WSPR Antenna

One aspect of WSPR which could be improved upon is an up-to-date profile for the antenna(s) currently used by operators WSPRing or spotting. For example if I’m using the www.dxplorer.net or www.WSPRnet.org to compare an operators results to my own, knowing what type of antenna the operator is currently using, would help me better understand the comparison results. It would also be useful to know what type of antenna was used by a station spotting our beacons.

To help aid others with their comparisons, I’ve started keeping a near real-time log of the antennas I have in WSPR use.

Working with the Super Antenna MP1 in Lazy L configuration.

I’m running the WSPRLite on 20M using 200mw. The horizontal element is South by Southwest with a vertical element at a 45 degree angle.

I’m currently on 30m testing the Chameleon CHA TD (Broadband terminated dipole). I’m using the SOTABeams WSPRLite @ 200mw output.

01 June 2017

Currently testing 2x WSPRLite

  • OH8STN TX only: Super Antenna MP1C on 30m. The MP1 is mounted on the SuperPod tripod and uses the 4010 counterpoise kit.
  • OF8STN TX only: Chameleon CHA TD Broadband terminated dipole. Broadband terminated dipole. One leg is Southwest, the other leg is North-North-East. The center portion is at 12 meters height from the tower stand-off. I’ve also corrected a configuration issue with the counterpoise. They are not lated flat along the ground, bringing swr down to a nice level on 40m.

  • OF8STN TX only: Broadband terminated dipole. One leg is Southwest, the other leg is West. The center portion is at 12 meters height from the tower stand-off.

Currently testing 2x WSPRLite

  • OF8STN on Chameleon P-LOOP 2.0
    (Booster kit and tuned coupling loop)
  • OH8STN on Chameleon F-LOOP+ 2.0

22 May 2017 OH8STN TX Only:
Currently testing Chameleon F-LOOP Plus 2.0 on 30M with WSPRLite @ 200mw.

16 May 2017

  • OF8STN RX/TX:
    Chameleon P-Loop 2.0 with optional Booster kit. The loop is tripod-mounted with its capacitor at 2 meters height. It’s being powered by the FT-817NND @ 500mw.
    The loop is mounted indoors under the rafters of the attic in my garage.
    Loop is oriented West Southwest.

I’m running two WSPR beacons with two unique callsigns.

  • OH8STN TX only: Broadband terminated dipole. One leg is South by Southwest, the other leg is West-Northwest oriented. The center portion is at 12 meters height from the tower stand-off. Driving the Broadband terminated dipole is a Yaesu ft-817 at 500mw, controlled by wsjt-x on Ubuntu Linux.
  • OF8STN RX/TX: Chameleon P-Loop 2.0 with optional Booster kit. The loop is tripod-mounted with its capacitor at 2 meters height. It’s being powered by the SOTABeams WSPRLite at 200mw. The loop is mounted indoors under the rafters of the attic in my garage. Loop is oriented Southwest/Northeast.
