Transceiver Architecture 2.26 07/03/2017 Yesterday we swapped out the 12.7 MHz filter pair for ones operating at 16 MHz as we suspected there was an issue with the 12.7 MHz USB filter (actually the LSB Filter --sideband inversion). I also opened up the tuning range so that the rig will tune from 300 kHz to 30. MHz which now lets me check out the performance across the HF ham bands. While tuning 15 Meters I ran across one of the Thirteen Colonies Special Event Stations. I made a short video of that station. The configuration is a the MMIC as the RF amp stage, no band pass filter and just the two Plessey amps. The Mixer and Product Detector are ADE-1's. Houston we have ignition, the bird is flying! Today I wired up the Si5351 board plus the display and that worked well. Here are some snaps of the assembly and while I was at it I used the FFT function on my Rigol DSO to look at the outputs from the two clock generators. I was pleased.
