I was sharing on our local "all things fun and digital" discussion
list about the progress with the sound card modems such as UZ7HO and
Dire Wolf, when one of the uber-techy members responded with:

>> Without some measured Eb/No
>> curves, you don't know where you are on the "crappy scale".  There is
>> absolutely no reason why you can't generate an Eb/No curve with the

>> with any radio/modem combination.

I know there have been some significant tests (wa8lmf pages, DireWolf
user doc) against a 'standard' CD of aprs traffic but is there any
more scientific Eb/No data as mentioned?

Even more intriguing would be the test results at higher speeds such
as 9600 and now 19200 with UZ7HO.

Thanks,
Bill, WA7NWP
