Hi audioguru and all o' ya... I think that the mistake I made initially was to assume that the schematic is incorrect and not the PCB. I built the whole project *on breadboard*, according to the schematic. I would suppose that this is why it wouldn't work. When dealing with such high frequencies such as 1MHz-1GHz, breadboard testing won't work... Fore sure, I know that there is an error on the schematic (D1 is used to label a capacitor) but I dont know whether the schematic was indeed the right one for this project. The strange thing is that when I checked the schematic on the 'Smartkit' website, I found the very same schematic for Kit #1154. Think I'll try a new approach and let you all know my results. Thanks again.. The Duke, South Africa
