Implemented a feature I wanted to get to for a long time: separate heartbeats for the DX and the PC link to Club Log's real time livestreams. A little morse animation for good measure, too!

Just renewed my FCC Amateur Radio license for another 10 years, until 2036. Can't believe it has been 10 years since I studied, frantically, to prepare for the written tests. Now, I am Team Leader for a VE group, testing other hopeful new HAMs.

Updated the Club Log gateway (the power tool for real time uploads, with edits/deletes and satellite link efficiency built in). Squashed some TCP deadlocks and also improved the debug mode to make failures easy to debug. Also sorted kHz/MHz units from N1MM

Tried a simple light pollution filter. It claims to reduce wavelengths that give a muddy beige cast. I'd say the result ooks pretty good - the glow is from the nearest town. Handy when conditions and location are less than ideal, but about a stop darker than the lens
