You might try experimenting with the value of R46 - it determines how 
fast the agc will track a varying signal. If it's a very high value, or 
is removed entirely, the agc couldn't track a varying signal at all - it 
would simply freeze until the end of the "hang" period.

There's a more detailed description by me of how the CorsairII agc 
circuitry works here:

By the way, I love the Corsair's hang agc and converted my OmniVI to 
something very similar! "Every man to his own" as they say!
