You won't notice much difference in a wide filter greater than 1000hz, but with
narrower filters tuning to the exact zero beat will give the strongest signal to
the RX, especially if you reduce the filter's band width with DSP to 100hz or
less.  When you get down that narrow you may lose the signal if you're not right
on it.

I'm speaking from experience.  I have no scientific proof of this.  I could be
wrong in a scientific regard, but that's what works best for me.

How do you like your Alpha 99?
