 ====== Integrated 10 GHz Beacon Transmitter ======
-After the decline in use of ATV in Germany, an idea of building a 3 cm beacon at [[https://db0hdf.de/service-beacon-10g/|DB0HDF]] emerged. A survey of the equipment landscape revealed some shortcomings: Currently, no commercial all-in-one 10 GHz beacon transmitter is available. Documented designs exist, but often are built from a) many individual components (tin-can style) and/or b) obsolete and unavailable parts.
+After the decline in use of ATV in Germany, an idea of building a 3 cm beacon at [[https://db0hdf.de/service-beacon-10g/|DB0HDF]] emerged. A survey of the equipment landscape revealed some shortcomings: Currently, no commercial all-in-one 10 GHz beacon transmitter is available. Documented home-brew designs exist, but often are built from a) many individual components (tin-can style) and/or b) obsolete and unavailable parts.
 The goal of this project was building a 10 GHz beacon transmitter suitable for long-term unsupervised operation from commercially available integrated circuits. To make full use of the transmit power constraints in Germany, an output power of 1-2 W was targeted. Support for contemporary digital beacon transmission modes such as [[https://rudius.net/oz2m/ngnb/pi4.htm|PI-4]] was also a requirement for the design. Remote monitoring (telemetry) and control functionality was the third critical item on the feature list for a complete design.
