Remi F1MQJ has modified the manufacturer’s v4.3 original firmware (published on may 23 2018) to include communication with KD8CEC memory manager.
This could be very useful for those wanting to stick with the HF Signals latest firmware, while making it easier to view or update initialisation settings, such as calibration of frequency or setting the BFO injection point, in the original firmware.
Modifications are the same as those described by Ian KD8CEC here but are adapted to the HF Signals V4.3 original firmware.
The file removes all text after .ino in your firmware directory replacing the original ubitx_cat.ino file.
