Hi there, further to my previous post regarding the initial testing of the Medium Wave Circle-design 200 metre Beverage antenna at the woods in Oxford, UK, I am pleased to share further reception videos for both the medium wave and shortwave bands. For medium wave, I operated the FDM DUO via a laptop and the FDN-SW2 software, recorded the entire band at the top of the hour and retrospectiively analysed the signals. For shortwave I utillised the FDM DUO as a standalone receiver, routing the audio via the excellent Bose Soundlink Mini 2 speaker.<\/p>\n

As a quick recap, the antenna was terminated at the ‘front end’ with a 650 Ohm resistor into a 1 metre-long, permanent copper earthing rod that I had previously driven into the ground, away from the route taken by the general public. The actual wire was orientated in a generally westerly direction, and thus nulling signals propagating from the east. At the receiver end, I utillised my self-built transformer, wound for a 50 Ohm input impedance (14 turns on the primary), thus making the entire set-up suitable for the Elad FDM DUO. It was quite a pain to set up, taking over an hour to deploy, however, the results\u00a0were very promising. A scematic diagram follows below.<\/p>\n
