Large Loop On The Broadcast Band
21 December 2014 | by 
Those of you following my blog will know that I spent some time this fall designing and building a large rotatable loop for LF and MF (BCB) work. So far the loop has met my expectations and is working well. In spite of several strong storm blasts from the southeast (70-90km), the lightweight PVC frame has shown little desire to grab the wind and destroy itself. For anyone seeking a simple and inexpensive method of mounting a rotatable loop or Flag type of antenna, I believe this mounting system would be excellent.
Over the past few weeks I have logged several new catches on the BCB with three of the highlights shown below. The two stations on 530KHz are both from Cuba...Radio Rebelde at 1Kw (Gauntanamo) and Radio Enciclopedia at 10Kw (Villa Maria). Note how the propagation this night almost puts the two signals, from opposite ends of the island, on a level playing field.
At the other end of the band, the Caribbean Beacon on 1610, from The Valley, Anguilla, has been making regular appearances with a strong signal as well.
A nice domestic catch was one-kilowatt CJEU, Radio Jeunesse in Gatineau, Quebec, operating on 1670KHz.
With the recent surge in solar flaring, the band has not been its normal December self over the past few nights...hopefully the sun will calm down and things can return to normal soon.
I vividly recall my excitement after catching WBZ-1030 in Boston, MA on my little 5 tube AC/DC radio and loose-coupled longwire. I had been hoping to catch an ID from them after listening for them for several Saturday nights! I even managed to get a QSL for my wall, similar to this one, shortly after the big event.
It's great getting back to my radio "roots" although DXing on the BCB has changed so much over the years, with fewer stations regularly identifying and no longer signing-off at midnight. Using the Perseus SDR has also made catching idents much easier, with the ability to record the entire band for hours at a time...or as long as one's hard-drive will allow.

Can I subscribe to your blog? I visited your blog page, clicked on the button at the bottom, but only got a page of jumbled text.
Must be over twenty years ago I made a loop for Medium Wave (the BC band) that was 300mm one foot square to a German design for listening to local radio stations across the UK. It was directional enough to let me hear stations on the same frequency but on different beam headings- I was able to hear Radio Orwell in Ipswich on the East Coast of England about 100 miles to the north east and Radio Victory in Portsmouth on the south coast of England about 80 miles to the south south west of me.
An old design similar to the frame antennas used years ago in portable radios before the ferrite rod became popular but very effective.
Terry…I haven’t ever checked that out but will look into it.

Terry…which method did you choose? I’m not sure if I can see the same thing as you since when I bring up my own page it basically shows me a bunch of edit options so I can reconfigure layout etc….not exactly the same as you see. Was it the ‘subscribe via e-mail’ or RSS feed? I noticed today, for the first time, a lot of hits arriving via RSS feed, so maybe you were able to do it?
