Bitx40v3 CAT Control firmware?

Sean W7SKD
 

I have a Bitx40v3 that hasnt been getting much use since I got my ubitx.  I have been thinking about using it for digital modes, but before I do, I need to get firmware on it that will support CAT control.

The ideal situation would be if there was firmware to be found that supported CAT on the USB interface the same way as Ian Lee's CEC firmware for the ubitx.  I have poked around and read through a few of the versions on github and havent found it, so....is there a version of Bitx40v3 firmware out there that supports CAT on the USB interface?

I am a programmer, so I COULD hack together something of a mashup of the bitx40 and ubitx (cec) if it came to it, but looking to see if someone has already done so

Thanks!

Just take the uBitX software and hack it up accordingly into the BitX40.....

Just curious why CAT control is seen as a requirement, When I started with PSK31 I was using an older rig and the only connection to a computer was via a SignaLink that provided audio in/out and PTT derived from a VOX circuit in the SignaLink. Others keyed the rig with some other output line from the computer off a serial port. Almost all the digital modes (save RTTY) were on "fixed" frequencies with tuning done by just varying the tones supplied/received in the audio passband of that frequency. Logging was easy since the frequency never changed. So what is the value of CAT control?

Hi =Vic=

It's much the same as VOX or semi-break-in or full QSK. It's a personal requirement driven by personal preferences. In my experience each and every ham is at least a little bit different from every other. Some of the differences are quite a contrast! I don't use CAT because none of my radios have ever cooperated with a computer but now I have one that will. I will eventually get around to trying it. Maybe I will discover that I can't live without CAT :) I tried FT-8 and rejected it out of hand. But I also tried CW and I still like it:) I even enjoy SSB and PSK-31 of all strange things. Have =you= tried CAT? If you did then you will be able to tell us why you do or do not like it:) The rest of us are on our recognizance.

Why cat?  Well, partly it’s because that’s how I’m controlling the ubitx on digital modes, so there is an element of commonality. Also, I don’t have a signalink or equivalent, and am using a modern pc without serial ports, so usb cat to the raduino is the lowest cost route.
