  1. I remember we had a hydromite at Moody and Ramstein, but don't remember periodic draining. There's nothing in the old 130A-06 that says anything about it. Of course, I was the avionics guy.
  2. Looking at the picture and the question, the one that fits and doesn't leak. Why not use the IPB?
  3. Been there, done that way too many times.
  4. I know this is old and you may not see it, but yes. I started wrapping F4 tape around my scribe, should have worn a leather glove to hold the scope.
  5. Anderson pretty much covered everything. Therer are still ARN6 ADF systems on some H models as far as I know, but I've been retired for 10 years. I probably repaired close to a thousand RT-289s in my career. Early on after training on them, I started replacing the TR and ATR tubes on every one, as well as the PFN if it looked the slightest bit swelled. Our MTBF went up quite a bit.
  6. Is there a two way bubble level indicator on the antenna? Our APS-133 had one. Insure that the antenna is level on the ground with stab on and off.
  7. You can't TDR antenna lines for this system because of the reciever sensitivity of the RT unit. It is over -140db if memory serves correctly. You can rebuild the connectors, build new cables or swap with another aircraft to see if it fixes the problem. A majority of these kinds of problems are the cables/connectors. Not sure where your R/T is located, or how long the cables are. I built a set of cables just for troubleshooting for several of the different platforms I worked. Also, are there any in line connectors in your aircraft? Do you guys still have NATEC civilians? Tiny
  8. I have no idea without a callout in the IPB.
  9. There are way too many LAC processes to remember that much. Also, some wiring was replaced by newer designs. The 1-!A-14 has the story on aircraft wiring.
  10. You will have to contact Lockheed. I used to have access to those LAC processes when I was working.
  11. Not a pneumatics guy, but it looks like an expansion joint like the type used in plumbing. Doesn't the parts index indentify it?
  12. Try swapping the TCAS processor with another aircraft. It is always goo to know you have a working unit, same with the antenna, swap with a good aircraft.
  13. I would think anyenna or one of the cables. Are you sure all cables are connected properly?
  14. Munir, since it makes no difference which phase is monitored, any phase could be used. I have no idea why they chose phase C. Maybe the relay was closer to a phase C connection. The only person that probably knows is the engineer who designed it back in the 1950's. Sometimes, I think you think too much about these details. 😅
  15. Again, I have never heard of a DCU. What system is it?
  16. I have never heard of anything called that, Munir.
  17. There are 9 of them. all #3 in the pic. Location: OW sta 185 and 293, and Ail Sta 103.5 on the wings, FUS STA 671, 701, 731.

  19. Munir, For valve #40P107? Cage code is 82829 Contact Allen Aircraft Products, phone # 330-296-9621
  20. 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.
  21. Make sure the antenna cables are connected correctly. There is a possibility that two are swapped.
