## How to add new SubGHz frequencies
#### CC1101 Frequency range specs: 300-348 MHz, 386-464 MHz, and 778-928 MHz
Edit user settings file located on your microSD card - `subghz/assets/setting_user`
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,
418000000,
433075000, /* LPD433 first */
433420000,
433920000 /* LPD433 mid */
434420000,
434775000, /* LPD433 last channels */
438900000,
/* 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`<br>
But remember! You should keep it as small as possible, or hopper functionality would be useless!<br>
If `#Add_standard_frequencies: true` is not changed<br>
Your frequencies will be added after default ones
### Default hopper list
```
310000000,
315000000,
318000000,
390000000,
433920000,
868350000,
```
