lengriff, During a net discussion about some issues seemingly related only to the RPi versions, it was brought up that the RPi should have a heat sink on the CPU. While the RPi sips very little power, the CPU is still going to get warm to hot, depending on load, and should be heat sinked.... just like any other CPU. Why manufacturers don't included them, is more a question of expense and other business politics that we shall NOT get into on here. I just learned the RPi itself has a "Turbo Mode" and explained to me it is similar, but not quite, to over-clocking. In this case, a heat sink with a fan is a requirement unless you want to keep buying RPi's. Also, locally two nodes had to be reflashed after utility line voltage drops during storms, but line voltage comes back on quick enough, it never fully dropped to zero. The RPi's would be stuck in a state in which whatever it was doing, it will continue doing it, but nothing else could be started or stopped. No connections could be made, command executed, etc. I am sure there is a better way to explained, but even after proper RPi full power-cycless, the RPi node never recovered after the power 'blips'. There were some stories of commercial repeater controllers having the same issues with utility line voltage fluctuations. The repeater controllers would hang, and have to be physically power-cycled by a visiting the site. Benjamin, KB9LFZ On Sat, 2017-07-29 at 10:16 -0400, lengriff@optimum.net wrote:
At ETSNJ, we run 2 repeaters off a Raspberry Pi. After a few days, the audio begins to suffer brief interruptions with a clicking type sound. It progressively gets worse until it is chopping up the actual conversation. I can clear it by re-booting the Pi, but it returns after a time. I've looked at the running processes, and do not see anything abnormal that would chew up processor resources. Anyone have thoughts on what this might be? _______________________________________________ App_rpt-users mailing list App_rpt-users@lists.allstarlink.org http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_rpt-users
