Hi there,

I am about to get a new SunSDR2DX and I am really looking forward to operating with it.

At moment I have an Elecraft K3 and with it I give CW lessons to Spanish hams using a SO2R mini device (is Winkey compatible) and setup is quite easy due to features of the K3, a jack to a paddle and another jack to a vertical key or a device like the one I have here.

However, with the SunSDR2DX we only have one jack for CW what should be configured as a paddle or a manual key. I know I can add another paddle connected to a RS232 socket and in fact I have such device with me.

I wonder to know if using the software for the SunSDR2DX would be possible to send text messages and output it in CW ?

Have a nice weekend and best 73.

You can send CW using the TCI protocol.
Either directly from a websocket plugin in i.e chrome or using a third party software.

For windows you can use: iw7dmh.jimdofree.com/sunsdr2-pro-pages/tci-macro/
For "all" OS: github.com/ftl/tci or github.com/LA3QMA/TCIMacro

Hello Kai,

tks indeed for your replay.

Well, software that you pointed me out is the answer to my request, however, forgot to say that I am running a Mac computer. Is there any possibility to add Mac OS to your software ?

Best 73 and have a nice weekend.

Hi Kai,

I have downloaded your application to my Mac computer, it seems to work well but of course without a SunSDR2DX radio I am not able to send out any text.

So, just a few questions:

1) During my CW lessons I have to pause sending CW time to time, it seems that your app has a TX button, or it seems so, can it be used to pause the CW transmission?

2) is there any limit in characters to send a free text?

Duing this Monday I will test your software.

Best 73.
