Well, this is not quick and dirty, but FWIW... WSPRnet is great for antenna comparisons. Write a script to switch your K3 between the two antennas at frequent known intervals. Run it over the course of days or weeks and you will have literally thousands of signal reports which, if you know

Regarding the K3, select an antenna, be sure RF gain is at max and turn AGC OFF. Set the display to AFV for a couple seconds. This provides a baseline value against which the DBV display is calculated. (This means dB in terms of voltage, not the traditional, standard dBv. Thus 2x the

Interesting question just popped into my head as I read this... Does the P3 follow which RX is selected? -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net For MixW support see; http://groups.yahoo.com/neo/groups/mixw/info For Dopplergram information see:

I'd like to do some quick and dirty comparing of antenna output signals using my K3 (and/or P3). (I've got two antennas I'd like to compare using different received carrier signals - e.g., from a neighbor's TX, W1AW RTTY bulletins, etc.) I see that the K3 can display the RMS value of

Hi Bill The P3 does follow the antenna you have selected. I just verified it again but I have a beam and a vertical and have compared them that way for years. The AFV function is set by the follow steps TAP DISP/METER Turn the B VFO nob to select AFV and wait several seconds for it to
