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
