I also compare reception of the same station with the Degen DE1103 PLL using the 3.5mm input. The Degen DE1103 still had better reception even when I used the whip antenna extended at the very minimum when using the LW\/MW external antenna trick. I know I should have used the internal ferrite antenna of the Degen compared to the D-808, but in any case I did try off camera &amp; reception was about the same. So unfortunately the D-808 was never going to win this round.<\/p><\/blockquote>\n<p><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"625\" height=\"352\" src=\"https:\/\/www.youtube.com\/embed\/ctaONkpJ3CA?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span><\/p>\n<blockquote><p>However, there is a solution.<\/p>\n<p>The answer? Build yourself a Long Wave induction antenna <a href=\"https:\/\/youtu.be\/YZPZyxozFPc\" target=\"_blank\" rel=\"noopener\">as shown in the second video<\/a>\u00a0[below]. I made one some time ago, as I grew frustrated at how poor the Tecsun radios were on this part of the band &amp; that there were no LW induction antennas available to buy. I tried a signal on 207 kHz which is R\u00daV R\u00e1s 2 from Iceland. Either a radio with a very good internal antenna or a good external antenna is needed to receive this station at my QTH in southern England.<\/p>\n<p>Placing the D-808 on the induction antenna resulted in a very pleasing result, which was it did get reception of Iceland on 207 kHz. So this shows that it is possible to DX on the LW bands with the D-808 with some &#8220;external help&#8221;.<\/p><\/blockquote>\n<p><span class=\"embed-youtube\" style=\"text-align:center; display: block;\"><iframe loading=\"lazy\" class=\"youtube-player\" width=\"625\" height=\"352\" src=\"https:\/\/www.youtube.com\/embed\/YZPZyxozFPc?version=3&#038;rel=1&#038;showsearch=0&#038;showinfo=1&#038;iv_load_policy=1&#038;fs=1&#038;hl=en-US&#038;autohide=2&#038;wmode=transparent\" allowfullscreen=\"true\" style=\"border:0;\" sandbox=\"allow-scripts allow-same-origin allow-popups allow-presentation allow-popups-to-escape-sandbox\"><\/iframe><\/span><\/p>\n<blockquote><p>For anyone interested making a LW induction antenna as shown above, <a href=\"https:\/\/youtu.be\/BaDSb8GiECY\" target=\"_blank\" rel=\"noopener\">here is a link to a video<\/a> that has basic instructions &amp; further results.
