Overall, TS-140S audio quality on every mod is reasonable even when using the standard microphone that comes with the Kenwood TS-140S. Modification is required to access MARS frequencies because the CPU is designed to only operate on Ham radio bands.

The included instruction manual will supply information about programming a custom mode.Like so many modern rigs, TS-140S transceivers can be modified easily for MARS frequencies. Users can program modes in all 31 memories. The product comes with 31 memories that complement two VFOs. Scan speed can be adjusted from the front panel, or memories can be scanned manually using the up and down buttons. Operators will also notice both band and memory scans.

Operating the two knobs of the TS-140S to transmit is simple to learn. There are two main knobs for tuning, which include variable frequency oscillator tuning control and a memory channel knob.

Similarly, Kenwood also supports 10 Hz read-outs in the front panel, which is useful for TS-140S operators as they don't need to open the rig to make internal modifications. In addition, information such as VFO, memory position, and RIT are shown in assortments of colors such as red, blue, and yellow. The receiver has superior dynamic range without filter reception restrictions while delivering excellent-quality voice transmissions.The TS-140S has a brightly lit, blue-colored digital frequency display panel, which offers a lot of information on one screen. This device has a modern touch as it also features adjustable scanning speed and an exceptional 500 kHz to 30 MHz broad coverage receiver. The split frequency is useful for 10-meter FM repeater operations. The transmitter has two VFOs that allow band split operation, called SSB and CW splits, which offers diversity to its audio capabilities. TS-140S can withstand background static, giving users a clear and continuous audio experience using a powerful radio antenna. In addition, a digital frequency display and lightweight design makes the device easy to operate and move with ease. The Kenwood TS-140S has handy bodywork where front-panel controls are laid out strategically.
