Our April meeting featured Andy Keels, KD4ABB. His presentation was titled "Stealth Antennas". It was excellent. -Do you live in a subdivision or condominium where your HOA doesn't allow antennas to be erected? Do you live with someone who doesn't appreciate the aesthetic value of antennas like we do? Do you operate in parks or other places outdoors where antennas are discouraged?
If so, our April program will be just what you're looking for.
Andy Keels, PE, KD4ABB will be talking about Stealth Antennas, antennas designed to work well but be unnoticed. The PE after Andy's name indicates that he's a registered professional engineer so we can be assured he knows what he's talking about.
Satellite TV antenna bans were preempted in 1996 but there are no such protections for amateur radio antennas.
The ARRL has been trying for 10+ years to get federal legislation passed, but they have been unsuccessful.

Amateur Radio Astronomy
Tom Crowley, KT4XN
Date: Thursday, March 3, 2022    Time: 7:00 PM ET    Location:  ZOOM Videoconference
Video: https://youtu.be/FImfEKqcyXw​
Slides:: Forthcoming
Our March meeting featured Tom Crowley, KT4XN, who delivered a fascinating presentation on Amateur Radio Astronomy.
Our universe radiates electromagnetic waves all over the spectrum from DC to x-rays. When we look at the sky, we see only the visible light portion of the spectrum. And much of that visible light is attenuated by the atmosphere. But when we listen to the incoming radio waves, we get a much bigger and more detailed "picture" of the universe.
The science of receiving and interpreting the radio waves is called Radio Astronomy.  It can be done by professionals and by amateurs.
Tom first outlined the spectrum of the incoming waves , then he discussed the methods we use to receive them. During that discussion, he showed us pictures of some of the larger radio telescopes and then went on to explain what we learn from listening. Finally, he discussed ways that we can listen to the universe on our own.
The presentation was quite enlightening.

SDR (Software Defined Radio)
Ria Jairam, N2RJ
Date: Thursday, February 3, 2022    Time: 7:00 PM ET    Location:  ZOOM Videoconference
Video: https://youtu.be/rxmi1HBiY38​
Slides:: Download
Our February meeting featured Ria Jairam, N2RJ, who spoke about Software Defined Radio (SDR). Ria explained that SDR is a marriage between radio hardware and computers.
Conventional analog radios use hardware to convert the RF received from the antenna to the audio we hear over the speaker on the transmit side, and from the audio picked up by the microphone to RF we shoot into the antenna on the transmit side.
SDR radios convert the RF received from the antenna to a digital signal that is passed to a computer, which performs all of the demodulation and filtering functions that the hardware did in the analog radio, then converts it back to audio to feed into the speaker. On the transmit side, the analog signal from the microphone is converted to a digital signal that is passed to a computer. The computer filters and modulates the signal then passes the digital signal to a converter to convert it to analog. The analog signal is fed into the antenna.
Ria showed us diagrams of the major components of SDR radios and discussed the function of each one. That was very helpful. She went on to describe the advantages of SDR over analog radios and talked about the various SDR radios on the market. She showed us where we could find comparisons of the radios. The SDR radios range in price from about $600 to about $6,000 so the comparison numbers are very important. There are also some entry level SDRs available for under $100. They are receive-only. Low end transmit/receive SDRs fall into the $100-$600 range.


Ria Jairam, N2RJ is the ARRL Hudson Division Director. She has been licensed since 1997 in Trinidad and Tobago and in the US since 2001. She first became interested in radio at 5 years old from her dad, an avid SWL and learned about amateur radio from a teacher, Mr. Tony Lee-Mack, 9Y4AL. Ria is active in contesting, Dxing, DMR, DSTAR and digital modes. To her name are several DX and contest awards including 9 band DXCC (160 through 10 meters), Challenge at the 1800+ level, all 3 modes and 325 entities mixed. She has also won several contest plaques including regional, national and North American titles in various DX contests. Ria has won a “Top Elmer” award in 2016 for her mentoring on the Flex Radio forums and also helping users use their radios remotely. She subsequently was awarded two “Top Tester” awards in 2017. She is a volunteer QSL card sorter with the W2 QSL bureau, run by the North Jersey DX Association (NJDXA) and is the Northern NJ section manager for the Frankford Radio Club (FRC). She is also the District 2 chair of the Young Ladies Radio League (YLRL) and a member of the British Young Ladies Amateur Radio Association (BYLARA). Ria is an alumna of the NYU Tandon School of Engineering, where she studied Electrical Engineering. In the ARRL, Ria is currently a member of the Administration and Finance committee (IT falls under this committee) and the Band Planning committee. Look for her in the DX pileups, often operating remotely, or operating WSJT digital modes to snag a new one.

