Well done Allan,

I bought one of the bluetooth units recommended by Brinsley, just to try it out.... then realised I don't have any bluetooth speakers or headphones, so bought a small speaker during our weekly Tesco shop but got home to find it isn't bluetooth - .....Bu**er! Guess I will need to take it back tomorrow.

I see your bluetooth unit is different from Brinsley's Allan, can you post a link so we can take a look please.

Regards

Peter

Thanks Brins,

Funnily enough it magically appeared in my Amazon homepage this morning under 'Related to items you've viewed'. Scary or what?   (- OK What )

There's quite a few Bluetooth devices out there, when looking I was making sure it had a good battery life and also using the latest protocols available.

Peter.... no Bluetooth headset 😂😂😂, love the shopping trip too 😬😬😬😬

I would certainly recommend the Bluetooth option to anyone that has Bluetooth headsets, less cables, no interference etc 😁😁 thanks Brinzlee on recommended this

I spent many hours checking things out to get to the bottom of this interference, everything was wired correctly, tried new power sockets, screened audio cable but to no avail didn't fix it so Bluetooth was the way to go...

I say it again Allan - definitely a good job well done!! 

Just thinking - our CFI uses Bose A20s in his flexwing (fitted into his existing helmet) via a fancy Lynx intercom. His students/ passengers still use Flycom helmets. I have just finished installing PAW for him and integrated the output from his PowerFLARM Core, but deliberately didn't connect up PAW audio yet to avoid potential conflict during instructing/trial flights. Looks like a perfect candidate for a bluetooth connection as he can then decide whether / when he wants PAW audio to his headset only.

Latest update, after some weeks waiting for my ground loop isolator, which by the way supposed to have been delivered from the UK within 2 days. 

Tested this on my aircraft today and it also fixed the problem.... what a result.

Also done some nice flying too 

So at the end of this, anyone with the same issue then you have two options

Ground loop isolator or a Bluetooth transmitter

Both will work fine

Hi Allan
Great news
Can you post a link to the ground loop isolator for others.
Thx

This is the one I got http://www.ebay.co.uk/itm/Mpow-Ground-Loop-Noise-Isolator-Car-Audio-System-Home-Stereo-With-3-5mm-Cable-UK-/152353458215?hash=item2378f94827:g:yEsAAOSwXSJXPVsY although delivery time was rather slow

Paul and Allan - My audio is usually perfect with no noise even with PAW installed in the C42. However, for the first time today I plugged an audio lead between PAW and my Bose A20. The video I recorded today illustrates the noise I am now getting on my headset. The minute the comms kicks in the Bose overrides the PAW audio and there is no noise or interference. Do you guys believe that the little device you have identified will get rid of this noise if I plug it into the audio connection between PAW and my Bose? Thanks....video is at https://youtu.be/OP0cq9J8Oew

Evening Roger

You've got exactly the same problem as I had, I also have a Bose A20 headset, with Bluetooth.

I can confirm using either a Bluetooth TX as shown in this thread or even the ground loop isolator, this will fix your problem. I spent many days trying to resolve this, thought it was a wiring issue, even spoke to the manufacturer for my radio.

I'm currently using the ground loop isolator for my PAW and then I use the Bluetooth side on my headset for my iPad, giving me warnings from SD and also making calls via my mobile 

Kind regards

Allan
