I have used like this, but with agc always off and filter from wide to narrow settings depending on usage, i.e. dxpedition narrow on qrg etc.# Indicated waterfall audio freq is added to vfo freq to spot, i.e.14070 & 1500hz for 14071.5 etc. > It > always seemed that there were two flaws in this: One was that it was not > easy to pick the actual signal using the P3 markers, you always were using > the USB lower frequency point that was some number of hz away from the > signal.

Today I played around a bit. For one, I used the manual notch filter to remove a really strong signal. I turned of AGC. This works well. I also set the radio in DATA mode instead of USB. The nice thing about this, is that I can use the P3 with a +/- 2 KHz span, and see all of the signals in the usual PSK range, but now I can click on one I see, and it will actually center it in the passband and give me a frequency readout that seems better than the standard 14.070 for 20m. Furthermore, I can use a narrower filter and the reception seems much better and the decoding more accurate. So my question is, is my new found way of using the K3 a better way and possibly the best? Thanks for any insight.
