I have an ANC-4. It is a MASSIVE key click generator if you put it 
inline with your transmitter. Other than that it works. :)  This is 
caused by the circuit that detects when you're transmitting and does 
T/R switching to bypass the unit. You can get around this by putting 
it in the receive loop only (that is, so that it never sees the 
transmitted power). I have not seen the other two units.
