Apparently I need some help in trying to use this dBV capability with on the air signals.
For example, using it as an AGC off "relative" S-meter with digital readout to run some antenna pattern checks for skewness etc. I've used it just fine in "lab type" measurements with a constant signal source. First question. What is meant by stable value of AFV? Here's what I see for a bunch of AFV edited values one after another with no change in K3 settings. 1579,1688,1598,1624,1696,1613, 2168,1758,1425. The range is 6db. Is the reference value of AFV used in the dbV calculation the last one taken at the instant one leaves the menu entry? Yes, it doesn't really matter if that values is used forever. Suppose one then takes a series of dbV measurements, is the reference AFV ever changed during the set of readings? The integration times available are 500 and 1000 ms. It would seem that longer integration times are required for off air type measurements. Is there any integration time in the measured voltage used in the dBV calculation? Or is it nearly an instantaneous value? For off the air type measurements, it would seem that a suitably long value is needed. 73 de Brian/K3KO -- View this message in context: http://n2.nabble.com/K3-dbV-in-2.38-tp1092599p1098058.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
