[Hackrf-dev] HackRF-dev Digest, Vol 42, Issue 3

I have a HackRF one, and I'm reading up on the Yard Stick One.  I'm
wondering, if I have the HackRF One, does the HackRF do the same thing as
the Yard Stick One?  I read that it's based on the CC1101 chip.  I have one
of the CC1101 modules, so how would having a Yard Stick One benefit me?

I know both are only half duplex so maybe with both you have full duplex.
Since I already have various RF transmitters and a CC1101, perhaps a Yard
Stick One would not benefit me?

The only reason to buy a Yard Stick One that I could think of is so that I
can transmit at the same time as I'm receiving on the HackRF.  I think I
can accomplish this same thing with my CC1101 module?  Perhaps there's more
tools developed for the Yard Stick One and that's the main benefit?
