DragonOS Focal Direction Finding w/ KrakenSDR + Boat (Steam Deck, GS66, DF-Aggregator, Kraken Dash)

In this video I share the results of the second direction finding tests conducted both from a boat and shore using the KrakenSDR.
The soon to be publicly released KrakenSDR web mapper and DF-Aggregator was also used in this video.
For this setup three stations where initially tested, however, for test two that was reduced to a Valve Steam Deck that was stationary inside an SUV with antennas on the roof and a G566 Laptop and antenna array setup on a boat, both running the KrakenSDR software. External power was provided in the form of a battery pack and cigarette lighter. All stations used cellular internet to share information with the two different mapping solutions.
The boat was mobile and utilized GPSD within the KrakenSDR software and DragonOS. The SUV was stationary and used static GPS settings. A hand held 1/4 watt radio was used as the transmitter and was stationary on the shore line.
A couple things to note that I did not fully cover in the video. The KrakenSDR cloud service has a resolution setting, I briefly pulled it up in the video, that setting is the number of grids per axis on the heat map grid. When setting up your antenna array and wiring, make sure to keep the cables together in a neat path with zip ties, just keep them as tidy as possible. A metal ground plate under the antennas is also a good idea, on the boat I just placed them on the deck which was carpeted. Also keep the extended antennas the same height. All of these steps will help obtain the best results.
In the final portion of the video, when I switched to DF-Aggregator,
I did not discuss in detail all the settings I was adjusting. I was basically reducing the settings so that I could see all intersections and points for the test. The GitHub page describes more about how to fine tune things. I recommend taking a look.
I'll add to this description as I think of more info to share.
