Chameleon EMCOMM 3 Base Short 20M WSPR run

For several months I’ve had Chameleon EMCOMM III Base antenna, up on the tower, in a sloping configuration. The transformer is at 12m (~40feet) height sloping down to about 1m (3feet) off the ground, NNW ~320° azimuth. The ground lug terminates onto the tower.

I’ve been using the antenna system from my home qth, replacing the terminated dipole (for the moment). HFAPRS, FT8, WinLink, … all with great degrees of success.

SWR is relatively flat across 20m with a 1.3 at the bottom of the band, to 1.6 near the top band edge. So I didn’t use a tuner for this test.

If you’d like to see the entire SWR plot across HF, check out the original post here.

WSPR results were quite astonishing.
nearby stations in Scandinavia came in as expected. European stations were all strong and easy to hear. the oddballs were Japan, Eastern Russia, and South Africa. I’m not quite sure of the path considering my slopers pointing towards North and South America.

  • On day 1, the test started at 2018-05-01 09:06, ending at
    2018-05-01 09:14.
  • Day two started at 2018-04-30 11:28, ending at 2018-04-30 11:48.

The farthest station spotting my beacons was ZS6KN in KG44bj, at a distance of 10,089km (6269,014 miles).
2018-05-01, 09:06, OH8STN, 14.097106, -23, -1, KP25qc 5w
ZS6KN, KG44bj, 10089, 178.

So far so good with the antenna.
