I want to be able to run my V1 as the primary detector alongside another detector that can display Ka frequency *without* interfering with the V1's performance. I'll need the 2nd detector only for frequency display.
In this situation, am I only limited to a Belscort that is immune to spectre? (since they don't interfere with other detectors)
Or can I run a cheaper non-immune detector that displays frequency and not worry about it affecting the V1?
What is the most cost effective solution?
