President’s Update


Greetings RWK!

I hope you’ve had a fun ham radio month and are enjoying our recently repaired UTD FM and DMR repeaters (more on this below). Thanks again to Andrew KE5GDB for making RWK’s six (!) top notch repeaters some of the best in North Texas. If you want more on DMR and Fusion, check out my September RWK meeting presentation where I attempt to describe the use of digital voice in VHF/UHF. I know it was a lot to cover but I’ve had several people tell me that it helped them understand some things they were confused about.

We had 21 people at our first RWK POTA outing and the feedback indicates that we should do more of them. Check out the pics below.

The start of October signals the start of Fall Contesting Season. For those of you that have been interested in getting started with “radiosport”, we have celebrity contestor (and owner of DX Engineering) Tim Duffy K3LR explaining all things contesting as well as Contest University (the premier event for serious contestors) and how you can take advantage of these resources. We may have some things to promote a little intra-RWK contesting competition.

This is another reminder that our annual Show & Tell Night is coming up in November, and this will be the first one in person in a couple of years. I’ve noticed, watching other clubs doing Show & Tell, that it presents some unique challenges to make it work for both the assembled group and the remote zoom viewers, so I’ll be working on the best way to do that in the next couple of months. Here’s what we would like you to show: New projects, products or things you’ve built or assembled that you use for ham radio or related activities. These are not necessarily electronics builds or things that involve soldering, rather just unique solutions that make radio easier or more fun. For example, after watching our presentation from June about the Shack rebuilding, I spied an antenna patch panel that W7UUU had incorporated into his new shack design. I’ve done something similar and I’ll be showing that off in November.

We’re not looking for an involved presentation – 5-10 minutes max and a couple of good pictures and/or the actual item. I’m betting that we can show off 8-10 items that will get people talking about how they want to do something similar. We will be creating a list closer to the meeting, but be thinking what you have that you want to show off.

A final word of thanks to those of you that donated to RWK during the North Texas Giving Day – we appreciate the support. Also a reminder that you can always support RWK through Amazon Smile and Kroger Community Rewards – it helps us and you don’t pay any more (see right column for details).

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

RWK Parks-On-The-Air Outing

By Chip Coker KD4C

On Saturday Sept 17th (after a big “Hungry Hams” breakfast for most), RWK had its first (of many?) Parks-On-The-Air (POTA) Event at the Spring Creek Forest Preserve in Garland to “activate” park K-4423. We had 20 RWK members and one guest and ended up with 5 total stations on the air during the outing.

The Event was designed to help people that were interested in POTA get experience in setting up and operating in a park-like setting, with all that entails (portable radio setup, temporary antennas, generators/battery power, etc.). We also wanted to give an opportunity to Technicians to experience HF in a semi-busy band condition (it was the weekend of the Texas QSO party and we ended up working more than a few TQP stations).

Based on everything that I’ve heard, people had fun and are interested in repeating the event. With all the setup activities of all 5 stations, not everyone made as many QSOs as were expected. Don N5SKT “activated” the park (10 QSOs are required for a station to activate) but I’m not sure how many of the other stations did. Also, we will do a better job of “sharing the mic” with the Techs that are there – I’m not sure that all that wanted to get a shot at operating got a chance.

We did learn a few things that can be improved next time! Using a VNA to tune an antenna can really QRM all the other stations trying to operate. The consensus was that 5 stations was probably too many to operate at a time, due to interference (hmm, sounds like Field Day) so future outings should be limited as to how many can be on the air at any one time. Also, antennas take longer to set up than you think they will.

Overall, people were really impressed with the low noise level that operating in a park (even one as close as Garland) provides. It’s really pretty easy to throw up a station and get on the air for a few hours if you’re prepared. Maybe Don N5SKT won’t have the park to himself for long!

UTD/TAGER Repeater Improvements

By Chip Coker KD4C

On Tuesday September 6, Andrew KE5GDB, Bryan N5HL and myself took a trip to the UTD Repeater site to do some long-awaited repairs to our equipment there. The trip was successful and everything at the UTD/TAGER site is working as intended.

Here’s what was done:

(BTW, please check out both repeaters – we would appreciate signal reports from outside of Richardson. If you need help on DMR, watch September’s RWK meeting and ask if you need help in getting your DMR programmed).

The CaHR $1000 Station Challenge

By Don Weeks N5SKT

Recently the guys at Coffee and Ham Radios (CaHR) put together a little challenge to come up with a ham shack for less than $1000 and create a video around it. I had an idea to use a radio that I have had in my shack for a while – the Hermes Lite 2.0. The original radio is no longer available but I looked and a similar unit was being sold again. So, I chose the Hermes Lite 2.0 for my $1000 station.

