Simplex is amateur radio at its core—radio to radio, no repeaters, no middleman. Just you, your station, and the signal. Repeaters are convenient, but they’re not guaranteed. When they go down—storms, outages, whatever—simplex is what keeps you on the air. It’s not just a skill… it’s real capability. But here’s the part most people miss—simplex is fun. This is where the hobby comes alive. It’s your antenna, your setup, your operating skill making the contact happen. And no—it’s not “just a few miles.” With a decent station, 50–80 miles on 2 meters is very doable. Catch a little propagation and you’re talking 100+ miles, sometimes a lot more. That’s where the magic happens. Locally, simplex works every day—mobile to mobile, base to base—solid, reliable, and engaging. If you’ve never really tried it, you’re missing one of the best parts of the hobby. Give it a shot. Call on 146.520. Build your station. Improve your signal. Experience radio the way it was meant to be—direct, capable, and seriously fun.
What is Simplex?
Simplex operation means direct radio-to-radio communication without repeaters. On VHF/UHF, this is where skill, station setup, and operating technique truly matter.
📡 Direct RF Path
No infrastructure. No repeaters. Just your station and theirs.
⚡ Why We Love It
Simplex is challenging, unpredictable, and rewarding. Every contact is earned.
🎯 Skill Over Power
Height, terrain, and takeoff angle matter more than brute force power.
🌎 Real RF
Tropospheric ducting, scatter, and weak signal propagation make every day different.
How Simplex Works (VHF/UHF)
Line-of-Sight
Signals generally travel in straight lines. Terrain plays a HUGE role.
Takeoff Angle
Lower takeoff angles = longer distance. Antenna placement is critical.
Frequency Examples
146.520 MHz – FM Calling
144.200 MHz – SSB Calling
50.125 MHz – 6m Calling
Modes
FM for local. SSB/CW for distance. Digital for weak signal extremes.
The Challenge Factor
Terrain Matters
Valleys kill signals. Hills create opportunity. Height wins.
Station Design
Low-loss coax, directional antennas, and clean signals make the difference.
Operator Skill
Knowing when and where to call is just as important as equipment.
Weak Signal Fun
That barely readable signal? That’s the one that makes your day.
Why It Matters
Simplex keeps Amateur Radio alive at its core. It builds skill, independence, and real understanding of RF propagation. No internet. No infrastructure. Just radio.
