in this file you will find we already have extra frequencies added if you need your custom one, make sure it doesnt listed here

Default frequency list

    /* 300 - 348 */
    300000000,
    303875000,
    304250000,
    310000000,
    315000000,
    318000000,

    /* 387 - 464 */
    390000000,

    433075000, /* LPD433 first */

    /* 779 - 928 */
    868350000,
    915000000,
    925000000,

User frequencies added AFTER that default list! You need to continue until you reach the end of that list

If you want to disable default list and use ONLY user added frequecies from user settings file

Change that line #Add_standard_frequencies: true to Add_standard_frequencies: false

To add your own frequency to user list

Just add new line Frequency: 928000000 - where 928000000 is your frequency, keep it in that format! it should be 9 digits!

Hopper frequency list

To add new frequecy to hopper: add new line Hopper_frequency: 345000000
But remember! You should keep it as small as possible, or hopper functionality would be useless!
If #Add_standard_frequencies: true is not changed
Your frequencies will be added after default ones

Default hopper list

    310000000,
    315000000,
    318000000,
    390000000,
    433920000,
    868350000,
