When we moved our dish yesterday at the College of DuPage, there was no signal
on 990 MHz, but there was on 1130 MHz. We realized that the downconversion by
5150 MHZ means hat it should be on 1130, and sure enough, that’s where we found
it. It’s a “hotter” signal than the old NOAAport signal by over 3 Dbm…and more
stable. Now to get data flowing across it…

Greetings all,
The NWS has updated their NOAAPort/SBN Transition schedule. The new dates are
as follows:
=======================================
12 NOV 2022: G31 Launch Date
5 FEB 2023: Dual Illumination Period
17 FEB 2023: Receive Site Transition Window Start
31 MAR 2023: Receive Site Transition Window Ends
3 APR 2023: AWIPS Transition to G31 Complete
=======================================
The SCN also mentions a change to "the RF Frequency." However, since they took
down the previous SCN I don't recall what the frequencies were before, so I'm
not sure which one was changed or what the previous values were. Here are the
values listed in the current SCN:
Satellite (G31) specifications/AWIPS
-- RF Frequency: 1130 MHz
Satellite (G31) specifications/NWWS
-- RF Frequency: 990 MHz
For more information here is the full SCN that just came out with this
information:
