just out of curiosity, what's the bandwidth of the typical ALC  
circuit?  It needs to clip on voice peaks, so, I'd think in the  
milliseconds sort of time frame, implying a 1 kHz sort of bandwidth.   
I haven't figured it out from the schematic yet on my IC7000, but it's  
an all analog circuit with direct feedback to the Tx IF drive amplifier.

Since FlexWire uses I2C (as I recall), which is no ball of fire, speed  
wise (although 100 kbps is easily doable, with 10kilosamples/sec  
possible without working too hard) that might set a limit on the  
performance of the ALC logic, if you're doing a simple "voltage in to  
set gain" strategy.
