The Kenwood TS-870S transceiver does things that no other rigs can do in stock form. Even though this
HF radio is no longer made, many Amateurs choose this model as their number one HF
transceiver to this day! Not only does it have one of the cleanest and well made receivers
and advanced IF DSP and digital noise filters, it also has the ability to transmit and receive higher
fidelity audio than nearly any other non-modified transceiver on SSB, due to its wider filter
capabilities. In its wide filter settings, it is one of the preferred rigs for enhanced SSB audio
due to its wide and flat audio response on SSB (you can adjust to this width easily within
the menu, without needing to modify the radio). For wider receive bandwidth, simply use its
adjustable digital filters which are fully adjustable from 1.4 and 6.0 kHz for the high pass cutoff, and 0 and
1000 Hz for the low pass cutoff.
The Kenwood TS-870S had and still does have
one of the most advanced DSP technologies available. It actually uses "two" DSP processors (in the
IF stage) that has an incredible dynamic range of over 140db! It also has digital IF filters
that are sharp enough to create more than 100db of pass band attenuation, so you can say goodbye to nearby
interference and unwanted signals! Its DSP noise reduction actually has two methods of taking the noise
away from the signal, which are LEM (Line Enhancer Method) and SPAC (Speech Processing Auto Correlation).
Again, this is true IF, not the less effective AF DSP. Many hams will argue that the TS-870S is the most
advanced amateur radio ever made by Kenwood, which explains why it's still the number one preferred
choice by many amateur operators.
