PSA: check the coax connector torque before you blame the LRU
I was talking to a guy at the shop in Wichita last month who swore his radar fault was a bad antenna, and he swapped parts for two shifts straight. Turned out his connector was just hand tight, a quarter turn with the wrench cleared it and he felt like an idiot. How many of you have chased a ghost like that when the real problem was the connection all along?
