I will roll with the current setup for awhile but i have seen on several occasions how I can deploy the use of the 2.1 kHz filter in noisier band conditions say on 40m to improve intelligibility and readability of weaker signals.
If the 1.8 kHz filter will continue in that line of improvement, it would probably be warranted down the road to add the 1.8 khz filter and reconfigure my current setup on this K3. I do have to hold off for more spending on the radio since I focusing my green stamps on a SteppIR 3 element antenna upgrade project and my wife wants an incredibly expensive baby room for our first.
