I meant to add:

- check your receiver for SNR [Es/No, Carrier-to-noise] unless it's at least 12 dB in clear conditions, I suggest disabling HVS-1 reception. Unfortunately that means no GOES or Himawari.

Instructions for disabling HVS-1 are on page 16 of the Novra guide:

http://www.eumetsat.int/website/wcm/idc/idcplg?IdcService=GET_FILE&dDocName=PDF_DMT_736617&RevisionSelectionMethod=LatestReleased&Rendition=Web

- check both TelliCast for [ideally] zero packet loss, missed and recovered. There are some systems where there is steady stream of missed and recovered packets, but with the same count for each. Temporarily disable HVS-1 and check again. BAS should have zero packet loss.

Cheers,
David
