I'm hoping that for diversity I can just switch off my main rx filters and have both with only the stock 2.7kHz filter. I only need the narrow roofing filters when I am near extremely strong local stations, which doesn't happen much. I don't see a need to have 2 sets of roofing filters unless

I've finally put the second RX in my K3 #22. I have 2.7k filters with -0.86 and -0.87 offsets- have I ended up with filters that are matched enough for diversity reception? The thought is that it'd be useful to have two low-band antennas useable simultaneously when on DXpeditions. I still need

Lyle, I can understand why the beat effect can happen at certain frequencies. I read the message about the rounding errors. My question is: can you give an indication of how often this happens. Of course it depends on freq and filter offset but still, can you give an idication how bad it is.
