I used to use RUS, until I discovered that the attack (invalid to valid transition) is significantly delayed, around 50 ms. CAS does not have this delay, & I find that the fast squelch performance is better because the chopping is less pronounced. This is because even though the squelch does briefly close on signal nulls during mobile flutter, it opens much faster, so the chopping isn't as noticeable. I still use Micor squelch boards in all my UHF MVPs & Mastr II RXs, but I don't bother on the VHF radios as I find the Mastr II squelch works well enough. Bob NO6B
