Dual Dynon radios and PM1000 circuit diagram

[jaba-who]

I’m in the process of building a Jabiru 430 needing 4 place intercom to go with my dual dynon radios. Although I’d prefer all Dynon to go with all the other instruments I’ve got to go with a non-dynon dedicated 4 place - planning on a PM1000 II

anyone got a circuit diagram for a working set up with HDX, two dynon radios and a pm1000II?

As an intercom, the PM1000 only supports one radio out of the box. The PMA4000 has the same form factor, and supports two, but it's considerably more expensive. It gives you other capabilities as well, but all that may not be worth it to you. It is possible to use a PM1000 with two radios, but it will require somewhat significant custom work involving panel switches, a mixer (maybe two), and some creative wiring. That route may be preferable to you if you're really into that kind of stuff, but many aren't. I could help with wiring either way, but you have to decide which way to go, and what features you want. Personally, I'd spring for the PMA4000, and I'm a techno-geek. The cost of the mixer and the headaches of all the custom wiring would be worth the extra cost of the PMA4000 to me. But that's just me.
