True Keyed CW

  • In addition to the PTT keying circuit there is a fully isolated CW/FSK keying output for direct keying of your rig's CW or FSK jack for keyboard CW and RTTY software
  • Input for control of the additional fully isolated CW/FSK keying circuit as well as the PTT circuit is jumper selectable between serial port control pins: RTS, DTR, and TXD

Mic/Keying/Audio Flexibility

  • Front panel mounted transmit power level knob makes it easy to adjust transmit levels on the fly without having to make changes in software sound levels
  • No extra manual switches needed, two DPDT relays for true automatic operation unlike other sound card interfaces
  • Simpler operation than the other brands, you never have to remember to push un-needed switches to make your station work
  • PTT override and interrupt enables mic to override the computer or stop the computer program, perfect for contesting or SSTV operation
  • Rear panel RCA PTT switch / foot switch jack enables the PPT override and interrupt
  • Internal diagnostic RTS, DTR and TXD LEDs show at a glance what the serial port is doing
  • Properly matched and RF suppressed audio for your radio
  • Fully isolated transmit audio and PTT keying, unlike other interfaces that have little or no isolation
