catman Posted June 25, 2017 Share Posted June 25, 2017 G'day all, well it's been a slightly annoying day as I've spent a fair bit of it in trying to prototype a simple AM receiver using an MK484 TRF radio chip. I've built these before with no problems but today....no success at all! I did hurriedly put it together but as far as I can tell there are no wiring errors, but the damned thing won't work (at all). Grrrrr. Ever have a DIY project like that? Regards, Felix. Link to comment Share on other sites More sharing options...
mwhouston Posted June 25, 2017 Share Posted June 25, 2017 @catman try another radio chip. I had a OPA627 preamp which just stopped. Strangely both chips failed. Dropped in some OPA222 and it all worked. 1 Link to comment Share on other sites More sharing options...
