The new SG-239 fits the coupler requirement of the many low cost HF transceivers on the market, including among others, Scout, Yaesu FT-817, Kenwood TS-50, Icom IC-706, and the K2 kit. Of course, the SG-239 is ideal with the legendary SG-2020 transmitter.

Performance features of the SG-239 are far ahead of its low price tag. The unit will work with silent receiver tuning or within the range of 1.5 to 200 watts with a high power transceiver. It has 170 memory bins, with fast, accurate tuning via independent sensors, including VSWR, phase, magnitude, low impedance, and forward sensing. Other couplers only sense the VSWR for a proper match the SG-239 does it all and does it fast. And, if you recall the tuning setting from memory, tuning is even faster.

The SG-239 utilizes the respected technology of the very popular SGC Smartuners. This new low cost and high performance product will offer radio amateurs an opportunity to achieve increased levels of operation with any HF equipment.
