[hpsdr] Boat Anchors..PreAmps

[Lester Veenstra]

Quite correct, can be anywhere before the A/D. At RF or at baseband.  I suspect that for most of our applications, manual (end user controlled) will suffice. But having the FPGA calculate the number of clips would be useful (until reset) for the user to access.

....t the AGC needs to be before the ADC........a software programmable variable attenuator to use this 
technique or fit an external one perhaps connected to the I2C bus?
