New blog post: Time-dependent delay in @gnuradio. I have added a new block to gr-satellites that performs a time-varying delay. This block works similarly to the Doppler correction block: the delay versus time is defined by a text file prepared beforehand. In the post I explain some of the implementation details of this Time-dependent Delay block, and how to use it. Read more: https://destevez.net/2025/05/time-dependent-delay-in-gnu-radio/