Antennas, HOAs and the ARRL
Fred Hopengarten, Esq., K1VR, Director of ARRL's New England Division

Date: Thursday, November 4, 2021    Time: 7:00 PM ET    Location:  ZOOM Videoconference
Video: https://youtu.be/dswWBUpqm5Q

We had two presentations this month. ARC Meeting November 2021. Eddie Leighton, ZS6BNE presented from South Africa on RaDAR, Rapid Deployment of Amateur Radio. It's a biannual operating event where hams deploy in a park, mountain summit or other outdoor location, operate, pack up and move to another location that's at least 6km away. They set up there, operate and pack up and move again.. It's a 4 hour event where hams operate from as many locations as they can.

Eddie also talked about RaDAR Sport, a variation on RaDAR where points are awarded for operation over 24 hour periods. RaDAR uses a novel central logging system where all participants record their contacts in an online log that accessible to all authorized users.

The main presentation was not recorded at the request of the speakers. They said that they were prepared to give us a thorough walkthrough of the problem, their opinions and some details on what the ARRL is planning to do. Many of the details are non-public so the speakers gave us a choice of recording the presentation and getting only general, publicly announced information or not recording the presentation and hearing the good stuff.

The ARC Board chose this option.

Here's a general summary.

The main presentation was on Antennas, HOAs and the ARRL and was presented by two ARRL Directors and Board members: Fred Hopengarten, Esq., K1VR, Director of ARRL's New England Division and Mickey Baker, N4MB, Director of ARRL's Southeastern Division. Georgia is in this division.
In the U.S., municipalities, such as cities, counties and states set limits on the the size and location of outdoor antennas. In many private developments of houses and/or or condos, the Homeowner's Associations (HOA) of Condo Associations also set placement rules. These rules often prohibit hams from putting up any outside antennas or, if outside antennas are allowed, there are severe size and siting restrictions.
In 1985, the FCC issued a Memorandum Opinion and Order (PRB-1) preventing municipalities from prohibiting the erection of amateur radio antennas. That language was subsequently incorporated in the FCC Rules in section Part 47 §97.15 (b) of the Code of Federal Regulations (CFR). In 1996, Congress ordered the FCC to issue regulations overturning HOA restrictions on the erection of TV antennas, direct broadcast (satellite) antennas and wireless internet (WISP) antennas. The FCC codified these rules in Part 47 section §1.4000 of the CFR. The ARRL tried but failed in the early 2000s to get the FCC to extend the same rights residents had to erect TV antennas and satellite antennas to ham radio antennas.

Efforts continued over the next 20 years, culminating in the passage of the ARRL-written Amateur Radio Parity Act (H.R. 555) by the U.S. House in the 115th Congress on 2017. But it never made it through the Senate. The ARRL subsequently tried and failed to get the FCC to adopt the language of this act without being ordered to by Congress.

Our speakers updated us on the issues in general and, specifically, what the ARRL is doing now to get us the relief from the restrictions that we seek, In short, the ARRL is crafting new legislation and working with potential sponsors in the House and Senate to introduce the bill when the ARRL is ready. The speakers outlined several concerns about the Parity act as written, told us how the new bill differed and gave us their opinions and estimates of success of the current efforts.

This presentation was not recorded because a lot of what we were told was for background use only and not for publication. We had a frank discussion.

Slides (from Mel's presentation to Ham University:  HERE
Video: https://youtu.be/_y63JIT5eCk

Our October (7th) program featured Mel Granick, KS2G, who presented on HF operations.  Here's the announcement:
Do you have a Technician’s license and::
  • You're curious about operating HF or
  • You want to know more about HF before talking the General exam
If so, this meeting is for you. Mel will give us an overview of many of the facets of operating HF, including:
  • The pros and cons of each of the major HF bands
  • Propagation. How does the HF signal travel so far? How does the weather in space affect the different bands? 
  • What do you say when you’re on the air? 
  • How to operate your HF radio. Which buttons and knobs do you use for transmitting? Receiving?
Are you a General or Extra?  Do you remember your first HF contact? I remember mine and it wasn’t pleasant. I thought I knew what to say. I didn’t. I thought I knew about a feature on my radio that’s common to just about every radio made in the past 20 years. I didn’t.
I could have used a presentation like this one before getting on the air. I’m actually looking forward to it now.
You can rest assured that there will be plenty of time at the end of the presentation to get any questions you have about these topics or any others answered.

