He compared this with the set of 11 antennas with the highest efficiency at 1.3cm, compiled by D. Wood. The two sets have 8 antennas in common. M. Kestevan thinks the holography should be repeated at 1.3cm. Choice of standard frequencies at L Band. D. Bagri has measured apparent system temperature versus frequency over the front end bands.
Old receivers have a slope to greater sensitivity at the low end of the band.
He notes that the cals on many antennas are set slightly too high, and that a small improvement in sensitivity could be achieved fairly painlessly by adjusting them downward. B. Brundage showed the latest interference plot, and pointed out the lines at 1465 and 1486, which always show up. He suggests that these may be images of Forrest Service communications links at 1735 and 1714 MHz. Old information suggests that these frequencies are used in links to South Baldy. It was concluded that a single set of standard bands does not suffice, because of the interference problems.
