Let there be sound
Hours: 3.9 | Posted in ElectricalFinished pulling the phone and mic lines through the airframe, and soldered them to the corresponding jacks. Terminated the transponder and #2 comm antenna coax and installed the antennas, at least temporarily (they’ll eventually have a bead of sealer underneath). I may end up putting doublers in for the comm antennas, as the skin flexes a fair bit with left/right motion of the antenna.
The audio system essentially complete, I had an urge to test if the jacks were wired correctly. Slid the audio panel and intercom into their trays, hooked up the two test leads from the VP kit to the master buss feed (one at a time, first) and flipped the switch…lit right up, beautiful. Once I had both running together (I knew there must be a reason VP provides two test leads!), I fetched my headset and plugged in. Works like a charm; audio is there, the PTT’s on the stick and the canopy deck work. I had to look up how to adjust the sidetone volume on the SL-40, as it comes set quite loud. Tested the copilot side too, also works. I think I have an old headset knocking around in some random box, I’ll have to pull it out and test it so we can both plug in at once…better than standing around talking to myself on the intercom! I couldn’t remember the AWOS freq for any of the local airports, though I doubt it would have come in anyway (nearest field is ~15 miles away). No music input handy to check that with, so that’ll come later this weekend. No noise heard from the panel or cabin lights, either.
