Has anyone seen a L8743039-1 heat exchanger installed? It is the newer Heat Exchanger and was supplied to me unpainted, (It is stainless steel). The older 85027-1 Heat Exchanger is aluminum in construction and painted with Black Wrinkle (High Heat) paint. Just wondering if anyone has seen the stainless steel version installed, or knows of a paint spec or type for the L8743039-1 exchanger.

The drawing shows no requirement for paint. Why would you want to ruin a perfectly good piece of stainless steel?

I don't have your exact diagrams probably, but most of the XMIT audio is set up like on the attached, very crude, drawing.

That ground is the 115VAC common. no wonder it was causing issues. The largest connector on the antenna does contain all the signals needs for antenna stab. If the gyro seems to spin up now and everything works with that connector removed, then my guess is another bad antenna.

It's sure a good thing the USAF decided to get rid of the back shops, or you could just pull it and take it in for a bench check. That would be too damn simple.

99.9% sure it is a transmit audio line. If it were an antenna problem, you would be getting a tune tone every time you key it, since it couldn't tune properly. If the antenna cables were swapped on the coupler mount antenna coax relay, that would cause that small dummy load to heat up pretty quickly. Does it sound differently when transmitting on CW?

If it transmits, all interlock relays are working.

What particular aircraft is this, and old ABCCC? Tail number?

There is the KY bypass relay (maybe not on this bird), has it been checked?

Are there any HF #2 toggle swithes to use that HF2 position for another radio, like the VHF FM?

Any time I have a loss of transmit audio, here's what I do. Go to the IJB and disconnect all transmit audio (mic) lines coming from all the ICS boxes except for the pilot's, and op check it with only that mic line connected. If one of the mic lines is bad, you should be bale to find it with a DVM as well. Sounds to me like there is a shield short on one of them.

Please let me know what aircraft you are working on and maybe I can come up with a few more ideas. You can also e-mail me at Moody, under the name clark, tiny.

We couldn't really do too much avionics wise. Maybe have them dry out dessicant for the RADAR with a blow dryer. Or send them to sheet metal to have some 28VDC fuses cut out of aluminum.

On the F4s in Thailand, we'd have to check out Mode 4 by coding the box in the CNI bay, which was in the NLG area. We'd tell them they should speak into the CNI bay voice tube in front of the seat to let us know when the caution light went out. It was, of course, the urinal tube.

F4s again- Always told the newbies that if they were setiing in the ejection seat, if the seat started moving, they needed to get out fast because it was getting ready to fire.

After a few minutes, I'd reach down and hit the toggle switch to adjust the seat, then get the hell out of the way...

On the C141, there was a small door on the floor at the nav station. I'd send a guy down to the avionics bay where the toilet was to check on something. After they was down there, I'd open the door and grab their shoulder and scream. Usually, I got to hear a bang from their head hitting the cockpit floor board above them.

Tiny, hope all gets real well soon....no lifting! BTW are you VN Vet? if so get to the VA and apply for a disability due to prostrate cancer due to agent orange...should be an easy award.

Muff

No Muff, a few years too late for 'Nam.

Here's hoping everyone gets what they want, want what they get, and get more than they deserve.

Tiny,

Glad to hear that all went well with the procedure---the one part I didn't understand was 'Seattle'. Isn't that a long way from Valdosta?

John

Seattle is a long way from Valdosta. But, they only do open surgery in Valdosta. Mine was done using the daVinci robot.

This is the only way to go. I'm glad my brother-in-law is a doctor up here and knew a very good urologist who has done almost 200 of these procedures.

Thanks for all the positive thoughts & prayers!!

Well, I have to let everyone know that I am the proud father of a removed cancerous prostate. I had an elevated PSA, so that led to a biopsy, and then surgery yesterday. The surgery was done up here in Seattle by a well known urologist that performs the procedure with the Davinci robotic aid, using 5 small holes and a stereo lens camera.

He told me that everything went excellent, and I will make a full recovery. Play on guys, and have your PSA checked!!!

Check my usual sources, no luck from any of it.

Yuma, maybe?

Very simple efficiency report on Omar Bradley. Too bad they aren't this easy today.

Kinda odd, but the yellow one, which you probably want, doesn't have any USAF management data.

Damn it, I wish these pictures would come up here at work.

OKAY, home now and saw it. It was worth the wait.

There is also a plan to put dual rails on our HC-130Ps. $$$$ Cha Ching.

Yea, the flare launch tubes should pose no problem

I was only 8 and I remember it well. We were at Walker AFB at the time.

Tiny, thanks for the pdf.

Is that for the old capsule or the new capsule? I don't know if they changed the power supply system for the new capsule as it was still in development when I left in 89.

Dan

I don't know Dan, it's the only book I have, change 3 in Sep 2000. I never worked on the stuff myself.

If you are that interested...

Bob, the ABCCC book shows the capsule has 2 200 Amp TR units powered off of AC.

The iron lung outlets could power some hefty stuff though, with 4 gauge wire.

Soap would be corrosive. Maybe they found that out the hard way.

I have to agree with Bob, there is probably some text that refers to that figure, and the guy who did the artwork numbered the exits from left to right.

When I was at Pope (73-75), in the Radar Shop, I remember 7885 was a law unto itself because it was the AWADS test bed/initial aircraft. Anyone know the subsequent history on her?

You must have known Bill Blalock then. He was the AFETS civilian that was supposed to be the AWADS god. He would come over to Germany to teach AWADS and SKE classes while i was there from 77-81. I'm sure I spent many hours on that bird, removing and replacing AWADS parts, among other systems.

I took his position in 1992 after he retired, and he died shorly thereafter.

The iron lung is a negative pressure breathing machine that allows the patient to breath if they can't do it on their own. The positive pressure machine wasn't invented until the early 50's, and you know how long it takes for the military to catch up on technology. So, any wounded personnel could be put into the iron lung during transport to insure oxygen intake. That's my take.

That would be the same knuckleheads that put a picture of a headset into the -23 job guides, in case the comm/nav tech with the headset forgets what a headset looks like.

Or the same knuckleheads that require pulling circuit breakers, putting danger tags on them, red X-ing the aircraft, just to change an LRU.
