My MicroHam microKeyer III + Numeric Keypad + Cable is available for sale. It is still under warranty, purchased from Wimo, Sept 2021. I no longer need it since upgrading to my new 890S. :)

This interface works with pretty much all radios. It offers several functions over a single USB cable connected to a Windows, Mac, or a Linux PC:

• Audio in/out interface for digital modes, using 24 bit resolution (higher SNR than 16 bit), with lots of level customisation and adjustments, supporting two channels for radios with dual receivers
• CW keying using the original K1EL WinKeyer chip
• RTTY FSK keying using on-board UART, works with MMTTY, DXLog, N1MM+ etc without additional cables
• CAT control over RS-232, Icom CI-V, TTL etc in older generation radios that do not have USB
• Digital Voice Keyer, DVK, for both phone and CW, great in contests :)
• Automatic microphone selection
• Timing control over a linear amp
• Option to use a foot switch
• Flexible, stable control over serial/COM port assignments to simultaneously running multiple programs, using microHam USB Device Router (Windows) or mhuxd Router (Linux) and similar functionality on macOS using RumLogNG.

The cable that I have is for Yaesu FT-450, FT-450D, FT-991, and FTDX-10. It would need to have connectors changed to suit other radios, see attached diagram, or a new model-specific cable https://microham.com/contents/en-us/d138.html can be purchased from https://microham.com/contents/en-us/d1210.html or Wimo etc.

New prices are: MicroKeyer III €399, Numeric Keypad €25, Cable €109. Total €533.

I would like to sell the lot for €320 or €290 without the cable.

I can also sell a RadioSport headset cable for the microKeyer, €60 (€94 new).

Happy to ship with AnPost registered, or meet in person in Dublin or near Bray.
