Good Morning Eric
I have tried with all 3 combinations .. .. IC on it's own; IC removed and link in place; IC in place and link ; None of those combinations make any difference at all.
The only reason I was looking at the 'bodge' repair was because I couldn't find a replacement TLE 9413 anywhere. However, I have now found one at Farnells Element 14 site, in fact they have thousands of them, and I'm just trying to get CPC to obtain one for me, because I have an account at CPC but not with Farnell. I've also ordered a new battery because the charging cycle seems to have a problem - probably due to a thermistor in the battery pack. Still much work to be done it seems .. .. the chances of my getting a cheeseburger out of it are getting more and more remote.
DAB radios .. .. .. . I've finished my little foray into that world for now .. .. I bought a book about Circuit Analysis and quickly realised that to make any use of it I needed some circuits to analyse ! A bit logical for me, I know, but there you go .. .. .I found a guy on Ebay selling DAB radios in lots of 4 as faulty .. so I bought 4 .. .. worked out at 99p each and I was able to locate a PSU problem with all 4 so I repaired them - what a buzz I got out of that ! So I bought 4 more .. .. but only 3 were PSU problems, 1 had a signal process problem that I couldn't follow. I ended up having bought 11 and repaired 9. The repaired ones I gave to the local BHF charity shop and he has one in his window at the moment @ £25 .. .. of the 9 he has 2 left as at last Wednesday. The other 2 I cannibalised for useful bits and binned the rest.
I'm busy building the boards to do NGs ASM tutorials at the moment, in between all the other things my senior manager keeps finding me to do. My next project after that is a digital sense of humour detector based on a PIC 16f14U, a flip-flip and a flop-flop outputting to a duck converter.
Thanks for your support Eric, much appreciated
