When using the Hermes-Lite2 at a remote location over WiFi, the Tx buffer may underflow. I added another line to the Config/Status screen to show the number of Tx buffer errors. Jim N2ADR

I just found ?an interesting discussion about this subject in the documentation for the WDSP signal processing library that quisk uses. The Github for it is at https://github.com/g0orx/wdsp (

Thanks Jim, This sounds very encouraging. I only need receive, and the sample rate will be as close to 48 kHz as I can get it with the clocking on the Pico. I am using a PCM1808, but the timing

Please take a look at function quisk_process_decimate() in quisk.c. Quisk can accept a variety of sample rates even if they are not multiples of 48 ksps. It decimates by an integer to a rate close to

Rob Have a look at something called a Costas loop. It should get you to your goal. Of course you will have to integrate it into the FPGA code. Every one up for the challenge? It's a PLL that locks

Mario, check out my Teensy SDR transceiver project which uses the SGTL5000 (other codecs possible).? ?Maybe it helps fill in the radio UI/Control aspect you mentioned to keep your project moving

Hi all, I think it's time for me to jump in again... I've been trying to deal with this problem for some time and am having some good luck in solving the problem for my own hardware design. Perhaps

And I do not understand why I found quisk v.4.2.23 installed in c:\users\my name\AppData\local\Programs... at the beginning of this attempt to repair and upgrade. I had always used the "pip install

I uninstalled again v.4.2.24 and reinstalled 4.2.23, which complained when clicking quisk.exe that there were no quisk_hardware_hl2_oob.py file. I downloaded it from github, pasted it in \hermes and

Still not working. When clicking on quisk.exe it complains that it does not find hermes\quisk_hardware_hl2_oob.py file but this file exists on my didk in the hermes directory. 73 - Pierre - FK8IH

I found several directories related to quisk: - 11/23/2023 in C:\users\JC\AppData\Local\Packages\PythonSoftwareFoundation.Python311.....\LocalCache\local-packages\Python311\site-packages\quisk with

Hi Jim, Thanks for the expertise! I think I can get to 1.017253 the correct frequency if I use the standard 125 MHz Pico frequency. It is very easy to change though. Of course, it cannot be changed to

Hello Pierre, Try searching your drive for another Quisk installation. Search for "quisk.py". If that doesn't work, uninstall Quisk, delete its "quisk" directory and re-install. Use this command:

About python quisk.py : - if I right click on it and left click on execute with python3.11 it opens quisk v. 4.2.23 - if I go the the good directory and types python quisk.py it aborts, see the

I have never had success with resampling I/Q data. The balance is degraded and images appear. How close to a multiple of 48 ksps can you get? Jim N2ADR

init_py shows v.4.2.23

Hello Pierre, This file is not Quisk. It is a startup script that runs a program like "python quisk.py" to start the real quisk located elsewhere. Search for "quisk.py", the main program. It is

I'm looking at using a Raspberry Pi Pico W to collect ADC data and it appears that my clock will not be able to get an accurate 1228800 Hz clock. I will be sending this data over UDP to quisk, and can

Jim, I got the same screens as Mike and also upgraded setuptools, all others already up-todate. 73 - Pierre - FK8IH

Jim, I checked my Python version and I have only 3.11 installed. I had some 3.9 and 3.10 directories remaining but they were not effective and I deleted them. I uninstalled quisk then reinstalled it
