Not only those that are perfect, but those off-air, complete with noise, interference and even tape recorder irregularities.
Remember the maximum single file upload to this board is 20MB and the maximum number of attachments per post is 50. (I know, wishful thinking).

I think after 17 years we can give up on that! These things happen. Often I think, "Now where did I put such-and-such?" I search high and low and after a while I give up and presume it got tossed out or lost somehow. Whatever, you end up wasting a lot of time.
I'm looking for old(er) material to test the NBTV/SSTV-625 up-converter. I can generate 'perfect' SSTV audio files, I guess I could add in some white noise suitably filtered. But there's nothing quite like a real off-air recording to put this thing through its paces.

Even dogs barking, passing cars and motorcycles...depends on your location to a large extent. Even a TV or radio playing in the background. Worth a try. An AM radio tuned away from a station to pick up static, and here at this time of year, thunderstorms...trouble is I don't have an AM radio!
