The new G versions of the popular TS-570D and TS-570S add significant new features to these already nicelyequipped mid-priced transceivers.

What’s New?
I happened to have access to an early production unmodified TS-570S. This gave me the unique opportunity to set up the new G version side by side with a first generation unit. The G version includes a handful of new abilities and improvements on some of the original features. One of the more notable changes is an enhancement of the NR1 DSP noise reduction feature, used primarily on SSB. In the earlier model, the SSB noise reduction works well, but imparts the typical watery audio quality common in most of the current DSP implementations. In the new G version, a menu item has been added that allows you to vary the amount of noise reduction employed. While on the earlier radio I often found myself leaving NR1 off except under extreme conditions, with this new flexibility I can strike a balance between the amount of noise reduction and the resulting reduction in the overall audio clarity. There’s also an “auto” setting that varies the level of noise reduction based on the signal strength.
