mmarien, I have the skyview piped into an audio panel, PS Engineering PMA5000EX. it works perfect, super clear audio from the skyview. I think what is happening to you is your picking up noise on the audio in to your PM1200. The muting is normal because it mutes the audio in when the radio hears something. I don't think it's a problem with your skyview or PM1200. Is the PM1200 an audio panel? or a radio? You've got to locate the source of the noise. Try it with everything off and just the skyview and PM1200 on. If the noise is gone you can track down the source that way. It could be as simple as a bad ground on one piece of equipment.
question about the sv with my radio filser ATR 600; no intercom or audio panel available, using actual intercom build in the radio, manual from filser says intercom is on ptt input 100mV; SV manual give output 10V max, may I use this input in the radio, no auxiliary input available?

Hello Support
''Connecting the grounds together isn't strictly required if the SL30 and SkyView display are grounded to the same place''
--------------------
Ok you got me confuse a litle..bare with me if you don't mind..
Do or don't I need to connect the serial ground ( PIN 3 ) of the SL-30 or ground it anywhere else for the radio to work first with Skyview...or just leave it unconnected??
Right now I have PIN 1 & 2 ( Power & Ground ) of the SL-30 connected with the Skyview harness on Serial Port 3 and Skyview is seeing the radio??
I have Pin 13 & Pin 31 ( Skyview Audio Output Left & Right ) of Skyview installed as part of my initial installation but they are not going anywhere so far...Where do I connect these two wires ??
I bought an Audio Mixer ( AP-60 ) as per Jake's suggestion ( http://www.fdatasystems.com/Products/AP-60/AP-60.html ) above so can I bring these Skyview audio wires to the mixer and then be able to hear alerts and warnings?
I've done all the connections of my Skyview fairly easily but with this I just don't know where to start or end to get it to work..
Sorry to be a pain in the .....
Thanks a lot for your time

I'll chime in here if you don't mind--
What I do is connect all the audio grounds and power grounds, where possible, to one spot which is usually the 'forrest' of tabs bought from B&C.
Serial (shielded wire) audio should generally only be grounded at the Audo Mixer, Intercom or Audio Panel (whichever is fitted) end not the radio end.
SL30 power & ground should go to power bus & ground bus respectively. Pins 3,4 & 5 are the serial wires that go to the SV Port of your choosing.
Audio Mixer - You can combine (join into 1 wire) the L & R audio from the SV & that wire goes to the 'mixer'.
You can pm me and I'll take you through the rest if you want, might give you a call to speed this up

Hi Jake
Thanks for the feedback, greatly appreciated
By reading your explanation, I'm starting to understand a little better where these wires should go...except this one...

Which one are we talking about here??
Thank you very much

Got my explanation twisted - it should have read as " Shielded, 2 or 3 core as the case may be, audio wire should generally only be grounded at the Audio Mixer end"
An example of this can be found here on page 10 http://www.ps-engineering.com/docs/PM3000_IM.pdf

Hi Jake
Thanks for the call yesterday,it was greatly appreciated.
I think that I will probably installed a separate intercom after all and bypass the SL-30 built-in intercom for ease of installation.
A friend did just that and had no problem whatsoever..
More to follow.
Thanks again

I also have a PS 1200. Hooking Sky view to the music input does exactly what was described earlier--hum/buzz that builds after quiet. I tried Y-ing music from my mp3 player and that overpowered Sky view but the buzz is gone. Either way, it just doesn't work well enough.
The mixer idea would seem to be the solution (I think the AP-60 is mentioned herein with someone having one about to be installed). I would love to hear the results of this if/when this combo is put to the test.
Audio isn't a huge deal for me, but later when the ADS-B stuff is worked out, I would like to hear traffic alerts. For now the only alerts that apply to my craft and flying are engine alerts and the big red flashing light on the panel might get my attention (thank you for the EMS warning light, Dynon). My plane is mostly for aerobatics and in the heat of battle an idiot light is great. Audio would add to that if I had no hum....
Thanks for the forum and any reviews on the PS 1200 and AP-60.

