Anyone has success in running Sotabeams Laserbeam-Vari Filter controlled by the Arduino Nano as described on their website ? (https://www.sotabeams.co.uk/variable-bandwidth-filter-modules-ssb-cw/). I have problems with loading the KG4RUL Sketch up onto the generic Arduino Nano. Would appreciate any info incl. video on how successful you were with this sketch and how the final construction with the filter is working. The filter alone is just fine.
