President’s Update

Greetings RWK!

As we start 2023, I hope that you’ve noticed the great band conditions that we’ve had recently. Cycle 25 seems firmly in the upswing and early signs are that it might be better than average. As you should remember from last August’s RWK Meeting with Carl K9LA, a couple of key numbers to keep an eye on are the Solar Flux Index (SFI) which correlates to the Sun Spot Number (SSN) and the Planetary K Index (Kp). For SFI, anything over 100 is good and over 200 is usually great. For Kp, lower is better and anything less than 4 is “normal”. The graphic below was from the morning of Tuesday Jan 17th:

As one that has experienced both really good and really bad solar cycles, I want to encourage you to take advantage of this upswing in Cycle 25. The best time in the solar cycle is the upswing, and we are there! So do whatever you need to do to get back on the radio. Get a new radio! Fix that broken antenna! We are consistently experiencing world-wide activity on 10M all day, every day. It won’t last forever, please don’t miss it!

Thanks to all that came out for the 2023 RWK President’s Dinner. We had a great crowd and a good dinner and a bunch of people won door prizes. It was good to be able to see everyone and we’ve had lots of appreciative comments. See below for pictures.

As far as ham activities, we’re coming up on Winter Field Day (see below) and also the start of the 2023 hamfest season with the Cowtown Hamfest this month and Irving Hamfest in early March. We’re also planning our second annual group/team foxhunt. Hopefully there will be something to make you get out of the house!

Speaking of getting out of the house, we’re back to our regular schedule of General Meetings in February, and our program will be by Dr. Bob Heil K9EID, a legend in the audio business. He will have some tips on the best way to hook up and configure your microphone and HF radio to obtain the best possible sound and break through that pile-up!

And finally, I want to thank everyone for voting me as the 2022 recipient of the RWK Warren Bruene Award. The club takes the award very seriously and I’m proud to be another in a growing list of hams that have made RWK what it has become – one of the biggest and best radio clubs in Texas! But you’re stuck with me for another year and there are a few things that we’re going to get started in 2023 to make RWK even better. Stay tuned!

Thanks for being a RWK Member! – 73 de KD4C (feedback:

Please share any interesting ham-related stuff you’ve seen or have been doing. Doesn’t matter how raw or badly written, we’ll make you look good and help you show off what you’ve been doing – see the right column for details. With over 300 members, if everyone in the klub sent just one contribution to the Chawed Rag each year, we would have plenty of content for each issue.

This Month’s Chawed Rag Features

Winter Field Day 2023

By Chip Coker KD4C

RWK is planning a POTA-style Winter Field Day 2023 at our POTA Park-of-choice – Spring Creek Forest Preserve (in Garland – about 6 miles east of Richardson City Hall). We’re planning on a 6 hour outing (setup shortly before 12pm and operation from 1pm to 7pm. Operations will be weather permitting, so if it’s raining or very cold we won’t be there – Cross your fingers for good weather! The goal for our WFD is to 1) get on the air, and 2) Have fun! I’m encouraging fun over points but you can be as competitive as you want on the air. Again, this is a perfect opportunity for Technicians to get on the air (under the club license if you’re not on 10M, or under your own call if within the Tech allocation). There will be plenty of stations to work and band conditions have been spectacular of late. Stay tuned to the website and the list for final details and get ready to work some stations!

2023 RWK President’s Dinner

By Chip Coker KD4C

RWK held an actual live, in-person President’s Dinner on January 8, 2023! While that shouldn’t be big news, it has been three years since we were able to hold such an event (the last President’s Dinner was in 2020), primarily due to the pandemic. We had 82 members and guests, some good Italian food and desserts, good fellowship and eyeball QSOs, a recap of 2022 (a bit too long – sorry about that!), some humorous and serious awards, and 20 door prizes.

I was happy to recognize Dave Russell W2DMR has having traveled the longest distance to get to the dinner – a bit over 54 trillion miles (around the sun)! I got to provide special thanks to Logan Ki5NON and his father Travis KI5PGM for shepherding “Wheatley” throughout 2022 in support of our RWK Foxhunt program. I was proud to award Larry Pollis KI5UXC with RWK Elmer of the Year for 2022 (read more below), and I was glad to award Eric Robertson WW9K (formerly W5MWM) with the Golden Microphone as the “Voice of the RWK” for his presence on the 147.12 repeater. Eric is always quick to respond with a friendly greeting to anyone that pops up on our main repeater (which more of you should do!) and he is the embodiment of an active, involved RWK member, having participated in most all of our 2022 activities (cause you know that we keep attendance records!). We need more members like Eric!

