Digital Signal Processing technology is affordable to everyone with the Kenwood TS-570DG. This advanced design provides 16-bit DSP technology for superb audio, noise reduction, equalization and slope tuning. The result is dramatic interference reduction not available in analog designs. The new NR1 noise reduction system is adjustable in 9 steps increments or can be assigned to track input signal strength automatically. Both the NR1 and NR2 settings now track when changing mode groups. In SSB/AM/FM modes you can select a Hi/Low cut DSP slope tune using up to 441 possible combinations. In CW and FSK the DSP acts as VBT (Variable band Tuning) that alters the passband width for rejection of nearby signals.
This radio covers the amateur bands from 160 through 10 meters and of course features a superior general coverage receiver. Power output can be set from 5 to 100 watts. A preset auto antenna tuner and electronic keyer are built in. The menu system offers 46 types of functions for Technician thru Extra. Full and semi break-in, dedicated packet port and 57600 bps PC control. Keypad entry, 100 memories, IF shift, large LCD, Scanning and CW Auto Tune round out the many features of this transceiver. The MC-43S hand mic is included. (Please note that only one optional filter may be added).
The Kenwood TS-570SG is similar, but adds six meter coverage.
The earlier non-"G" models Kenwood TS-570D and Kenwood TS-570S are similar, but without the 3 added DSP CW filters.

Based on historic data, today's value of the Kenwood TS-570DG might be around:
I've been running the 570D for 2 years now and find it an excellent rig. I especially like the DSP filters in CW mode and can really tweak the weak ones out of the QRN. Not too fond of the Noise Reduction filters on phone due to ringing, but have heard the G upgrade eliminates this issue.I used it for 8 hours of operation in the 2009 CQWW Phone DX Contest and worked 60 countries in 8 hours and was able to easily filter QRM to an acceptable level even on strong stations operating 1 Khz apart!For a medium priced HF transceiver I think it is an excellent rig and highly recommend it. I use mine on Phone,CW,PSK31,MFSK,and Feld-Hell modes with lots of fun and enjoyment.One design flaw I've read about in the TS-570 Yahoo Group is that the Multi/CH optocoupler knob wears out pretty easy, but it is easily repaired (part costs $8.00).I haven't had that issue because I either operate the rig using the RCP570 Kenwood rig control software or Ham Radio Deluxe software.The RCP570 software allows control of all rig functions,memories,and menus, but I favor Ham Radio Deluxe because I can use my computer keyboard's spacebar for keying the rig. The RCP570 program also has a window for keyboard CW at the speed of your choice. If I ever do upgrade to a high dollar rig I will hang on to this rig as a back up.For the price I don't think it can be beat.I paid 600 dollars for mine along with a Heil Goldline mic on Ebay and have had a blast with it!
I bought this rig after deciding I wanted a change after being an Icom owner for many years. I was not disappointed. The features it has including the ATU, built-in keyer, two antenna capability and variable bandwidth filtering along with dual VFO's and well laid-out menu system had me sold. I have used the radio mostly on CW which is my preference and it has performed well above my expectations. It also performs well on SSB and I find it very stable and reliable. The extra features seem to be those most desired and Kenwood has filled that need very well. I will be very interested to see the new version due out in 2010. If you have an opportunity to buy one that has not been abused, you will certainly be happy with it's performance. This is definite a keeper and I hope to have many years of good service from it.
Been a good rig on the air. I have used it little on SSB, but it has been terrific on CW... i love the CW tune, but if you have a super strong signal on the band, it will sometimes interact. I can tune that out, but it has been a work horse for me... It reminds me of my first new transciver, the TS 520s..same reliability... not all the bells and whistles of the more expensive radios but suits my CW lifestye!
