Title: USB CW interface
Post by: AF5CC on March 19, 2013, 06:58:59 AM
Is there a simple, inexpensive interface to go between a USB port and the CW jack on a radio to allow contest logging programs like N1MM and NA to be used as a memory keyer?

Is a $79 WKUSB-HV kit too expensive? ( (

I have the USB Winkeyer -- it's the "Cadillac" solution to the problem.  And it's not hard to put together, if you can solder.  No surface-mount soldering is required.

You can get a USB-to-serial adapter, and a kit from W3YY:

If you're using Windows 7 (or 8, I suspect), get an adapter based on the FTDI chip, not a Prolific chip.  Check eBay for sources.

Now, somebody will supply a source for the single-transistor circuit that substitutes for the W3YY kit . . .

Another vote for Winkeyer USB.

 I have been using it with N1MM & Logger32 for the past few years now. After a minor installation problem, (conflicting ports) it has been spitting out the dits & dahs without any hiccups at all.

WinKey USB is the best, but if you want a more affordable solution, a USB-RS232 adapter and a simple circuit with only one transistor and one resistor works just fine, I build one myself and have used it for several months with no problems at all!

With WinKey you can send CW from PC/MAC or a paddle, and the speed is the same, you can do that with the simple circuit I mentioned above but the speed is set separately and most of the time they are not the same, sometimes when I first send from PC/MAC then use paddle to send something else, the other station will get confused because they think that's another station! HIHI. So I'm considering build a WinKey someday.

Look at the radio arena website -  For years, I have used one of his interface cables which cost less than 25USD (16GBP).  It needs a Prolific driver which is a little tricky because the driver from the Prolific website doesn't work with Windows 7.  I downloaded a Vista driver after a little research and searching the web.  It works great. I use the CWType software.
