Thank-you for the signal strengths and frequencies, Paul. Sorry if this messes up your efforts to relate 3600 metre TA propagation with ionopheric electrons, Alan! It is interesting indeed. It may take a rewind to get the coil back in service. The new coil (0.14 H 57 Ohm) works well, but the older one (.27 H, 94 Ohm) started sizzling, sparking and smelling of ozone when the new coil was added. The higher current (0.34 from 0.28 A) and some design flaws caused the failure. The total inductance to tune the 10x100m rotated L aerial was 0.48 H tuned by mutual inductance between the 2 coils. 73 Joe VO1NA On Sun, 18 Jun 2017, Alan Melia wrote: > iHi Paul and Joe.
