Your FlexRadio Deserves a Real Meter SmartMTR brings the soul of classic analog instrumentation to your FlexRadio FLEX-6000 and FLEX-8000 series. Two independent S-meters, four live TX needles, on-meter frequency and mode controls, a real-time spectrum analyser, and a built-in recorder — all in one beautifully crafted companion app for macOS and iOS.
Operate Directly from the Meter
Scroll or click the meter face to tune frequency, switch bands, change
modes, adjust filters, and select antennas — no need to leave the
window. SmartMTR remembers your settings per band so you can jump back
instantly. A dedicated Filters window gives you full control over AGC,
noise reduction, notch, and peak filters for each slice.
See Everything at a Glance
Choose what lives in the center dock: a 32-bar FFT spectrum analyser, a
rolling signal history chart, a UTC clock, or custom labels. During
transmit, four animated TX needles show SWR, compression, RF power, and
mic level in real time — no menus, no text readouts, just needles.

Built for Hams Who Care About the Details
SmartMTR connects to your FlexRadio over the local network via the
official API, subscribing to real-time UDP meter data for silky-smooth
needle response. It is a dedicated auxiliary client — your main SDR
software stays in control while SmartMTR gives you the professional
analog display your station deserves.