Thanks for the comments. I'm pretty much convinced that the PM1200 is at fault here. I have my panel out again for other reasons but am going to try connecting SV and GPS495 directly to my iCOM A210 audio pins to see what that accomplishes. Page 26 of the iCOM manual discusses settings for AUX IN.

It is odd because the music player has no hum but the SV does. The 1200 and SV don't play well together at all.
My plane is a two place tandem, day VFR, aerobatic plane. No need for an audio panel and no room in the cockpit for one anyway. I'm sure your iCOM A210 will provide your solution, mmarien, and I wish you the best of luck getting the feature to work correctly.

Same here. I have an MP3 player that I connect but don't always use it. I think while there is sound the hum is suppressed. The MP3 player provides continuous sound. Skyview and the GPS495 don't.
If the hum get too annoying I just blow in the mic and the hum quits for a moment, but then starts building again. :-/
Is the hum there with the SV connected and the music playing? I didn't try that. I know with the GPS495 connected and music playing there is no hum.

All,
When connecting the audio outputs from the Skyview, does one immediately connect the three wires (13, 30, 31) to a shielded 2-wire or 3-wire set to then reach the audio panel? The brown,black and grey wires reach my audio panel fine, but is there actually better shielding using shielded wires even though the Dynon wires are exposed coming off the back of the 37-pin connector?
Any suggestions to maximize the shielding?
Thanks
Russ

I forgot to ask this one as well:
With two Skyview screens, do I need to connect both to the audio panel (mine's a Garmin GMA240), or is one sufficient?
Thanks

Yes, you should connect both. The installation guide is slightly incorrect on this point. It specifies that you should connect both for redundancy, but in reality only one display is ever transmitting at a time (you don't know which one at any given time, but you don't need to either. It can change from boot to boot. It has to do with how the displays and the SkyView Network modules work together behind the scenes). By hooking both displays up in parallel, you ensure that you'll always hear audio. If you only hook one display up to audio, when that display isn't the one that's in "control" of the system, you won't hear any audio.

Good news.
I connected my Garmin GPS495 audio (brown wire) to iCOM 210 audio one (pin D in diagram above) and connected Skyview audio D37 pin 13 and 31 together to iCOM A210 audio 2 (pin C). Great sound and no background noise. I didn't use shielded wires as shown in the iCOM docs. I just used the harness from SV and the bare wire harness for the GPS495. I have the iCOM AUX IN set to ON and AUX LEVEL set to AF GAIN so the volume is managed by the volume knob and the separate devices.
I have some noise from the PM1200 but I connected the power for my headsets (lemo plug) and ZAON to the same pin as the PM1200 on VP-X so I think the noise is coming from there. I can definitely hear the ZAON fan through the PM1200. When I shut the PM1200 off the noise goes away. I think I'll try putting the ZAON and LEMO power on a different power pin on the VP-X.

Update - I moved the ZAON power wire to a separate pin on VP-X. I left the LEMO power on the same VP-X pin as the PM1200. I have a little background noise (hiss) but very little from the iCOM A210. I have more background noise when I turn on the PM1200 but also very little. Turning off Skyview doesn't change the background noise level. There is no change at all. Turning off the GPS495 also doesn't change the background noise. I'm pretty happy with that. They were the source of the background noise when I had them connected to the PM1200. The noise was intolerable. This is the quietest my system has ever been. Gonna fly next week when the spring rains quit and listen to what my Skyview tells me. Just you watch me.

I have audio output from my Garmin 496, Skyview and Flightline 760 com radio all hooked into my PM1000 intercoms non muted input though a 390 ohm 1/4 resistor in series connected from each output to the same common input of PM1000 and audio from all works fine. You can match the levels of the 496 and Skyview by setting their output levels in their menus.
