Raspberry Pi Configuration

One objective is to connect to the Pi over SSH from multiple host computers via direct ethernet connection. For example, in the field, I'd like to connect to the Pi using either my Dell XPS 13 or Lenovo laptops with a direct ethernet connection.

Here is a good resource: https://www.raspberrypi.org/documentation/remote-access/ip-address.md

Specifically, note the tip that you can SSH through a connected ethernet cable over the address raspberrypi.local e.g. ssh [email protected].

Note that this doesn't appear to work when simply hooking the Pi onto an ethernet connection attached to a switch going into my router.

Successful signal check 1692.7 MHz.

Had that classic Plateau look to it.

Bandwidth less then 28 kHz wide.

I think that this signal is from the NOAA EMWIN system.

NOTE regarding LNAs: The LNAs I currently have do not appear to be helping. I could only see the EMWIN signal after disconnecting both LNAs in between the antenna and the GOES Sawbird Chip as well as between the sawbird and the SDR.

Antenna --> LNA --> Sawbird --> LNA --> SDR == No Signal.

Antenna --> LNA --> Sawbird --> SDR == No signal.

Antenna --> Sawbird --> LNA --> SDR couldn't be tested as I couldn't get power to the sawbird while it was connected directly to the antenna (obstructed usb mini port for power).

Was unable to see signal at expected LRIT frequency of 1691.0 MHz.
