5 SOFTWARE: ENHANCING OPERATING PLEASURE

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.

•If you use external equipment, be fully aware of the connector specifications, possible loop interference, and other relevant issues.
5.3Single Button Toggles IF Filters between A and B
For use of the legendary slope tuning and WIDTH/SHIFT functions incorporated in successive Kenwood HF transceivers,
Figure 5-3 [IF FIL] Key
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 .
Hints and Tips
“Is this filter switchover with a single touch of a button different from NAR?”
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.
