Nice radio  Time owned: 0 to 3 months
I first saw one of these at a friend's house about 10 years ago and thought it was a great looking radio! I had been kind of looking for one recently after learning you can hook a second receiver to it and do dual receive with them. When one showed up used at Ham Radio Outlet for the steal of a price-$295, I bought it!

I didn't use it a whole lot as a different Ham Radio Outlet had a used Kenwood TS950SD at too good of a price to pass up so I bought the TS950 and traded the 870 for a mobile radio.

There is nothing that really stood out in my mind concerning the TS870, it was just an HF rig that seemed to do what it was supposed to do. The DSP noise reduction was ok. When you turn the NR on using the front panel DSP key, you then have to go into the menu to choose line enhanced NR (On setting) or the SPAC NF (Off setting). The SPAC is pretty good for CW, I never did like the line enhanced NR very much (what Kenwood calls NR 1) on later rigs.

The tuner worked ok on this radio, not as wide as matching range as the TS950, which will match anything. The keyer is a little unusual, you can chance the speed on the front panel, but any other settings require you to send a command string using the paddles, and then sending different letters to change settings. I would much rather do this thru menus. I can see needing to keep a cheat sheet handy for some time with the keyer.

The noise blanker was nothing to write home about. Kind of average, not as bad as some, but not as good as quite a few.

If you read the QST review it discusses how the narrow filtering is obtained: You have a 3khz filter at both the 2nd and 3rd IF, and they are overlapped to produce the set bandwidth. This should work fine on SSB but on CW you are going to have 3khz of CW signals existing at the 2nd IF. You might not hear them but the receiver is and it can affect the AGC and produce IMD products. I didn't get the chance to run the 870 in a CW contest so I don't know how this would play out in really crowded band conditions.

Overall, the TS870 has the really good Kenwood receive audio, is pretty easy to use, and has lots of nice features on it. You can set the SSB receive to a 6khz bandwidth if you really want to do HI-FI SSB. To me, the TS870 is kind of like the family sedan, not flashy but can get the job done.

OLD but not COLD!  Time owned: 6 to 12 months
Recently a lone TS-870s arrived in my shack-thinking it would be outgunned by the mighty IC-7700 next to it.. As time went by I found I was operating the TS-870s in Preference to The IC-7700.
I still can't quite place my finger on it--The TS-870s is really old, has no screen , old dsp etc. (NO BLING FACTOR!)

BUT-the TS-870s was pleasant to listen to-did not have the robotic audio of the Icom (with DSP off),the NB worked fine, was quiet,the "S" meter worked as it should,(don't get me started on the ICOM "s" meter and NB!-shocking!) and is mostly completely serviceable at you finger tips, ON the shelf by accessing the service menu. WAY ahead of its' time!.
Remember this is GEN.1 PLL / DSP!..(17+ years old!)

It communicates faultlessly via 19600 Kbaud to my Expert amp-so now I have a 1Kw radio.
The RX is not as strong as the IC-7700 re. close stations, but fine for what I do.
Needless to say , the TS-870s knocked the IC-7700 off the perch and the ICOM no longer resides in my shack!.

EVEN today, this Kenwood is an HF audio and technology benchmark and now I have TWO.

Best Rig Ever Owned  Time owned: more than 12 months
I bought my TS-870 brand new from Burghardt Electronics back in 1999 and have used it faithfully since then. It has never failed to perform and I always enjoy the pleasing audio that this radio is known for. Whether listening to AM, shortwave, CW, or SSB signals, this radio delivers outstanding fidelity every time. I can hear signals other friends eho live nearby cannot. The radio antenna tuner works flawlessly, even though I use resonant antennas for all my transmit frequencies. I LOVE THIS RADIO! Don;t know why Kenwood discontinued this rig so abruptly, but I am glad I have one. I used a W2IHY 8 band EQ to enhance the already pleasant audio transmitted from this radio. It doesn't take much to make this rig sound good , Ask anyone who has a TS-870. ESSB seems that what this rig excels in and I am a fan of quality audio. I don't use extensive racks of audio gear, just a W2IHY EQ. That's enoigh for me. Wouls I buy another TS-870? If Kenwood would make them again, absolutely! They don't make them like this anymore. Love my radio.

GREAT RADIO!  Time owned: more than 12 months
I owned a new TS870S way back when & always enjoyed using & got great results but like many other amateurs after a couple of years sold it & bought other radios, the grass is always greener on the other side of the fence syndrome! A few days ago I was lucky to find & buy an immaculate 870, and boy am I glad to have this radio again. The receive section really is excellent & out performs many of the crop of high end radios. The way all the operating parameters of the radio can be taylored through the menu system is a delight to use. First day on the air I received unsolicited reports on the quality of the audio with enquiries as to what was the radio & what microphone was I using. If you are considering buying one of these classics make sure, via serial number identification, that it is year 2000 or later as Kenwood improved the close in signal handling of the receive section. The radio is a keeper this time around. 73, Mike.

