Oscar 100 upconverter

AMSAT-DL has produced a small up-converter design that can use either 70cm or 23cm input and produce 6W direct from the board at 13cm. This is quite enough output for CW/SSB in most cases. It can also take a reference frequency from an external source.

At 189.5 Euros this looks quite good value. It means a whole Oscar 100 station could be put together for far less than an HF transceiver. I am not sure if these units can be obtained ready built.

The geosynchronous Oscar 100 has been up for about a year now.
