New ! Band decoder with another TRX control output for Arduino

Allows you to read the frequency or band data from your transceiver and switch output relay(s) by the defined rules . Another feature allows you to send frequency to another Icom or Kenwood transceiver (synchronize tuning). Suitable for switching antennas, RX/TX filters, PA, transverters…

Main functions:

Available Inputs
- Serial ASCII
- Icom CIV
- Kenwood CAT
- Yaesu BCD
- Icom ACC voltage
Outputs
- 14 Relay (0,5A/125VAC, 1A/24VDC)
- USB serial ASCII echo
- Yaesu BCD (relay 11-14)
- Icom CIV
- Kenwood CAT
Watchdog – if input data missing all relays go OFF after defined time.
Fourteen LED output indicated.
Configureable in arduino source code.
Open code – you can modify.
Arduino NANO module compatible.
5V power voltage from USB mini plug.
Size 22x3x7cm.
Weight 270g.
