Mine too looks like the exhaust might block some of the signal, but it has worked fine all the time. Mine is quite far forward before the pipes get very far down along the sides of the antenna. I have the big Forsling exhaust that is about 3" in diameter at the end.

Is there another way they test? We have not narrowed it to a specific geographic location, it seems to happen at random. Our suspicion is that the antenna is being shadowed by the exhaust pipes. We were going to move the antenna back a foot or so, but wanted to get some feedback before making an assumption that that is the real problem. If others have it in the same location and are not having the problem then we would need to dig deeper. We did verify the cables and connections were good. -------- Jason Kreidler 4 Partner Build - Sheboygan Falls, WI Tony Kolar, Kyle Hokel, Wayne Elser, Jason Kreidler N44YH - Flying - #40617 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=297869#297869 ________________________________ Message 2 _____________________________________ Time: 11:14:48 AM PST US Subject: RV10-List: Re: Speaker in overhead console From: "AirMike" I used the right back seat armrest area.

I have 278 TT on my RV10 and have replaced 3 EGT probes from GRT. Failures have been on 6 then 4 (or 2) then 1. #2 failed this morning. Some are the original GRT EIS probes and some are their allegedly long life probes. I lost the third one on a trip to IL and GRT FEDEXed two "long life" probes to IL. I changed #1 and kept the spare. This morning on a local training flight, #2 failed (again?). Probes are located 2 inches below the exhaust port (specs call 2-6"). EGTs normally see high 1300 /low 1400 in cruise. takeoff and climb EGTs are 1200-1350. At altitude the LOP operation usually provided CHTs (275-325) and EGTs (1360-1410). GEM probes on a previous aircraft (TC177RG) were rated for 1650 F red line and since my normal operation was about EGTs at 1400. I replaced two probes in 29 years of ownership and 2500 hours.

Symptoms were intermittent extremes (zero to top of scale) while the engine was running/hot. Could not replicate the fault on the ground with the engine at ambient (though the temp from the d odgy probe differed from the others by a few degs) - it really looked like an intermittent connection due to engine vibe. Replaced the probe and it w orked like a charm (after much investigation into the connectors).

Other failures have been erratic. For example a 900 reading followed a second later by a 1300 reading. When removed, that probe had the outer cover burnt off and the welded leads to a small thermocouple were showing . One lead was detached from the thermocouple and was intermittently touching. the exhaust gases passing by would have caused the intermittent readings. will send picture of failed lead from another computer if I find it. ----- Original Message ----- From: Marcus Cooper To: rv10-list@matronics.com Sent: Sunday, May 16, 2010 3:56 PM Subject: RE: RV10-List: EGT probes It's probably been covered, but what where your indications of a probe failure?

Mark it to length, cut it, then split it if needed and bevel the inside so it mates up nice. Rough the inside up with 36 grit REAL good including a 1" forward area for taping. Mix up some stiff flox, butter up the joint and clamp it straight with light spring clamps. Filet the inside with a little flox, paint the sanded area with pure epoxy and apply 2 layers of 1.5 - 2" BID fiberglass tape cut on the diagonal and wet them out. Trim and finish when cured.

It's kind of like the sanding/filing down of the wing skin where they overlap at the spar. Some have to have that seam perfectly flush while some just rivet it on as it comes from Van's.
