[Elecraft] N1MM config questions

Check and see if the logging software will send  a command to the radio to 
go into transmit mode.  Then you don't have to  worry about RTS, DTR, 
transistor switches, special wiring or any of that  stuff.

Hi, Steve!

N1MM  can activate the PTT and CW keying lines, but you'll need to fashion  
or
acquire a single-transistor switch (see  http://aa5au.com/rttyinterface.html
for examples) for the DTR and/or RTS  lines.  I'd create two switches, one
for PTT and another for the CW  line.  W3YY also makes a cute little board
for this,  http://www.w3yy.com/fsk.htm. The N1MM site also describes this  
at
http://pages.cthome.net/n1mm/html/English/Interfacing.htm.

If  you're using a USB to Serial adapter for your RS-232 keying interface,
there  may be some "gotchas" depending on your USB to Serial Adapter. I'm  
not
up-to-date on this, but plan to spend a little time with your  breadboard
version before committing to use this as your only  technique.

Some users have reported CW "stuttering" with some computer OS  versions,
which is why a WinKey device is so popular with contesters.   Sometimes the
CW stuttering doesn't occur until late into the contest, when  there's a lot
of CPU or disk activity when you log a new QSO. Minimizing the  disk I/O of
other programs is essential if you're trying to send quality CW  from a
computer with a time-sharing OS (e.g., all versions of Windows).   Others
have had no trouble at all.  

Your wife insisted that you  acquire a K3?  What a gem she must be!

Subject: [Elecraft] N1MM config questions

My  lovely bride of almost 32 years has recently insisted that I buy a K3 
for
my  belated birthday present, so I did (what a woman). I am starting with  
the
basic kit that includes the 100 watt amp and 2.8Khz and 400Hz Inrad 8  pole
filters. That is it. Building the kit was a lot of fun and #3979 is  happily
on the air.

So far I have serial communications with N1MM  Logger so I can change
frequencies from the TNC or bandmap window. I am  looking for sage advice
with respect to keying and audio. I do have a  RIGblaster plus here but can 
I
key the rig from the serial cable? So far I  have N1MM set for the proper
serial port talking to the K3 at  38400-N-8-1-1-DTR and RTS Always On. If I
can key it with this cable, I could  toss the RIGblaster aside and try some
of the recent audio hints I have read  here in the last day or so, but 
please
advise on this too if you  can.

I know I am still pretty unfamiliar with the rig but I hope to get  on any
way this weekend when I can. It¹s nice to be part of this new family.  
Thanks
for reading this and thanks in advance!
