Last night I could not receive any  CH2-Ch47 HD channels .  Same channels in SD OK.  I keep getting 771 error, Sat 1 .  No problems with higher channels  . I checked cable connections , reboot receiver , re-powered  SWIM  etc  with no effect.  
However this morning everything is back to normal again ie I can receive Ch2-Ch 47 HD again
Any idea what happened ? Weather related ?
Tks
