K6BJ-2m went well. We will continue to hold meetings this way during mandated social distancing requirements.
Field Day 2020
The combined Santa Cruz and SLV clubs’ Field Day Committee consists of Scott, KE6QZJ; Richard, K8SQB; Gary, K6PDL; Sam, WB6RJH; Kerry, K3RRY; Karen, KM6SV; and Becky,KI6TKB. The committee continues to discuss the shape of the event, given social distancing requirements. There will be no pot luck, and so no club expenses for food. The SLV Club is
willing to pay for a PortaPotty this year only. Ideas for public outreach via video were discussed.
An update from the Field Day Committee is expected next month.
Club Repeater Shack Door
Site assessment by Becky and Duane, K6TS, still to be scheduled.
Club Station Shack Roof
No further actions needed.
Club Repeater Status Update (Nate)
No new problems were reported in the last month, so Nate has not visited the site. The quality of audio on link to KJ6FFP/W varies.
Summary of proposed Equipment upgrades to K6BJ 2 meter repeater

Call to order
A meeting of SCCARC (Santa Cruz County Amateur Radio Club) was held via telephone conference call on March 26, 2020, beginning at 7:35 PM.
Attendees: Allen, WB6RWU; David, N6DTA; John, N6QX; Becky, KI6TKB; Nate, KM6THA; Cap, KE6AFE; Richard, K8SQB; Don, K6GHA
Board Members not in attendance
Not in attendance: none
Approval of minutes
February BOD meeting minutes approved.
All good – current balance about $4,000.
P.O. Box renewed for another year.
John was reimbursed $200 for the club’s liability insurance.
Renewal of club incorporation with California Sec’y of State due in April – no cost.
Club Repeater Shack Door
Becky found a replacement metal exterior door available at Home Depot for $187 plus tax. The Board elected to defer any purchase until there was a plan for installation. Is the door frame out of square? To assess, Becky volunteered to visit the site with Duane, K6TS, or another volunteer
with carpentry experience.
Club Station Shack Roof
Allen and Cap assessed. Roof’s overall condition seems satisfactory. $400 quoted for whole-roof sealant, but this may be inappropriate. Spot-patching of holes likely would be better. Cap will inspect after Thursday’s heavy rain to locate any leaks.
Club Repeater Status Update (Nate)
Nate and Paul, K6EH, spent considerable time on Sunday, March 1, adjusting levels to improve the audio quality on several circuit paths. The audio level on the UHF link from Watsonville varies unpredictably, perhaps a thermal issue in the link receiver. The 1‐second audio delay when
keying the repeater is due to the Yaesu interface and not adjustable.
Everything is currently functioning. The CAT-1000 controller intermittently fails to decode DTMF tones, an internal problem.
The separate K6BJ UHF repeater outputs no PL tone when repeating a digital audio signal. No fix for this. In the future, Nate plans to repurpose the PC, which Cap donated to the club repeater, to enable Wires-X on the UHF repeater.
Club Repeater Equipment Upgrade
The board was divided on the question of significant expenditures to upgrade some of the repeater gear. Becky asked Nate and David to create a summary of the current repeater status and recommendations for replacement equipment, intended for posting in a separate chat room on the club email reflector in order to get member input.
Field Day 2020
The combined Santa Cruz and SLV clubs’ Field Day Committee consists of Scott, KE6QZJ; Richard, K8SQB; Gary, K6PDL; Sam, WB6RJH; Kerry, K3RRY; and Becky, KI6TKB. The committee currently favors space at a winery at 25200 Loma Prieta Avenue, in the Santa Cruz Mountains. This remote location lacks restrooms, and so would require porta-potty rental, about
$450, a new expense for Field Day. Alternatively, operation might be possible at Sky Park, a more accessible spot. It remains to be decided whether the club will pay for food, or whether to go 100% pot-luck. Committee recommendations expected next month.
Club Name Badges
Don has ordered magnetic badges from Name Badges International for new members at a cost of
$10.55/badge. The Board approved reimbursing Don $68.39 for the order.
