[Elecraft] K4 CAT over IP with N1MM+

[Gerry Hull]

I operate remote a lot.  I have not had the opportunity to try the K4
remote, because
there is no client yet.

However, it is possible, I believe, to operate the K4 using N1MM+ only.

In doing some tests, I have successfully controlled SmartSDR Mac using
N1MM+.  It works
beautifully.

I'd encourage those with K4's to try this solution and let me know.

If you want to see it in action, Here's a very short video of EA3HSO,
running SmartSDR for Mac, sending CW from N1MM+ in a Windows Virtual
Machine on Mac.

So, what is the magic sauce?

There are multiple FREE products that map a virtual serial port to a TCP
connection,either as a server or as a client.

https://www.netburner.com/virtual-com-port/

https://www.hw-group.com/software/hw-vsp3-virtual-serial-port

I use the netburner version.

When you run the application, you create 1-to-N com port to TCP mappings.

You would connect to the K4 using this software.  This could be on the LAN,
or over the Internet using Port Forwarding.

Install the Netburner or HW-group software on your Windows PC.  The steps
are pretty much the same in either software. In the Netburner software, you
create a new virtual serial port, with a TCP CLIENT, connecting to the K4's
IP address and port.

Once you configure it, you will see the status in the software.

By the way, the NetBurner software runs as a service, so once configured,
it is always there when you boot Windows.

Start N1MM, and configure for K4 (at 38400 baud, though the speed does not
really matter.)

You should have CAT control.  It if does not come up directly, go to the
Bandmap and press on the red message at the top.

How does CW work?  If local, you are good.  This is for you guys to test.
I presume the K4 supports KY macros?

In N1MM, you use the CAT1ASC command. For example to call CQ,
{CAT1ASC KY CQ CQ DE *;}
(* is your call, ! is the call in the entry window.)

KY Macros have limitations on N1MM, but for most contesting and general
QSOs, it is fine.

So, K4 owners: give this a try.  It will allow remote before the K4 remote
is available.

Let me know your findings,
