[Dx4win] The better interface - CW

[K9RBorowski]

I've been using the simple serial interface as described in the "DX4WIN/Docs/Usrguide.pdf" file for the past 12 years with never a problem. I never tried the parallel version because many complained about the stutter that one exhibited for lots of users, even back in the mid 90's, running under Windows 95. Over time, I have used Windows 95, Windows 98, Windows 2000 Pro, and Windows XP Pro without any hardware changes required for DX4WIN or CW keying. It works on the same serial port as the rig control if you so desire too. My rig interface has an extra RCA jack I installed that is connected via a "T" connector to the key port of both my transceivers and the output of the 30 year old MFJ grandmaster. This allows me to send with the paddle and the Keyer, type on the DX4WIN keyboard, or use the DX4WIN keyer memories or the MFJ Grandmaster memories. When I added the second transceiver a number of years back, I added a small 4 pin opto-isolator to the second rig key input to be safe. Your setup may just require a tap into your serial cable to get to the DTR pin and Ground Pin and a general purpose NPN transistor, like a 2N2222 and you'll be ready to contest tomorrow!  73, Rog-K9RB

  Hi everyone
  I want to buy an interface to use with DX4WIN on CW mode. What is the better one?
  Please, help me to chose one, but consider:

  I Notebbok has only USB and my mainly use will be CW. Price is very important because taxes in Brasil are very strong.

  Thanks. 73 Mac PT2CC
