Bank Holiday Monday in Scotland felt odd not hammering away on OscarWatch, but I did get a few visual bugs sorted out; I am feeling super happy with it now. github.com/magicbug/OscarWat…

OscarWatch is 25 days old today. In just under a month, I've managed to build a fully functional satellite tracking application for operators that's multi-language and supports a range of rigs. Not bad at all.

If you are using CAT Lead to try keep on top of doppler at TCA->MID LOS its still sucky and needs some more work

IC-821H support is untested; I don't have one, but the CIV commands look correct. If you have a radio test, report any issues

For those asking for TX Offset as well as RX Offset its a simple switch from the next release.

An unpopular design decision in OscarWatch is that it won't support radios operating in semi-duplex mode, for the simple reason that it's a terrible way to use satellites.
If you don't have a radio that is duplex, it will, however, control most of the modern radios as a pair.

OscarWatch Lead Doppler Function: near TCA, range rate changes fast - CAT lags behind. Lead ramps in only on the steep middle, not AOS/LOS (50ms cap). Grey dot = on, amber = leading. One RX offset tweak; the rest of the pass tracks. 🛰️

Needs a few more validation passes tomorrow but just tried it on FO-29 over the Atlantic and it was solid the whole pass
