[Elecraft] Change in the P3 noise floor

[Bob - W6OPO]

Larry,

That is usually due to the antenna's bandwidth especially if an antenna
tuner is used.  Really wide spans will show how sharp the antenna is - in
other words its bandwidth.

Again if an antenna tuner is employed it will look pretty sharp/narrow
compared to no matching network.

73,
