Okay so what's the point of this post? Are you trying to sale us on Jeti radios? Or tell us to pay attention to signals loss? Most everyone I know range checks their models and can easily see signal strength after each flights.
Im not sure what equipment folks are using with poor signal quality but the only time I have seen any of my signal drop was a receiver that would sit about 5% below the other receiver so even in the primary slot the receiver was pushed to the secondary.
