Dear LF Group, I have now finished my 73kHz loading coil, and some preliminary tests last night seem to show that it works OK. The set-up is basically the same as that for 136k, except that the anten

Dear LF Group, Was very interested to read G3LDO's piece about antenna comparisons - it seems that the most important factor for DX operation on 136kHz may ultimately be the ground, rather than the a

Dear LF group, I don't have any strong local signals close to the 136kHz band - the problem comes more from the MF Transmitters across the road, which deliver a watt or so of BBC radio 5 on 909kHz to