​Carl Luetzelschwab, K9LA
  presented on "The Sun, the Ionosphere, Space Weather and Cycle 25".
Carl briefly reviewed solar issues and then tied space weather to propagation. Then he discussed the predictions for Solar Cycle 25, the 11 year sun cycle that started in December 2019, and its current status.
Sun spot predictions are of interest to commercial broadcasters, communications companies and amateur radio operators because of the correlation between sun spots and solar activity, such as solar wind and coronal mass ejections (CME). Those events can alter atmospheric propagation on earth and result in radio signals taking unpredictable paths. Commercial broadcasters and communications companies don't like it when that happens. Hams, on the other hand, are thrilled.

 Adventures in FT8 and FT4
Frank O'Donnell, K6FOD
Date: Thursday, August 5, 2021    Time: 7:00 PM ET    Location:  ZOOM Videoconference
Slides: PDF​
​Video: https://youtu.be/GwGrvAuhyL0
Frank O'Donnell, K6FOD presented on FT8 and FT4.  These are digital modes, primarily used on the HF bands,  for making local and distant contacts. The QSO's are structured in a particular way, which Frank detailed, and take less than 3 minutes.
Unlike more traditional modes of ham radio, digital modes require a computer to be used that is interfaced to the radio. The computer produces a digital data stream that is converted to tones that are sent to the radio for transmission. On the receive side, the audio is passed to the computer where the individual FT8 transmissions are broken out and displayed on the screen.
Frank talked about WSJT-X, the program used to send and receive FT8. It runs on Macs, PCs and Linux systems. He also mentioned the PSKReporter website and the JTAlert app.
He told us that FT4 was a faster FT8 because transmissions were only 7.5 seconds instead of 15.
Overall, it was a fascinating and well-received presentation.
Bio
In recent years the FT8 digital mode has been taking the ham world by storm, becoming the most popular mode on the air according to statistics from the ClubLog.org website. If you’ve been thinking of giving FT8 a try but are wondering where to start, ARC’s August 5 online presentation by Frank O’Donnell, K6FOD is one you won’t want to miss.
After earning his ham license three years ago, within nine months Frank earned the ARRL's DXCC award for verifying contacts with 100 countries — all on FT8. In 2019, he received the Southern California DX Club’s Clipperton Award for newcomer of the year.
Topics Frank will cover in his talk include an overview of how FT8 works, setup for Windows, Mac, and Linux systems, a basic FT8 QSO, “fox and hound” mode for DXpeditions, and the new FT4 variant for contesting.
We will take Q&A after the presentation.
Frank took up ham radio after retiring from a 32-year career in public affairs at NASA’s  Jet Propulsion Laboratory. While at JPL he led the press office for more than a decade, directing newsrooms for missions including Galileo to Jupiter, Cassini to Saturn, the Mars Pathfinder lander and Sojourner rover, the Spitzer Space Telescope, and numerous Earth science missions. In addition to HF DXing, he also participates in the ARRL’s twice-yearly Frequency Measurement Tests, determining frequencies of signals received from thousands of miles away to within as little as a couple of hundredths of a Hertz.
​He and his family live in Southern California.

Everything You Need to Know About USB and Serial Interfaces
Bob Wilson, N6TV
Date: Thursday, July 1, 2021    Time: 7:00 PM ET    Location:  ZOOM Videoconference
Slides: PDF
​Video: https://youtu.be/UB8lFM6gC7c​
Bob Wilson, N6TV, presented the program "Everything You Need to Know About USB and Serial Interfaces".
Topics discussed were:
⚫ Legacy PC Serial Ports
⚫ USB Ports and Devices
⚫ USB-to-Serial Adapters
⚫ Using the Device Manager
⚫ Managing Serial Port Numbers
⚫ Using Serial Ports for CW / FSK / PTT Keying
⚫ Sharing Serial Ports
⚫ USB Sound Cards
⚫ Q & A
Bob first talked about serial ports, from their first appearance on PC's as 25 pin and 9 pin "D" shell ports to modern USB ports. He showed a picture of USB A and B connectors. They each come in fast (USB 2.0) versions, which have black inserts, and super speed (USB 3.0),  which have blue inserts.

