  1. At least it didn't go across your chest!! Usually, you're OK if that doesn't happen.

    Yea, I hated working on that thing, but I like to think I raised the reliability rate on the RT289 in Europe quite a bit while I was there. I basically overhauled them when they came in. Tube checks, new PFN, TR tube, ATR tube, thyratron, magnetron, etc.

    They were always bitching about what we spent on our bench stock though.

  2. Tiny,

    Hey I see you're an AFET at Moody. I knew ACC had a lot of AFETs throughout the "lawn dart community" (fighters), I didn't realize there were any on 130s though. I guess you're mainly with special ops birds?

    I was an Avionics AFET on C-5s here at Dover from 1986 until I retired Jan 2007. Loved the job. Miss it actually. While we did travel overseas training and troubleshooting, we never had to deploy to combat areas like you guys. You really have my respect.

    We got sucked into the ACC program when that command took control of the C130s back in 1992, and then promptly gave them back to AMC as soon as they woke up and decided they may have to chew their arm off to get away from the old girl.

    We're the red-headed step children of the program. We are deployable, but haven't as of yet, since we don't send a full squadron as the fighters do. Not that I don't want your respect, but I can't take credit where it isn't due.

  3. APQ175 was X band and Ka band.

    The replacement for the APQ122 had to be form/fit/function. They had to put a lot of crap into that system that wasn't necessary, just to meet the "guidelines".

    Ku band is only 12-18 GHz.

    From the shop manual:

    Frequencies (SRGM) (nine selectable channels)

    32.2 GHz +/-50 MHz

    32.3 GHz +/-50 MHz

    32.4 GHz +/-50 MHz

    32.5 GHz +/-50 MHz

    32.6 GHz +/-50 MHz

    32.7 GHz +/-50 MHz

    32.8 GHz +/-50 MHz

    32.9 GHz +/-50 MHz

    33.0 GHz +/-50 MHz

    70.8 kW peak min at RT/antenna interface flange

  4. I have very little experiece with the A/C system, but is it possible you are losing some bleed air via the aux vent valve or the floor heat shutoff valve? What about the cargo compartment/flight deck diverter valve?

    Also, is the air recirculation fan on, and is it operating the way it should be?

    This is what was in Volume 16, No 2, Lockheed Service news:

    If flow is weak, or if there is no flow, check the position of the flow control valve. The position indicator on the side of the valve should indicate about one-third to one-half

    open. The valve operation is affected by ambient conditions and bleed air system pressure; therefore the exact position may vary somewhat, depending on operating conditions.

    Be sure to check for system leakage at duct joints, especially at the water separator. Visual inspection will usually pinpoint this type of trouble.

    A failed cooling turbine will also result in reduced airflow; however, this condition will also be accompanied by an inability of the system to provide adequate cooling.

  5. also there are what appears to be two cannon plugs to the right of the flare tubes that are on the exterior of the aircraft what are they used for?

    Is there a plug number on the inside of the aircraft for those two cannon plugs, or a wire number or two you can give me??

  6. I believe that was the one, are you sure it was a 37th crew? Hell, could have been a regular AWADS bird too, I've slept since then.

    They called me late that night and asked me if I was sure I red X'd it.

  7. Speaking of radome bolts...

    I opened the radome on Talon 1 at Rhein Main, and red x'd it of course. The aircraft took off and landed at another base, and they noticed the radome was loose.

    Turns out the guy that signed it off from the truck had a 3 level go make sure the bolts were installed in the radome. They sure were, well, at least the dummy bolts on the outside edge were. He never looked inside at all.
