This is my theory:
I still think it might have something to do with the receiver type.
RX65 and original 8500 have this in common:
Radar Receiver / Detector Type
· Superheterodyne, GaAs FET VCO
X50 and STI have this in common:
Radar Receiver/Detector Type
· Superheterodyne, Varactor Tuned VCO
I can't wait to see the Ka performance on the STI. I hope the STI is better than the X50 with Ka.
Does anyone know the receiver type for the Bel Vector 985?
