The LNB (antenna) on the C-Band satellite dish has a problem when it gets cold. Its not the crystal, I removed that when I did the GPSDO modification.
There is something else going on.... The quick fix (like, tonight its forecast to be 30F) is just to use a telescope anti-dew heater band wrapped around the LNB.
I put a PID temperature controller on it. Less than 1F swing at the moment.
Lets see how how the #ACARS and #ADSC message rate goes overnight shall we.
Even if you are a regular user of the @ADSBexchange globes map, this might be a new tip.
You can filter to only show just a specific data source.
In this case we are filtering to look at my #ADSC (oceanic) data.
