[Elecraft] W2 Watt Meter firmware load?

[Glenn Maclean]

I recently put my K line station together K3S, KAT500, KPA500, P3. They are all 
working great! I have added a brand new  W2 watt meter. It came with version 
1.0 firmware which from what I understand has not changed in many years and is 
the latest version. I was testing my new W2 watt meter and it does not seem to 
go into firmware load mode. I hold both the on button and sensor button while 
powering the W2 on. I do not get the left blinking light as the manual states. 
What am I doing wrong? I would like the firmware load mode to work in the event 
I need to reload firmware. I am able to send commands to the W2 with my 
computer.
Any help would be appreciated. 
Thank you,
Glenn Maclean WA7SPY

Re: [Elecraft] W2 control wire length?

[Victor Rosenthal 4X6GP]

I don't know, but it would be easy to try with a coil of Ethernet cable 
and some resistors.
The question is, why do you want to do this? You can easily compute the 
real SWR and power at the feedpoint based on the reading in the station 
and the transmission line loss from the cable specs.

Hi,

I have a W2 with an HF coupler and I am entertaining the idea of putting it
out in a waterproof container just before the feed-point of my antenna
(non-resonant vertical). The run is about 75’. Does anyone know if there is
a limit on the cable length? If so, what is it?

Thanks and 73.

thanks Michael.
Its the setup screen in W2 that wont open.

[Elecraft] Elecraft W2 Watt Meter with Couplers

[Calvin]

For Sale are 2 Elecraft W2 watt meters with 2 directional couplers for 
each one.


Each watt meter has one coupler for HF – 6 meters 200 watts and one 
coupler for HF – 6 meters 2000 watts. They include all cables for the 
sensors, power cables and USB cables as supplied by Elecraft. Manuals 
are available on Elecraft web site. They are both in very good condition 
and work fine.


Price for one watt meter and 2 couplers and cables is $495.00 each.
All prices include shipping. I will take money order or a personal check 
and hold until it clears.

Re: [Elecraft] Elecraft W2: Calibration question

[Dan Brown]

There’s an adjustment that can be done in the W2 software, not the utility, but 
it just fine tunes what’s displayed by the computer, not the unit itself. 

The software, IMO, could use a bit of modernization. Really wish it could be 
open-sourced.

[Elecraft] W2 Sensors - calibration

[Michael Walker]

Hi All

At the moment, I am using a 200 watt HF W2 Sensor on VHF, and while I
realize it isn't far from perfect, it is perfectly good enough to tell me
if I have LOTS of watts out on a remote VHF station or no watts out.

I could calibrate it against a known good watt meter if need as that is
easy enough to do.

Or, could I convert it to a VHF 200 watt sensor as it looks like Elecraft
is not stocking them anymore based on trying to order a couple from the web
page.

The W2 is a great meter for remote operation and we actually use NodeRed on
a RPI to make it web readable.

Re: [Elecraft] W2

[David Herring]

Just to wrap up this question for the benefit of anyone else who is interested 
or may search for this later…

Jack’s response prompted me to go back and take a second look at the schematics 
for the couplers. Somehow I missed this the first time through, but it would 
appear that the coupler will provide a short to ground for a DC bias voltage by 
way of the secondary winding in T1.

So I’m going to take “no” for an answer here. ;-)  I don’t think the HF 
couplers will pass a DC bias voltage on through like I had hoped.

Re: [Elecraft] W2 Issue

[Jack Brindle via Elecraft]

Bill;

R22 in the sensors is a sense resistor that tells the controller which sensor 
is attached. It is a very low stress part that sees at most 5 volts at very low 
current. R22 is different for each sensor - the values shown in the schematic 
are not necessarily correct. Also, these are precision 1% resistors. With that 
in mind, the values are:
2KW HF Sensor, R22 is a 2K ohm 1% SMT resistor. 
200W HF Sensor, R22 is a 1KW 1% SMT resistor.
200W VHF Sensor, R22 is a 4.7K 1% SMT resistor.

We need to be careful what we might plug the sensor cable into. The standard 
box would not stress the resistor to the degree that the resistor blew, 
especially since that connector also has a ground attached as well. If it were 
to be plugged into something like an ethernet adapter, I would expect the 
sensor not to survive since those pins connect to entirely different signals 
with different characteristics.

