Raw footage and photos taken during the Fabrication of Transceiver #47 by N6QW, This is one amazing transceiver using four MC1496 Double Balanced Mixers. These devices are currently available at Mouser for about $0.84 a piece in single lots. This is a two band rig (40/20M) employing the Arduino/Si5351 and is a relatively small footprint. The IF Module, and circuitry for the Receiver and Transmit Mixers can be found in the Solid State Design for the Radio Amateur (pp 203- 205) with the Balanced Modulator and Product Detector from the Motorola Application Notes. A single 2N3904 is the Mic Amp and a 2N3904/LM386 is the Audio stage. The famous Plessey Circuit EMRFD Fig 6.110, is a combo Rx RF Amp and Tx Pre-Driver. A 2N2219A is the TX Driver and IRF510 the Final Amp.
The use of single sided copper vector board enabled rapid prototyping of the rig and lends itself well to providing a stable circuit.
