Operation in the 135 kHz Band
Since the Technical Regulations Conformity Certification of the transceiver is invalid for operation in the
135 kHz band, you need to make a separate application for certification to work this band.
• Higher-level knowledge and skills are required to connect external equipment to the transceiver.
• If you use external equipment, be fully aware of the connector specifications, possible loop

For use of the legendary slope tuning and WIDTH/SHIFT functions incorporated in successive
Kenwood HF transceivers, TS-590S stores the status of two filters (FILTER A and FILTER B) set for
each type of signal. Hence, you can easily switch between the filters with a single touch of a button.

As an example, store the setting of a wide IF filter and narrow IF filter in FILTER A and FILTER B
respectively. When you look for a station for a contact, use the wider FILTER A and once you have
started a QSO, switch to the narrower FILTER B, with a touch of a button, to be able to receive the
target signal only .

This filter switchover with a single action is based on the way the NAR function was used in the days
when analog IF filters were used. Continuously, variable bandwidth is convenient in the sense that
you can adjust it freely to whatever value you choose, but you may have difficulty operating in a
timely manner in a contest or similar because it does not allow a jump to a certain value
instantaneously, Therefore, we considered introducing a mechanism equivalent to the previous NAR
function, but we were swayed by the opinion that a user wants to operate with normal bandwidth
usually, yet still maintain the to switch to a wider bandwidth when it is required. Consequently, to
satisfy both needs, we have devised a system to store settings freely.
