This evening, I spoke to the Whitley County Amateur Radio Club about digital mobile radio (DMR). Here is a link to my presentation slides for reference:

NWS needs storm spotter photos
The National Weather Service (NWS) is preparing to revise the web page for its Skywarn® storm spotter program. The agency is seeking photographs to use on the revised web page.
Photographs should depict real-life, safe and responsible spotter activities. Examples include a ham radio operator holding a handheld radio while looking at the sky, or a spotter typing a message on a smart phone, etc. The ideal photos imply action (vs. portraits) and are set outdoors. Due to government policies, NWS declines to use photos of spotters sitting behind the steering wheel of a vehicle while using a mobile radio.
Skywarn volunteer Jay Farlow is gathering photos for a contact at NWS, so contributors should send the photos to arsw9lw@gmail.com by March 31. Contributors should provide contact information of each photographer, so the NWS can confirm it has permission to use the photos.
W9LW’s TYT MD-380 codeplug programming guide
I have created a guide to help users of the TYT MD-380 handheld, DMR amateur radio create codeplugs for their radios.
The link below will provide the latest version of the document.

COVID-19 pandemic affects SKYWARN severe weather operations
Restrictions implemented to slow the spread of COVID-19 will affect one of the ways SKYWARN® storm spotters send reports to local National Weather Service (NWS) offices. Many NWS weather forecast offices (WFOs) have amateur (ham) radio equipment permanently installed. During severe weather events, volunteer ham radio operators operate that equipment to receive reports of tornadoes and other dangerous weather from fellow hams who are storm spotters.
Now, however, the NWS is forbidding anyone not directly connected with the agency from entering WFOs, according to NWS Northern Indiana warning coordination meteorologist Michael Lewis. That means that ham radio stations at WFOs are less likely to be on the air during severe weather events. Some NWS meteorologists have ham radio licenses and some of those might be able to sporadically operate WFO ham stations. But Lewis told me that to reduce exposure to disease, the NWS is trying to operate WFOs with as few people in the office as possible. This might mean that NWS meteorologists who have ham licenses will have no time to operate the ham radio equipment.
Ham radio operators will still be able to use their radios to report severe weather, but they’ll need someone other hams to relay those reports to their local WFOs. That’s where an internal NWS text chat system will be essential, Lewis said. The system is called NWSChat and access is limited a select population. That groups includes ham radio operators who serve as net control station operators. Local ham radio SKYWARN groups can (and should) designate such leaders to serve as liaisons between the radio networks and NWSChat.
Whether or not spotters have ham radio licenses, other ways to communicate reports continue to be available, including telephone calls to WFOs and Twitter tweets that include the appropriate WFO’s Twitter handle.
The voice communication app Zello can also be helpful to SKYWARN storm spotters. Unfortunately, Zello’s terms and conditions do not comply with federal government requirements, so NWS WFOs are prohibited from installing Zello on any government-owned devices. A specific Zello channel exists (“IWX SKYWARN”) for reports from areas covered by the Northern Indiana office. Because WFO staff are prohibited from using Zello, ham radio net control station operators, who have NWSChat accounts, plan to monitor the Zello channel as much as possible, to relay reports from spotters to the WFO.
All this could be tested tomorrow, March 19, when severe weather is forecast in much of Indiana.
WeatherBrains podcast features amateur radio’s role in the weather enterprise
A popular, weather-related podcast recently recorded an episode devoted to the role of amateur (ham) radio in the weather enterprise, especially storm spotting. WeatherBrains is a long-running, well-respected podcast hosted by Alabama broadcast meteorologist James Spann. It recorded the ham radio podcast January 7.
Ham radio has been deeply involved in the National Weather Service’s (NWS) SKYWARN® program since its inception, according to research done by Brian E. Smith, the warning coordination meteorologist at the NWS Omaha/Valley weather forecast office (WFO) in Nebraska. During the infamous Palm Sunday tornado outbreak of 1965, a tornado did F4 damage in northern Toledo, Ohio. Afterward, a ham who was also a meteorologist in the Toledo office of what was then called the U.S. Weather Bureau — Merle Kachenmeister, WA8EWW — organized ham radio operators in his area to report severe weather to the Toledo office via radio. This is considered the birth of the SKYWARN program, according to Smith.
WeatherBrains episode number 677 is available for viewing or listening on the the podcast’s website. Listeners can also access the audio-only version on their mobile devices via their favorite podcast apps.
The author of this blog was one of the guests who WeatherBrains invited to discuss ham radio. Other guests included Jeff Stapel, W8SWX of the Muskegon, Michigan SKYWARN organization and Rob Macedo, KD1CY, who is both the Section Emergency Coordinator of the ARRL Eastern Massachusetts section and director of operations for the VOIP Hurricane Net.
During the show, I mentioned several resources that might be valuable to audience members. For your convenience, I’ve listed them below:
- ARRL, the national association for amateur radio®: This website contains a wealth of information about amateur radio, what hams do, and how to become a licensed ham radio operator.
- The tornado outbreak of Aug. 24, 2016: This page on the website of the NWS northern Indiana WFO includes the radar rotation tracks I showed during the podcast, as well as other information about how the outbreak affected my home area.
- ARRL Ham Radio License Manual: This book contains all the information you need to pass the exam and get your ham radio license, so you can join other storm spotters on the air.
- Storm Spotting and Amateur Radio: This book is a valuable resource for anyone who is interested in either storm spotting or how to use ham radio while spotting. It includes information on resources, training, equipment, safety, storm spotter activation procedures and more.
- Allen County (Ind.) SKYWARN Net Operations Manual: This PDF document discusses in great detail how the hams of the Fort Wayne and Allen County, Indiana area organize their SKYWARN net — i.e. on-air conference call — during severe weather events.
A couple resources I didn’t have time to get into regard equipment (although Rob mentioned some price ranges). Below are links to some equipment options you might consider, if you’re thinking about getting into ham radio:
- Baofeng UV-5R handheld radio: Available on Amazon for only $25, this will get you on the air. Like any handheld radio, its geographical range is limited, but as long as you’re close enough to what hams call a “repeater” station, you can talk to people dozens of miles away.
- AnyTone AT-778UV Mobile radio: Available on Amazon for $130, this radio mounts in your vehicle and connects to your vehicle’s 12-volt poser source. It transmits with 25 watts, versus the 5 watts of most handheld radios, enabling you to communicate while farther from the repeater station. It requires an external antenna, sold separately. Antenna options include those with temporary magnetic mounts and those that can mount more permanently on a trunk lid without drilling holes.
The “big three” brands of ham radio equipment are Icom, Kenwood and Yaesu. Their radios, while well respected, tend to be priced higher on the new market than the Chinese brands above. Note, however, that there’s a large market for pre-owned radios. These can be obtained through some dealers (who take trade-ins), at ham radio flea markets and through online auction sites.

