The SG-231 SmartunerTM is a new addition expanding the famous family of SGC couplers, the SG-230, SG-230PRO and SG-235. Works with any HF SSB transceiver and low-band VHF (i.e. TS-50, FT-900, DX-77, IC-706 and other 100 watt transceivers)

SG-231 is a further refinement in the ability to microtune ANY radio and ANY antenna with more discrete tuning components and sophistocated microprocessor tuning power. The traditional * (pi) network is retained with a combination of more than 4 million steps compared to the SG-230 with a half million steps.
