Hello Allan,

Having first started to make MW and LW loops of many shapes and sizes, some 65 years’ ago, I found your idea interesting. However, it’s a pity that you didn’t state the dimensions of the cardboard box employed.

Just now, I’m thinking of making an LF loop to cover approximately 60 to 80 Khz, so I wonder if you or any of your readers has tried to do so, too and if so, with what results? I need such a loop, to improve my reception of a couple of TX’s –one in the UK and the other in Germany– which broadcast time signals derived from an “atomic clock”.

At 80 years’ of age and long retired, I now have little test gear left, even less patience and my eyesight is awful.

Therefore, any relevant information would be gratefully welcomed.

Keep up the good work!

Cheers!

Jim.

Hello all good.

I found this very good idea of your antenna cardboard box, so when you put more projects on the site is always good to have news.

I would like to visit my blog and make a comment, thank you

I have considered building a loop antenna that is wired in place of the ferrite rod antenna of a PLL tuned radio ie tuned by the varicaps of that system.

Is such an antenna possible/practical?

Preferably it could be plugged in as needed, replacing the ferrite rod coils.

Regarding 702 Sydney, I listen to this at night at Wollongong and find that it fades regularly.

The solution is to also have 738 as a preset and alternate as required - one is usually clear.

Also ABC news radio 630 is interfered with at night by local radio from North Qld on the same frequency - wipes it out sometimes. This is slightly improved with careful orientation but as the Gong, Sydney and Townsville are more or less in a line great improvement is not expected. Is there an aerial that would cut out the sky wave from Qld? Otherwise will have to go digital and I object to the heavy current draw of digital.
