Fabulous Transceiver Even Today  Time owned: more than 12 months
When I was a young man in the late 80's I coveted the Kenwood TS-940. Unforunately I couldn't afford one. $5000 was a lot of money in those days. In my opinion in it's day it had no rival. I picked one up at a swap meet a few years ago and it still receives unsolicited compliments on the TX audio. The RX audio is fabulous. There is no question that throughout this era Kenwood knew what they were doing when it came to TX and RX audio. The problem now is that it is an aging radio and very complex internally. In my opinion these stately HF Transceivers are worthy of any effort to maintain. I will use mine for chewing the rag as long as I can operate.

Love it.... II  Time owned: more than 12 months
In addition to below....

The RF Stage modulation is

Asymmetrical 95% Neg / 200% Pos


Well, I just got my TS-940SAT back from tech and employed KE1IZ AM Mod, and N8RWS SSB and Reciever Mod, and the mods work great.

Opened up TX audio bandpass to 50hz - 7500hz.
4000hz 455 and 8.830 IF filters for SSB.
15000hz 455 IF filter for AM.
RF Stage modulation for AM.
Opened RX audio bandpass to 50 - 10000hz for AM
Opened RX audio bandpass to 50 - 4000hz for SSB

Using a Heil PR40 mic and Behringer rack, SSB and AM working very well.

I could get a TS-950SDX but I always liked TS-940SAT since I first saw the radio back in 1989.

Great Radio!  Time owned: 0 to 3 months
Acquired a non-worker for nothing, found dry joint on AVR board, changed the pass transistors for 2N5886s and did the Fan mod. Replaced button cells and re-calibrated. Wow, what a great radio, great audio quality and good on adjacent channel and strong signal performance, getting around 0.12uV for 10db s/n ratio and achieves 110 watts o/p no problem. Mine is a late serial number one and had a lot of the later Kenwood mods incorporated.
This ones a keeper!

Still in demand!  Time owned: more than 12 months
Kenwood made a lot of TS-940's. Although they had a few issue's on the earliest run's, all were fixable and as the serial numbers grew the issue's went away. By no means would I purchase one based on the serial number though. But would purchase it on how well it worked now. If it's an early serial number and all feature's are working as intended I would have to believe that all fixes were done years ago. My current 940(I've had a few) is a 50 thousand range number which is one of the earliest. It works as well as 8-9 mill numbers I've had, maybe better. 130 watts out, really don't need to use the processor and puts out a clean signal. Although it's a pre-DSP rig it still has a great receiver. If your looking for a great classic and are willing to spend 6-$800.00 you won't go wrong purchasing a working TS-940. Well worth the investment. 73's

Trio TS940SAT  Time owned: 3 to 6 months
A superb looking base radio for starters. Typical Trio/Kenwood audio reports (superb). Slope feature is very handy for shifting the QRM. The auto ATU is a bit limited and slow (but then again so am i ha ha).Can be renound for bad solder joints in later life which is about now!
Weighs a complete tonne!!!!!!
I love mine....

A classic that holds its own today!  Time owned: more than 12 months
Very similar to W3PYF down below, I inherited my TS-940sAT, and my call sign, from my Dad.
After he passed, the 940 sat on a shelf in my home for 20 years. I'd turn it on and hook it up to a long wire for an antenna from time to time, but that's about it.
In November 2011 I got back into the hobby big time. I've logged over 3,000 new contacts on the old 940 in the past year. Yes, I had intermittent problems to solve in the first 8 months of operation, almost all due to oxidized connectors on the many cable harness to PC board connections. However, a meticulous cleaning has now made it completely reliable again. I just love this old transceiver!
I've added a PieXX serial interface and control the 940 flawlessly with Ham Radio Deluxe. I've also replaced the CR2032 memory batteries, and fixed a burned out meter lamp. I've replaced some of the caps on the AVR board too, but they weren't yet bad.
I get numerous, unsolicited compliments on the audio quality. I did buy a new MC-60A microphone, and I'm told I have an "on-air" broadcaster's voice too. I'm sure all this adds up to the great audio quality comments.
So, Dad, if you're listening on 40m up there, I hope you're smiling!

Perfect for me  Time owned: 6 to 12 months
I have to admit that when I got this rig it was with the intention of selling it to fund more purchases for my 80's vintage Kenwood collection but then I actually used itů Wow!

