[Hybrid tellies]

Thanks for the suggestions. Yes Paul I did go Grrr, very loudly. I did use 693Khz from Droitwich but this signal in our office is much weaker and reqires that you sit by the window to hear anything.
I bought this cheap little radio possibly from the 1980's because of its small size so it could fit in my limited office storage unit at work and of course because it was only £2.
You have all persuaded me not to bin it but to take a look. I have also noticed the battery terminals are rather corroded which explains the other fault of intermittent cutting out. I shall let you all know in the not so distant future what I find.
