USB Control Cable for Amateur Radio

This 1.5 m cable connects a PC USB port to a radio 6.5 mm key jack using a CH340 USB chip. It lets a Windows XP, 7 or 8 computer send Morse code automatically at up to 50 WPM by triggering the DTR line on the COM port.

For operators automating CW from a PC

Suits hams who want software-driven Morse on ICOM IC series rigs with a 6.5 mm key port. Not for stations that lack this jack, need a different connector size, or require Mac or Linux driver support not mentioned in the data.

The 6.5 mm key-port interface decides compatibility

The cable only works with radios that present a 6.5 mm CW key socket wired for DTR keying. Verify your transceiver has this exact port before purchase; other connector types or keying methods will not function with this cable.

Questions about this item

Does the 1.5m cable or the CH340 chip require any periodic replacement?

The cable uses a fixed USB-A plug and a 6.5mm key jack with pressed-film connectors; no replaceable parts or service intervals are involved.

What limits continuous Morse transmission at 50 WPM over the USB-COM DTR trigger?

The CH340 USB chip handles the serial signalling, so the practical limit is the host PC's CPU load and the radio's own keying circuitry, not the cable itself.

How much heat or noise does the CH340 chip produce when the cable runs all day?

The CH340 draws only USB bus power (5 V, low current), runs silently and stays barely warm during extended CW sessions.
