Many thanks to those who replied to my request for assistance with the SMD kit. 
 M0FMT has kindly offered to help.

Mal: thank you for offering a kit suitable for conversion to 500 kHz, but my 
main interest is 136.  Even though I am in the heart of rural Burgundy, I seem 
to be plagued by a high noise level at the bottom end of medium wave.  I wish I 
hadn't given away my B41.

My e-mail system has been giving problems over the past week or so.  Has anyone 
posted anything here, or sent me anything direct which needs a reply from me, 
please?
