Re: Re: [Paparazzi-de =?ISO-8859-1?Q?vel] Xbee an 2.4Ghz v?= ideo TX

Hi Simon,

the video signal is broad, loud and constantly sending. You would need
some very well tuned narrow filter to separate the XBee receive path
from that.

Another thing we tried was to turn off the video tx while receiving with
the XBee. There is a dedicated pin where the XBee tells you when it is
on. Problem here is that the video monitor takes some long time to
synchronize the vertical - hard to see anything.
