The Radio

Big signal.
Small pack.

The QRO20 is a 320 watt, LiPo battery-powered, low cost 20 meter software-defined radio that uses polar modulation to efficiently deliver up to 320 watts of peak effective power from a rig you can carry up a mountain.

Featuring CESSB, an automatic antenna tuner, and an ultra-high dynamic range receiver — this is the perfect radio for your next POTA / SOTA activation.

No linear amplifier, no generator, no compromise. Just a compact, efficient transceiver built to put out a real signal from wherever you happen to be standing.

Why QRO20

Built for the field

01 / POWER

Polar Modulation

Delivers up to 320 watts of peak effective power with high efficiency, so a LiPo pack can last through a full park activation.

02 / AUDIO

CESSB

Controlled Envelope SSB shapes your audio for maximum average power and punch through the noise — without splattering your neighbors.

03 / MATCH

Automatic Antenna Tuner

Built-in tuner sweeps and matches your wire or whip automatically, so you spend less time fiddling and more time making contacts.

04 / RECEIVE

Ultra-High Dynamic Range RX

A receiver designed to stay quiet and linear next to strong signals, so weak stations don't get buried on a crowded band.

05 / POWER SUPPLY

LiPo Powered

Runs directly from common RC LiPo packs via XT60 — light, rechargeable, and easy to source anywhere hobby batteries are sold.

06 / CONTROL

Live PC Control Software

Real-time spectrum, waterfall, VSWR, and Smith chart antenna impedance — all from a purpose-built desktop control app.

Control Software

See what you're working with

The QRO20 pairs with a dedicated control application that puts everything on one screen: frequency, power, VSWR sweep, live antenna impedance on a Smith chart, and a real-time spectrum and waterfall display — all updating as you operate.

Live Waterfall

Watch band activity and your own signal in real time.

VSWR Sweep

See your match across the band before you transmit.

Smith Chart

Antenna impedance plotted live as the tuner works.

Power & Voltage

Battery voltage and RF output tracked every block.

Performance

A clean signal, not just a loud one

Polar modulation and CESSB are only worth using if the result is spectrally clean. This two-tone sweep shows the QRO20's transmit chain holding intermodulation products well down — a strong, efficient signal that stays inside its lane on the band.

Fit & Finish

Made to be carried, built to be seen

The black anodized, finned enclosure carries the QRO20 mark etched straight into the lid — a clean, permanent finish that won't rub off in a pack or peel in the sun.

Under the Hood

Purpose-built, not repurposed

Every watt has to go somewhere. The QRO20's power stage is built around a finned aluminum enclosure that doubles as the heatsink, with forced-air cooling backing it up when you're running long transmissions at full power.

It's a from-scratch design — RF power amplifier, relays, and control electronics all packed into a case small enough to fit in a backpack pocket next to your battery.

Connectors & Layout

Simple, rugged I/O

QRO20 front panel with antenna connector and XT60 battery input

Antenna & Power

A type-N antenna connector with UHF SO-239 adapter and an XT60 LiPo input, milled into a brushed aluminum end plate.

QRO20 rear panel with ventilation slots and control connectors

Control & Ventilation

USB connection to PC, indicator LED, and a 6-32 ground connection, alongside ventilation slots that keep the QRO20 running cool.
