Re: Tips on interfacing I/Q data into quisk?
¿ªÔÆÌåÓý
Hi Jim,
I was looking at version 4.2.28 since I had the source handy, and was looking at sdriq.cpp as you recommended.? I thought before I got to hacking around to try and get something going, I should update to the latest?version, so I did from github.? Now I cannot
find the sdriqpkg directory or sdriq.cpp.? ?Can you clue me in on what I am missing?? It looks?like you moved everything to Python.? You had a nice "API" in the old C++ file.? Is Python going to be fast enough to handle the approximately 3.5 Mbit/s I am expecting
over /dev/ttyAC0?? What do you recommend now?
Thanks & 73,
Rob

Cool!? Thanks Jim.? I will try and decimate it down to something more manageable on my end,? It is a relief to know Quisk can handle some small mismatch.

>>Do you have a feel for the best way to deal with the fact that my sample rate is going to be 48.0460 kHz, not 48 kHz?
Quisk can correct small rate differences itself. Otherwise the SDR-IQ rate correction can be used. We will have to deal with this once we have the hardware available. Jim N2ADR |
