Issues From original WsprryPi code:
|
|
|
|
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.
|
|
|
|
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.