The Hermes Lite 2.0 is a board that was designed as a public domain project. It is based on the Apache Labs Anan radios (See resources below).

Richardson Outdoor Warning Siren Monthly Test

By Chip Coker KD4C

One of the ways that RWK “pays the City back” for all they do for us is that we monitor the proper operation of the City’s Outdoor Warning Sirens (OWS). We’ve been doing this for at least 10 years!

The City has 25 sirens that serve as an alert to the residents for severe weather or other potential event. The purpose of the sirens is to alert people that are outside to seek shelter and seek out further information (note: the sirens are not intended to be heard inside houses or buildings).

The City conducts tests of the sirens on the first Wednesday of the month at 12 noon, weather permitting. If the sky is overcast or there is a forecast for rain/storms, then most likely the test will be cancelled for that month.

If the test is not cancelled, RWK and Richardson RACES members go to each of the 25 sirens just before the test to observe that the sirens operate properly (sirens sound and rotate if capable and strobe is visible). There is a brief “net” on the K5RWK 147.12 repeater to collect the results from each siren and those are sent to the City so that any needed repairs can be made. Total time required: about 15 minutes + travel time.

We have a contingent of loyal and reliable monitors each month (thank you!), but we are looking for a few more to serve as permanent monitors. We are in the process of realigning people to sirens that are close, so most people would only have to go a few blocks to their siren. We’re also trying to get a few alternates that can serve as backups for people that need to miss a month for things like vacation.

We need your help if: 1) You’re free at noon on the first Wednesday of the month, 2) have a mobile or portable 2M radio, and 3) are able to get out and visually/audibly observe the sirens (which are mounted to 50 foot monopoles). If this sounds like something that you’re interested in and can do, then send a note to Don KG5CK ( and let him know that you’re interested in helping with OWS tests and where you will normally be at noon on Weds (home or work address).

It’s our way of paying back the City and we want to do the best job that we can, so we’re grateful for your help!


Building the QDX from QRP Labs

By Ron Guest K5IDL

The assembled QDX Kit (Photo: K5IDL)

According to the QRP Labs website, the $69 QDX is “a feature-packed, high performance, four-band (80, 40, 30, 20m) 5W digi-modes transceiver kit, including embedded SDR, 24-bit 48 ksps USB sound card, CAT control, synthesized VFO with TCXO reference”. That’s a lot for $69!

This was my first RF build and as you can tell I need to improve my winding. However I’m happy to say the instructions were excellent and it worked just fine right away. Using the board voltage taps I estimate its actual output to be around 4W. I tested its operation on FT8 using both my iMac and a RPi to run WSJT-X.

It is now serving its intended purpose: running WSPR on an RPi on an EFHW (when the antenna is not in use on my IC-7300). An operator in Australia (VK5CIA) hears it consistently enough that he emailed me last week asking for advice he could pass on to a US operator friend of his whose WSPR setup wasn’t picking up much. It was fun to build and money well spent.

Ham Radio Bits & Bytes

Don’t Be Left In The Dark

It’s hard to envision while feeling 90-plus degree heat, but winter is approaching, and with it the possibility of another round of power outages. Now is the time to think about being prepared for being without power, starting with being without lights. Jason KM4ACK shares his list of things to keep on hand.

CW Is An International Standard

You may have never thought about it, but CW is an International Standard as defined by the International Telecommunications Union (ITU). The standard exists because “a) that versions of the Morse code have been in use since 1844;
b) that it continues to be used in some radiocommunication services including the amateur and
amateur-satellite services, and to a diminishing extent in the mobile and fixed services; and c) that the code needs to be updated from time-to-time to meet the needs of the radiocommunication services,”

Last Month’s Program

Last Month we had your illustrious flunkee President presenting “DMR and Fusion and HotSpots, Oh My!”, basically everything Digital VHF/UHF. We will review how we got here, with the history of analog VHF and why we have digital VHF/UHF. We will cover the similarities and differences of the various flavors of digital radio (Fusion / DMR / D-Star / Others) and how all the digital systems can be networked together (and the similarities to AllStarlink). We’ll talk about “HotSpots” and how they can be used and why you might or might not want one. We’ll finish with what you need or want to have to use all this stuff..

If you missed last month’s RWK General Meeting, you can always watch the video available from the RWK website.
