Add the 20 EK1LZ spots to all the others and it becomes a big problem. 20
bad calls each spotted 20 times is 400 bad spots. When you look at the
problem collectively, it becomes more apparent as to the impact.
If the 20 EK1LZ spots were the only errors, that would not be so bad - I
guess... but that's not the case.
