Do I need an RTL-SDR dongle to use Helioclock?

No – it’s entirely optional. Helioclock runs fully featured without
any SDR hardware at all.

If you do add an RTL-SDR dongle (sold separately, not by Helioclock),
it unlocks a few extra things: actual reception confirmation at
WWV/WWVH and NCDXF beacon frequencies (so propagation gets confirmed
because your own hardware heard the signal, not just because another
station reported a spot), plus the ability to open a full interactive
SDR receiver on the same device.

Think of it as a bonus layer for operators who want it, not a
requirement for the core product.

I have Helioclock running with an rtl-sdr (v3). i have the drivers for it installed as well, what else is required for functionality?
