Maybe what we need here is a tutorial on the K3 Noise Reduction. I am very new at this as I have only had my K3 for a few hours online and there are a lot of settings for the noise reduction and noise blanker. I, at least, am confused as to a starting point and what might work best on what types of noise.
Is there a tutorial or explanation online/available? 73, Jim ----- Original Message ----- From: "Dave Martin" <[EMAIL PROTECTED]> To: "elecraft" <[email protected]> Sent: Saturday, August 23, 2008 7:54 AM Subject: Re: [Elecraft] K3 noise reduction vs. Clear Speech speaker > > Somebody recently was asking if anyone has compared K3 NR with external NR > > systems.
