hi I have velleman MK194N FM radio kit and it is not working l do not have any solder bridges and believe it is all correct but when l turn it on l just get a slight sound as though it is trying to working but not even the LED is lighting up if l have put the LED in wrong would this stop it from working l would like to point out l am new to this although l have made the odd items back in the 70 when l was a ham radio operator

would love to hear your thoughts

elenco.com i was told to contact them it seams l am been moved from of place to another all l want is the RA1 10k resistor l feel l am been let down between your copy and the Elenco where l bought it from if l had known it would cause this many problems l would never have bought it

if you can send me this resistor for the FM Radio kit that should sort it out

Hi @Allan6, we cannot be sure the resistor alone would fix your problem, that’s why we ask you to contact your seller to organise a return so we can examine your build kit. We really want to make sure we understand what is wrong with your kit.

We understand it’s a lot of work from your side, but it’s the only way we can guaranty the quality of our kits. I hope you understand.
Kind regards,