[Elecraft] W2 Issue

[William Carpenter]

My W2 wattmeter suddenly stopped working properly this morning along with
that dreaded smoke smell.  The smell came from the 2KW sensor unit and upon
inspection R22 which is a 1K in the sense circuit is burned.  Of course
it's surface mount but I think I can replace it OK.  If not with another
surface mount I could possibly be able to mount a leaded resistor.  I was
operating at 100 watts on 20 meters into a low SWR when this happened.  Has
anyone else had this happen?  What could have caused this?  I have also
contacted Elecraft tech support about this but I know there are plenty of
experts on this forum too!

[Elecraft] W2 firmware

[Claude Cousineau]

Good day, I just purchased a w2 and followed the requested steps to install the 
new firmware V1.0 , now I don't know what was install from factory because I 
did not try it before loading v1.0 the power is about 10% low and swr is ok the 
problem is that the alarm won't work , on power on I ear the relay cycle , I 
made sure to enter an a in the utility program to get the answer a1 that tells 
me that protraction is on, but when swr is higher then 5 to 1 alarm doesn't 
trip the relay, I think it's a firmware issue! Does anyone have a previous 
version for the w2 so that I can try it? Thanks for reading this 73

[Elecraft] W2 software??

[Gordon LaPoint]

Hi,

    I run a remote setup.  I use the KAT500 and KPA500 remote software 
to see and control what the remote hardware is doing.  I have a W2 watt 
meter and was wondering if there is any equivalent remote software for 
the W2.


Thanks,

[Elecraft] FS New Elecraft W2 w/ 2 kW Sample Head

[Doug Hensley]

Re-posting this because I incorrectly described this the first time.

For Sale is my Elecraft W2 Digital RF Power Meter with one sampling head rated 
for up to 2 Kw.

The W2 can display zero to 2, 20, 200 or 2000 watts of outgoing RF power.  The 
package includes
the W2, the 2 kW Sampling head and the six foot CAT 5 or 6 (Elecraft P3/W2 
Straight Through Patch
cable) connecting cable.  I did not use this so do not have and cannot supply 
any PL-259 cables
for your K3 or K3S or whatever rig you are using.  Take a minute to read E's 
website description:

https://elecraft.com/collections/test-equipment/products/w2

The W2 today will cost $379 through their E store.  I am selling for $329 so 
you save $50.

If purchasing, please advise address, zip & contact number.  Shipped via USPS 
for $10.

Payment by simple check or money order preferred but you can add 4% for PAYPAL.
Note:  This email is NOT my PAYPAL account ID.  I will send that to purchaser

Re: [Elecraft] W2 wattmeter

[Don Wilhelm]

Joe,

The telling answer is in your statement "the radio has an internal ATU".
The radio is showing the SWR between the radio and the ATU.
The wattmeter is showing you the SWR after the ATU - in other words, the 
SWR of the untuned antenna.  So there may be nothing wrong.


Connect a dummy load to the wattmeter output and see what that reads - 
should be 1.0.

[Elecraft] W2 SWR Alarm Function - How to set?

[Andy Wood]

Hi,

I have a W2 that has not been used in some time. I tried it today and all
functions seem to work ok except I cannot set the SWR alarm trip point.

According to the manual sending a "]" increases the trip point and a "["
lowers it. If I send "]" I get back "]00;". Same response if I send "[".

Hoping it is something simple that I have overlooked.

I’ve done that literally thousands of times. You’ll need terminal servers.

Re: [Elecraft] NEW! DIGITAL DISPLAY UNIT for ELECRAFT W2 WATT METER!

[Keith Ennis via Elecraft]

 I've been asked about using the display unit for remote. Both the W2 and my 
display unit use a straightforward rs232 port. I haven't done it yet, but 
connecting 2 serial devices over the internet shouldn't be that hard.

[Elecraft] Elecraft W2 problem

[mike stokes]

Hi

 I have an Elecraft W2 and a HF 2kW coupler which I have a couple of issues
with and appreciate any thoughts.

#1 - When pressing the Range button the range cycles from 20 W to Auto.
When on Auto it defaults to 20 W until transmitting.  When in the 20W range
(or Auto) all of the SWR leds and the first power led light up.

#2 - When cycling through the ranges it skips the 2 W range.

I reversed the cable and reloaded the firmware with no issues,
Here is a link to a viedo showing what i am talking about.
https://1drv.ms/v/s!AtLmO2vBrPixk394MqxJ7BkwiV0w?e=2acerw
I appreciate any thoughts.

[Elecraft] W2 wattmerter not being recognised...

[Bill Steffey]

HI all,    I've just been wiring up my W2 wattmeters... and neither one 
is recognised  by my win 10 computer.


The USB to 3.5mm plug Elecraft cord works fine with my K3...  on com28

But the W2 utility keeps sending ": " at 9600 bps

and will not provide the current software level. with 1.0 being 
available.. ( maybe it is already at 1.0 ).



