Softrock Ensemble Afternoon 6
Running QUISK on Ubuntu 10.10 (32bit)

I have been struggling to get the SDR software to run on my laptops.
After some screwing around last night and then again this morning (Linux+XP VM, XP on a Netbook, etc) I decided to spend sometime trying to get QUISK working under native Linux.
Here are the steps to make it work:
I was able to launch QUISK (quisk.py) and then PCB initially with my signal generator as the source. Once I was able to confirm that worked I was able to connect the PCB to my 40m dipole and hear some CW near the bottom of the band.
Magic... SDR reception with Ubuntu 10.10+quisk on my laptop.
I am still battling a bit of a pulsing or surging in the audio after a few minutes that seems tied to CPU performance. For testing purposes I have proved that I can receive signals so I should be able to move on to the next building steps. (I can come back around to work through the performance issues later.)

I have been struggling to get the SDR software to run on my laptops.
After some screwing around last night and then again this morning (Linux+XP VM, XP on a Netbook, etc) I decided to spend sometime trying to get QUISK working under native Linux.
Here are the steps to make it work:
- I added a USB soundcard to the laptop (driving some external speakers)
- I have the Softrock Ensemble RXTX audio out connected to the laptop's internal Line/Mic "in" connector
- I have the Laptop and PCB connected with a USB cable
- I have a bench power supply providing 12.9vdc to the PCB
- I then I copied the conf file:
cp home/me/quisk-3.4.12/softrock/conf_rx_tx_ensemble.py /home/me/.quisk_conf.py - I then updated the .quisk_conf.py file with the following settings:
sample_rate = 48000
name_of_sound_capt = "hw:0" ##This is the internal sound card
name_of_sound_play = "hw:1" ##This is the USB sound card
