Hi Bill, In the K3 Utility -> Configuration tab -> Configure Crystal Filters, you will see that each filter has a Gain setting. You can change the gain on a per-filter basis to maintain approximately the same overall gain. Generally the smaller bandwidth filters require a few more dB gain than wider ones.
An example: 13 KHz: 0 dB 6 KHz: 0 dB 2.8 KHz: 1 dB 1.8 KHz: 2 dB 0.25 KHz: 4 dB These settings work well in my K3. Yours may be somewhat different though. Don't forget to balance filter gains for the subreceiver if you have one. 73, matt W6NIA On Sun, 2 Mar 2014 11:37:58 -0800, you wrote: >I have the 2.1 KHz (for SSB) and the 250Hz (for CW and digital) >filters.
