Yeah, I suppose so.We've ALL started like that.
I think my longest continuous "aircheck" I recorded was a 60+ hour chunk of the online-only WQEZ recreation, not to preserve per se, but to split up into 1 or 2 hour chunks, with jingles and IDs stripped out so I can play them continuously without any interruptions.
Knowing what I do now, I wish I could go back in time and record a bunch of airchecks of my favorite stations. I had several VCRs and tuners I could've used to record several at the same time, so I had the tools, but the thought of making airchecks of radio stations using them never occurred to me (TV shows, on the other hand, I recorded many of).
