Hi,<br>
<br>
I've read good things about Direwolf so I gave it a try on a
Raspberry Pi. Did a fresh install, followed instructions in <a
href="http://home.comcast.net/%7Ewb2osz/Version%201.0/Raspberry-Pi-APRS.pdf">Raspberry-Pi-APRS.pdf</a>.
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.<br>
<pre> Past 100 seconds, 4406720 audio samples, 0 errors.</pre>
<br>
I use a cheap USB sound device. dmesg shows it as follows;<br>
<br>
<tt>[ 3.367735] usb 1-1.3: new full-speed USB device number 4

In direwolf.conf I have;<br>
<pre> ADEVICE default:CARD=Device</pre>
arecord -L doesn't show any plughw devices, just the default,
sysdefault, and a bunch of surround devices.<br>
<br>
When I start Direwolf the LED on the USB sound device starts
flashing, so far so good.<br>
<br>
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.<br>
<br>
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?<br>
<br>
Help please! I'd appreaciate any pointers in the right direction :)<br>
