Spider Keyer (Arduino Nano CW Keyer)  
  Version 2.0

Why Spider Keyer?

(1) Unlike WinKeyer (2) Unlike K3NG

Spider Keyer was mainly developed as a companion to HamRacer logging software.

Spider Keyer enables you to:

  • Send CW from a PC (communicate both ways with the controlling SW)
  • Send CW manually, iambic, using the paddles (both Curtis-A and Curtis-B modes)
  • Set up basic properties such as lead-time, tail-time, hang-time, etc
  • Set a side-tone separately for automatic and manual sending
