Possible bug LORAN_C extension #30

Open G8JNJ opened 7 years ago

G8JNJ commented 7 years ago

I've noticed that the Loran_C extension doesn't always sync to the correct time slot.

Stopping and restarting the extension a few times usually fixes it, but if the signal is not known it isn't really possible to tell if the timing is correct (or not).

Regards,

Not documented except in the Kickstarter update describing the extension, but you can click in the Loran-C display to shift the clicked point to the leftmost edge. For example with Anthorn, click just to the left of the master (group with 9 pulses) and it will shift to the beginning of the red "master" window. The slave group (8 pulses) will then appear properly somewhere in the yellow "Y" window.

A future extension version that has more time resolution could detect the master automatically.

Ah OK - worth knowing.

Not much Loran around these days :-(
