QThankyou for your previous reply about the coil.
With an MK484, a thicker wire coil I wound onto a ferrite rod, does produce medium wave signals, with a 500 pf variable.
But this coil I bought and tried doesn't seem to amplify anything - I connected terminals 1, 2 as mentioned, as in the data etc. even with a wire out the window connected to one end of the coil. The length of the coil conducts, checked with a meter, from one soldered terminal to the other(s).
The input impedance of the MK484 is high - 4 megohms - is this the problem perhaps? Thankyou.
Hi Harry, thank you for your question. 4 mega ohm is about right for the input impedance of a MK484, unfortunately we cannot undertake design work or fault finding for you but offer generic advice. I found this useful link with lots of information you might find useful.

QHi, are the ends of the copper wire tinned? Thanks
Hi SJ. Thank you for your question. The copper ends of this aerial are tinned.
