About 30 watts were fed to a 5:1 XFMR and a ~0.35H tuning coil to the 100m wire at 10m height. CW signals were heard clearly at 2 km using a homebuilt DC RX and a PA0RDT miniwhip at 2 km. The sigs could not be heard on the DC RX at 2.7 km and were much weaker on the XH100/LF10 with 20m of wire strewn in the trees. This is a new distance record for me for audible reception at 8.277 kHz. The ERP was about 3uW. 73 Joe VO1NA
