====== RF service ======
Yesterday Jim and I removed the mylar window over the feed. We inspected for moisture and found none. We also performed the following operations:

  * Sealed the S-band loop couplers with Araldite
  * tightened a few loose SMA connectors in the downconverter box.
  * checked the Elevation encoder mounting bracket bolts were tight that fasten it to the turning head.
