The Kenwood TS-120S VFO-120 is a versatile transceiver that enhances the operator's ability to engage in split-frequency operations. This feature is particularly beneficial for chasing DX, net monitoring, and identifying precise frequencies while maintaining the original frequency. This feature is essential for amateur radio enthusiasts who often need to communicate on different frequencies without losing their primary channel. The design caters to operators' needs, requiring flexibility and efficiency in their communications.

A notable component of the Kenwood TS-120S is the VFO-120, which includes a T.F. SET switch. This switch is crucial as it prevents accidental transmission on the original frequency during split-frequency operation, ensuring operators can quickly and accurately set their transmit frequency without interference. Additionally, LED indicators allow users to monitor VFO functions easily, providing a clear and immediate visual reference for operational status.

The Kenwood TS-120S's compact dimensions, measuring 4.9 x 3.8 x 9.4 inches and weighing 5.5 lbs (180x133x287mm, 8.9 kg), make it a portable option for operators. Its lightweight and small footprint facilitate easy transport and setup, making it an ideal choice for home stations and field operations. The TS-120s provide power for the unit, ensuring reliable performance during extended use.
