As reported by many others in earlier threads, the calibration routine Ashhar's raduino sketch v1.01 on Github isn't working. There were two issues: 1. the correction factor is not calculated

Re: uBITX - A reboot of the old BITX
Ashhar, I for one (among many, I suspect) would jump at the chance to purchase a uBitx kit from you / HFSigs.com. Please, please develop the uBitx into a kit! Thanks again for the Bitx xcvrs! -
