Confused by the discussin of Ku band receivers this morning I tried to learn what worked. Four antennas still lack a Ku band receiver: ea03, ea08, ea15 and ea28. ea09 is in the barn and is expected to have a Ku band receiver when it returns to service. ea22 RCP provides weak fringes and has a high T_sys. ea06 LCP provides too little power to the T304s.
