Hi.
Today my Flipper is just arrived and I want to open my Garage door with him.
Is it possible that the old Sender have a frequenz at
26.985 MHz ?
I can’t read the modulation.

The lowest supported frequency is 300mhz, our radio chip can’t go lower
So, unfortunately, no 
Same here with a 30.875 MHz remote.
So the only way is an additional radio chip (on a module?)?
Yep
A HackRF with Portapack could read it, but it’s the size of a large cell phone, and isn’t nearly as convenient as the Flipper Zero. The HackRF One is capable of receiving and transmitting on a frequency range of 1 MHz to 6 GHz with maximum output power of up to 15 dBm depending on the band.
The latest firmware is Mayhem.
