[Elecraft] Sherwood's receiver performance table updated

[Jim Rodenkirch]

Don: requiring a wide ranging ATU is half of the question, Don!! What is
truly "significant" is this - many hams, new or otherwise, fail to
understand whether they really need an ATU in the shack or do they really,
REALLY need an ATU out at the antenna. For me, THAT's the mystifying piece
of the "ATU question" that always shows up.....
