[Elecraft] Wider bandwidth while listening to AM SW on the KX3?

Yes, I’m sure this is true, George.  I do hope that my little bug in the ear reaches the right people, and if time and resources permit wider DSP filter bandwidths become possible.  I suspect many people who own a KX3 have a little list of features they would like to see added, but I don’t want to try to sounds like I’m complaining.  The KX3 is the best radio I ever owned and I love it just how it is, but I would like it even more if my wish came true!

Thanks to all the others for their input as well.  It was interesting to hear from Al and his experience in college, and many thanks to Martin for his suggestion as well.  So far I have only used my iPad and iSDR to provide panadapter functionality for the KX3, preferring to take the audio straight out of the KX3 instead of iSDR because I do really like the filters and noise reduction.

Thanks also to Don, I do realize that the KX3 is primarily a ham band radio and I do notice sensitivity suffers a bit outside the ham bands, but it is still excellent by any standard even when compared to top-dollar commercial and military communications receivers, let alone consumer grade shortwave radios.

Contrary to real life (heh) when it comes to the radio I tend to listen more than talk or send, and I listen to the shortwave segments more than the ham bands, still being a bit of a shortwave buff at heart.

Thanks again and happy radioing!
