Forest Fire Smoke Propagation — Menu

Adrien Guyot, et. al. published a recent paper on the effect on radio signals as they travel through smoke fields that are generated by large wildfire events. Their paper talks about using these signals to provide an early warning to people in the path of a fire. During our April meeting, Gordon West WB6NOA discussed the effects of temperature inversions on radio signals. In that presentation Gordo talked about noticeable changes in the VHF amateur band.

This study uses data from commercial microwave links, that range from 6 GHz to 86 GHz. These towers were in and around the massive 2019/2020 fires in the Melbourne, Australia area. They studied the received signal level at the tower locations and observed the changes as they related to the reported smoke density measured at local air quality stations. Link lengths of 5 to 20 km provided the best results at predicting the atmospheric changes.

I wonder what could be learned from FT8/WSPR data on the lower bands? Our friends at HAMSCI did a similar study on the effects of the 2017 solar eclipse on radio propagation. In 2018, Nathan Frissel, et. Al. published their findings on their study of the 160 M, 80 M, 40 M, and 20 M bands during the eclipse.

Next time you hear some strange propagation events or see some strange callsigns on your computers or radios, take a look at the solar weather, physical weather, fires, air conditions, or other physical properties that may be affecting your signals. Something to think about when the next dry season comes along…

DMR Server Change — Menu

Brandmeister has announced that it will be shutting down its 3101 New York server on December 1, 2021. Due to unforeseen circumstances, the New Your server will be shut down. Most of us in the Oklahoma area chose the 3102 Dallas, TX server, however, your hotspot may be going through one of the others.

If you want to check a certain repeater, you can click this link and enter the repeater callsign.

If you want to check a certain DMR hotspot, you can click this link and enter the hotspot callsign.

Brandmeister is suggesting 3101 users transition to the 3104 Chicago server now.

3102 – Dallas, TX –
3103 – San Jose, CA –
3104 – Chicago, IL –

Check your repeater! or hotspot and if it’s using 3101, make the switch today!

Repeater Etiquette — Menu

To encourage proper operating guidelines, we provide members a guide to repeater etiquette and operating guidelines. Our on-the-air guidelines are listed here and are available on the SCARS website at Following these will help new members and not-so-new members get up to speed with the protocols, language, topics, and operations on shared radio systems.

The Federal Communications Commission (FCC) has created rules and regulations that govern amateur radio. These rules and regulations are listed in Title 47, Chapter I, Subchapter D,  Part 97 of the Code of Federal Regulations. Hams usually call these the “Part 97” rules. Those rules discuss what hams are legally allowed to do.

However, just because you can do it doesn’t mean that you should do it. Learning what you should do usually takes many years and involves a lot of hard lessons. In an attempt to help learn these lessons quicker, we have created this repeater etiquette guide.

Repeaters allow us to amplify our signal to allow others to hear our voices. SCARS repeaters, and all others, typically have hundreds of people listening at all times. This could be hams, family members of hams, people listening to scanners, city officials, or people listening on the Internet rebroadcast or recording, anywhere on the planet. When you are heard on a repeater, your performance should be representative of the host club.

Follow these guidelines and you will quickly become a better operator.


  • Take time to listen to the repeater for a while before you transmit. If you are new to the area, listen to get a feel for the operation of the locals. Otherwise, listen for at least 30 seconds to make sure you aren’t barging into a conversation.
  • To transmit, key your microphone, wait for a second, and then start talking. Repeaters and receivers have a built-in delay that may chop off the first few syllables of your statement. Hold the button firmly while you are talking. Be sure to let go of the button when you are finished.
  • Transmit your callsign when you start talking. This lets the other people listening know who you are. While the person you are talking to may know your voice, others listening may not.
  • If you wish to announce that you are listening to the repeater and are willing to converse, give your callsign and the words “listening” or “monitoring.” Stay on the channel for at least a minute because others may take a while to respond. CQ is not used on repeaters.
  • To call another station, transmit their callsign and then your callsign. Be sure to pause before you start talking. If you get no response, make this call again. If you still get no response, simply transmit your callsign and the words “clear”, or “listening”, or “monitoring”.
  • Resist the urge to quickly key to respond to a transmission. Provide a brief pause between transmissions to allow others to join in. People breaking into a conversation will transmit their call sign when the current operator unkeys.
  • Promptly acknowledge any stations that transmit their call and permit them to either join the conversation or make a quick call.
  • You do not need to wait for the repeater transmitter to drop. There are about four seconds between the courtesy tone and the repeater transmitter dropping. Let two of them go by and then key the microphone.
  • Commuting hours are popular for many mobile stations. Repeaters exist to help extend the range of mobiles and portables. Be courteous and give them priority during commuting hours.
  • Do not “kerchunk” a repeater by clicking the microphone button to see if you are in range. If you need to range check your radio, key the microphone, transmit your callsign, and then wait for the repeater to respond.
  • To ask for a radio check, key your microphone, transmit your callsign, and then the words “radio check”. More often than not, you’ll get someone to respond.
  • If you are in an emergency situation, use the word “emergency”. You will get a much better response than if you use other codewords. When someone responds, keep them informed of your situation until you announce that the emergency is over.


  • Watch what you say when you key your microphone. Speak as if your mother is in the room. Avoid ‘mild’ obscenities, including suggestive phrases and innuendos.
  • Speak as if you were talking to someone face-to-face.
  • Don’t use the word “break” to join a conversation. If you want to be involved, simply transmit your callsign. Some regions reserve the word “break” for announcing an emergency.
  • Use plain language and avoid jargon or acronyms that may be prominent in your ‘day-job’, or on HF. Others may not fully understand what your acronym means.


