A project of German CRP Club DL-QRP-AG: The Black Forest Transceiver.
This is an allband Shortwave Transceiver SSB/CW with plug in Band Modules. What we tried was to design a cheap but TOP Transceiver. To make it cheap, we use the Plug In Bandmodule Technic. To make it a Top RX we use a variable pre-Selector for each band, a +7dBm Mixer and a DualGate MOS IF Amplifer. The TX is using a variation of our push pull 10 Watt DL-QRP-PA.
