CHIP is a spread-spectrum PSKPhase-Shift Keying mode developed by Antonino Porcino IZ8BLY. There are two modes, CHIP64 and CHIP128. Both modes use 300 BdBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. and look and sound identical, but CHIP128 uses twice the spreading code length. CHIP64 runs at 37.5 bpsBits per second (bps), where CHIP 128 runs at 21.09 bpsBits per second (bps). As the names suggest, CHIP64 uses 64 chips and CHIP-128 uses 128 chips. Both use D-BPSKBinary Phase-Shift Keying (1 bit per symbol) at 300 chips/s.
