Thank you Don (W3FPR), Jack (K8ZOA) and Larry (N8LP) for your interesting comments on this thread last week and for taking the trouble to set them down so clearly.
My technical expertise in this area is no match for yours although I did make my first, fairly unsophisticated, indicator of forward and reflected power in 1967. In those days it was called a "Reflectometer" rather than an SWR meter - nothing to do with a Reflector of course :-) Since then I've used quite a few SWR meters of one sort or another and although a lot of technology has moved on beyond my understanding I've picked up enough to know that different meters will give different indications just as Don and Jack say. Some are, I think, better than others and I must admit that I have a good opinion of the LP100A but in my experience most of them agree within a reasonable margin of tolerance. Of course we could argue till the cows come home about what is a reasonable margin of tolerance and whether one meter or another falls within it (but let's not!). The reason I originally posted to the reflector was that the discrepancy I noted at 7.000 MHz of 1.2:1 on the K3 and 2:1 on two other meters was larger than I had come across before, and arguably outside that reasonable margin so I wanted to know what was going on. A number of suggestions have been made both on and off list but I'm still not sure. It would be interesting to know what indication the newly announced W2 would give, but we may have to wait a little while to find out. 73 to all Geoff G3UCK ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