Then I want to run  The w2 interface software, but it says" "looking for 
a W2" , and on the setup screen   " w2 not found on COM28"   && "unable 
to open com 28"



I've verified the existance of com29 on device manager at 9600 & 
I've rebooted... I've even read the W2 manual several times. I used to 
have this working obn a different computer.  And can make it work on my  
toughbook portable.  I 've tried different usb ports on the main machine 
& com settings.


Ideas

[Elecraft] Elecraft W2 VHF/UHF Coupler use with 12VDC preamps

[SVangen]

It appears from the schematic that the Elecraft 144-450 MHz Directional
Coupler for the W2 SWR/Power Meter can safely pass DC voltage without any
direct interface nor danger of damage with the sensor electronics.  My
question, has anyone confirmed that the VHF/UHF couplers are safe to use
with 12VDC in-line coax powered preamps (i.e. Icom AG-25/35 preamps with an
Icom IC-9100 Sat Transceiver).
Thank you,
Scott Vangen WB0QMZ

Bill,

it can not be...

VHF sensor for W2 is 200W rated only.

HF sensor rated 2000W is 1-54MHz per spec.

[Elecraft] W2 Connection Issues

[Floyd Sense]

Thanks to all who responded on this and all is now working properly.  
Last evening, as I was pulling my hair out on this problem, the software 
suddenly recognized the W2 and I was in business.  This was after I had 
plugged/unplugged the W2 end of the cable dozens of times, reloaded 
drivers, etc.  At the time, I thought maybe the problem was a dirty or 
corroded plug or jack as the previous owner had never connected the W2 
to his PC.  After reading these recent posts, it's also possible that I 
powered down/up the W2 while the software was running.  At any rate, I 
cleaned the plug with DeOxit and inserted it several times into the jack 
and it's still working well.


I calibrated the W2 against my LP-100A and a setting of 498 on the W2 
resulted in about 5 watts difference between the two at the 1,500 watt 
level.  The difference at lower power levels  was a bit more or less 
than that depending upon the level.

It may be worth checking this about USB port power management.   This

Hi Jim,

If you figure it out please let us know. I have the same problem with a Win
7 machine. Everytime I start the software I must turn the W2 off then back
on for it to be detected even though the software sees the com port.

Subject: [Elecraft] W2 connection issues

I have two W2 units that I use with different K3's and different W10
computers.  One of them is reluctant to connect when I start up the W2
utility program.  So I power the W2 off and back on with the utility program
active and it connects just fine.  This is consistent behavior.

 

The other seems to be able to connect just fine.  I have not spent any time
trying to figure out why one requires the off/on sequence but just live with
it.

 

There may something in the physical connection to the computer.  i.e.
through a USB port, through a COM port, etc.

[Elecraft] W2 at 472kHz?

[eric norris via Elecraft]

Has anyone tested a W2 at 472kHz?  Does it work?  I would be putting 50w 
through it at that frequency using a transverter.
Thanks and 73 Eric WD6DBM

Re: [Elecraft] W2 Software

[Joe]

Now I'm confused.  The web site says that the W2 Current Production 
Firmware is V1.00, 4-12-2010.


When I look at my remote station using the W2 Interface Ver 1.12.1.18 
W4SMT software, the bottom of the screen says "Connected to W2 ver 1.07" 
 Why the difference?


K1ike, Joe

Re: [Elecraft] W2 Software

Thank you, David.

That is exactly what I am looking for. I am also thinking of writing a little 
utility to display the data.

On that page is a link that is supposed to go to a mod for the W2 but it goes 
to the serial interface commands file. I think Elecraft is having trouble with 
their new design. Oh well, they will get it fixed.

Hello Tim,

You are right. The W2 Utility is used mainly for updating the firmware. I 
believe you are looking for the W2 Interface software. The new web site doesn't 
appear to have a link on the software page, but by typing "W2" in the Search

Re: [Elecraft] W2 Sensor issue

[Bill Johnson]

I would suggest you may have a cable issue to test first. Try reconnecting the 
connectors.  And if you test at the site.  There are so many variables, we 
humans cannot help with being on site.  Take a few cell photos and then post to 
get help.

Subject: [Elecraft] W2 Sensor issue

I wonder if anyone has seen this before.

I was chasing a problem with high SWR on my 2K HF probe where on the radio, the 
antenna SWR reads 1.3:1 without the SWR probe installed and 2.9:1 with it 
installed.