Special thanks to Doug Kilgore KD5OUG (for wrangling Aboca’s), Shawn Prestridge KI5PXG (for his audio equipment and for providing tunes during the event), and the entire RWK Board and especially Josh Barfield N4NZ for collecting and dispatching our lot of door prizes to their new radio homes. We will have the full complement of pics uploaded to the website soon.

Chip Coker KD4C Receives the Annual RWK Warren Bruene Award for 2022

Chip Coker KD4C with his 2022 Warren Bruene Award

It is with great pleasure that I was privileged to present the 2022 Warren Bruene Award to Chip Coker KD4C at the annual Richardson Wireless Klub President’s Dinner. It was clear that the club has recognized the effort that Chip has put into the club, as he was the overwhelming winner with 2/3rds of the votes cast.

During the years that Chip has been club president, he has worked tirelessly to try and make RWK better than ever. “RWK has so much potential! With a club our size and the amount of smart, technically-minded hams that we have, RWK has the potential to be one of the best radio clubs in the state – if not the country – and that’s been my goal as RWK President,” said Chip. “We need to be creating more opportunities for our members and for new hams to promote the hobby.”

One of the first things that Chip told me when he became president was “I’m tired of us not holding VE sessions because of COVID, I know you’re doing sessions online, make something happen!”, so I did, and Chip has been at almost all of the sessions the VE team has held. With that and so many other aspects of the club, he doesn’t just participate, he leads.

Larry Pollis KI5UXC Awarded RWK Elmer of the Year for 2022

By Chip Coker KD4C

In September 2022, the RWK VE Team got a special request from a blind person that wanted to test for his Technician license. That’s when we met Austin resident Marshall Levett and found out that Larry Pollis KI5UXC had been encouraging him to study and get licensed. Larry had set Marshall up with several study resources and, as we found out, Marshall was now ready to get tested. Fortunately, Michael WT9V has some limited experience with using the ExamTools VE testing platform with assistive technologies (such as screen reading software) to test blind candidates, and we knew that it would work. So the exam for Marshall was set, and I was one of several RWK VEs privileged to watch Marshall get 34/35 on the first try for his Technician license. Marshall, who lives in Austin, also joined the RWK and has participated on several of our “Friday Lunch Bunch” Zoom calls.

Over the next couple of months. Larry continued to work with Marshall on researching which radios supported assistive technology and helped Marshall obtain a Kenwood TM-V71 with a voice module and also (in anticipation of an upgrade to General) a Kenwood TS-590S also with a voice module. Larry also worked with Marshall on studying for his General class upgrade, which Marshall obtained in December 2022 (also 34/35 and also with the RWK VE Team). Larry worked with Marshall on learning the placement of the knobs and buttons on the radio, and understanding which were active through the voice module – basically teaching Marshall how to use his new radios. Larry also installed some antennas at Marshall’s QTH in Austin. After radio installation, there was a problem with audio bandwidth that Marshall couldn’t resolve (something not covered by the voice module) and Larry helped him get it working and got him on the air! Larry continues to help Marshall as he gets started in his Ham Radio journey.

We should all aspire to embody the spirit of Elmering that Larry has shown with Marshall, and I was pleased to award Larry with the RWK Elmer of the Year Award for 2022 for his going over/above the “line of duty” to get Marshall licensed, upgraded, and on the air!


Basic Temperature Sensor using the Raspberry Pi Pico W (Part 3 of 3)

by Mike Jahrig KG5P

This month I will combine code described in previous issues and create a usable weather station application that will run on a Pico W.  This application will read data output from the BME-280 sensor, reformat it into units familiar to Americans, display it on a HTML client and also log the data as a .csr file.  In addition, it will call the NTP pool to obtain the date and time which will also be displayed and logged.

Chawed Rag Pic of the Month

Andrew Koenig KE5GDB checks the positioning and speed of the new RWK “airFiber” 1 Meter Dish, while Kevin Sims KD5YVL inspects the mounting on the roof of the Palisades Building. This dish provides a very high speed connection between RWK and DCARA’s site on Guinn Hall in Denton, some 28 miles to the northwest. This high-speed link will allow the collection of camera streams from weather cameras in multiple locations in North Texas to our camera server atop Palisades – allowing multiple municipalities to have a “bird’s eye view” of the weather. It will also support interconnection of our repeater systems in times of severe weather and networking of North Texas-Wide AREDN systems.

Ham Radio Bits & Bytes

Need A Low-Cost Mount For A Vertical?

If you want to work POTA (or even just put up a backyard vertical), this is a great (and cheap) solution. You can get galvanized 12″ nails from Home Depot or Lowes for around a buck and then use this mount. With some simple hardware, you can have a DIY vertical in no time!
