Errata for Ensemble II VHF RX (BETA) 03_Local Oscillator/Control page
- Hello Everyone,
There is an oops in the illustration for the transformer continuity test in the local oscillator section on the Ensemble II VHF RX (BETA) 03_Local Oscillator/Control page. The text indicates that you should be able to measure continuity between points A and B (the USB ground pin). The marker for point B is off to the left of where it should be. There is no connection between the USB shield and the USB ground pin. The correct position for point B is (looking at the bottom of the board, with the USB connector on the lower right side) the bottom left pin (pin 4) of the USB connector. If you look close you will note that this pin is directly connected to the isolated USB ground plane on the pcb.
The Rx resistor referenced in this section has also been relocated and is now relabeled as R28 in the latest version of the board.
I have also sent this information to Robby and have every confidence that he will include the change in his next update for the build instructions.
