RF433 приемник выдает последовательность байт хотя я ничего не передаю, возможно какие то беспроводные передатчики соседей засоряют эфир, но как узнать что это?

Example for receiving
http://code.google.com/p/rc-switch/
If you want to visualize a telegram copy the raw data and
paste it into http://test.sui.li/oszi/
Need help? http://forum.ardumote.com
Edited by hack.lenotta to force it receive to ‘everything’
and included all the files at once.
