| Subject: | SL30 intercom function |
The SL30 has a voice activated intercom function. Can this intercom be used
in conjunction with an audio isolation amplifier as the system intercom? I
don't see any way of putting the output of the isolation amp into the
intercom. Is this doable, or is it more of a pain in the lower posterior
than it is worth.
Thanks for your thoughts and observations.
Roger

Don't know why not. Wire the ship's microphones as depicted
in figure 7 of the manual. Route Nav and Comm audio to the
isolation amplifier along with any other audio sources that
you want to add to the mix. The SL30 integral intercomm
with vox will continue to function as before except that
any other audio sources will be imposed on top of audio
normally heard only from the SL30

Lets see if I have this sorted out correctly. The mics are connected per
Fig 7 and, the Pin 13 & 14 outputs go into the Isolation amp, and the
headphones are then connected to the isolation amp output.
I will have to weigh my options for a separate intercom.
Do you know if the intercom input can be on (grounded) continuously, even
during txm?

You could use the AMX-2A mixer from MakerPlane:
http://makerplane.myshopify.com/collections/avionics/products/10-channel-audio-mixer-mono-amx-2a
This device has a special mode that connects directly to the SL-30 Comm,
thus providing a fail-safe interface. The mixer can fail and the Comm audio
will continue.
The mixer provides 10 inputs, four with variable level and is housed in a
DB-25 backshell.
Available as a pcb, kit or finished product.
Cheers, Vern

Bob, many thanks for explaining it in detail. With your suggestions in
mind, I picked up some parts I had laying around and put this together:
https://www.dropbox.com/sh/rylqm9cect5ndut/XyaFh-jLE2
I'll have to find someone with an SWR meter and cut it to the proper
length. Then we'll see if it actually does what it's supposed to do. But
it's solid, and removed in seconds.
Thanks,
Holger
