Only the Red led is on  if I see the error  No Amplifier connected
Green and Yellow are off

now the amp is turning on by him self ?  and I see blinking the  4 Yellow led  and also the Green led is now on and also the Red
its very strange but the amp is turning off and on by him self

No this is not normal, it is telling you that your power supply is faulty or underpowered.
Try a different power supply that can supply 5 to 5.3V at a minimum of 2A.

Thanks Ben  
Only I do not have a extra power supply for this moment
for now I have it into the USB from the computer .. and I know this will not by a good idea,,  but its for this moment working  4.9V
I do have a power supply for the iphone but I think this will by also not a good idea
I will look tomorrow for a power supply

maybe this is also the problem with the Amplifier  to low power  and the Amplifier turns off ??
for this moment I run the board with 2 Amplifiers  2x ferrite antennas  now I hope all will by work ok again
thanks for this info

greetings  Gert
