Phoenix 612: Receiver PoC SA612 Test
Channel: Dave VE3OOI

The Dueling 612 (D612) Transceiver was abandoned due to the purity of the output which did not meet Industry Canada requirement for spurious emissions.  The receiver sensitivity was also not that great and a resigned of the transceiver was necessary.

The Phoenix 612 has risen from the ashes of the D612.  

This video is one of a series that summarize testing completed on the Phoenix 612 redesign.  A key part of the redesign is generation of Proof of Concept (PoC) boards to test aspects of the receiver and transmitter.  

Initial PoC Rx and Tx boards were created and submitted to JLCPCB.  This video summarizes initial testing on the PoC Rx PCB.

Notes:
1) I'm using a 50R Sig Gen source that feeds 1500R SA612 input, and feeding a 50R Spectrum Analyzer from 1500R SA612 output.  Impedance mismatch will cause reading to be off
2) I'm testing the second SA612 which converts IF to audio via a BFO for Rx as well as converts IF to RF during Tx.  This test demonstrates both.
3) The IF for this current design is 12 MHz.
