Hi,

Forwarding one of many old messages that never made it into the 
collective! :)
Please see below.

(have been wondering why no replies on the group to many messages past 
few years. Now realized had to re-register under our GMail email. LOL!)

Hi,
Our nodes been offline now for what must be years after a hardware failure.
We were running on our Gentoo server which at the time was a real effort
to set up and get working even with a lot of help.
Years later we're still struggling to even get our backups running on
the new hardware. (Recovering database etc etc).

With the release of the Raspberry Pi 2 we are wondering if this might be
a cheap way to get our node back up again by using a cheap separate
stand alone device.
To this end I have a few questions.

- Is the Raspberry Pi 2 powerful enough to do the job?
- If so how many URI dongles can it handle OK?
- Is there an easy install script available for Raspberry Pi?
- In the past we have had issues with PTT lockups causing 3x burnt out
radio's over time.
I see a different interface available now. (RB-USB-RIM)
http://www.repeater-builder.com/products/usb-rim.html
It looks to have a few better features like PTT lock protection. Is this
a good compatible device compared to our old DMK URI's we were running?
Any other feedback / comments?
- Does the RB-USB-RIM and the DMK-URI have the same pinouts on the DB25?
(Looks like No!?)
- Could the 8x GPIO pins be used as serial (TTL level RS232) ports for
things like CAT control etc?
- Could the RB-USB-RIM 's Cmedia Sound IC be uses as a packet radio
modem (Another project, Not for All_Star) using the AX25 Linux libraries?
- Has anyone seen the AU$15 DRA818V/U radio modules? Any comments on
these? We are looking at the possibility of using these.
They offer 1 Watt on 2mtrs or 70cm's (model dependent), Pre/De-emphasis
can be switched off + frequency agile via AT serial commands.

- Is there any Digital Voice support (Codec2 etc) available yet in All_Star?
- Lastly we would like to link two sites via a 5.8Ghz WiFi network link
for a UHF CB radio repeater. (One site RX the other TX).
I assume we can do this with a PI-2 each end and have one still run our
Ham node as a separate and isolated situation?

Appreciate any feedback on this.
