step 1: jailbreak your Kindle

mobileread.com is your best resource here, follow the instructions from the LanguageBreak thread

I didn't really follow the LanguageBreak instructions because I didn't care about most of the features + I was curious to do it myself, but the LanguageBreak github repo was invaluable for debugging

Introduction

Here is a collection of tips and tricks I've picked up about doing performance analysis on Node. Included is a build script that should get a base install of Ubuntu fully functional and ready for all the things we'll be going through.

The script pulls a lot of code from the latest master of each repository. So it's possible that something may fail, but to date I haven't had any issues.

First, go ahead and run the script. Then go take a nice long break. It'll

	"""Use WSJT-X decode time offsets from ALL.TXT to sync system clock through chrony SOCK.

	Digital radio modes like FT8 require system time to be at least coarsely in sync.
	Normally of course you can stay in sync via NTP, but I find when I am offline (e.g. at a
	remote field location for POTA) I get out of sync pretty often. You can reset system time
	manually (chronyc manual on; chronyc settime; chronyc makestep ...), but I have had cases
	where it still drifts out of sync repeatedly and disrupts QSOs. It is also more critical to
	be in sync for FT4 compared to FT8, and FT4 is frequently useful when trying to run QRP on
	crowded 20m.
