Im not a spektrum guy but here is what I could find. That reciever might be using a protocol designed for spektrum satelite but people in this forum post couldn't verify that for sure.
This video breaks down the different protocols between flight controllers and recievers.
It looks like there is just a compatibility issue between the F4 FCs and spectrum receivers. https://github.com/betaflight/betaflight/issues/3677
Since I'm not used to spektrum I can't be much help.
Here is the cheapest alternative I can recommend
About $70 on amazon.
