Tonight I made some good progress on the small circuit box that will feed my homemade annunciator panel with the appropriate signals. I sourced a small Radio Shack PC board and a plastic project box, then scrounged up some 4-40 screws, threaded standoffs, washers grommets, and a pair of 15-pin D-sub connectors. I drilled and filed the large hole for the connector, drilled holes for the wires to pass through one end of the box, and drilled holes for the PC board mounting studs. Tomorrow, I'll start assembling the components to the PC board and wiring them to the connector. [Superseded.]
Next, I located a good spot on the right landing gear attachment cover for a small, transponder-type antenna. This antenna will actually be for the Monroy ATD-300 traffic watch unit. Its installation manual specifies that the antenna is best located on the belly, forward of the wing. On a QB RV-8, this is a tall order, since there is no access to the inside of the skin anywhere forward of the spar. The two places I would have liked to install it would be very difficult to accomplish. So I went with the obvious and easy spot. With about 6" of service length built into the RG-58 coax, the cover will be easily removable when it comes time for checking the gear bolt torques. [Superseded.]