Topics of Interest On-Line Poll Results
David got input from 11 responders in his poll of topics for future club meetings. Ordered by
number of requests:
1) Software-Defined Radios
2) Antenna Building; Digital Modes
3) Fox Hunting; DX and Contesting; Portable Gear and Operating Techniques
4) License Upgrades to General or Extra Class
5) Compromise Antennas for Small Spaces
6) Ham Radio Baloon Tracking
David reported we now have 99 members in our Groups I/O, with 99 posts in the month of
Meeting adjourned at 9:03 PM.

A modest proposal (for the next Extra Class question pool)
By Dan Romanchik, KB6NU
At our last club meeting, I was discussing the changes to the Extra Class question pool with someone, and the topic of memorizing the answers popped up. As I always do, I mentioned that many of the questions you can only get right by memorizing the answer. At that point, someone down the way piped up. “Not me,” he said, “I studied the material so that I didn’t have to memorize the answers.”
At that point, the president called the meeting to order, so I didn’t get to challenge him on that point, but that statement is just plain wrong. First of all, it’s true that some questions you can only get right by memorizing the answer. Almost all of the rules questions are that way, for example.
Secondly, there is no way to study the rest of the material in any depth and still have time to actually be an amateur radio operator. The amount of material that the Extra Class question pool covers takes an electrical engineering student four years or more to study thoroughly. And even then, some topics are bound to get short shrift.
So, we’re back to memorizing. I would say that even an “engaged” person will memorize about half the answers. I’d go even further and say that those that “study” the technical topics, don’t study it as thoroughly as a college student would.
For example, there are a dozen questions in Section E7G – Active filters and op-amp circuits: active audio filters; characteristics; basic circuit design; operational amplifiers. Despite the name, you don’t need to know how to design or build an op-amp filter. All you really need to know is that op-amps are high gain devices and if you have a circuit like the one shown below, Vout/Vin = RF/R1.
These concepts are relatively easy to learn. but there are also two questions on filter “ringing.” Honestly, you’re better off just memorizing the answers to those questions unless you have a real interest in active filters that use op amps. Wading into the mathematics isn’t all that hard, but when you consider this is only one of dozens of topics, you can see where doing any kind of in-depth study is going to take you months, if not years, to accomplish.
A modest proposal
The end result of this approach to testing is that we have many Extra Class licensees who know about a lot of things, but not in very much depth. Perhaps that’s OK. Perhaps that’s just what the question pool committee of the National Council of Volunteer Examiner Coordinators (NCVEC) was shooting for. If, however, we want an Extra Class license to denote that the licensee has some real technical expertise, I have a modest proposal.
Basically, my idea is that instead of testing on an incredibly wide range of topics, we test applicants on a set of basics, plus one or two particular topics. These would be topics that the person has expertise in already or enough of an interest in to study the topic in some depth.
Below are the topics that I would consider to be basic and some that I consider to be more specialized. This is, of course, not an extensive list.
- Basic questions (20 questions, everyone takes this part of the exam)
- Rules and regulations
- Electrical principles/basic circuits
- Technical Interests (Choose two, 20 questions each)
- Antennas and transmission lines
- Radio wave propagation
- Analog and digital design
- Digital communications and networking
- Software/software-defined radio
- Operating: contests, DXing, direction finding, etc.
The questions in each of the technical interest question pools would be designed to really test the knowledge of the person taking the test. We’d have to figure out a way to make them difficult enough so that one couldn’t just simply memorize the answer. Questions could appear in one or more technical interest test. For example, a question on VHF/UHF propagation could appear in both the Radio Wave Propagation and VHF/UHF question pools.
Having said all this, I realize that this would not be easy to implement. You’d have to first decide on the topics and then enlist experts for each of the topics and get them to come up with a list of 80 – 100 questions each.
I realize that this has very little chance of being adopted, but it’s interesting to think about, no? And, we have four years to do this, so it could be possible.

How the National Bureau of Standards helped make “radio”
This was originally published as “NIST’s Role in the Early Decades of Radio (1911-1933)” on the National Institute of Science and Technology’s blog, Taking Measure…….Dan
Even if you weren’t able to watch the recent Super Bowl on TV, you could still listen to the play-by-play commentary on the radio. But radio does more than just broadcasting sporting events or playing music. It plays a major role in emergency response, navigation and science.
