4thehoarde Posted September 16, 2020 Share Posted September 16, 2020 An/arc-190. Had hf 1 and 2 coupler fault pop up mid flight. Would rx but no tx or tune tone. Repressurized #1 coupler and both started started working again. Didn't make sense to me why #2 would start working other than the rf interlock relays are the only thing that shares a connection (i believe). However, sys would work fine until the next day, and the same problem returns on both system. Repressurized #1 again and both starts working. Anyone seen due to hf 1 fail, to cauaes #2 to fail as well? Could this coupler be losing pressure over night? Dont have any parts so im trying to narrow it down Quote Link to comment Share on other sites More sharing options...
tinyclark Posted September 17, 2020 Share Posted September 17, 2020 Don't know why the #1 system pressure would affect #2. The worst thing the USAF did was put two 99.9% error free systems on the same bird. Woud have been so much better without the second system. The RF interlock system is ridiculously designed. I don't see that causing your problem. Wish I could be of more help. Quote Link to comment Share on other sites More sharing options...
