Wow, this has generated a very interesting discussion with lots of good
points. I do find it hard to believe that a 1.8 kHz roofing filter
won't be better than a 3 kHz one with a strong, clean, signal 2 kHz
away. But unfortunately, as we all know, there are many signals out
there that are far from clean. A quick glance at the external
panadaptor spectrum display I use (LP-PAN on the Yaesu IF output)
confirms this.
Going to find out shortly which rig works better for me, as a very
generous member of this list is sending me his O2 with a 1.8 filter so I
can do a direct comparison with my FT5K. I have full one button rig
switching set up so the rigs will be in identical situations. Same
antenna, speaker, etc, just one rig at a time.
Now I just have to figure out how to make a good video of the results.
While I'm at it, I'm certainly open to any suggestions for testing.
I think I can do this without a lot of bias except for the belief I
stated above regarding the roofing filters. But those results remain to
be seen. This Yaesu is the first non-US rig I have ever owned. Other
rigs have been two Flex radios,four TT rigs, plus Drake and Collins.
Stay tuned!
