There will be a slight pop when changing bandwidth between 150 and 100 Hz as the K3/K3S disables the RXEQ at bandwidths less than 150 Hz. The level of the "pop" will be related to the amount of EQ in use *around* *the center of the passband* (e.g., "pitch"). If for example, pitch is 500 Hz and bands 4 (400 Hz) and 5 (800 Hz) are 0, there will be little or no "pop". However, if one has 400/800 Hz set for significant boost there will be a fairly loud "pop" as the level changes. 73, ...
