Hello Tony, LP100A from Larry Philip, which is a vector power meter, will fulfill your requirement BUT it is more expensive. I have both LP100A and W2.
Since LP100A does not have a V/U coupler, I get my W2 to cover the V/U band segment. Bird meter is so called the industrial standard (if well calibrate), I would prefer both LP100A and W2. These meters are at least as accurate as the Bird. 73 Johnny VR2XMC ----- 郵件原件 ---- 寄件人﹕ k2zls <k2...@optonline.net> 收件人﹕ Elecraft@mailman.qth.net 傳送日期﹕ 2010/2/22 (一) 11:14:15 AM 主題: [Elecraft] W2 Wattmeter wish It looks like the W2 is well on its way, but I just wanted to present my case why I can't buy one. The display is just not presented accurately enough for me. It takes a computer link to present the info in detail and thats not what I envision doing. It seems that the info is there in the box almost down to the watt, but you can't be sure what your power is squinting at a bar graph to tell you that you are somewhere within 100 watts of your target. To my way of thinking it's only relative info. Not good for me. Here's what I would think would be a KILLER that I would buy in a minute. I would like to see two windows of 7-segment GREEN LEDS. (Thats 4 characters XXXX) to display the forward power and another window to display the SWR. (X.XX) These LEDs would be large enough to read across the room. I would then buy two directional couplers. A low power at 200 watts is more than enough for the input side of the QRO AMP and another for the output side at 2500 watts. That way both sides of the AMP can be monitored with just one press of the sensor switch. But, thats something you can already do with the current configuration. The real deal is observing the actual power out of the amp and SWR. The current bar graph would supplement these windows and provide and easy way to see the trends while tuning. There are other units out there that are, perhaps, more accurate and even present FREQ readouts, but the main problem with these is all the info is cluttered on one screen which is hard to decipher. I like the W2 format but, it just needs to be taken to another level. LEDs would really standout and should be able to present the info as accurate as the computer. Thanks ELECRAFT and I hope it continues to keep getting better. 73 Tony K2ZLS ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
