HF RFI Jan 2, 2012 - WebCam samples on FT-847 with 20-m and 40-m fan dipoles in AM mode, 10-8 MHz and 15 and 20 MHz. There is a c. 80-kHz periodicity to the RFI peaks. Strange how it greatly drops off near 8 MHz as one would expect my 40-m dipole to have more gain there than near 10-MHz. There is no apparent sudden dropoff in the 10-25 MHz range (samples for 15 and 20 MHz). Other details of this puzzling RFI at http://lists.contesting.com/pipermail...
