[App_rpt-users] URI Hook up for Yeasu VXR-7000 (Angeo and Kevin)

[Eric EG. Guth]

Thanks, Keven.  We have a two meter VXR7000 in Safed that we want to put on to Allstar.  We will follow your instructions.  Do you think that USBradio will work find with Raspberry Pi3 on this system? 

73,

So here we are...   back from the site.

There's a DB25 male connector that plugs into the Vertex VXR-7000. And, there's a DB25 male on the other end that plugs into the URI.

On the repeater end I have the following:
Pin 1 = shield = GND
Pin 6 = white = DISC OUT
Pin 12 = orange = EXT PTT
Pin 13 = black = GND
Pin 24 = red = TXD LOW

On the URI end I have the following:
Pin 1 = orange = PTT
Pin 13 = shield = GND
Pin 19 = black = GND
Pin 21 = white = MIC_AC
Pin 23 = red = RIGHT_OUT

That's it - no surprises.  Program the repeater correctly, and turn on "Remote" by pressing the switch on the front panel of the VXR.
Use the files at     www.masterscommunications.com/temp/2302/    as a 
guide for your ASL configurations.
The files shown are for DIAL.

I used the right output for voice - you don't have to,  just use pin 22 on the URI instead of pin 23 and change the configuration in usbradio.conf to:
txmixa=voice
txmixb=no

For transmitter audio, I chose TXD_LOW instead of TX AF IN because it sounded better.  This input is before hardware pre-emphasis and limiting so both are applied to audio that's inputted here.  That's why the usbradio config file does not have preemphasis or limiting turned on.

The high and low pass filter references in my usbradio.conf file refers to code that's currently in beta testing for DIAL.  That code will eventually be included in the DIAL release.  It's been available in XIPAR for years.
Steve Zingman may choose to comment more on its availability for those wanting to try it, and I can explain what it does if someone is interested.

Hope this helps...  Comments or questions welcomed, Kevin - W3KKC
