problem with receiving text string

[ciucki]

Hello everyone I'm trying to implement an  amplitude-shift keying with Labview, I'm new in the forum, I hope you can help me, the problem is that I would like to enter a text string and then receive it, but the problem is that even if I enter an ideal channel I do not receive string correctly but 3 characters wrong. Can anyone kindly help me? I attached here the project, thanks!

Hi ciucki,

it really would help to get more answers when you would attach a downconverted version of your VI! (File->Save for previous)

LV22Q3 isn't that used so often right now…

Ok, I attached an LV2021, thanks

Please convert to 2020 or lower.
