Hopefully it will be one of the end connectors, same as fangzz problem, and they can simply cut it off and install another one. What happens is some people are a little too aggresive when cutting the insulation material on the coax and cut it too deeply. This causes a gap between the center conducto...

If you are still wanting to check for proper bonding, antenna to fuselage, or radio rack etc, you should be using a milli-0hm meter and not just an ohm meter as you indicated earlier. Don't forget to check the simple, obvious things as well, like making sure the contacts between the radio and rack a...

The coax could still be your problem. New doesn't always mean servicable. I would check for kinks or chaffing along it's entire length. Not clear on what you checked on the coax. Did you check the shielding from the rack to antenna or the center conductor? The shielding is there to capture the RF si...

I figured that would get a rise out of you. Yes, it is alot of work but appears to be coming along very nicely. The end result is all that matters, not how long is takes.

He used to have a link to his website but now that he is one of those 180 elitist, he doesn't post it here.

Sorry, (DRILLED) out holes.

Since this is a major repair and you are going to have an IA, you are going to have something in writing to show that the drokked out holes are acceptable as is. The trouble is I don't think you are going to find any such reference. I believe your best bet and cheapest would be to advertise your win...

Your problem did change though when you used a "known good" coax. I don't think I would trust your known good coax. The antenna you are going to try next seems reasonable. let us know what you find, corrosion etc. Here is a picture of the corroded ADF antenna cannon plug with part of the a...

did the radio shop leave the radio powered up and test it repeatedly over an extended period to duplicate your (in aircraft) failure? If not you cannot completely rely on their standard test as a complete one. I have seen some bench tests fail to find a problem before. If you are going to temp insta...

It never hurts to check the easy simple things first like removing the radio to check the connections on the back and reinstall making sure it is fully seated in the rack. check headset plugs and clean tips with scotchbright to ensure good conductivity. You would be amazed at how many similar proble...

I would drill them to the smaller size like you want then slide a thin steel putty knife between the skins and gently tap the handle with a hammer to seperate the remaining spot weld. I believe they were of pretty poor quality anyway. It should come apart pretty easily.

If static electricity were an issue I don't believe the problem would be unique to your 170. I would be inclined to think the problem is more along the lines of a heat build-up issue either with your radio or possibly wiring issues. Do you have a circuit breaker supplying power to your radio or is i...

was everyone typing at once or what? I see george beat me to the punch.

An properly functioning engine of any horsepower rating is capable of hitting a tree at the end of the runway. It isn't a lack of horsepower that is the cause, it is a lack of planning.

Item 22 is the compression spring.
