Do I have this concept of VOR right?

[z.khalid]

Just a few questions to clear my mind.
I'm still training.

If the VOR is behind me, I will see a TO indication to the back and a FROM in the front on my HSI on the FPD?

When looking at an approach plate and I see R-120 for example, that would mean radial 120 that's the pulse coming OUT of the VOR is that correct?
Which if i'm flying TO the VOR would mean its track 300?

Also, what exactly is tracking, and homing to a VOR.
How is it done?

Thanks guys.