Yes, I have changed my RG214 jumper cables to a few others.  I even replace the 
probe with a double female couple and the SWR dropped down to what I expected 
(about 1.3:1).

It is only on 6M that it has bad readings.   This is at my remote base, and
as I right this, I should have tested on a dummy load, but that will have to 
happen on my next trip.

So, as I asked before, anyone else see it fail only on 6m?

Re: [Elecraft] W2 wattmeter maximum Cat5 cable length

[Jack Brindle via Elecraft]

The cable is indeed not cat-5, but rather 8 individual wires that carry power 
and ground one way (to the box) and analog sensor signals back. The twist 
action in CAT-5 does not help here at all.
The things to watch for are signal loss due to resistance (shouldn’t be too 
bad, depending on the wire and length), and RF pickup. The latter can lead to 
bad and erratic readings.
The best advice is to keep the cable as short as possible.

Re: [Elecraft] W2 wattmeter maximum Cat5 cable length

[Dick Green WC1M]

Thanks. First real info I've gotten. I said Cat5 because the documentation 
mentions it and I believe it says you can use a standard Ethernet cable.

I haven't taken a close look at the coupler circuitry. If it's like most remote 
couplers I've seen, a too-long cable can cause a drop in the DC voltages that 
carry the forward and reflected power signals. If the coupler does a conversion 
to digital, then the cable length wouldn't be an issue. But that sounds pretty 
fancy!

[Elecraft] W2 wattmeter maximum Cat5 cable length

[Dick Green]

The W2 wattmeter comes with a 5-foot Cat5 cable to connect the coupler to the 
display unit. I need to use a longer cable, maybe 10-15 feet. I’ve searched the 
reflector archives and web for any information about the max Cat5 cable length 
but haven’t found any.

Does anyone know? Does the calibration routine in the W2 Utility compensate for 
different cable lengths?

Re: [Elecraft] W2 failure

[Michael Eberle]

Seems like I had a power connector issue with mine once. Using a 
different power cable took care of it.
One of the sensor lights should be lit.  If no sensors are connected the 
S1 and S2 lights will alternately flash.

Re: [Elecraft] W2 Wattmeter 440 band accuracy?

[Don Wilhelm]

Michael,

In general, digital wattmeters have the same accuracy at any point on 
the scale - unlike analog wattmeters for which the accuracy is stated as 
a percentage of the full scale reading.  On a 20 watt scale, a 25% error 
would be up to 4 watts!


You might want to look at the specs for that 440 MHz transmitter as 
well.  If it 2.6 dB or so, getting 2.8 watts out for a 5 watt setting 
may be what you can expect.


73,

There seems to be no problem on the 2 Meter band at only 25 % of scale (5

Re: [Elecraft] W2 Wattmeter 440 band accuracy?

[Philip]

That would depend on what kind of digital you are talking about. I don't 
think the W2 reads instantaneous peak power. That usually takes special 
circuitry to do . Hint: a digital slug for a bird 43 wattmeter costs way 
more than the meter does. Analog meters will not read properly in a 
digital environment. Try the radio in analog mode.

[Elecraft] W2 Wattmeter 440 band accuracy?

[Michael via Elecraft]

I just purchased a new Yaesu digital handheld and the power level on the  
440 band is low (2.8 v 5.0 Watts), and was wondering if I can trust the W2's  
accuracy? Another mobile higher powered transceiver also reads low on all 
power  levels on the 440 band.
 
I built the kit version of the W2 and have the VHF/UHF  coupler
 
Why is there a +/- calibration button on the PC interface if the unit is  
calibrated properly?
 
I can send my HT back to be tested and exchanged if it isn't making specs  
but don't want to be told that
my wattmeter reading was inaccurate!

Yes. It just takes switching the 8-wire connection to a new sensor with

I see that the W2 can support up to 2 remote sensors, selectable from the

Is it possible to support more (say 4 total) with some kind of external

I have a K3 with three XV series transverters (144, 222, 432). Each
transverter feeds a power amp and connects to an antenna for that band. I
currently use separate external meters at the output of each amplifier. I'd

Re: [Elecraft] W2 watt meter- multiple sensors question

[Don Wilhelm]

Dave,

Certainly, just find a switch that can switch all the wires of an 
Ethernet cable and you will be in business.
Of course, you would have to operate the switch manually unless you can 
come up with some scheme to operate the switch when each transverter is 
powered on.

[Elecraft] W2 Software

[Michael Walker]

To those who write software (not me.. .I just use it).

Is there any chance that we could have a 'compact' version of the W2
software display just like we have for the KPA500?

Just a thought.
