Yes that's true , but for HF , then Doppler and delay need to be tested or the mode will not survive transit and 500 has phase distortion in qsb , could be seen using Murrays psk propagation time delay measuring software seemed to explain why psk31 did not work very well at range (or over the pole on hf ?)

Try the tests using the Path-sim propagation software , that's a good universal test instrument, free to download
