Oh PLEASE let this be the impetus for starting up Sparkfun Canada!

I've finally had some luck with a command line tool I found at:
The problem may have been that my wav files were not PCM mono wav files. I used another audio utility to convert them (Goldwave), and then a batch file that used the command line utility to make AD4 files. I'm going to try it tonight....
I'm unable to get the audio conversion app to work. The app installs fine, I can load my .wav files, and when I click the Encode button, it says it's successful, but no AD4 files are created.
I've downloaded an eval of GoldWave, but I don't see any options for AD4 files as output on the Batch Conversion utility. Perhaps one of the other ADPCM WAV formats will work if I change the extension?
Any tips? Thanks!

Interesting. I just had the same issue with the example that comes with the TinyGPS library that Mikal wrote (yea, pretty sure he's seen an Arduino or two :) I'm using the EM406a gps.
Why does this happen? Does the shield reverse the RX and TX pins somehow? Just to clarify, I was using the sketch 'Test_with_GPS_Device'
With the unmodified sketch, the serial monitor would output:
"Testing TinyGPS library v. 9
by Mikal Hart
Sizeof(gpsobject) = 103"
Once I changed the line:
NewSoftSerial nss(2, 3);
NewSoftSerial nss(3, 2);
I got the correct output with all the coordinates
No public wish lists :(