  • Do not monopolize the repeater. If others turn off their radios because they can hardly talk to someone except you, something is wrong.
  • Be upbeat and courteous. Don’t be the guy that’s always complaining about other hams, the repeater, or some aspect of the hobby.
  • Do not discuss the topics of politics, religion, or make disparaging remarks. While you and the person you are talking to may share certain beliefs, there are hundreds of other listeners that probably have differing opinions. Typically this results in hams turning off their radios and reduces group participation.
  • If you frequently receive jamming interference, it may be a sign that you may need to adjust your use of the repeater. This isn’t always the case, but history has shown that jammers respond to those that have caused the most friction.


  • Don’t cough, sneeze, or clear your throat on-the-air. Unkey the microphone as you feel these coming on.
  • If you hear someone trying to “jam” a transmission, or disrupt the normal repeater operation, ignore them. These people are looking for attention and typically go away if ignored. “Please don’t feed the trolls.”
  • If you feel that you need to interrupt an existing conversation, remember it is no more polite to do so on the air than if you did it face-to-face.
  • Follow a roundtable, or rotation format to allow 3 or more hams to participate in a conversation. Don’t ignore people by not passing to them for several turns.
  • Perform your legally required station identifications every 10 minutes. Use the repeater timer, or the other station as your guide. When you hear the controller identify the repeater, you should give your callsign on the next transmission.
  • Using the phrase “for ID” with your callsign is not required, or encouraged.
  • Perform your legally required station identification at the end of your conversation. Simply give your callsign. You do not need to repeat the callsign of the other operators.
  • Don’t use any CB phrases, slang, or verbiage. Use plain language.
  • Respond to calls that you aren’t familiar with. It’s a great way to meet new people and hear new stories. They may be a new ham, or new to the area, and are looking for a conversation.

Have fun and enjoy the machines. Should you have a question or would like to add to this list, please send a message to

QRZ056: Rumors Fly: Zedd to Wed? — Menu

This ongoing series was written by SCARS charter member SK Jack Bickham WB5TZZ / KU5B. Jack was a prolific novelist, his two most known works were turned into the movies “The Apple Dumpling Gang”, and “Bakers Hawk.” These 104 Q. R. Zedd articles were originally published in the Central Oklahoma Radio Amateurs (CORA) Newsletter, the Collector & Emitter from September 1981 through April 1990, and are hosted on the SCARS web site. We are reprinting this series to provide you with a glimpse of the past.

Originally published in the April 1986 issue of the C&E.

Fresh from his triumphant opening of Atlantis for the DX faithful, Oklahoma’s Q. R. Zedd was back in the news this week as marriage rumors circulated worldwide.

Zedd, whose Honor Roll Ranch is just a hoot and a holler south of town, holds the nation’s only 1×1 callsign, A5A, and was recently named first recipient of Britain’s new Order of the Yagi in recognition of his Atlantis feat. He is known by many for his invention of radar and the plastic milk bottle, and annually bests all the rest in worldwide Dx competitions.

Most of these feats paled this week, however, as — for the second time in recent memory — word spread over the airwaves that the great man may wed Tondelayo Schwartz, his blonde, nubile, QSL secretary and constant companion.

Word from the French Riviera, where Zedd and the darling girl were vacationing after their Atlantis trek, was that A5A was QRZ on the airwaves only about 17 hours per day, while Tondelayo, W5FPN, was heard at her high-speed CW keyer only 15 hours per day from the beach. While it is well known that the couple ranks among the globe’s greatest ballroom dancers since Astaire and Rogers, dancing alone could not account for so many hours away from their rigs. This was the source of the romance rumors.

A fabled jeweler on the Riviera leaked to the National Enquirer a report that Zedd had bought Tondelayo another engagement ring. Tondelayo threw the last one in Lake Thunderbird two years ago when Zedd left her (and the Rev. Billy Graham) at the altar in order to rush off on a jet and activate Vietnam on all bands.

In Rome, the Swiss Guards at the Vatican all had their shoes shined, adding fuel to the rumors that the great one and his constant companion might have decided to tie the knot at last, and let the Pope do the honors while they were in the neighborhood. The Vatican had no comment, and the Vatican ham station was QRT.

Contacted on CW by a reporter for the Collector & Emitter, the precious Tondelayo was non-committal. The exchange went like this:

QRZ 5 K 
KU5B 59 59 KN 

Zedd, as is well known, was married once before, years ago, but the marriage was later annulled on the basis that it had never been consumated, the ceremony having taken place during a record peak in the solar flux which kept Zedd at his rig for two years running. His once-betrothed later married a CBer and did other bad things.

Zedd has been with Tondelayo, or vice-versa, since they met on the beaches of southern California when she was 16. Her parents first objected to her joining Zedd, then 54, fulltime at Honor Roll, but that objection ended when they met the great one and saw how wonderful he was, and he promised to keep Tondelayo in high school, and tutor her on the side.

Zedd did such a great job of tutoring Tondelayo that she graduated from high school in a matter of days, and went right on, to the Harvard Business School, where she racked up a perfect 4.0 grade point average and graduated Maxima Cum Laude in a little over a year. She then returned to Oklahoma and used her new skills to takeover all Zedd’s QSLing and logging.

Tondelayo has made no secret of her adoration of Zedd, and didn’t even whimper very long when he left her (and Billy Graham) at the altar for Vietnam. Zedd’s momma, Constance Wilhemina Zedd of Mena, Arkansas, approves the pairing and has often said she wants a grandbaby.

“I just hope it works out this time,” Momma said via 40 meter phone from Mena. “That girl is not getting any younger, and if she doesn’t catch him this year, then the sunspot cycle will start to, improve again and she may have missed her last chance.”

If there is truth to rumors of impending nuptials; all the faithful should know by next month this time. Zedd’s private jet is scheduled to return stateside on or about May Day;
