Gents, I am searching without much luck for recommendations for the gain setting recommendations for roofing filters.
Specfically I have a 700 hz 8 pole and a 200 hz filter 5 pole. There is a gain setting in the k3 setup menue and I remember there were recomendations on how to choose this setting. However, I have not been able to find reference on the net. Please can anyone provide some guidance as the performance when these filters are engaged with digital modes is rather disapointing. What I mean by this is that a signal can be very clean with the 2.7 or 2.1 filter engaged but if I use on of these filters the signal becomes very poor. I want to use these to isolate close in signals but there appears to be a lot of distortation so they are basically of little use. I am betting that there is more to this gain setting than meets the eye and that is where my problem is. I have put the gain for these two filters at 1 and the 2.1 & 2.7 at zero. I will be playing around with the settings, but there is a method to set this parameter so I need to learn what and why so I can make them work the way they are supposed to work. Thanks and have a great holiday.
