Touch-tuned VFO
Five step sizes. Tap to switch.
Drag the VFO across the band with haptic feedback. Pick from five step sizes — 10 Hz, 100 Hz, 1 kHz, 10 kHz, 100 kHz — whatever the moment needs. RIT and XIT one tap away.
SmartLink, worldwide
Operate from anywhere on Earth.
Local network when you're home. SmartLink when you're not. Operate your amateur radio station from anywhere on Earth — same controls, same speed, same radio.
Action macros
Seven actions. One tap.
Programmable SDR hot keys for your Flex radio — a Stream Deck alternative without the dedicated hardware, host software, or per-station setup. 36 actions across 9 categories. Stack them into a single button. Color it. Name it. Pin it where you need it.
Drag-to-adjust controls
Every value is a slider.
Volume, mic gain, AGC, RF power, noise reduction — drag across the button to set it. A floating readout tracks the live value and how far you've moved. No sub-menus, no separate sliders screen — every adjustment lives right on the control.
What is a Flex Radio control deck?
Think of it as a software-defined radio (SDR) control surface that lives on the phone or tablet already at your operating position. Band buttons, mode keys, VFO, action macros — every control an amateur radio operator reaches for most, one tap away instead of buried in SmartSDR menus. No extra hardware. No host software. Just your FlexRadio and your phone.
ControlDeck doesn't replace Maestro — it complements it. Maestro stays bound to the radio; ControlDeck rides alongside as the touch surface for the controls and macros you use most. They're built to coexist on the same desk. New to ControlDeck? Get started here.
Stream Deck vs. ControlDeck.
No contest.
Amateur radio operators buy a $150–$300 Stream Deck just to get programmable hot keys on their FlexRadio. ControlDeck delivers the same capability on the phone already in your pocket — no extra hardware, no host software, no per-station setup.

|---|---|---|

| Host software | Required on a Mac or PC | Computer-agnostic — talks to your Flex directly |
| Customization | Stream Deck Studio + per-plugin setup | Built-in editor designed for radio |
| Buttons | 15–32 physical keys | 41 touch controls · 36 macro actions · 9 categories |
| Remote use | Tied to your operating desk | SmartLink — operate from anywhere on Earth |
