After changing the power supply on my secondary ‘combo’ for the third time, and going through a couple of +35 degrees in the garage, I think it’s safe to say the so called “RPi Power Supply” from eBay cannot handle high temperatures. It still works fine indoors, in an air conditioned room. Those were the first 2 PSs.
Also noticed, and mentioned previously, performance improved a little with the new PS. That is an expected outcome I think, with a better quality PS.
I asked in the past about software updates increasing performance, as I had observed such a thing. The consensus at the time was that it was not likely. Well… it happened again.
I updated the software on the secondary ‘combo’ through PuTTY, not via the FA page, and after that it started decoding more planes than the primary. It’s been a couple of days now. The primary had been consistently 5-10% better in the past, but the secondary is now a few planes ahead.
The primary ‘combo’ is using the standard 3.7.1 FA image, no updates. The secondary had the standard 3.7.1 FA image, before issuing the sudo apt-get update and then upgrade commands.
