Hi Tom & David
Wow!
This algorithm (tune2.c) works very well on my ATU100/1000! It achieves good tunes on my three test bands 40m/60m/80m, as good or better than my most recent algorithm (recently posted),? and certainly better than David's vsn 3.2!.
What frequency was used to generate the data embedded in your tune2.c example?? My system has automatic access to the tx frequency because my transceiver is an sdr (Redpitaya) and that connects to the ATU via I2C.? So the options are endless.
Thanks for sharing this.
