>I'd love to do it TX side with a couple of op-amps though :)
All of this is TX side. There are a couple of oddball mixing RXs but that's not common.
Initially it was done with op-amps! My dad did some early modifications in some non-mixing radios for the makeshift F3B national team to take to the world championships a long time ago. These days it's just much much easier and more flexible to do it in software.