The word “radio,” however, didn’t become part of our regular vocabulary until 1911, and it happened thanks in part to J. Howard Dellinger, a radio scientist at the National Bureau of Standards (NBS), the agency that became the National Institute of Standards and Technology (NIST). This came about when the second International Radiotelegraph Conference was being planned in London, and a professor sent Dellinger a paper that he was going to present to the conference for review.
At the time, “wireless” was used as the term for radio communication, especially by the British. However, NIST was charged with revising standards in preparation for the conference, and Dellinger suggested that the professor use “radio,” which was already becoming a popular word in the U.S., instead of “wireless.” The professor agreed, and the word “radio” went on to become the universally accepted term.
Dellinger not only played a role in popularizing the word “radio,” but he also played a role in the first radio work done at NIST. A commercial company asked NIST to calibrate a wavemeter, a device developed by one of its engineers that measures electromagnetic waves like those of radio. Dellinger was known as the wireless expert and took on the project of calibrating the first radio instrument at NIST.
A New Type of Radio Receiver
But for radio to become mainstream, it first had to be commercialized, which began with its introduction into households. However, the challenge was building a radio set that used the electrical current, called alternating current (AC), which powered lights, fans and kitchen appliances when plugged into wall sockets. The predecessor to this technology was developed and patented by two researchers, Percival D. Lowell and Francis W. Dunmore, at NBS in 1922. They called their invention the “mousetrap.”
The “mousetrap” was a receiver for a radio amplifier that could run on AC. This was considered a breakthrough because at that time radios were only able to be powered by direct current (DC) provided by batteries. These batteries were bulky and heavy, had to be charged from time to time and were considered dangerous because of the acid used in them. The researchers’ prototype meant the radio could be used in homes without causing damage and with the same performance quality.
Lowell and Dunmore filed two more patents together for other innovations, and for the “mousetrap” they sold the rights to the Dubilier Condenser Corporation. Little did they know that, because there was no uniform policy on patents issued to government employees, their actions would result in more than a decade of litigation over who legally had the rights to the patent.
While they were tied up in court, the Radio Corporation of America (RCA) developed its own model of the AC radio in 1926. Its model later became the first AC-powered radio sold to consumers.
Flying by Radio
During the early years of flight navigation, NIST was doing research to assist pilots while they were flying and landing. Pilots needed three things to get their bearings when flying “blind,” meaning it’s foggy, too dark or too cloudy to see. They needed to know the longitudinal position, altitude and speed of the aircraft, which were all achieved by various beacons installed in the plane. The remaining issue was that there were two frequencies the pilot constantly had to switch between the frequency that the Department of Commerce used to send weather information to planes and ships, which sometimes caused interference for pilots, and the frequency the radio beacon operated on, which gave altitude and other information.
Dunmore created a prototype, but Harry Diamond, a radio engineer who joined NIST in 1927, completed the device, called the radio guidance system. Diamond solved the problem by developing a separate device that allowed for voice communication to the pilot without receiving any outside interference from ships’ radios.
A Curtiss Fledgling, a trainer aircraft developed for the U.S. Navy, was equipped with the device, and flight tests were performed between NIST’s experimental air station at College Park, Maryland, and Newark Airport in New Jersey in foggy weather. After a series of successful tests were performed, the device was turned over to be used by the Department of Commerce in 1933.
Praise From a Famous Inventor
While mostly intended for serious users, some of NIST’s journals and publications were popular with the public. One such book, titled The Principles Underlying Radio Communication, covered topics such as elementary electricity, radio circuits and electromagnetic waves and was also published as a textbook for soldiers in the U.S. Army. The famous inventor Thomas Edison received a copy from NIST and wrote a letter thanking the first director, Samuel W. Stratton, for publishing it, saying it was “the greatest book on this subject that I have ever read.”
As these and other examples show, NIST had a significant influence on radio research between 1911 and 1933. However, NIST’s radio work didn’t end with the first blind landing. NIST would continue to contribute to the field leading up to and during World War II, and research continues to this day in areas such as 5G, public safety communications and spectrum sharing.
