Sounds from skyview

[rfazio1951]

I have a SV1000, dual radios, an iPad and a phone connection all into an audio panel. Almost always after I take off and climbing out I hear a musical tone in my headset. I never knew where it was coming from. I’m using ForeFlight and do get voice from that, approaching a runway, for example. The other day I went up for a local flight with no iPad. I still got this musical tone. So now I know it’s not coming from the iPad. It’s got to be the Skyview. It’s a dum, dum, dum, in lowering notes three or for notes long. It’s a joke between me a my buddy, trying to figure it what it is. Anyone have any ideas? Is something in Skyvlew telling me I’m reaching an altitude or something?

I would strongly suspect the phone is giving you some type of alert - try a flight without it, or in airplane mode.

 

[rfazio1951]

Airguy,  thanks, but I’ve got the phone Bluetooth off and I’m still getting the tones. My friend and I are laughing about it now. Trying to figure where it’s coming from. I wish I could post the sounds, it would be a lot easier than trying to discribe it.

Might your audio panel be sending in a VOR Morse code identifier?

 

[rfazio1951]

Hmmm, the audio panel has two vor’s connected to it. A Garmin 430 and a Val 2000. I can get vor identifiers but they sound nothing like the tones I’m getting. It’s a musical kind of thing. Some kind of thing like “ Ok you are connected “ or something like that.

Try turning off each unit one at a time eg iPad, phone, nav 1, Nav 2 & then Dynon audio - you’ll work it out [ch128521]

 

[rfazio1951]

I’ve tried with both the iPad and phone off. It’s not a VOR sound. It’s kind of like when you plug a USB thingy into a PC and it plays that little melody.

Not by chance getting a few tones from the AOA, are you?

 

[Bomar]

Are you wearing a headset with Bluetooth capability ? I suspect this tone might be generated by your headset to inform you that it was unable to connect to a previously paired device ... or something like that.

Try swapping your fancy, electronic noise cancelling headset with a cheap passive headset. I bet the musical tone goes away !

I love a good mystery ... let us know what you find !

 

[rfazio1951]

     It’s not AOA, I’ve got that working well and know what that sounds like. A beeping that gets faster and faster, not musical at all.

      I don’t have Bluetooth headsets. Only Bluetooth is two adapters into the audio panel. One is for the iPad and one for the phone. The phone I can shut off at the audio panel. The iPad is into an aux input that you can’t switch off. But if I have no iPad in the cockpit it eliminates that, I think!

      What started this was when I flew the other day with no iPad and by myself. Phone input is normally off. I’m climbing out after takeoff and “music” again. What the heck!   Where is this coming from.

I'd say don't just shut off the phone, but disconnect the Bluetooth adapters themselves. And when you say "the iPad is into an aux input", do you mean the BT adapter which you use for your iPad is on the aux input?

Anyway, that's what I'd do...perhaps the system is seeing the BT adapters and indicating power-on/identification of them (and it doesn't matter if something is Bluetooth-connected to them or not).

That'd be my next step.

 

[rfazio1951]

Steve, 

      Ok that’s pretty easy to do. The phone Bluetooth is disabled at the audio panel. That shuts off any sounds from the phone Bluetooth adapter. The iPad I have to physically unplug, also easy. I’ll try it.

      I tend to doubt it,but you know how that goes. The iPad connects very fast. I usually get runway announments from foreflight as I’m taxiing out. I get this music climbing out, weird.

 

[Dynon]

For what it's worth, I can't think of a musical type sound that changes pitch that SkyView makes, so I don't think it's coming from SkyView.

 

[rfazio1951]

Thanks Dynon, I’m flying tonight and I’ll do some testing.

Richard,
I have had something similar happen recently, it sounded like very faint music & I just dismissed it as a 'bleed through' from a local radio station - maybe there is more to it ? I'll now be more aware of it & will report if i find anything.
