|UNIQUE reports received on 15m baseline earth-electrode antenna on 474.2kHz WSPR|
17 Feb 2014
Overnight my transmissions with the 15m baseline earth-electrode antenna continued. A couple of reports from Holland were added to the list of spots bringing the total UNIQUE station reports to eight. The only change has been to resonate the loop with a small series inductor. This increased the loop current by about 20%. Next to try will be to see if the 50 ohm match can be bettered with a small auto-transformer. I suspect not, but we'll see.
