Great radio!  Time owned: more than 12 months
I have had my TS-940SAT since 2006, and it was great until last year. I started to notice AC hum on RX and, then, on TX, so, I knew that the elderly power supply electrolytics were on their way to capacitor heaven. I stopped transmitting, but I still used the receiver.

A close lightning strike last autumn sealed its fate; in addition to hum, the receiver was nearly completely deaf. Last week, I finally got the urge to fix her, and, sure enough, a re-cap of the power supply and some repairs to the front end of the receiver brought the old girl back to life. The input attenuator relays are still welded in the "0dB" position, but, as long as I stay away from Field Day, that won't be a problem.

It's amazing what a difference the repair of the power supply made; the famous Kenwood audio, which I thought was good before, is even better than when I got the rig as a twenty-year-old companion.

As has been said, you can keep your nested menus and DSP whiz-bang devices; give me knobs, and lots of 'em! I'll be hamming while you are reading your "War and Peace" owner's manual.

Kenwood knocked this one out of the park, but I'm saving my paper route money for a 950SDX. Nevertheless, the 940 is staying with me forever.

Happy TS-940 owner  Time owned: 0 to 3 months
I just recently purchased a TS-940SAT. From the day that I started using it I was given a multitude of great audio reports. The receiver section of the 940 is totally outstanding. The filtering is second to none. With the 940 and the MFJ tunable filter, I am able to get rid of 90% of the plasma TV noise from my sonís plasma TV. I waited too long to get one of these beauties and it will be a long time in use. Mine has a 9,000,000 plus serial number. I couldnít be happier and would highly recommend this transceiver to anyone.

Great, Timeless Rig  Time owned: more than 12 months
I've had my Kenwood 940SAT for over two years now, picked it up from an estate sale of a silent key, paid $700 for the rig and an MC-60 Mic. Added the SP-940 and SM-230 later, along with an external DSP.

I've had to do one repair since buying it two years ago, replacing a failed cap on the RF board which caused the receive to face until the radio warmed up when powered on. Other than that, zero issues with the radio.

Others say it has excellent QRN elimination capabilities on its own, I disagree. An external DSP is necessary to filter out unwanted noise/interference from adjacent frequency transmissions. During contest weekends, I can barely listen to the receive without the external DSP. Given the time period it was built, DSP wasn't available, but adding an external unit really completes this rig.

One thing I can say is that I regularly receive compliments on the legendary Kenwood audio this radio puts out. Almost without fail a new contact will compliment the rig's audio.

Mine's been a workhorse as my primary rig with hundreds of hours logged on it since I purchased it. Worth every penny IMO and doubt I'll ever part with it.

One thing I did do was find a "parts rig" for spare parts. My second 940SAT has bad DC-DC power supplies in it, but all other parts tested out fine. I suspect I'll have this radio a very long time, or until I run out of parts (which ever comes first.)

GREAT!  Time owned: more than 12 months
What more can be said about this superb vintage radio. I have owned mostly Kenwood radios and I inherited this radio from a departed Cb'er relative. I was told it suffered from "severe misalginment" but what I found was the "dreaded dots of death". I removed ALL of the waxy potting compound and resoldered the board from end to end and this 940 really is asweome. I use it more than my TS-B200. The 940 has a great feel and a great sound. There are a few drawbacks like :some needed controls on the bottom of a 50 pound radio and the s-meter tends to be a bit generous. Filters? I bought a used Datong and all my filtering issues are resolved and cheaper than installing narrow CW filters.
but all-in-all this is a keeper! I will use it as long as I can keep it alive. If anyone is looking for a really nice, on-the-cheap rig, this is the one!

once great  Time owned: 6 to 12 months
How do I rate this rig? When working, it's an awesome desk rig with great audio and very useful qrm suppression. You can pick them up for around $700US. They have an IF output that allows them to drive pan adapters. A separate listening antenna port. I could go on.

Now for the bad news. This rig dates from the mid '80s to early 90's (basically an early '80's design). During that time, Kenwood used a potting compound in their VCO's that eventually contaminated the board and components, causing the dreaded "dots" or VCO unlock. The TS-440 also suffered from this. In addition, the main VCO board is "padded" with a black foam pad that from heat and age will also cause one the VCO's to unlock as it surrounds an etch side mounted cap. Additionally, it seems that many also suffered from cold/crystallized solder joints. There are other issues (maybe a dozen factory FCO's), but these will universally affect all of these radios sooner of later. You get very little warning, other than a few minutes of intermittent or "warbly" audio. Some people have successfully melted the goo out and been able to re-pot with hot glue, others not so. No new spare boards available. If you can't do the repairs yourself, shipping to an independent tech is very expensive due to the weight (near 50lbs) and kenwood won't touch them anymore.

If you've got a well equipped work bench and parts source, go for it. If not, parts are getting scarce, and qualified techs are few and far between.

Can't do better  Time owned: 6 to 12 months
I bought this TS-940SAT about a year ago. It was in perfect condition. I have owned a lot of rigs for the last 48 years, but this is the best I have ever had or seen. You can have your menus and sophistry, I will take the knobs. I can tune and adjust this baby before you can grab your user manual. (I don't need one.)

The passband band tuning is fantastic. You can independently tune upper and lower bandwidth. This, with the sharp notch filter, allow you to pull even the weakest signal out of pile-ups. The audio, receive and transmit are perfect. I usually get whatever I am trying to get, even competing with the KWs and the beam antennas. The famous Kenwood audio has punch that gets the job done.

You can't do better than this. Looks great, too!

Great Radio  Time owned: 6 to 12 months
I love this radio.
I installed AM mod, and moved ALC loop to 225 watts.
On AM, it deadkeys about 20 watts and modulates forward to about 200 watts...pure loud Kenwood audio.
On SSB, I'm always getting compliments on audio quality.

Special thanks to Don, KE1IZ

My Baby!  Time owned: more than 12 months
I bought this rig in the early 90's from an owner who was not licensed????, it scared him with all the knobs! I have never had a problem with this radio, its worked over 110 countries and placed in top 10 last year in the 10-10 voice contest!
Love it, wish we could buy a new one :)

fantastic radio  Time owned: 6 to 12 months
I purchased my 940sat earlier this year,i already own a 930sat and sold all my other ham gear as the 930 beat the pants off everything i owned,that is until i put the 940 in the shack,wow what a fantastic radio to use,i only use cw but was tempted up to the ssb part of 80 by a local friend in salisbury who said its the best audio hes heard on hf for ages.
I agree with all cooments on this radio if you can find a good one get it you wont regret it..regards Dave..

works good after fixes  Time owned: more than 12 months
My rig is sn in 5mil range--found mods on internet--fixed factory mistakes easily. found broken wires on several plugs. removed pins with dental pick, resoldered leads , put back in. removed socket on A board, cleaned with eraser, sprayed leads and socket with tuner cleaner. Removing socket and soldering in proved too dificult on doublesided trhu board. Power switch seemed to be bad until I discovered it works if held in for a second. Since I bought it used, can't complain about broken leads. Someone probably pulled on them because of intermittent s
Clock still doesn't work. Big deal, I have 2 clocks and a computer in the room, one on the rig would be overkill. After all mods, etc, it works great and am very pleased with it.
