If it was me I'd use the second radio to relieve some of the congestion you have on your feed now.
Split off the two departure frequencies (119.050 and 121.200) onto the new radio and keep what's left on the one you have now.
Okay, thanks for your suggestion. Yes, I will dedicate one feed to either app/dep frequencies or ground/tower frequencies.
The original feed will still carry the Amsterdam radar center frequencies, as I prefer listening to those myself
Right now I m still struggling getting the Raspberry PI connected to the Intenet, but I hope the second feed
will be going up soon ..... for the moment I am feeding Schiphol app/dep during the daytime hours (0800-2200z),
and switch to center frequencies plus app/dep/tower during the nighttime hours.
