qrpTracker 'satpack' First QSO

10 minutes ago, my qrpTracker project passed its acid test, a real satellite QSO. Hearing rather good sigs from SO-50,  I decided to reply to KC4KMY's call. My side was hampered with using a 1/4 wave vertical as an antenna, causing his sig. to be heard only about 1/3 of the time, but it was good enough for the log. This means that the following automated functions of the latest 'satpack' code are working well: Downlink tuning Periodic uplink tuning of the FT-817, with switching VFOs. This is in the manner of instantune, HRD and SatPC32 CTCSS tone encoding to ensure access to SO-50 and similarly equipped radios CTCSS was only completed this weekend, so I'm delighted that the whole package is in place.

Lots of progress with 'satpack', my Arduino-based full-doppler-tuning satellite tracking application. On the right, you see a cardboard mockup of the pcb. On the software side, I've checked a fully working version of the code into the SVN repository.
