• Opto Coupled push to talk circuit also eliminates ground loops and false triggering of your PTT lines.
• Integrated sound card interface just simplify work and connection to pc.
• High quality FR-4 double sided, solder masked, silk screened, Printed Circuit Board.
• Compatible with most modern ham radio transceivers.
• If you wish to not use the serial port for PTT, you can just use the audio channels and key your radio via VOX operation.
• Compatible with most USB to Serial port adapters for use on laptops and other computers that do not have serial ports.
