Improved version of our popular upconverter!SNR greatly improved over previous versions by revising the filters and LO to operate at 125MHz so as to move away from the FM broadcast band. Further improvements were made via component selection to improve your listening pleasure with no increased cost over our previous models!Ham/amateur radio enthusiasts rejoice! Our MF/HF converter for software defined radio is finally available for sale. This device allows you to listen to MF and HF through your existing software defined radio (SDR). If you do not currently have an SDR we have plenty of low-cost solutions available for sale.BONUS! We had space left on the PCB, so rather than waste it we have added a noise source circuit at no additional cost! We have even populated most of the components for you. We have kits of the components required to complete this circuit available for a small additional fee. Details of the noise source circuit are available with the project documentation, and a detailed image of the circuit can be seen in the pictures above. Full operating instructions are available on our website nooelec.com
