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!) ~Ken .-.-. -------- Forwarded Message -------- Subject: Getting Node 2134 back online / Raspberry Pi 2? Date: Fri, 22 May 2015 01:29:03 +1000 From: Ken Page <vk4akp@gmail.com> To: app_rpt-users@ohnosec.org 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. http://www.dorji.com/pro/modules/Audio_voice_transceiver.html - 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.
