Paul, interesting what you say. When I started using the device in November, I started tidying up the table so that there were no wires crossing each other. There should be no ground loop, and at the same time I knocked down a 2-meter 5/4" iron pipe as grounding, which I introduced and which is connected to the device at one point at the antenna output.
Then I put several ferrite rings in different places, and there is also a filter on the power supply input, which was made on FT140-43 by winding the input wire bifilarly. So I rule it out, although I've never checked with tinySA for this kind of confusion.
I was thinking of emptying the cache from time to time, but I don't know how to make this automatic. Could this be the reason for the message at all? I tried to start with gdb, but the error comes from jtdx. Therefore, I do not know how it could be examined in this way.
