Youtube comparision standard HF packet, 300 baud BPSK, Robust packet

While it is not a "scientific" comparison, there is a good video that compares the throughput of running HF packet, 300 baud BPSK, and robust packet at https://www.youtube.com/watch?v=FApm2thQqIo&feature=youtu.be 

Many thanks to K2MO for putting that together!

Not to be the complete spoiler, the results indicate that 300 baud BPSK outperforms standard HF packet (as expected) and robust packet outperforms 300 baud BPSK.

Robust packet is furnished with proprietary HF modems that run from approximately $300 to $1800 depending upon other features included (such as Pactor).

So, if you don't want to spend $300, but need a boost in performance in HF packet, 300 BPSK is the winner with a price of $0.  All you have to do is download the UZ7HO program and use it as the "modem" on your favorite terminal or APRS program.  In addition to the standard 300 baud and 1200 baud packet flavors, UZ7HO now supports both BPSK and QPSK.  The BPSK is a strong performer on HF, while the QPSK allows up to 4800 baud on a STANDARD radio as opposed to a "9600 baud" mode radio.
