Probably yesterday's data are not much good. This morning I figured out what went wrong, and reset it to correct values in time for the morning high-frequency receiver calibration. I am trying to determine the EQ coefficients and come up with a scheme for setting them quickly and automatically, and to allow them to vary with antenna and band.</ins></div></td></tr>
