Hello Richard, Thank you for the input. It is certainly a circuit/image that will find its place in my LF folder! About the broadened noise pulses: Martin's loop has 8m^2 and produces a bg signal for
Dear Stefan, LF Group, In order to achieve one or two nulls using combined E- and H-field antennas, you need to be able to adjust the relative amplitude of the unwanted signal from the 2 antennas to
G'day, When I used to listen to the ZLs on 180KHz (15 years ago!), I used an active vertical and a loop combined in this circuit https://dl.dropbox.com/u/100084148/Phasing%20antennas.tif The circuit
LF, Currently i'm working on a E-H combiner together with Martin/YV7MAE in Venezuela. He has a well working E field antenna, about 80m wire, some m up, resonated with a ferrite rod and a variable tra
Dear Jim, Thank you for the comments, useful as ever. I know most of the needs you mentiond and also the problematic match. Well, certainly there is an advantage by using buffers to minimise the inte
