Sub 300 Mhz remote not compatible?

Hi there guys, I’m using a very old remote system which is 30.875 MHz by spec sheet, which I can’t make to work on my flipper. Is it because flipper can use only signal higher than 300 Mhz, right? It can’t be fixed without a GPIO card, right? Thanks for the answers.

Yes, you are correct.

The very same (BFT T02 30.875Mhz) !
First try with my Flipper, first fail :frowning:

Hi, do you know any external module that make the flipper works with those frequencies ? I need it for 26,995 MHz remote control
