Decent but flawed  Time owned: more than 12 months
Mine is almost 2 years old now. Very nice design concept with a flawed delivery. I also own the PX3 display unit and the 100 watt amp. I am going to add the internal tuner soon.
Not too long out of warranty the radio stopped responding to frequencies programmed into memory so I had to send it back for repair. I will advise the outcome of that expense.

Design flaws:
1. The VFO tuning knob is too thick, always manages to block your view of the lower right corner of the display.
2. Installing the eight AA batteries inside for portable operation is awkward and puts your radio in a situation where you could very easily do significant damage to the radio.
3. It overheats easily.
4. The auto tuning feature for the CW decode is wonky, overshoots and de-tunes itself.
5. Using the amplfier and panadapter creates a huge mess of wires all around those units.
6. Reception in the lower portion of the AM broadcast band is rather poor, the receiver becomes deaf down that low.
7. Operating position is odd, you really need to make some sort of stand for the radio, it lacks a natural using position. Laying on its back the VFO knob blocks your view of the display, sitting leaning back means you cannot use the attached morse key, standing upright to fully see the display means the speaker is covered.

The design concept is very good but using the radio has some oddities. Despite mine being sent back for repairs just out of warranty I still give it a 4 of 5 for overall CW and SSB performance and in use as a general coverage SW receiver.

I figured out how to wire an external key!!!  Time owned: more than 12 months
I'm not sure, after reading the manual and talking to the people via E-mail that they are from around here. My wife has said I can confuse simple conversations into stuff no one can understand......... That said. I am happy with the rig. Worth the price. I own a motorcycle and this rig is a take anywhere talk to the world rig. but......I've been trying to connect up an external straight key. I have been Emailing with the company rep and I don't think they are from around here (if you know what I mean). If you want to wire a straight key to this rig. Use the convenient key 1/8 plug or receptacle on the left side that's what its for. Wire one side of the key to the tip of a stereo plug wire the other side of the key to the middle ring of the stereo plug. Do not touch the ground. Key1 should be set to hand. Other than that the KX3 is a great transceiver. I use the paddles and they work great no one misunderstands me because of my "fist". I live in Arizona (no trees)and use a slope-er di-pole the ends are a foot off the ground the middle is maybe 12 feet off the ground. I actually get out and talk to the world with the KX3 so I would give the rig a 5 but I do not have an easy time reading and interpreting the manual. it's just a bit off. I'm an older person so maybe the problem is just me.

superb  Time owned: 0 to 3 months
I've had my KX3 for a couple of months now. I have an FTDX 1200 at my home QTH, you may see it on the ad pages soon. I've owned a K3, two K2, two K1s and now the KX3. Great little rig. I built the HR50 amp go go with it but I'm thinking of going ahead and getting the KXPA100 and Pan Adapter especially, if I sell the FTDX 1200.
This is a great rig for QRP and I've had a bunch of QRP rigs over the years. Great size and full featured. I worked a bunch of CW contacts from my camper in CO over the last couple of months running 1 or 2 watts to a 32 foot vertical. THe built in ATU does a great job too.I also regularly checked in to a 40 meter traffic SSB net in Texas running 12 watts with the same antenna.
I really like the built in paddles and have no issues at all with them. Great rig, superb service from Elecraft. Buy American!

Breath of Fresh Air  Time owned: 3 to 6 months
This is a nice radio indeed.. as I use it, I find myself not using the ft857 sitting next to it..
The receiver is good, and reports on the transmission are good as well..
I couple it with a 100 watt linear to boost the power..
It is a new style of radio with a different design.. once I had a problem with a jam in data mode which was resolved with tech support from elecraft sending me a firmware upload..

Some of the keys seem a bit less than ergonomic and confusing to use, and a little bit of consumer research and rationalization might be an idea..

Still all in all, really good to see something new and different which is a pleasure to use as well.. keep it up elecraft and all the best

Superb  Time owned: 6 to 12 months
Top notch. Soon to be released (now available to test) firmware update will allow 10W output down to 10V on the batteries! More swagger for the little gem! All the superlatives have been used up. They all apply.

Nice Portable CW rig  Time owned: 0 to 3 months
I've had the KX3 almost a month. It is a step above all the previous radios I owned and the first QRP radio I've owned especially with regard to operating CW. Having non-menu driven front-face controls for changing CW settings and a pin-diode full QSK are big changes for me compared to my previous rigs.

The display is enormous given the size of the rig and shows me everything I want to know. The tactile feedback on controls is generally ok but a bit mushy sometimes.

I've used it portable a few times but mostly from the shack. When portable its ATU is simply amazing at matching my random long wire. Others have reported that the internal batteries don't last long but for me they've been good enough to operate fully from internally batteries for 2-3hrs at a time but I spend more time listening than sending.

Almost all my time with the radio has been CW. I've tried a few phone contacts but haven't had much success at QRP SSB. I've tried PSK from the paddles on one QSO. It was kinda neat. The memories work well for contesting and are easy to use without going into any menus.

Deficiencies are few considering it's size but things I'd like to see are:

- Two separate knobs for RF and AF gain controls. I find that I'm frequently pushing the single button to switch between RF/AF gain due to working weak copy QRP stations.
- The built-in speaker is pretty useless. It buzzes and is not clear and there's no amp to drive an external speaker. My Yaesu HT's have the same size (or smaller) speakers and they sound great so I know a small speaker can be good with the right design. I have to use earbuds/headphones for other than casual listening.
- I can hear a lot of digital artifacts at higher volumes through good earbuds. I assume it's just the aspect of a SDR architecture but I hope a future firmware update will clean that up. It's annoying to me. If I turn down the audio or use cheaper headphones I can't hear it but I can't hear weak signals as well either.
- I switch frequently between paddles and straight key. That requires entering the menu to change. Cheap radios such as the YouKits recognize the difference when you plug in a straight key or paddle so I'd like to see a firmware update to support this as well. I plan to wire up a phono plug for the proprietary front paddle connector to get around this but I'd prefer the radio to support from the Key1 jack.

