Excellent point, Drew -- SDR's can visualize and record the entire passband. I posted screenshots of the AO-07 and VO-52 passbands during field day last year, they're on my blog at:

Have fun!

I've recorded and posted SDR recordings and screenshots before. Might be more accessible for folks as a simple youtube video tuning from one end to another....of course, most of the time everyone is piled up in the middle 20khz.

I have been asked by ICOM to webcast field day this year.
Unrelated, but it would be great if someone with a good satcom station recorded the passband of FO29. Not so much to get individual QSO's but to grasp what a full wideband transponder can carry.
IE, tune the passband from one end to the other at a constant rate.
Then again, and again, and again at the same rate. Maybe separate files for each scan so we can tell when a complete scan begins and ends.
This would give those who are unfamiliar with wideband linear transponder operation what the capability really is under FD loading...
Just a thought.