It gets used every day for several hours on SSB and CW and I've never had even 1 issue. Even just running a small inverted V dipole I get great signal reports from the nets I check into as well as my rag chewing buddies.

I was really lucky to have found one loaded with options and maybe my experience with it would be different if it were a stripped down rig, I don't know. But I do know I love using this rig with it's lack of menus and solid performance.

If you find a nice one I'd say get it!

Better than I could have guessed  Time owned: more than 12 months
I inherited my 940 from the "original" W3PYF, my dad Clarence, in 2005. Even before I got it on the air, I filed for and received dad's call - so it has never been used except as "W3PYF." Dad was largely on 3999 until he went into an independent living facility about 2 years before he died. So it sat for 3 years before I inherited it and got in on the air into a Cushcraft R5 vertical.

A few weeks after I fired it up, the digital display began flashing, and the VFO clearly wasn't locking. A call to Hal Guretzky at Land Air Mobile in Brooklyn quickly diagnosed the problem. Hal noted there were several issues in the 940S he knew well - so I drove it from CT to Brooklyn. Hal fixed them all, and 6 years later, it has been solid.

I now live in a small suburban lot, where - living alone - I ran it into a Butternut vertical with several above-ground tuned radials. I quickly discovered that a vertical and barefoot 940S is no way to work much SSB - which is just fine for me, since I work only CW, and have little time fot ham radio, as I am self employed.

A few weeks ago, I finally put up a K1JEK Cobra Ultralight, about 15 feet up at the apex, and with feedline wrapped around the yard. WOW - suddenly, SSB came alive! Great reports on 75, 40 SSB. Now, I could really appreciate what a great rig it is.

The bandpass adjustments on both CW and SSB are really a pleasure. It enables you to slice through almost any QRM to pick out a weak DX signal. I bought the CW filter here on eHam classified, and it made a real difference in killing adjacent-frequency QRM. I had discovered a Radio Shack DSP unit in my late dad's shack, and one day about a year ago, put in on the 940S for CW. WOW again - really made signals pop out of the background.

I'm sure I don't use a fraction of the capability of this oldie. It's a real joy. It's a heavy box, but with a great deal of flexibility. Not the most current design, for sure - but for basic CW and occasional SSB, you could not want a better rug

Great radio  Time owned: more than 12 months
I'm the original owner of a TS940SAT, which I've had since 1985. I echo the sentiments of others who really like this radio. My previous radio was a Heathkit SB102, so naturally there is a night and day difference in performance. I don't miss the days of 6146's and the lack of a noise blanker for reducing power line noise. The TS940 has just about everything I need and more (with the sole exception of a really fast autotuner). The receiver sensitivity and audio quality are amazing, as well as the transmitter performance and capability. I have very few complaints.

I have performed all TS940 maintenance myself, including 3 unexpected repairs. One was the result of an improper connector assembly on a PCB, one was due to a bad connector solder joint, and one was due to an internal coax cable bending too tightly, resulting in an intermittent short. Since I've owned this radio for 27 years, that's an average of one problem every 9 years. That's not bad! I wish I could say the same for other radios that I've owned.

Since my SN is relatively low, I have performed most of the Kenwood service bulletins. I especially liked the 'talk power improvement' which produced a very noticeable change in SSB peak power. I also updated Q101 and Q102 on the AVR to avoid future issues with the +28V supply, and lowered the fan turn-on temperature as suggested by others.

Overall, I am very satisfied with this radio. I have no regrets about purchasing it in 1985. I feel no compelling need to upgrade to the latest DSP enhanced technology. I also own a Timewave DSP599ZX digital noise filter for the audio, which I rarely use. There might be some other reasons to upgrade, but for now, the TS940S does what I need very well.

Follow up to earlier review  Time owned: 3 to 6 months
Since picking up the radio back in late spring, had a couple of battery issues but after new batteries the radio is working great. I have installed the Piexx board and the computer control is a big plus. Makes logging the QSO's so much easier. I installed two PC fans on the back, one for the final amp, one for the power supply and the radio runs quite cool. Using a Behringer XM8500 Ultravoice mic ($24.99) and get great audio reports. I do miss a dual VFO display but it's a minor inconvenience. All in all a great radio.
