Ham Mixer Mobile

HamMixer Mobile turns your iPhone into a full remote control for your ham radio station. Connect securely to HamMixer Server at your home QTH and operate your transceiver from anywhere in the world -- with real-time audio, full radio control, and near-zero latency.

Designed by CT7BAC, a licensed ham operator, for ham operators.

REMOTE RADIO CONTROL
- Set frequency with a velocity-sensitive tuning wheel and haptic feedback
- Switch bands (160m-6m) with one tap and automatic band memory recall
- Change modes: LSB, USB, CW, AM, FM
- Toggle DSP controls: NB, NR, ANF, Preamp, AGC, IF Filter
- Adjust RF power, control the antenna tuner, exchange VFO A/B
- Real-time S-meter with peak hold, TX power and SWR indicators
- 7-segment frequency LCD with live band plan display

REAL-TIME WATERFALL
Full-screen landscape spectrum scope with drag-to-tune, frequency snapping, adjustable contrast, and edge cycling. Native Icom scope data streamed over the network.

VOICE MEMORY & CW KEYER
- 8 customizable voice memory buttons (M1-M8) for voice keyer playback. In CW mode, buttons switch to programmable CW macros.
- Character-by-character text-to-morse keying with adjustable speed (6-48 WPM). The radio handles all timing -- immune to network latency.
- Connect a CW paddle to the BLE accessory module for real iambic keying (Mode A/B) with low-latency local sidetone. The keyer runs on your phone -- network latency does not affect your timing.

QSO LOGGING
Tap the frequency display to open a dedicated log screen. Band, mode, and frequency auto-fill from live radio state. Scroll-wheel time pickers and RST selectors. Includes its own PTT button and CW entry so you can keep working the contact while logging.
