USB C to The K3's RS232?

Greetings Wise and Powerful Reflector,

I tried to get CAT control from WXJT-X via a USB C port > USB C to USB 2.0 adapter > Elecraft’s USB 2.0 to RS 232 cable > K3 with no joy.

The computer is a MacBook Pro running Catalina 10.15.4

Is anybody doing this?

TIA,
73 de Eric, KG6MZS

Re: USB C to The K3's RS232?

Yes. It works quite well.

I have several USB-C to USB 3.0 adapters, including the Apple ones that I use. Plugged into one of these I have a real FTDI USB to Serial adapter which talks nicely with the Mac.
For my K3S, I simply plug the USB cable into the K3S’s USB jack and get both serial control and sound for WSJT-X.

So yes, it does work very well. Make sure you are using a serial adapter with an DTDI interface, and do not load any drivers for the port. The FTDI drivers are build into macOS.
Also, set WSJT-X to use the same data rate as the K3, which defaults to 38400 bps.

73!

Hi Jack,

Thanks for the reply. My set up in a little more complicated with the K3’s RS 232 port and not a USB port like on your K3S

So I have to use the line in/line out for the audio via an outboard Focusrite Scarlett 2i2 sound card.

Re: USB C to The K3's RS232?

I’m embarrassed to say that I don’t honestly remember. I thought I bought it when I started doing PSK in 2007 or so, and I thought I bought it from Elecraft, but I’m not sure.

There are no marking on it. I could eMail you a photo, but that probably wouldn’t do any good.

It’s worked fine out of a 2009 computer with USB 2.0 ports for years.

Thanks again for taking time to help
