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 stablaize. Turn the VFO B to dBV I just tried that again and my vertical measures +.05 dBV and my beam measures -2.6 dBV both looking at 20 meter noise and the ATT and PRE set the same for both the REG and RX ANT. I hope that helps you 73 and good luck Ken W0CZ w0cz at i29 dot net Sent from my iPad > On Sep 28, 2015, at 9:47 AM, David Cole <[email protected]> wrote: > > 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: > http://groups.yahoo.com/neo/groups/dopplergram/info > For MM-SSTV see: > http://groups.yahoo.com/neo/groups/MM-SSTV/info > > >> On Mon, 2015-09-28 at 07:39 -0700, Bill Conwell wrote: >> 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 receiver AF output (mVp-p), >> unaffected by AF GAIN control.
