Winbox not showing Frequeny offset menu item

Hi

I am new to RouterOS.

I am using RB433AH board and winbox to configure it. The routerOS version is v5.26. Winbox is now showing frequency offset menu item in the wireless interface part. I can see Frequency mode, etc but not the frequency offset field.

Please help.

Thanks

Open a terminal

interface wireless set wlan1 frequency-offset=xxx

Thanks a lot Oldman. It worked.

BTW, why dont I see the frequency-offset submenu in winbox wireless interface menu?

I’m running 5.25 on most of my hardware and don’t see the option in winbox.
