<P>In a further discussion with the Band 7 cartridge group at IRAM it has been agreed that they will investigate to what extent the Band 7 upper frequency limit can be extended with guaranteed specs and at no extra costs.</P>
<P>Spec items that have been identified to detoriate above 370 GHz are Rx noise temperature and image rejection ratio. The possibility of other specs detoriating above 370 GHz will be investigated.</P>
<P>For the noise temperature a reduced noise spec of 300 K between 370 and 373 Ghz has been tentatively proposed by IRAM.</P>
<P>IRAM will do this further investigation in June '04, after their PDR.</P>
