Available from Amazon

Has excellent reviews, including Linux users.

For CW/FSK interface, flrig and/or fldigi can directly interface to this device without needing a WinKeyer.




CW Keyer

Open the keyer dialog

with the main dialog menu item "Keyer/CW keyer"

  • WPM slider selects the keyer speed
  • Clear - clears the text in the transmit buffer
  • transmit text will marquee to the left as each character is transmitted
  • Send/Pause button toggles sending text.
  • macro buttons / function keys load transmit buffer with canned message
    • left click to load macro contents into transmit buffer
    • control left click to open macro editor dialog
  • the transmit text buffer must have keyboard focus for character entry. left click on the entry area to gain keyboard focus.

Tip for the function / macro buttons:

Control-left-click opens:

A CQ macro with start/stop (ptt enable/disable):

[CQ CQ DE W1HKJ K]

Prosign characters can be configured by the user. The macros and prosign assignments are save in the transceiver prefs file.

Config opens:

The DTR/RTS port can be either

  • shared with the CAT port
  • shared with the SEP port
  • shared with the AUX port
  • a unique serial port configured on this dialog

Select either DTR or RTS for the keyline as required by h/w.

Calibrate button sends standard "PARIS " word, WPM times. Program measures actual time to transmit and sets compensation value. WPM Comp msec can be adjusted by user.

Xcvr comp msec is used to increase or decrease each key down interval by the specified time interval.

7300 CW DTR/RTS keying @ 24 WPM

The effect of a -2 msec Xcvr comp adjustment is clearly seen and easily heard.
It is especially important to correct weight errors introduced by the transceiver keying circuits when operating QRQ (high speed CW). At 80 wpm 2 msec is a significant part of the target dit interval of 15 msec.

PTT delay is in milliseconds. Enter a non-zero value to enable a delay between the PTT-on and the first CW keyline closure. The same delay will be applied to the last CW keyline closure and PTT-off.

The CW keyer is specifically designed to work with a DTR/RTS keyline to emulate the closure of a CW key. Several transceivers have this capability built in to the hardware. Some expose a separate keying port (FT-991A) and some share the CAT serial port (IC-7300). A simple DTR/RTS keying circuit can also provide the h/w interface. This one provides galvanic isolation:

Inexpensive USB serial-to-CW-keyline devices are available from internet vendors. (see above)

This is the second time I have been bitten by this problem. K1EL WinKeyer has been switched from FTDI to CH340.?? That CH340 does not work well with other USB adapters.? Now I am looking for an older used Winkey 3 to replace the new one which is giving my remote station users trouble, and have been in contact with Carl, N4PY who has also said good words about FTDI.? I just bought two more cables which sellers SAID they had FTDI chips but Linux reports them as CH340. and refuses to accept them at all.? They are what this is all about!

One thing I can do now, is take a laptop with me with Linux on it, plug it in and see what chip it has, but I live in the middle of nowhere.? I have to drive 1200 miles to get to civilization.? I love living in the Yukon and wont change that for anything, but often have to find ways around the distance issues.? If you see or hear of anyone who is selling his keyer with a pre-340 chip k1EL chip or keyer please let me know, and also I need to come up with a good pair of
USB-232cables or adapters for my Omni-VII's here.
