Steve, I think you should design a new PCI card for app-rpt radio world. I use the 4 port PCI card my self. Works great. 

Have fun designing and bring your new product to the radio market.

Oh by the way my other nodes use DMK URI and they work just fine.

A link to the 4 port cards. I don't think they are for sale anymore.

Good luck and God's speed, (Because I want it tomorrow) David

 My understanding is that you can use *any* digium FXO/FXS (and possibly a less expensive clone) card it will work well and skrew the piece of crap USB interfaces.

I further understand/think that it *MUST* be a two port card with both FXO and FXS present is this true?

Or can you somehow get away with a single port FXO or FXS card?
Single port cards are cost comparative to a ready made DRI USB which is --->>>>>*NOT*<<<<<--- production remote repeater site quality/capable and good only for testing experimenting etc.

Even if such a card is TWICE the price of a DMK URI..  This is the way to go for a production system..

Which is *ALL* that I would ever run at a site..

And home I'll still maybe d*** around with USB interfaces which truly suck with app_rpt in ALL of my testing I've done in 3 years.

Am I clear in this understanding?
Any suggestions on cards/Interfaces that work well?
Any that don't?? stick with Digium?

I should have asked this bundle of questions 2 years ago *sigh*
I realize newer boards will not have PCI slots..  

"USB sucks + is unrealiable"
-->as I have been assured both through my own testing and the developers of app_rpt.
If you tell me you have a perfectly working sytem I'll have you do *my test* sit & listen locally at the system to the TX on continuously with PL encode and you *will* hear
the audio pops & interruptions in the trasnmitted audio that I am confident are present in ALL usb installed systems :-).. but has been proven liveable for most.
If you absolutely have to go with USB for whatever reason beagleboard etc.. small low power controller

then it's time for a different controller if you require production/site performance & reliability.

I thought i would get the server set up and then get the USB to radio interface.. what is the best and cheap one to buy.  I don't want to roll my own  as if everything works out well we will move the unit to the repeater site in the Spring. But for now 
 i was going to put it on a simplex node.   I just didn't want to buy the adapter then stuck with it with no way to configure the server..    for the time being i will hook it to the ft2600 yaesu ..
any thoughts on usb to radio interface?
