Band decoder for Arduino

Input Serial

Activate uncomment line

#define INPUT_SERIAL

Not need any hardware settings, only send via USB to serial line ascii characters in preconfigured baudrate.

X,YYYYYYY\n

• X - band output in range 0-14, if activate BCD output range is 0-10 because 11-14 reserved for BCD. 0 (zero) = no output will be turned on.
• YYYYYYY - frequency in Hz - has no effect on the output relays, used if any CIV/CAT outputs activated.

ICOM CIV

Input worked in sniff mode (data over one wire - RXD). This means that it is necessary to provide, transmit frequency of TRX to serial line

• enabled CI-V transceive in TRX menu settings
• comunicate TRX with other device or software (for example logbook with CAT support)

Activate uncomment line

#define ICOM_CIV

Requires baud rate and CIV address in setting section of source code

#define SERBAUD      9600    // [baud] Serial port in/out baudrate
#define CIV_ADRESS   0x56    // HEX Icom adress (0x is prefix)

In icom_civ.h file you can set rules to select individual output relays, with a resolution of one Hz.

KENWOOD CAT

Input worked in sniff mode (data over one wire - RXD). This means that it is necessary to provide, transmit frequency of TRX to serial line

• comunicate TRX with other device or software (for example logbook with CAT support)
• activate function Frequency request which utilizes data output TXD, and prevent the use of any from CAT/CIV output.

Activate uncomment line

#define KENWOOD_PC

Requires baud rate in setting section of source code

#define SERBAUD      9600    // [baud] Serial port in/out baudrate
// #define WATCHDOG       10  // [sec] determines the time, after which the all relay OFF, if missed next input data - uncomment for the enabled
// #define REQUEST            // use TXD output for sending frequency request (Kenwood PC, Yaesu CAT)

You can also use functions

• WATCHDOG - determines the time, after which the all relay OFF, if missed next input data
