[Elecraft] Some bands and modes are always upconversion on the TS-590

[Wayne Burdick]

They're probably trying to save money by eliminating a bunch of tight  
band-pass filters for the ham bands. They're betting that no one needs  
high dynamic range on any bands other than 1.8/3.5/7/14/21 MHz, nor on  
any modes other than SSB/FSK/CW.

I beg to differ :)