Rock solid  Time owned: more than 12 months
I purchased my TS-870S used off of eBay over 12 years ago, not knowing what I'd be getting into. Long story short, it's still the best purchase I've ever made in over 40 continuous years of amateur radio.

The 870 is not the quietest transceiver out there. It is pretty doggone sensitive, but I'm sure that it can't hold a candle to more modern rigs such as the latest Yaesu, Kenwood or Elecraft offerings. And it's not the MOST selective transceiver running - but it's good enough for me. I'm an avid CW fan and I've never, ever failed to complete a contact due to the shortcomings of the TS-870.

The built-in antenna tuner is simply one of the best and one of the quietest that I've ever used, bar none. I've tried a ton of antennas over the years and never failed to get a decent match, allowing full output power to however non-resonant and inefficient the antenna seemed to be. If I had to pick one feature out that stands head and shoulders above the others is this unit's usability and ergonomics. Want to change the keyer speed? It's on the front panel. Same with the bandwidth, notch filter, squelch, etc. NO control serves two functions; yes, there are controls that have an outer and inner knob, but these are easily managed. Not one single feature that you will continually change or adjust while operating requires you to go into a menu.

The DSP is first generation and while it does work somewhat, it's really not a game changer like it is on the new rigs. And if you're into somewhat fast QSK, the rig will actually do it fairly well, without noticeable chopping of the code elements like some of its contemporaries. As you can imagine, the relays can be fairly noisy doing this - it's a late 20th century design. Having said all of that, if you're looking for a great first rig - or an amazing backup - don't look any further than an 870. Mine remains my primary HF station (that will likely change soon), but this radio will never depart my shack.

Better than most!!  Time owned: more than 12 months
This is a great rig. I've had the newer Yeasu, and Kenwood radios, the FTX3000 and TS-590s. Bought them new and sold them pretty much new. The old 870 just sounds better on transmit and recieve to me!! It may not have a bunch of bells and whistles, but it has what is takes even in todays word of high tech rock and roll radios. And you can still work on it, IF you have too......

Great Radio  Time owned: more than 12 months
I bought my Kenwood TS-870 new in 2002, and I still have it. It works great for me. I never had any problems with it. I had many good audio reports with the TS-870. After 10 years, I decided to buy a newer transceiver to have a more modern rig. I found the new transceiver has few advantages over my TS-870. After owning the new transceiver for almost 2 years, I still have my TS-870 and I am not selling it, at least now. In retrospect, investing in a good antenna is much more important than going with the marketing brochures, and having the latest rig.

Old gold doesn't shine anymore  Time owned: more than 12 months
The main problem with this radio is the lack of filtering and its limited dynamic range. This Rig has lot of less then vital good features, nice cosmetic appeal and someone would appreciate its TX ESSB-ready capabilities, but it lacks in the field of the most important specifications. It is way old digital design and its 16 bit DSP cannot compete with modern 32 bit architectures. Compare this rig with a TS-590 for IF filtering and noise reduction or with an FT-950 for TX audio tailoring or with the most of the latest models for synthesizer phase noise and receiver dynamic range: You realize how this than innovative design has become surpassed.

Great Rig  Time owned: more than 12 months
I have had my 870s with internal tuner for about 5 years. Like everyone has stated, the receive audio is excellent. The tuning is smooth as glass. The weighted knob is very nice. I love the rig. I have about 30 HF rigs of all brands. My primary rig is my IC-7600. It is very good. But, in my estimation, the 870s is right up there. My 870s is my 2nd rig on the operating desk. It is a solid performer and the ease of use is wonderful. If you happen to run across one, try it and buy it if it checks out 100%.

Lovely RX Audio  Time owned: 3 to 6 months
This radio is just plain fun to use and a pleasure to operate. Mine was purchased used and is from a middle year production run. I use it for both rag-chewing and DXing. Truly beautiful RX audio tone and quality, just as many have said in previous reviews. Until I operated a TS-870S, I really didnít believe that all of these accolades about its audio quality could be true. Once I did, I found the praise to be well-deserved. While I have a FlexRadio that also has very excellent RX audio quality, there is something about the tone of this Kenwood that I prefer on phone. No matter how I tweak the Flex RX EQ, I cannot quite get it to match or better the pleasing tone of this Kenwood.

Faves: In addition to the RX audio, I like the weighted VFO knob, the simple displays and having dedicated knobs for all of the major functions. The ATU is very fast, the NB and Notch functions work very well. The Auto-AGC works well for me, I rarely need to over-ride it. Itís quiet, the fan hardly ever runs during full output. I like not needing to buy additional I.F. filters. Nice control layout with plenty of room between controls.

Less-Than-Faves: For my $0.02, the process for working split should have been made simpler. My experience is that the DSP NR is not the best for SSB or AM. I had built one of the KG4JJH DSP Speakers from the November, 2011 QST article and it works especially well with this Kenwood. This combo brings the NR up to todayís standards and I find myself using it a lot rather than the radioís NR button.

If you are in the market for a reliable, well-designed radio that is easy to operate and you love easy to listen to RX audio, this might be your radio. The listening experience is truly exceptional. Really!
