now the ID is CW and PI4 code It was JT65C2 for digital ID before It took some time to decode the new digital ID in PI4 code http://www.rudius.net/oz2m/software/pi-rx My fir st impression is that JT65C2 that was used before is decoding quicker and better. Possible the PI4 will be inproved It is the fir s t time I used this PI4 never heard about it before. Need to read more about it. JT65C2 did decode fast e no ugh for a beacon 10seconds? PI4 code will have some mo re options to send extra data and other things.
