		+	'''05. of November 2025: New location found'''
		+
		+	After pondering about options for far longer that intended, the decision for a new location was made. There were some dependencies which needed to be met. A grid connection. At least 100+ meters away from where people live (strong fields is an issue with lots of modern multimedia devices and it might cause issues which lead to authorities to show up). And an option for a larg(er) antenna. I wish I could tell about the structure that will be (ab-)used as an antenna. Likely the most hillarious thing. But I guess sooner or later the site will be demolished as well and after that it can be revealed.

	- '''Approx end of November 2023 (ongoing)''': It goes down with the location rapidly. Lots of activities regarding scavengers. They now even go for the thin cables that were left untouched before. Need to re-route a new cable even more hidden. It's winter. Snow and cold. The roof is slippery AF. Fixing the issue will take until the end of the year I guess. But hey, the big scorch mark on the cut cable was satisfying to see. Someone got a nasty suprise.		- '''Approx end of November 2023 (ongoing)''': It goes down with the location rapidly.

		+	- '''16. of February 2024''': permamently offline. I managed to retrieve the whole setup last minute. Demolition work has started and the Antenna (modified lighning rod) was already flat on the roof. Bit of a shame. Right now I'm on the search for new location. Could become hard. Feels like all objects that lay dormant for decades became an interest for new housing projects recently.

	- '''07. August 2023''': A new site was found. Setup is in progress. But it's expected that the location has to be changed again within this year. A lot of locations lay dormant for years. But oddly, since the end of the Covid-19 pandemic, a lot sites got demonished (or became marked for demlishing). Turns out a lot of properies got sold during the pandemy and will be used for new objects soon. It becomes more and more tricky to find suitable locations (especially with power available). Additionally, more and more vlogs (Video Blogs) on S1ocial Media about lost places results in an increasing number of people on locations. And with such comes more and more vandalism. Hence, running on Solar might become tricky as well. There's more lost objects available outside my home town, but most require at least a 45-60 minutes drive by car one way. Which I struggle with. Time and ecological wise.		- '''07. August 2023''': A new site was found. Setup is in progress. But it's expected that the location has to be changed again within this year.

-	* A 9.216.000MHz ~~crystal~~ allows to both derivate a 50Hz (20ms IRQ) Baud RTTY signal and also regular RS232 Baud rates from it (for debugging purposes).	+	* A 9.216.000MHz cryshttps://www.hfunderground.com/wiki/skins/common/images/button_image.pngtal allows to both derivate a 50Hz (20ms IRQ) Baud RTTY signal and also regular RS232 Baud rates from it (for debugging purposes).

	* Class E introduces quite some stress to Switch Mode Power Supplies when operating in CW mode. Experience from the recent years has shown that output capacitors will dry up rapidly or become short, oftean leading to a blown up power supply. Use a power supply that can at least provide double the amps drawn by the transmitter. Adding additional high capacity ceramic caps (2-3 x 10µ/50V, usually 1210 footprint) accross electrolytic caps also helps to reduce the stress a great deal. A classic transformer based power supply works also great. Be aware that any 100/120Hz ripple will be audible as AM modulation, thus leading to a higher signal bandwith.		* Class E introduces quite some stress to Switch Mode Power Supplies when operating in CW mode.

		+	Power was still available in the heavyily damaged fuse boxes in the basement. Giving up was no option. Wire stubs sticking from the walls were rang out to find a connection from the basement to the staircase through the walls. Single wires we ran through the pipes going through all 13 floors. Took a quite some time. But eventually power was available on the roof again. Sadly again, demolition works suddenly started two months after the installation. Thus, everything had to be removed again. You gain some. You lose some. Sigh.
