Issues

These are from the original distro and I am not sure they are still valid.

  1. Two users were reporting that the program never stops transmitting, even when intervals for disabled tx are programmed. The problem was in both cases fixed by flashing a new image on the SD card with a freshly downloaded image: 2013-02-09-wheezy-raspbian.zip. No apt-get upgrade or firmware upgrade was performed. After this WsprryPi TX was running successfully.

  2. One user reported his RPi died while in WsprryPi service caused by excessive RF voltage (90V) on GPIO4 created by a 100 watts AM transmitter 50ft away from the antenna. After the damage exessive current was consumed by RPi (1.1A from 5V supply), caused by short-circuiting in the 3.3V logic of the BCM2835 SOC. On his replacement RPi, he is planning to add galvanic isolation and buffering.

  3. If running from the console, recent versions of Jessie cause WsprryPi to crash when the console screen blanks. The symptom is that WsppryPi works for several transmissions and then crashes. The fix is to add "consoleblank=0" to /boot/cmdline.txt. JamesP6000/WsprryPi#10

  4. Documentation says wspr [options] --test-tone f but it shoudl be more clear that f is a frequency: wspr --test-tone 780e3
