Dynon Audio panel / Intercom with 2 radios

[PAN-Denmark]

Hi, relatively new to Dynon Skyview - just bought a RV7 with only 1 SL30 Garmin NAV/COM radio that currently doubles as intercom too.
First order of business for me is to add 1 extra radio (Dynon's 8.33) and I want to keep the SL30. The aircraft has 2 Dynon Skyview units (10" touch and 7" non-touch). For this to work I am thinking to add the Dynon audio panel too.
I have the following question:
The audio panel has input for 2 radios (and some other inputs too), but how do you switch between listen and transmitting on the radios ? In my current RV I just installed some 1 switch to select which radio to transmit on, and then 2 switches that enables me to listen to the radios (or not listen) - or is there another smart way ? Could it be controlled from the screens ??

Hope you can help

regards
Per, Denmark
RV6A and in a few days RV7.

Which audio panel are you planning to use?

The SV-INTERCOM-2S isn't technically an audio panel. It's an intercom. So there are limitations you have to live with. You have to install an external SPDT switch for PTT, page 2-8 of the install manual.

You can do the same thing for receive if you want. But that almost gets you to the point of getting an actual audio panel. The switches are far cheaper, but the install is more complicated.

As I suspected, you were thinking of an intercom, not an audio panel.

Like yours, my plane has two screens and originally had just one Dynon com and a simple 4 place intercom. When I added, among other things, a second com and 2 VHF nav radios, I had to replace the intercom with a true audio panel. On the advice of the folks in the Dynon booth @ Oshkosh, I chose the PS Engineering experimental model, the PDA 360EX. It does the job nicely and is a lot less expensive than their certified models. There's enough documentation that I found making all my own cables straight forward (not simple, but if you read and work carefully it is indeed do-able). It allows audio alerts from both Skyview and my IFR GPS. It will definitely solve your 'who is transmitting and receiving?' situation without involved switch-ology, and do a lot more. Worth your while to check it out if you decide an audio panel is the way you want to go.

Hi - thanks for the input - looked for the PS Engineering PDA360EX which is out of production and not to found anywhere... Then I came across their PAR200B which is an audiopanel and external radio, incidentally the same TRIG TY-91L radio as is inside the normal Dynon 8.33 radio. I am just wondering if I would be able to remote control the radio from the EFIS, like loading frequencies etc, as this is only $500 more than what I would expect from the Dynon solution I am very tempted... I will try to go for the books to see how Skyview interacts with radios.

The EFIS will only control one radio. You can see a second radio displayed, but you can't control it or transfer frequencies.
