Hi Alan,

?

Nice work! Question, how do you determine the step sizes per band?

?

For example, there are 10 tuning memories per antenna per band up to 4 antennas per band. On 80 meters I use 50 kHz steps starting at 3.525 MHz and the 10th step winds up at 3.975 MHz.

On smaller bands like 17 meters you could probably accomplish tuning in 2 to 3 memories with smaller step sizes. Just curious how you deal with that.

Using the WO2X Tuner Genius Flow as the TCP stream and polling source, I built a SVG based Flow that will sequence the Tuner Genius through a range of selectable frequency range, and step width, to "Teach" the Tuner Genius the tune solution for each frequency.

Results are displayed in a SVG bar chart. ?Here is a screenshot of the results of teaching my Tuner Genius the solutions for a G5RV antenna, across the 40 M band, ten steps. ?Also, attached is a video of the Tuner Genius "Learning".



Because the Tuner Genius only allows three TCP connections, I used Dave's Tuner Genius flow to move the TCP stream to my flow. ?In my case, I used MQTT nodes, but you could substitute "Link" nodes too.

Here are the required connections:
