| | ===== OVI40 SDR - how it started ===== |
| In 2015, the DARC local Radioclub OV I40 launched an initiative in which the [[http://www.m0nka.co.uk/|mcHF]] transceiver from Chris, M0NKA was built in Germany nationwide by radio amateurs and those interested in technology. The "networking" via our [[https://www.amateurfunk-sulingen.de/forum/index.php|Forum]] resulted in a rapid increased of mcHF builders. In our [[https://www.amateurfunk-sulingen.de/projects/projektgruppe-2#start|mcHF project group]], only about 20% of all bodybuilders have ever registered ... | In 2015, the DARC local Radioclub OV I40 launched an initiative in which the [[http://www.m0nka.co.uk/|mcHF]] transceiver from Chris, M0NKA was built in Germany nationwide by radio amateurs and those interested in technology.

| The OVI40-SDR is a transceiver covering the frequency range from VLF to FM. The project target is to enable everybody to build his own OVI40-SDR. Finished boards will be available to those who can not or do not want to build themselves a OVI40-SDR from scratch. The OVI40-SDR can also be built as a pure receiver (for those who do not yet have an amateur radio license and thus are not yet allowed to send). It can then be easily extended with transmit components later to become a full-fledged transceiver. | The OVI40-SDR is a transceiver covering the frequency range from VLF to FM.

| The development team is based on existing commercial and self-construction projects and combined from a variety of devices (and great features) each best in the newly created OVI40 SDR. The project should not be "just" an amateur radio transceiver - it should be a philosophy. Technically interested people from all over the world, with expertise from different areas, with different mother tongues, religions and at home in different political systems meet to create and promote something together, for their own benefit but also for the benefit of all who will join the project later.