Ham radio operators configure weather radios for citizens
Five radio amateurs assisted members of the general public with configuring weather alert radios during a special event last month. The Kroger store at Georgetown Square on Fort Wayne’s northeast side hosted the April 16 event, which was organized by WANE TV-15 and the Allen County Office of Homeland Security (ACOHS).
Ham radio participants included Tom Baker, N9TB; Al Burke, WB9SSE; Jay Farlow, W9LW; Steve Haxby, N9MEL; and Howard Pletcher, N9ADS. Mark Frazier, meteorologist in charge of the Northern Indiana National Weather Service Office also participated, as did Lori Mayers, assistant director of ACOHS and WANE broadcast meteorologist Greg Shoup and Adam Solarczyk.
After the three-hour event, WANE chief meteorologist Nicholas Ferreri wrote, “Thanks for gathering such a great group of Fort Wayne area volunteers for Monday’s kickoff to WANE Weather Radio Week. I’ve heard many good reviews about Monday’s event.”
Bruce Jones, meteorologist/spokesperson for manufacturer Midland Radio Corporation added, “We appreciate everything SKYWARN/ARRL does to support weather safety both before and during severe weather events. WANE-TV is helping get the word out there and with partners like you, Lori, and Mark we are building the NOAA Weather Radio audience bigger and bigger every year. We estimate there are 15-20 million weather radio receivers in the US and Canada and it is important that we keep them all operational and properly tuned. So in addition to setting up new radios, thank you for troubleshooting the older models.”
Promote weather safety by posting a #SafePlaceSelfie
April 4, 2018 is national safe-place selfie day. It’s a campaign to help educate people about safe places to take shelter, especially during dangerous weather. The National Weather Service explains the campaign on its website.
You can help with the public education effort by simply going to your shelter (whatever it is at your location), taking a photo of yourself and then posting that photo on your social media channels, along with the hash tag #SafePlaceSelfie.
For example, I posted the photo above on Twitter, Facebook, Instagram and SnapChat.
Show the world how you shelter! Post a #SafePlaceSelfie.
Still no way to get messages to Puerto Rico, even as new hams arrive
A group of 50 volunteer amateur (ham) radio operators from the U.S. mainland are on their way to Puerto Rico, to provide much-needed communications at Red Cross shelters there. But even after they arrive and set up, there still will probably be no way to get messages to the island.
The mission of the ham radio operators that the American Radio Relay League (ARRL, the national association for amateur radio) is deploying will be to send information from the island, according to an email message from ARRL staff member Steve Ewald. Specifically, they’ll send information about the welfare of survivors, so worried family members on the mainland will finally know their loved ones are OK.
But no one will contact those families directly.
As the survivor data reaches the mainland, other volunteers will enter it into the Red Cross “Safe and Well” database, where family members around the world will be able to access it via the web.
So, as I wrote in an earlier blog post, the only resource for worried family members remains checking the Safe and Well web site. If a Puerto Rico resident is not listed, family members can only check again the next day, and the next. After newly deployed hams get in place and start sending survivor data off the island, the number of survivors listed on that website should grow quickly.
