Here's a handy link for that:
I really wish someone would sell a kit or preassembled tracker for us lazy people.
What'd be more ideal is if someone ran a kitting business for the open source satnogs rotator. https://wiki.satnogs.org/SatNOGS_Rotator_v3
Buying in bulk, one could probably get the price down to $200 and still keep a profit, but the volume would be so low that it's probably not worth the time and effort.
I've thought about doing this, ran some math, and that's the conclusion I came to.
My gut feel is that SatNOGS would be easier end-to-end (and probably easier to repair and upgrade if necessary).
But yes, I should consider the Yaesu.
This is more recent.
