I've read good things about Direwolf so I gave it a try on a Raspberry
Pi. Did a fresh install, followed instructions in Raspberry-Pi-APRS.pdf
All of the software install went smoothly. Direwolf starts, and I get an
average of 4406700 samples per 100 seconds. It only misses a few samples
so I guess that is OK.
Past 100 seconds, 4406720 audio samples, 0 errors.
I use a cheap USB sound device. dmesg shows it as follows;
[ 3.367735] usb 1-1.3: new full-speed USB device number 4 using dwc_otg
[ 3.490205] usb 1-1.3: New USB device found, idVendor=0d8c,
[ 3.502585] usb 1-1.3: New USB device strings: Mfr=0, Product=1,

[ 6.247566] cm109: CM109 phone driver: 20080805 (C) Alfred E. Heggestad
In direwolf.conf I have;
arecord -L doesn't show any plughw devices, just the default,
sysdefault, and a bunch of surround devices.
When I start Direwolf the LED on the USB sound device starts flashing,
so far so good.
But I cannot get Direwolf to decode any packets. I've played around with
input gain settings in alsamixer (made sure I selected the right audio
device with F6). mic and capture device setting are at maximum or close
to maximum, but still no luck.
Is there any tools like an oscilloscope or spectrum screen as with the
old linux soundmodem? Some sort of adjustment tool with user feedback
would be nice. How else am I to know what is a correct level setting?
Help please! I'd appreaciate any pointers in the right direction :)
