| R6 and R11 were initially replaced with 510 Ohm resistors to make the board controllable by the 3.3 V GPIO pins of the Ettus USRP X300 SDR. These have since been put in series with a 10k resistor (currently jumping the feed connector) since it is running on 26V again. | R6 and R11 were initially replaced with 510 Ohm resistors to make the board controllable by the 3.3 V GPIO pins of the Ettus USRP X300 SDR.

| - | As for the rest of W1XM the default state of the LNA protection relay at the feed is the transmit state (in which the LNA input is isolated from the feed). To be able to receive, the bigdish sequencer MUST be in the receive state. | + | Like the rest of W1XM, the default state of the LNA protection relay at the feed is the transmit state (in which the LNA input is isolated from the feed).
