TinyDX Config WB2CBA · V1.5

Configures the four operating frequencies (2 bands × FT8/FT4) and the Si5351 calibration factor, stored in the radio's EEPROM. TinyDX supports 14 MHz (20 m) – 30 MHz (10 m) only. TX also depends on the fitted low-pass filter. Works in Chrome/Edge on desktop or Android — iPhone/iPad are not supported (no iOS browser can access USB serial).

Firmware update bundled V1.5

Flashes the bundled firmware to the radio via its bootloader. Keep the USB cable connected and do not unplug during the update. Your saved frequencies and calibration (EEPROM) are preserved. Desktop Chrome/Edge is fully supported; Android (WebUSB) is best-effort.
