Hey Rodger,

Unfortunately, I don't have a document for building a Allstar with a radio.
The first article on my website covers a Allstar to DMR bridge and setting up a radioless Allstar hub. 

However, I bought a Yellow box from George WB3DZZ. He has taken those BF radios apart and made his connections to that and the sound cards his nodes also come with the HamVoip software. 
He may can give you some tips since you have most all the pieces. 

Otherwise, I would point you to the Allstar email list.  

I like the HamVoip software but you can run ASL as well on a Raspberry Pi.
here are the emails for both groups:

Hope that helps let me know if you have any questions.

Hello Russell

I was put onto you from a fellow ham here in New Zealand, that said you
had a very good document on how to put together an allstar node.

I have a Raspberry Pi 3, and couple of BF888s radios and two USB sound
cards, but not sure on the software to put onto the raspberry pi 3 and
how to connect it all.

Would you mind sharing you document if one should exist?

Have a Merry Christmas and happy New Year.