The portability is what makes most deficiencies acceptable. It's just an amazingly portable HF rig. With internal batteries and the ATU options I'm not aware of anything that compares to it for just pulling out of the bag, plugging in a wire and operating.

Good job Elecraft. Keep up the good work

Amazing little package  Time owned: 3 to 6 months
The KX3 is a very well thought out radio. The kit is easy to assemble, took me around 6 hours going slowly and carefully. The quality of the components is top grade and the finished product is solid and has a really great feel to operate with all controls feeling positive in action. The internal ATU will match just about anything, really useful for portable operating. The receive performance is good as can be seen from any of the professional reviews, but a feature that you do not see mentioned often is the binaural audio. I use the "delay" setting and it makes a huge difference to readability of weak signals. I listen to the SW broadcast bands alot and the binaural audio makes these stations so much better to listen to. I have not enjoyed using a receiver as much as this since the days of my old HRO, and this is in large part due to the binaural audio.
I have the built in paddles, battery charger and the filter option. All of these work well. I bought the KX3 as a rig for use outside but I use it frequently in the shack as I find it so good to listen to, and so easy to operate.
It is expensive, but you are getting a top grade, up to date piece of equipment which will not need replacing for many years.

Elecraft has done better  Time owned: 0 to 3 months
I have very mixed feeling about this radio. Elecraft as a company, and their service, is without peer. A couple of K3's and a K2 were near perfect radios. No complaints but Elecraft missed their high mark with the KX3.
This radio is to replace my IC-703's and the small size was a large part of the decision as well as the internal batteries. The unintended consequences came as a surprise as in the past Elecraft hasn't let me down.

Application conditions in this case are casual operation. Picnic table portable.

Great receiver
Small package
Lots of features

Mechanical construction
Internal batteries
Heat dissipation
I/O connectors

The physical package is contrived. Previous Elecraft's have had unusual/innovative physical construction but this time there is much room for improvement.
Battery access is kludgy. The thumb screw loosening process to release the support feet, which are too short, is anything but elegant. Once loosened proceeding to open the case to change batteries presents the ribbon cable which is too fragile as are its connectors. The battery case and threat of shorting batteries against the hold down screws just plain yucky. The battery holders themselves are so poorly wired and physically configured makes me wonder if someone else designed it. Never expected something this weak from Aptos. The optional paddles are awkward and there is no provision for covering the opening if you choose not to use them. These issues fall short of expectations from the wizards at Elecraft.
The heat buidup problem is a design flaw resulting from the poor physical configuration. The idea of spending an additional $100 for a useful heatsink just isn't up to Elecraft's standards.
The speaker is sad. You really need something else like headphones or a powered speaker.
Relying on weak board mounted connectors is a low brow point of failure.

The rig is too heavy for it size and shape to be easily handled without risking dropping it. With such densely mounted controls and the ends covered with cables it is difficult to move around or hold in your hand. Kind of defeats the purpose of keeping it small. Again purchasing after market replacement end panels for protection of the knobs and to gain handles was unexpected and weak design. Such additions seemed unnecessary until the radio was in hand.
The rich feature set and great receiver are betrayed by poor physical design choices. Elecraft can do better. It is asking a lot and most operators will adapt to the flaws but they are flaws none the less and disappointing from a company which has managed such wow factor in the past.

The overall impression creates a suspicion the product was rushed to market.

Elecraft service and support are beyond reproach and coupled with the rig's performance make it easy to overlook the many problems. No other company equals or exceeds the high standard Elecraft sets with its customers.

This radio was a kit. I emailed support when I discovered the contacts in the battery plug were malformed and pushed out of the housing when trying to connect. I managed to reshape them and make them work but by then support has shipped an unsolicited replacement battery holder assembly. There is reason to pay more for things when it results in almost instant response and solid support after the purchase. Elecraft is like no other manufacturer of amateur radios.

Nice TRX, poor mechanics, unsolved hardware bugs  Time owned: 6 to 12 months
My first contact to Elecraft was an K2 with nearby all options. I was very happy with this TRX so I deside to switch to an KX3 because of less weight and smaler package. The KX3 is realy nice and the receiver is outstanding. But on the other hand there are (too) many negative points.

- small package
- many many features (PSK31 read, voice memo, ...)
- perfect receiver performance
- tuner can handle EVERYTHING

- machanic design is very poor.
- Loudspeaker is very poor and craky.
- VFO tuning noise on 10m and 6m.
- battery charger only work between 0C and 40C temperature inside the case. There are many situations charging the battery is not possible.

At all I would say the KX3 is a very very good transceiver but it is too expensive. The mechanic design should be much better!

I will keep mine but I would never buy it again.

Ham radio is fun again  Time owned: 0 to 3 months
I've owned my KX3/KXPA100/ATU/PX3 for a couple of months and Elecraft has done it again...produced an outstanding product at a price point that doesn't break your pocket book. Ham radio is fun once again and a real pleasure working QRP. As I got older and started downsizing my station, Elecraft was a perfect fit. Great specs and small enough to fit just about anywhere in the house or in your backpack. I've owned the "heavy iron" rigs and also some of the latest SDR's, but have yet to find anything that approaches the KX3 when you compare features/price with the other manufactures. Product support is extremely important and they have a couple of very active user forums that provide a venue for just about any question relating to the Elecraft product line. If you can't find what you are looking for there, it's easy to get in touch with someone in tech support.
