Chris,
There is code in the uBitx software, both from the original and KD8CEC code.? I found the following:
//original code with modified by kd8cec
? if (usbCarrier > 12010000l || usbCarrier < 11990000l)
? ? usbCarrier = 11997000l;
?
? if (cwmCarrier > 12010000l || cwmCarrier < 11990000l)
? ? cwmCarrier = 11997000l;
My suggestion is to find these lines in the ubitx_20.ino source file and modify to allow for the range that your rig will need. (note, you will need to download the entire ubitx-1.1.zip from KD8CEC repository)? You can find a link to the files on the Hamskey.com web page.? Also on Github:??in the??(zip) folder
Hope that helps
