<div dir="ltr">I am running WSJT-X on a receiver a couple feet from the RPi, and I can see (and hear) the beautiful tone<br>from the radio and in the waterfall, but the tone stops after only a few seconds, despite the program thinking<br>that it is still transmitting.<br><br>I first tried it on my newest Pi 3 B+, and thought that maybe it was the faster processor confusing things,<br>but when I went to an older Pi 3 B, I got the same results. The duration of the tone is variable, sometimes<br>only a second or two, and sometimes as long as 10 or 15 seconds.
