Hello, I’m Eric.

I’m a new ham exploring local repeaters, internet-linked radio, digital modes, APRS and whatever hand-me-down equipment lands in my shack.

My Story

How I Got Here

In the fall of 2023, I ran into a friend on the street and noticed an unfamiliar emblem on his shirt. He confirmed that it had something to do with ham radio, so we met for coffee and he told me about the Henderson Amateur Radio Club.

Beyond The Horizon

HF is missing but not forgotten.

I’m honing my skills with VHF/UHF gear and applications to prepare for my transition to HF.

Community

All radio is local.

Thanks to the organizations that turned my vague idea into reality.

A desert station deserves a proper card

Amateur radio is described as a technical hobby, which is true in roughly the same way a kitchen is a collection of appliances. Yes, the equipment is important, but it’s people who bring radio to life. My journey is possible because other hams shared their time, tools, expertise, and passion.

Lynem

Lynem is a man of infinite patience. After sitting down with me and explaining what amateur radio had to offer, he waited nearly three years for me to take the exam. When I was finally ready, he directed me to the free testing offered by the Las Vegas Test Team and met me at the exam center to wish me luck.

Once I had gotten my feet wet with repeaters, Lynem gave me a digital radio. That gift started my journey into DMR.

Thank you, Lynem, for introducing me to amateur radio and waiting patiently for me to follow up. 73

Volunteer Examiners

Las Vegas Test Team and Laurel VEC

The Las Vegas Test Team is committed to the Laurel VEC mission of bringing free license exams to aspiring amateur-radio operators. Its Volunteer Examiners selflessly give their time so others may experience the joys of our community.

The job is not easy. During my General and Extra exams, my assigned laptop malfunctioned four times. Each time, the VEs caught the error before my answer sheet was lost.

Thank you, Las Vegas Test Team and Laurel VEC, for your dedication to amateur radio.

Dr. William “Bill” P. Freeman

As a new Technician armed only with a Baofeng 5R Mini, I had one question: “Can I make it into a repeater with this thing?” I found a nearby machine hosted by N4NJJ and the Sin City Repeater Group. Being cautious, I read through the materials on the Sin City website. The message was clear. If I wanted to know what the group was about, I should key up and say my name. That is what I did, and I made my first QSO with KD6SIN.

Shortly after, I made contact with Bill. He gave me a warm welcome to the repeater and the amateur-radio community. I’ve learned a lot from Bill, from buying used equipment on QTH.com to knowing when to step off the microphone so other stations can get in. When the Sin City Repeater Group opened its books, I was proud to become a member.

Thank you, Bill, for being a role model for a new ham trying to find his way.

Rick · Mayor of the Mighty 444

I first made contact with Rick through the Buffalo repeater system linked to the Sin City Repeater Group. He gave me a warm welcome, encouraged me to participate in the amateur-radio community, and asked what had motivated me to become a ham.

Rick knows something about motivation. After earning his license in 1982, he left radio in 1998. He returned twenty-five years later and became the Mayor of the Mighty 444.

Thank you, Rick, for teaching me that all radio is local and that there is a place for everyone in the community.

Tim

I was happy to receive a Motorola XPR 3500, right up until I had to program it. Motorola locks down parts of its software, requiring authorization keys for certain functions. After searching in vain for a workaround, I took a break and checked in on the repeater.

I mentioned my Motorola struggle, and within moments N2LCJ, Tim, broke into the conversation. After exchanging a few emails, I had what I needed to program the radio.

Thank you, Tim, for helping someone who was only a voice on the other side of the radio.

Gene

I met Gene through the Henderson Amateur Radio Club. His mild-mannered demeanor belies a keen technical mind. When he is not designing pocket picos, he restores old radio equipment with K7MLG. I should not have been surprised when Gene turned up with a vintage mobile radio, but I was.

Buying a new car torpedoed my entry into HF and dramatically curtailed my plans for a mobile radio. I had decided to delay the project when Gene produced an old but serviceable Motorola CDM1250 and helped me work through the power-supply issues.

Thank you, Gene, for encouraging me to stay the course and showing me the power of improvisation.

Mike and Darren

Mike is a strong advocate for APRS and manages the weekly #APRSThursday net. It was my privilege to attend his presentation at the June 2026 Henderson Amateur Radio Club membership meeting.

Packet radio was a mystery to me. I had heard of it, but I did not understand how it worked or even what it was for. Mike provided the fundamentals I needed to get started, and I checked in to #APRSThursday that same week using APRSDroid.

Following the presentation, Darren shared several of the APRS devices he uses, including an inexpensive LoRa iGate with a bidirectional LNA. I was blown away by what he had achieved with a $20 development board. His example inspired me to set up an iGate of my own.

Thank you, Mike and Darren, for sharing your knowledge of and excitement for APRS.

Doug

Doug is a man for all seasons, and he brings the same energy to amateur radio. He has a clear picture of what ham radio ought to be, respecting its culture and traditions while embracing the evolution of the technology.

Doug taught me that filling out my QRZ page is good citizenship. Other operators want to know there is a real person behind the callsign, engaged with the community.

Thank you, Doug, for inspiring me to maintain my QRZ page, which led to the creation of this website.
