[hpsdr] ADC Overload

Hi Jeff, all

Oh, I have not thought of this full duplex mode also, since I am 
currently using the Mercury/Pennylane only in synch Frequency mode.

But I have looked into my current configuration: I am using the normal 
ALEX configuration, the output of Pennylane goes through a 50 
Watt-Amplifier to the "TX in", the Mercury Antenna plug is connected to 
the "Out to RX". The Antenna coupler is attached to the "Ant 1".

I assume, that ALEX does protect the RX when Pennylane is tx-ing. (Else 
my Mercury would be destroyed by the 50 W).

I don't control any ALEX settings, since these are switched by the 
FPGA-Code. So, why do I get sometimes "ADC overload" when tx-ing?

Any comments are welcome
