Got it hooked up today. Conversion was super easy. Did have to use tweezers to move the jumper from 1 and 2 to 2 and 3.
The receive noise reduction absolutely works. I finally settled on setting 3 because at setting 5 the voices did not sound natural. At setting 3 it still works good. It even knocks down annoying solar panel noise.
Does anybody know what noise reduction on transmit actually does? It's default off, so I did not change it.
Channel rejection is pretty dang good in my opinion compared to a Stryker 447HPC2 and a Lincoln V2. Redeye Crow lives about six miles away from me, and he was on the bowl pegging me at 60 db. He was not bothering me at all on my home channel 31.