Radios have serial ports but computers have USB ports. The ham radio software on the PCs is written to talk to serial ports so a converter cable is needed. It connects to the radio with a serial connector and connects to the PC using USB. Through a combination of hardware and software, the cable emulates a serial device so it works with the ham radio software.
Bob detailed how Windows recognizes the cable, what configuration changes users should make to improve operations and what to do if Windows fails to recognize the cable.
Lastly, he talked about the appropriate settings for the most popular radios.
A lively Q&A followed, which was quite educational.
Bob was a really good sport. He said that our people could email him at [email protected] If they still had questions or problems. That was a priceless offer.

Dr. John Kludt, K7SYS presented the program "ARISS Update and Into the Future".
We learned a lot from John, who is Director of Operations of ARISS (Amateur Radio on the ISS organization). ARISS works with NASA to keep an amateur radio presence on the ISS so they can arrange for students to talk to astronauts on the ISS via ham radio. Both NASA and Roscosmos, the Russian version of NASA,  require their astronauts to have amateur radio licenses. They each speak to about 20 groups of students a year in their countries, primarily at their schools.
John detailed the history of amateur radios on the ISS. Amateur radios have been on the ISS since its early days. In fact, amateur radio is the longest continuously running experiment on the ISS.
When astronauts aren’t using the radios, the radios are in repeater mode so they can be used for long distance communication by hams on the ground, just like other satellites.
John showed us a picture of the inside of the ISS.  It was hard to spot the ham radio in the picture but it was there. He also discussed the antenna configuration and showed pictures of astronauts installing an antenna during an EVA.
ARRIS works with the radio manufactures — primarily JVCKenwood — as well as designing their own space-certified equipment for the station. New radios were recently installed in the station. John elaborated on them, as well as the plans for future radios.
There’s a lot going on up there. John asked us to donate to ARISS to support their work and help keep them going.
We had time at the end of his presentation so John gave us an overview of the 40 amateur radio satellites in orbit. NASA has plans to put a new  satellite in orbit around the moon within the next few years. In addition to the scientific instruments, there'll be an amateur radio repeater aboard which will allow contacts between hams with simultaneous views of the moon.
Summary: Amateur radio in space is alive and thriving.
John’s slides are online. See above.

Marcel Strieber, AI6MS presented the program "Everything you need to know about Lithium Batteries"
Batteries are a necessity for almost all portable radio operations. With the advent of modern battery chemistries, the choices available to the radio amateur are plentiful. This presentation focussed on the three common battery types: Lead-Acid (SLA/AGM), Lithium (Lion/Lipo), and Lithium Iron Phosphate (LFP/LiFePO4). We discussed the pros and cons of each chemistry, common uses and misuses, and everyday application tips for our latest amateur radio projects.
​We now know everything we need to know about batteries.

The Georgia QSO Party; NanoVNA
 Lee Johnson, N4WYE (NanoVNA) and Jeff Clarke, KU8E (Georgia QSO Party)
Date: Thursday, April 1, 2021    Time: 7:00 PM ET    Location:  ZOOM Videoconference

