i have one of these installed in one of my madisons, and i like it.
i do wish he would make it more modular, like providing options that can be used with tactile switches. a channel jump option would be nice.
it would also be great if you could set your own band edges.
i don't need mine to go all the way up to 28.755 but you are limited to the VCO scan function to set the band edges.
the encoders he uses are very cheap and won't last. also the shaft length is wrong for some radios like my madison.
i had to go with another encoder, and the way he sets his error band for this control is too tight so it can get a bit glitchy when turning the channels up too fast.
all in all though, i do like having it in the radio.
