MPPA Modifications to get flat frequency response: --DB1CC (talk) 13:12, 31 May 2014 (MEST)

Please replace inductors L1,L2,L3,L4 with 0-Ohm resistors
and remove C17 completely. See the modification on the Silk screen here:

After modification, the frequency response will be typical flat
with a slight gain improvement around 50MHz to compensate for losses at 6m
