is it possible

[ffemt6488]

i have several ge orions, im wanting to link two of them tougether and make a vhf repeater

Anything is possible with enough caffeine, duct tape and super glue.

But really, I don't see why not. the DB37 port has a plethora of signalling pins by default, should be able to cross them over to make a basic repeater. In fact, you can cheat and just use the Pyramid SVR-200 repeaters and have them do the work for you. Their schematics would be a great place to start for pins and signalling.

I rock a SVR on my 800 edacs orion and M7300. Works great for TX and RX

All the pinouts are on the SVR website

I have built a portable "tac stack" multi band interop repeater using orions but just remember there is a lot more to making a repeater than hooking up COR to PTT. In standard repeater service you will need an external repeater controller, duplexer and an external PA. It is typically cheaper (when you account for all those things) to purchase a purpose built repeater.

im building the repeater for a local public works dept , it will have a duplexer and a seperate controller just having a hard time finding imfo as far as pinouts

 

[DisasterGuy]

Do you have extended option cables for the orions?

 

[DisasterGuy]

Everything you need to do what you propose is included in the attachment here. Just remember that the Orion has a 80/20 duty cycle. I would recommend that you pull the PA on the Orion back to low power and use a 100% duty cycle external PA to achieve whatever TPO/ERP you are licensed for.

The reality really is (IMHO) that while the Orion's are pretty solid radios they are out of factory support and by the time you purchase an external duplexer, 100% duty PA and controller you could pretty much just purchase a Hyterra / Momentum 1RU repeater with internal duplexer.

At this point I agree buy newer I found a set that has 100 watt repeater with built in duplexer,6 walkies, and 150ft of coax for 1500. But im just setting them up for a local public works dpt . They dont even have a fcc licence yet im still waiting to see what freqs there going to have befor I get to much more in depth.

Shouldn't be hard to do if you really want to use Orions. I'm using a Orion as a RX unit in a one-way x-band repeater setup. However the other radio isn't an Orion.

You will need to mess with the Programable I/O in ProGrammer. All needed connections are on the DB37 like Adam stated.

I have been wanting to do this same project, but with no suitable duplexer for a .600 split in my possession I haven't got very far with it.

It really is pretty easy. We had the old Motorola machine for our RACES repeater take its final breath a while back and used an Orion and M7100 exactly as discussed here until the Mastr III went in.

 

[ffemt6488]

i accuired a CDM750 moto im in the prosses of getting another to hook up back to back im thinking thats going to be the easiest way and connect them with a RICK controller and a duplexer

 

[DisasterGuy]

You will have the same issue with a CDM as the Orion related to sensitivity, selectivity and duty cycle. Also the RICK isn't a real controller so you still lack the ability to deal with management and legal issues such as regulatory ID. You can theoretically do the same thing with the Orion by just connecting the AUX out (COR) of the receiver to the AUX in (PTT)

im waiting on them to get me the radios so i can attempt it
