Severe IMD but no OV indication
The Kiwi at KPH (http://kphsdr.com:8072/) fed by a Marconi T through a Nooelec broadcast band blocking filter. Nevertheless, there is severe IMD across the whole spectrum even though no signal is greater than -30 dB and the OV never lights up. There are no active components in the transmission chain ahead of the Kiwi so I'm at a loss as how to debug it.