We had two excellent speakers at our April meeting.
First,  Jeff Clarke, KU8E, told us all about the 61st Annual Georgia QSO Party (GQP), which will be held in two weeks (April 10-11, 2021) It's an annual competition where amateurs outside of Georgia attempt to make as many contacts with amateurs in Georgia as they can. This will make Georgia amateurs pretty popular that weekend so we will we able to make lots of contacts.  Jeff mentioned that the QGP website URL had changed since last year. The new GQP URL is http://gaqsoparty.com.
Jeff went over the rules for Georgia Stations and non-Georgia Stations. All stations get one point for each SSB contact and two points for each CW contact. Georgia stations multiply their number of contacts by the number of unique US States (0-51 (DC counts, too)) + Canadian Provinces (0-13). Non-Georgia stations multiply their number of contacts by the number of unique Georgia counties (0-159) that they talk to. People in Georgia can get in their cars and operate from as many counties as they can. Awards are given to individuals and clubs who get the most points in 37 categories. The ARC sponsors the award for the Georgia Club with the highest score.
More details can be found on the GQP website and in the video of the meeting, which will be posted to YouTube shortly.
If you missed any of this presentation or you would like to hear it again, tune in to the Southeast Contest Club's zoom meeting on Monday, April 6, 2021 at 7:30 p.m. ET.
​
The ARC will hold an outdoor event so we can participate in the GQP. 
Our main speaker, Lee Johnson, N4WYE, gave an excellent presentation on the NanoVNA Vector Network Analyzer.
He explained the functions of the NanoVNA. In addition to measuring SWR and reflected power, it can locate breaks in cables, generate Smith Charts, measure the transmit pattern for an antenna, find its nulls, measure the velocity factor (VF) of a feedline and antenna, test filters and much more. For $50, it will give the amateur the equivalent of a $50,000 professional analyzer. Lee showed diagrams of the internal structure of the NanaVNA and he showed videos of the operation of the NanoVNA in several scenarios. 
The ARC will be using a NanoVNA at the GQP event in 2 weeks to measure the performance of antennas we'll be stringing up in the trees at the park.
Lee said he'd be available via email if anyone needed NanoVNA help in the future. [email protected] . Thanks, Lee. He also provided a slide of resources for further NanoVNA education.
And he recommended reading the "Absolute Beginner's Guide to the NanoVNA". It can be found here..

DECEMBER 2020

ARC Show 'n Tell and Shack Photos
Various ARC members and meeting participants
Date: Thursday, December 3, 2020    Time: 7:00 PM ET    Location:  ZOOM Videoconference
Video: https://youtu.be/5swWBMkfSpU
At our December meeting, we had a show and tell where our members showed off their shacks and current projects. 
We also had a PowerPoint presentation of all of the photos of shacks, antennas, radios and other ham related gear that our members had submitted in advance. The presentation lasted almost 10 minutes. We had a lot of pictures to show. 
And the whole thing was set to Christmas music. Thanks, everyone, for sending in your pictures.
One of our members who can't make it to our physical meetings, Dallas Jones, VK3DJ, was on the zoom...from Australia. He helped arrange for the ARC and the Geelong (Australia) Amateur Radio Club to become sister clubs. Our meeting started at 7 PM, our time, as you know, but it was 11 AM Friday where Dallas was. To him, our meetings are on the first Friday of every month.
The biggest event of the meeting was the awarding of the 2020 ARC Ham of the Year Award.
This year's recipient is Jim Reed, N4BFR. Jim is a former ARC president and he chaired the Election Committee that conducted our August election. It went smoothly and was uncontested. Jim also promoted the club on social media, explored ways of teaching hams over the internet, and helped out wherever the club needed help. He is one of our Sunday night net ops and he often steps up and runs the net when the scheduled net op can't. Jim is also an ARRL Volunteer Examiner (VE); he helped administer testing sessions where prospective hams became new hams and licensed hams upgraded their licenses.
Congratulations, Jim.
The photos were collected and made into a video by John Talipsky Jr, N3ACK

OCTOBER 2020

Sound, Ham Radio and Music
​
Bob Heil, K9EID

Date: Thursday, October 1, 2020    Time: 7:00 PM ET    Location:  ZOOM Videoconference
Video: https://youtu.be/9OPemQkmFEQ
This was a fascinating presentation by Bob Heil (https://en.wikipedia.org/wiki/Bob_Heil), K9EID, the audio pioneer and audio advisor to several well-known (from the 70s) rock bands. Not to mention that he's the founder of Heil Sound, a major manufacturer of professional and amateur radio audio products.

If you go to HRO and look at the high end microphones, you'll note that they were all manufactured by Heil. Many of us have his headsets and/or foot pedal and/or hand PTT switches.

One of the most iconic songs of the classic rock era is "Do You Feel Like We Do" by Peter Frampton
https://en.wikipedia.org/wiki/Do_You_Feel_Like_We_Do

The main reason that it's memorable is because Frampton utilized a custom device that allowed him to modulate his guitar chords with his voice, resulting in spoken words that sounded like they were coming from his guitar. That device was designed by Bob Heil. The Rock and Roll Hall of Fame recognized Heil's contribution in 2007 by inviting him to exhibit some of his historically significant devices. He was the first manufacturer ever invited to exhibit at the H of F.

Another rock legend Bob worked with is Joe Walsh, WB6ACU, of the Eagles. Yup, another ham.

​Bob's talk was all about sound and sound processing. Why are some microphones better than others? Why do musicians prefer one microphone over another? What do hams need to know about sound?
