\"2-jungle\"<\/a>Recently I have spent a little more time\u00a0listening out for\u00a0Tropical Band stations from my shack in Oxford UK, attempting to emulate some of the very nice signals I have previously recorded out on DX’peditions. The obvious problems with this (and they are numerous) include the relatively weak signal strength of many tropical band stations, the ubiquitous blanket of QRM, resulting in generally poor SNR, lack of space for a large antenna……need I go on?! Fortunately, the Elad FDM DUO has proven to be a very senstive and selective receiver, capable of, at times, incredible SNR, coupled with almost limitless signal conditioning options and SSB, SYNC, ECSS etc. Throw\u00a0the Wellbrook ALA1530 active loop into the mix (not literally!) and you have a very powerful Tropical Band receive set-up. The Wellbrook is able to null most (although not all) QRM in my shack and that really can make the difference between simply observing a carrier and actually hearing audio. Clearly one cannot expect to hear DX at home under heavy QRM as well as you might outdoors, however, the following stations were logged in the past month or so, with respectable signals, with the ALA1530 indoors:<\/em><\/p>\n
