[Elecraft] K3S: Need SO2R Antenna Switch Recommendations

[RVZ]

 My pair of K3S radios are in need of a 2x8 Antenna Switch for SO2R operation.  I'd like the SO2R Antenna Switch to have a built-in band decoder so the Band Data output from the  K3's ACC jack will do the switching.  I don't want an external Band Decoding unit for multiple reasons. So far, the only SO2R Antenna Switch I know of that has a built-in Band Decoder is the FLEX 2x8 Antenna Genius.  Please advise if there are any others? Thanks!  Dick- K9OM
