I am happy to report that I now have the Pi Pico able to work with the RPi5 SBC. The issue was that the package to recognize the Pi Pico has to be manually loaded into the QUISK directory. Once installed what should normally happen is that when QUISK is executed that radio should show up on the menu. It didn't on the RPi5 SBC.
It was a mystery as using essentially the same process the radio did show up on the Windows 10 machine. Then, I decided to closely read the instructions where I spotted something you needed to do differently for the Linux install. Dah RTFM! Suddenly the MHST rig is in the list. I still have a few warts to polish off but a huge step in reducing the size of the rig with the bonus of the features in the Linux form factor versus the Windows 10.
One really important Linux feature is the Pulse Audio Control Panel that is loaded in a terminal like this.
sudo apt-get install pavucontrol
This control panel gives you a whole series of adjustments and selections with regard to the two sound cards. This panel has the Mic Gain and overall Audio gain level sliders as well as the line levels for the I/Q channels on both transmit and receive. #11 is not always the best adjustment.
I did find with the package developed by the VWS that some sound items on the QUISK configuration menus do not show up automatically as a drop-down menu but must be added manually. I cannot fault their package as I am using their software for a completely different application and rig. The manual entry process did work.
Another issue was the Com Port. In the Windows 10 I was able to determine the 2nd Pi Pico is now com22. The 1st Pi Pico, I smoked, it was com21 and those com ports must be manually entered in the QUISK Configuration set up. The Linux com port is a bit trickier and is entered as /dev/ttyMACO
It is basically there but there are still some features requiring a bit more work and so we press on.
It is understood that some big thing will be announced from 1600 Pennsylvania Avenue on Tuesday -- how appropriate as that is April Fool's Day. T. S. Elliot, a noted American author and poet once said that April is the cruelest month. Maybe Tuesday's big news is more in line with T. S. Elliot.
Where do all those who were RF'D go for employment. There is a timing disconnect between tariffs to create more US businesses and when those businesses would be in full production to absorb displaced workers. Two years is a very optimistic time horizon. Surely someone who attended Wharton would know that (from Econ101). So, what do us common folk do for two years?
Keep in mind those who were RF'D were not bad employees, yet they are categorized by one individual as Waste, Fraud and Abuse.
Them that know can make it go.
