FS: VIC-1 / VIC-3 Intercom to Civvy Radio Adapter *Updated*
After making a bunch of cellphone only adapters that don't pass the PTT signal that a radio would need to operate I decided to build new adapter that does pass the PTT and allows you to connect ham radios in addition to cellphones to the VIC intercoms.
One of the audio paths is selectable between 300 and 600ohms which works for cellphones and I should work with most ham radios. The other audio path is 600ohms and is meant for ham radios only. But being just a guy on the internet can't promise which radios specifically will work or which won't. I don't have the time or radios to research or test even a fraction of what exists out there.
I originally prototyped something with a lot of fancy isolation electronics but it was just too expensive. In order to get the cost down I had to go back to basics and remove a bunch of that. The box still works well for it's intended purpose which is to level-match the audio signals between the devices.
Each channel has an audio level adjustment pot so you can drop the audio level into the radio/cellphone and prevent over-driving the mic input.
This board hides in plain sight by replacing the guts of a VIC-1 C2298 crew box and it allows you to connect two radios or one radio and one cellphone to your VIC system.
I will provide the C2298 box with my board in it, a pair of mating U229 audio connectors and wiring instructions. You will have to provide your own radio-side connectors and assemble the cable. You will also have to get your own cables to go between the C2298 box and VIC head unit (these are standard cables).
The C2298 boxes are all used and have chipped paint and scratches on them. They aren't NOS by any stretch, but they aren't bad either. Most are CARC coated but a couple are OD.
The cost is $150ea + $15 shipping.

So if I understand this correctly you’ll be making an adapter to hook into the Vic 1 & Vic 3 system that will allow for a ham radio to be connected to the radio input? Also wasn’t able to see pictures could you text them to me? 8315956642

I'm interested. I also can not see your images.

OK I think I fixed the pictures.
If enough people want these I will do a run. I have to purchase all the parts in bulk to get the price down to where it makes sense, so I need to make 20 of them in one shot.

And now that I can see the pictures it make more sense.

Re: New VIC-1 / VIC-3 Intercom to Civvy Radio Adapter Design
Would you be interested in selling just your board without the 229 connectors or C2298 box? Maybe just the connectors on the board like your previous versions have? I have been messing with the box I bought off you previously in an attempt to do just what you speak of. (Adding RX/TX)
I already have a custom box with all my 12v wiring in it and have left some of the 19 pin radio connectors to connect to my VIC-3, so I would rather not have another box or connectors that I don't plan to use.
I'm not good with circuitry, but connectors and soldering make sense to me. Figured it might cut out a lot of the cost if i didn't need all that hardware.

I am certainly interested in following this as well.

I know this is in the works but if I were able to provide you a VIC3 Lite crew box would you be able to do the same thing with that? Would love to see it in that form.

Would be interested in two VIC1 models.

Hi All,
I've got a bunch of boxes made. I'll start PMing people who have shown interest.
Thanks,
Augi

The boxes shipped today. Everyone should get them in a couple of days. There is a printout of the instructions in the package, but if you want them in color message me your email address and I'll send you a .pdf.

Got mine in the mail yesterday totally forgot it was on the way so it was a nice surprise. Could you send me a copy of the color print out if you’ve still got my email.
