Thanks Doug,
I just got a Pi2 yesterday ;-) and picked up some micro SD cards today at Costco.

It should handle two simplesusb radio nodes. usbradio is still NOT recommended and may never be in its current form. See future notes below.

Make sure you understand the configuration parameters before changing them indiscriminately. If you are moving a radio from another Allstar simpleusb configured system the settings including audio levels would be the same on the RPi2. So make a note of them before you switch.

Values 1 to 24 are the number of 20ms frames of delay. Typical values are from 5-10. Listen on iaxrtp or another local node to hear your own squelch tail. It is the tail the node radio creates when you immediately unkey not when your radio squelches. Experiment and use the minimum value that consistently eliminates the squelch tail.

Software support for a switch is built-in to the distribution but it needs to be turned on in /usr/local/etc/allstar.env  Other methods of shutdown are sending a shutdown command using ssh or a HDMI monitor and keyboard or activating DTMF control in the rpt.conf functions section. When you halt the processor you will need to power cycle to restart. So this is generally not something you would want to do remotely. It is a good idea to always properly shutdown your system. Unless absolutely necessary don't just pull the power.

If will be multi-threaded with a separate manager thread to handle telemetry. This will allow interface to virtually any audio device that can be hooked to the board. We also feel that the current usbradio type commands will have a high likelihood of working on the RPi2 with the new code and it will also make GPIO interfacing for COS, PTT, etc. much easier. It also opens the door to use better DSP software packages using the floating point capability of the RPi2. Audio noise floor and quality could be even better than it is now. We are very excited about the possibilities. You should see test versions of these drivers in the next few months.

For that reason I would recommend that any future purchases for new servers be the RPi2 rather than the BBB. It is also likely we will see the BBB's availability go down and cost go up in the future as sales go down. It is hard to predict a time line on this so just be aware it could happen. That being said if your BBB board is working well and serving your needs there is no reason to replace it.

Also be sure to reload web pages and how-to's to make sure you have the current version. The RPi2 like the BBB is extremely easy to setup using the automated scripts. Just be sure to have all your information together before you start - node#, Node PW, IP address and gateway if static, etc.
