[Elecraft] another contesting how-to question

Tue Feb 14 20:19:17 EST 2012

I had RTTY on the brain Fred! 

I bought a used K3 a while back and he included your book with it. It helped with some settings I was struggling with, I had forgot I had it until your post.

GL this weekend. I'll be on a bit, but not FT. Taking my wife out to a play Saturday night...

Cheers,
Julius

Actually, you don't need a keying interface. The K3 does it all. And I, 
too, have had no problem keying the K3 from N1MM without a Winkey. 

In the Config menu, go to PTT-KEY. 
Rotate VFO A to choose OFF-DTR. (You can also choose any combination of 
DTR and RTS from the serial port to control PTT and Keying. See Table 
3-12 in the KE7X book, if you have it). OFF-DTR means that there is no 
PTT control and the K3 will expect a keying signal on the serial port 
DTR signal. 
In N1MM (I can't speak for other programs), go to the 
CONFIGURER->HARDWARE and click the CW/Other Details box for the serial 
port you connected to the K3. 
Click on SET and make DTR be CW. 

That's it. The serial port will be the radio control interface and also 
will key the radio when N1MM sends CW. No LPT or any other keying 
interface needed. 

I haven't done it (no SSB contesting experience) but I suspect that the 
PTT capability can be use to key the radio when N1MM is being a voice 
keyer. 

DX guys, see you this weekend :-)

Tim, 

Winkeyer is a great piece of equipment and was needed for the K2 after 
some changes to N1MM years back, due to timing issues. 

For the K3, you do not "need" Winkeyer at all, and we're talking up to 
40 WPM. You do need two ports. You can use the LPT port or  USB to 
Serial adapter from your computer, or there are serial add-on cards to 
be had. N1MM generates CW. 

You will need to build/buy a very simple serial port keying interface to 
key the K3 from the program. It is in the N1MM start document, and I see 
there are a couple folks who have built little boards for CW/PTT/FSK for 
this purpose. 

Winkeyer may be a cost effective option, if you don't have a usable 
second port option. 

I traded my last built Winkeyer for an un-built kit and some aluminum 
tubing. The keyer is still unbuilt. The aluminum is in 40M vertical form 
;o) 

Check the getting started with N1MM document, it explains a lot of this 
in easy to read details. One of the better start=up guides I've seen... 

GL in ARRL DX CW!
