I recently just purchased a second hand Bel 975R off eBay for a very good price (AU$100). I have the Escort X50 which is an excellent all rounder, but not the best for multanovas and I was just going to experiment with installing the 975R and dedicating that to Ka narrowband to pick out those multanovas. The main reason I bought it was since it was so cheap and I just wanted to see what would happen.
I know two detectors are never supposed to be run at the same time, but that is for windshield mounted radar as it is easy for the radio waves to interfere.
But what about a dash mounted and a remote mounted radar? Would there be much interference between these two detectors??? If there are a lot of barriers between them in a car, would that be effective enough to protect each detector from the radiation from the other one?
