A view looking toward \u00a0Oxford Shortwave Log<\/a>\u00a0DX’pedition territory; a wood in rural Oxfordshire<\/p>\n

Regular viewers of my youtube channel will know that I spend much of my shortwave listening time out in an Oxfordshire wood where QRM is negligable and Tropical Band stations can be heard with, at times, unprecidented signal-to-noise. Regular viewers will also be aware that I enjoy experimenting with different antenna set-ups, particularly pushing the boundaries with longwires coupled to\u00a0portables. Having applied my rather modest practical skills, I constructed a 200 metre deployable 200 metre longwire antenna and finally got around to testing it, with my Elad FDM DUO and Sony ICF-2001D. There are a number of reception videos still to be uploaded to the Oxford Shortwave Log\u00a0youtube channel, howvever, the immediate information and entertainment of SWLing Post readers, I have included two here. \ud83d\ude42<\/p>\n

The first is the more\u00a0commonly heard\u00a0Emisoras Pio XII from Boliva on\u00a05952.5 kHz using the Sony and the second, the much more rarely reported\u00a0Radio Chaski from Peru on\u00a05979.9 kHz using the Elad. Both reception videos were very encouraging. In fact, I would go so far as to say they demonstrated excellent reception witihin the framework of their respective\u00a0contexts. Emisoras Pio XII was almost booming with unprecidented signal strength and clarity, whilst Radio Chaski was heard with discernible audio. Neither station had been received\u00a0as well at my QTH or the woods, previously.<\/p>\n

I hope this gives other DXers ‘food for thought’ with regard to experimenting with antennas and perhaps more importantly, making significant improvements to\u00a0SNR by removing themselves from the ubiquitous blanket of QRM generated by all of those devices at home that are intrinsic to\u00a0modern life. Thanks for watching. 73.<\/p>\n
