Versatile Auto-ranging Power/SWR Meter
The Elecraft W2 wattmeter provides fast
LED bar graphs to keep track of
transmitter and amplifier performance. With four power
ranges (2/20/200/2000 W), the W2 can satisfy the needs
of both QRO and QRP operators.
Sensors optimized for
144-450 MHz and HF-6 m are available
The sensors use standard CAT5
shielded or unshielded cables.
The W2s built-in RS232 port allows you to use a
computer to read both power and SWR with higher
accuracy, as well as to set and check alarms, turn the
LEDs off, and other operations. You can use the
supplied PC software, or write your own remote-control applications.
Factory-Assembled or No-Soldering Kit
Product is in production.

Great unit at a decent price.  Time owned: 0 to 3 months
I was looking for a new SWR/wattmeter (to replace my Autek Research WM-1...a good analog meter) that accurately covers 160 thru 6 meters with bargraph (LED, LCD, etc) readouts, a computer interface for accurate digital numbers, and more (SWR and power) adjustable options. The PowerMaster II, LP-100A, WN-2B, etc, are all great units, but all are priced over $475, and they have more diagnostic functions than I really want or need.

Enter the Elecraft W2. The kit version is priced at less trhan half of the other units, made by a quality company, and has just the features that I want...namely forward power (peak and average), SWR, and reflected power (thru the computer utility program). It also features an alarm and shut down of your amp keying circuit in the event of high SWR.

Save $60 and buy the kit version...super easy for ANYONE to assemble, with the hardest part consisting of scraping the paint off the inside corners of the cabinet parts for proper electrical contact. The unit functions exactly as advertised (read the specs and manual on, and the other reviews), and the computer interface program is easy to download and install, free from the website. The accuracy compares favorably with the Autek WM-1, which I was always satisfied with. I'm not a stickler for supreme accuracy down to the last watt, as plus or minus 5 to 10% is OK for me.

Two thumbs up....highly recommended.

Great Kit  Time owned: 0 to 3 months
Nice kit and useful shack accessory. Kit took about 1.5 hours to assemble. Assembly was very straight forward. Instructions are clear and easy to follow. The most difficult part of the assembly is removing the paint from the inside of the cover.

I like the free software interface downloaded from the Elecraft website. No issues using the XP operating system.

I found that when I left the case screws a little loose, as indicated in the instructions, very little force was required to line up the screw holes.

Nice product.

Great for remote monitoring and amp protection  Time owned: 0 to 3 months
The kit was easy to assemble (<30 minutes)and easy to install along with the RS-232 cable and software. The accuracy is a little lacking and the LED brightness control does not allow from the factory to be set to a comfortable level. I don't think these two issues downgrade it to a 4. I am using it in a remote shack and it does a great job protecting my amplifier and giving me relative power output. For the price and functionality, I think it is hard to beat!

Small but Bright  Time owned: 0 to 3 months
I bought the factory assembled unit. It's just a good solid SWR/POWER meter and not that expensive for what you get.

There may be a few watts play between led segments at the higher range, I don,t know that for sure but if you must have the most accurate meter out there that measures down to that one accurate watt.. good luck.

I like it  Time owned: 0 to 3 months
Works as advertised, in my situation the remote length is 50 feet away and the accuracy is a little off, but not terrible. The convienience is worth the price, software also easy to install and works fine

Not Happy  Time owned: 0 to 3 months
This was my first purchase from Elecraft. Sorry to say it wasn't very good. The W2 was D.O.A.
The worst part was trying to convince Elecraft is was bad from the factory. Also the person I talked with didn't even understand the product. He said he would send a replacement IC to plug in the socket. I asked what socket? All components are board mounted and coated , sealed. No sockets. A new board was finally shipped. So after 5 weeks I had a working W2. I didn't like the way it preformed so I sold it and purchased my old standby Autek Research WM-1.
I guess I expected a lot more from Elecraft after reading the comments for years about the other gear they produce.
The W2 is priced way to high for what you get.

Updated software makes for a keeper  Time owned: 0 to 3 months
I withheld my review knowing that once I purchased the kit there would be firm/software updates and would reserve judgment until the product was "mature". Elecraft staff are very pleasant and responsive to customer concerns and early release issues have been quickly corrected.

I built the 2KW unit. The device allows updating and has computer software to closely monitor detailed forward and reflected power levels while the LEDs give a quick view of transmission characteristics. Alignment via utility has also improved. When I first received my unit there was an issue with instability when changing from the factory presets. This has been corrected by updates.

What I really like about the unit, besides the PC software, is the ability to interrupt the amplifier with the device in the event of high SWR. I can leave the transceiver on and adjust settings until the SWR is brought down. A great tool to protect against the loss of my amp. My Solid State amplifiers have built in fault circuitry but I would rather have the fault detected quickly by the W2 before the Amp. It does this for me when I inadvertently forget to change antenna or my frequency is in the wrong part of the band and the SWR is high.

The build for this unit was quick and easy. I have built plenty of equipment in the past so no big deal. The instructions are clear enough and the builders Elecraft reflector is a place to ask and answer questions... or pick up the phone and get help.

Criticism of accuracy in most cases is of little value based on non-lab comparisons. I find the meter to be right on. This device is a keeper!

Form follows Function  Time owned: 0 to 3 months
I recently purchased a W2 in kit form. From opening the box to putting the W2 in-line took about 45 minutes. The kit goes together very easily.....there were no assembly issues. I added the power-on mod, which involves soldering 1 short jumper. If you do not put that mod in, there is no soldering required.

The unit is compact and well designed. It has a nice clean look to it. The led bar graphs allow for a very quick glance to see what is going on. I find this useful when operating. It is very easy to glance at the display to get an indication of output power and swr.

The firmware utility is simple to use, as is the interface for the computer if you wish to have an on-screen display.

I'm pleased with the does what it was designed to do very well......

Very nice SWR/wattmeter  Time owned: 0 to 3 months
The W2 does exactly what it is supposed to do. And it does it pretty well. Assembly went smoothly. The problem IMHO is that it was developed by people who know a thing or two about power measurement, accuracy, resolution, precision and the like. For people who may not always be familiar with such matters... or are just accustomed to needle meters.
With the W2 Utility and/or the W2 PC program, it is quite easy (and for some people maybe comforting) to adjust the W2 to match the 5+% error of your BIRD which is by no means supposed to be a standard (even if recently calibrated), hi...

Another great Elecraft product  Time owned: months
I bought the kit and it went together easily and quickly. I don't have a Bird meter but the W2 agrees for the most part with 3 other meters I have and I doubt all 3 are wrong. I like the LED readout and the first couple of versions of the computer display software are excellent. I had 2 glitches. 1. The supplied sensor to meter cable developed an intermittent and 2. I had some trouble with the software. Why do I rate it a 5 even after a couple of problems? In both cases Elecraft responded very quickly to my questions - one of them on a Sunday - and both problems were resolved very quickly. I doubt very much that any other ham manufacturer would have done so. Great company and great products.
