The Mini-Kits EME205 9MHz BFO Demodulator Kit is part of a building block to construct a high performance M1 Series HF Transceiver.  The module board is designed as a 9MHz I/F SSB and CW demodulator, and uses a SA612 Gilbert Cell Mixer to demodulate the 9MHz I/F down to a filtered audio output. The module includes an on board Beat Frequency Oscillator BFO, that uses switched multiturn trimpots to set the carrier frequencies for CW, LSB and USB. The BFO is also available as an output on the board for connetion to to the M1 Series EME208 SSB modulator which uses the MC1496. The module has been specifically designed as a building block for the Mini-Kits M1 Series HF Transceiver, but is also ideal to construct you own Receiver or Transceiver design.

For more detailed information on how this module Kit can be used, Please refer to the EME205 Kit webpage.

This Kit is ideal for all constructors mainly due to the use of conventional leaded components.  Only a very small number of surface mount components have been used due to component availability.  The basic Kit includes the PC board and all onboard components, but excludes the SMA connectors which can be purchased separately if required.

For the highest performance and reliability, Only high quality first grade components from large suppliers in the USA, or direct from major manufacturers are used in this Kit.
