Pluto Ethernet problems
So, I’ve been running the Pluto over Ethernet to SDR Console on an old but still capable laptop just to see how it performs end to end. It clearly has issues! The first test was just pinging the Pluto from my Linux box with no SDR activity. This ran for almost 7 hours and dropped out in the early hours.
Then I tested it with SDR Console running to see if it would last as long. 10 minutes! Another similar test lasted about 1h45. I added ferrites to all the power leads and this time it lasted about 3h30. Nothing at all scientific in these tests and I had already read up on Ethernet issues and the need to strap ground connections together internally but wanted to just see if the ferrites made any difference.
Back to the workshop and I strapped the earth end of R58 to the earth end of D3 following the instructions found in this YouTube video at 7m36. The video describes that as the ‘simplified version’ - I’ve seen another more comprehensive one but this one is straightforward. There is a detailed investigation of the issue here and here. The Pluto held up running SDR Console looking at the lower beacon for 30 hours and is still running as I type this. I’ve not gone mad like running an electric drill next to the Pluto but so far, so good.
Edit: SRD Console has been running for 47 hours now with no issues. I only stopped it because I need to sort out the PSUs and coax entry for the QO100 transceiver box in the garage.
