Yes, I get the same clicking sound in my Cherokee, but no interference in the Rans S6S or the Drifter. The funny thing is that if I touch the instrument panel above the intercom it goes away (until I move my hand).

This is with my Lightspeed headset, I haven't checked if I get the interference with the normal headsets.

 

Have you tried moving around the cockpit?😈

Hi Kiwi,

 

This sounds like the old days when trying to get a better signal on a black and white TV by asking somebody to hold the aerial in a different spot. You'd get a really good picture - but if the person then put the aerial down at that spot the picture turned to crap again "Hey mum - just keep standing there holding the aerial!" LOL

 

Cheers,

Neil

USB PD stands for Universal serial bus power delivery. It has nothing to do with Apple or iphones. It is a universal standard that delivers 5 amps at varying voltage inputs with a maximum out put of up to 240 watts. Many low input devices will not communicate with PD chargers including the SE2.

 

QC3 is indeed a Qualcomm proprietry product with less output at about 36 watts. QC 4 & QC 5 are much faster & can charge at astonishing speeds like charging a mobile or tablet from 0 to 50% in 5 minutes.

 

 

"Universal" in IT/Telecoms is a bit like "World Series" in baseball. Just because Apple and the USA call it doesn't make it so.  MM/DD has the same sort of universality. 😇

Just back from another fly -

• Found that Kiwis observations at correct.
• If I turn me head, can receive or block the clicks.
• Putting my hand up close to the SK2 also blocks the interference.
• Touching the instrument panel , not sure
• Turning off my noise cancelling has some effect but this could be background noise drowning the clicks.
•  I am going to try a foil shield next time round - I will try & place/ size it, so as not to block the SK2's function.

 

Seems odd that only you few respondents have come across this phenomena.😈

Started raining at home and had to stop mowing...

So sitting in the cherokee in the hangar with tablet on, SkyEcho on, no clicking.

 

Master and intercom on, clicking is there. 

 

Intercom off, no clicking.

 

Cheap headsets make no difference. 

 

Move the skyecho down the back of the plane, no clicking.

 

Definitely coming through the intercom.

The clicking will likely be the intercom. I have a Flightcom and it clicks. I have read on other forums that PS intercoms have better filters and are better quality product; no clicking.

I am running a Trigg transceiver/intercom, into David Clark, noise canceling, headset - annoying background clicking.

 

Othered than experimenting with location (limited options in my case) has anyone come up with a fix?

I suggest seeking professional help.    

 

However, if not available, you might want to try with RF Ferrite chokes. As mentioned, the troubleshooting takes time as wiring in every aircraft is different, and RF is "unpredictable". 

 

The ferrites can be of different material, sizes, hence effective on different frequencies. 

 

I would start from the headsets, wrap the cable that goes into the earcup and see if any better, then try at the intercom, put a ferrite around every cable/wire that goes in and out, including power, and see if that helps. Then try radio(s). 

 

The video below is one successful example, but I wouldn't call it "Easy way". 

 

Good luck !

Nice video and certainly something worth trying.

 

Small problem - The SK2 has no physical (wire) connection with any part .component in the aircraft😈

SE2 is a radio transmitter.

Any wire(s) in your aicraft can act as a receiving antenna.

The catch is to find which wire (or wires) are causing interference.

 

The video below is showing a demonstration of transmitting RF energy wirelessly.

 

ps: suggest talking to avionics guy.

I have ferrite chokes on all radio cables at the radio and headset jacks etc and my SE2 does not interfere with the radio at all no matter where I put it. The chokes there will filter out interference from other electronic devices and electro magnetic sources so if you don't have these it is a very cheap and effective solution. They only cost $12.95 for a pack of 2 from Jaycar and clamp around the cable next to the radio or headset socket etc. You may even find your radio performs better after installation as an added bonus.

What made you decide/invest in ferrite chokes in the first instance?

I ask because my transceiver delivers very clear communication in in & out. It's only the introduction of the SE2 that has resulted in this annoying clicking.😈

[kgwilson]

Aviation frequencies are VHF & very prone to interference & these were recommended by the radio manufacturer as well as a number of publications on radio installation. I also installed a power filter. The Microair radio I have does not have a good reputation & some of this is due to poor installation techniques. Mine works very well and pulls in transmissions from great distances. I also tuned the antenna to the main CTAF frequency.

[skippydiesel]

Kgwilson, 

 

"I also tuned the antenna to the main CTAF frequency."

 

I have almost nil understanding of electronics/radio frequencies etc however I do have a SWR meter, from memory the instructions, for antenna tuning, say to set the transceiver to the middle of the frequency band.

 

I guess the theory is that the antenna will have acceptable receive/transmit capacity over the whole range.

[kgwilson]

I set mine close to 126.7 as that is the most common CTAF frequency. It receives all other frequencies and of course area have much more powerful transmitters so no problem there

Have a link to a wavelength table.

https://www.cumulus-soaring.com/files/antenna_lengths.pdf

 

 121.5Mhz might be a better frequency as it is the emergency frequency and the 1/4 wave (24.3" 617mm) is only 1" (25.4mm) longer than 126.7 (23.31“ 592mm)
