RemoteQTH - Band decoder with another TRX control output for Arduino

This page wait for upgrade, last version is here
Production of the Band decoder has been discontinued, but you can build your own, based on the available source code.

Band decoder with another TRX control output or remote IP Relay

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 (including TS-x50 with TTL inverter add-on )
- Yaesu CAT (TRX since 2008
- Yaesu BCD
- Icom ACC voltage
Outputs
- Remote IP Relay need version with TCP232 ethernet module. NEW
- 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.

	Notes: ✔ Need two components - IP Band decoder (master) and external remote IP RELAY (slave) - Names input and output serves as a direct link to the wiki. - Kenwood and Yaesu CAT can use either Frequency request or any from CAT/CIV output, not both at once. - Yaesu CAT for TRX since 2008 (ASCII format). - Kenwood CAT also old TS-x50 version, with TTL inverted add-on . * Icom CIV Frequency request not supported in this hardware.
