One of the annoying things about the HackRF is that its only 1/2 duplex. It could be a receiver or a transmitter but never both at the same time as a transceiver. Not anymore. SDRangel now has a new feature, the PTT button that automatically switches from RX to TX and back again. To use it is very easy. Setup your source device, then setup your sink device, click the play button and then when you hit the PTT button you will switch from RX to TX like a pro,
I have been playing with this new feature this morning using a 2m handheld and the HackRF and having QSO’s with myself at the milliwatt level LOL. The received audio in SDRangel sounds rather rubbish, i am sure I have some setting wrong somewhere, but it sounds thin and at times distorted. The transmitted audio does sound a little better.
As far as software goes, its good to see the developers of this continue to improve and expand it. There are also a lot of new demodulation types as well since I last updated it.
