Many thanks Mike for the information. I have been doing some checks today and it looks like there are two possibilities,in fact both combine to give the poor result. 1)My recieving loop has a deep null in your direction 2) its quite a few db down on 73KHz. I hear HBG at S6, but using my TX Ant. its S9+5.There is not so much difference on 136 so the loop is considerably less efficient on 73KHz. I will look out for you beacon signal later and hopefully will be able to report better reception. 73s Laurie.
