24 hours of spots of KB1KXL, ending 0020 UTC 2/8/2017.
I think that my antenna is to blame for the lack of results in those directions. It is a low (~15 feet) doublet, cut for 40m, and in an inverted-V configuration. I'm feeding it with 300 ohm twin lead, which has to pass through a metal window frame. I also have to keep the feedline low in some rose bushes until it gets to the antenna tree so that it can pass under the power lines. Also, one of the legs passes through a few trees. The tuner in my KX3 is able to match it on all bands 80-6. My guess is the low height and all of the compromises I had to make in order to get it up are limiting the range and ability to hear dx. To upgrade I'm going to try running some small coax through the window to a balun outside, under the theory that it will reduce losses while going through the window. A more difficult upgrade is to get a tall pole to support the center of the antenna.
Using the online VOACAP modeling for coverage area, it looks like I can get some improvement from going from a dipole at 5 meters to one at 10 meters.
Dipole at 5 meters (17 ft)
Dipole at 10 meters (33 ft)These plots were generated on 2-3-2017 at 0100 UTC, location Sacramento, 5W, CW, on 40m. All others settings were left at the defaults.
At some point I'll switch the Ultimate 3S over to QRSS and see how that does. I'll post an update with some results when I do. Next I need to get the Raspberry Pi set up with a sound card so I can have my own WSPR/QRSS grabber...
