Some LNA tests for HRIT/LRIT

So I was talking with @luigi on OSP RocketChat and he noticed that one of the LNA’s I suggested alogn with the LNA4ALL (the SPF5189) got a comment on ebay saying that it doesn’t work on L Band.

So that was weird to me, since I have 5 of them, and one currently in use with my GOES setup. So I decided to do a small and crude benchmark for L Band comparing no LNA with LNA4ALL and SPF5189.

GOES 16 Test Week Results

In the week from March 27th to 31 NOAA performed some new downstream tests over HRIT link on GOES-16.

Some of them are automatically posted on Twitter / Instagram by my OSP Bot but not all of them. I had discovered some issues with my Virtual Channel Ingestor on GOES Dump, and also most of the new data was not being handled correctly by Goes Dump. Working together with @usa_satcom we managed to almost zero-out the bugs in GOES Dump.
