Check losses in big LPF

Not good at all — heater 🙂

Not the best, around 20dbc — 26db PEP average, needs some work 🙂

10watt power 28dbc — 34db PEP: 10watt power 30dbc — 36db PEP: 5watt power 15dbc — 21db PEP:

102W 26dbc = 32 db PEP (taking average — did multiple measures and they were around this value): 1A current on the

DAC driver output — intermodulations somewhere at the noise floor 🙂 : 50W 37dbc = 43db PEP: 80W 31dbc = 37db PEP:
