Really? For history? Somehow I can't see archiving "Cleanup on aisle 5" but maybe that's just me.
I archive recordings of many conventional frequencies, and Trunked systems. majority of people may not care about "cleanup on isle 5" but years from now, long after such monitorable activity is gone, someone may find it interesting to hear what they sounded like.
theres so much ham/commercial/police/FD etc.. i wish i had recorded in the 80s and 90s.
If i record a frequency such as Walmart long enough, there's always going to be some funny comment or something said that they think no one can hear.
sometime s those comments or discussions are Gold. I don't always know about such comments until I process the audio months or years later.
about 6 years ago, i went thru a drive thru, recording them while telling them my order, i was being silly and requesting odd things that they couldn't do like putting a apple pie inside of a big mac. its fun make such requests, but their internal headset comments about me are really funny, thinking no one could hear them.
same for HME COM400 Drive thru analog systems, the 457.5125 457.5375 ETC... I keep an active database of all known analog drive thrus in central and west central Florida, I try to travel to them each year to record each one for a example and update my Database with the ones that have gone out of service in the last year.
when I was a teenager 30 years ago in my early days of radio I used to jam and interfere with drive thru systems and as an old guy today I regret that, I've actually regretted it for many years. so my positive contribution is to record the remaining analog locations for history.
Taking a trip to Tennessee in a few weeks, ill have all my recording scanners with me, recording everything they can hear while driving thru each state. they make separate directories for every frequency and PL/DPL/NAC/CC/RAN OR TG if Trunked.
I really enjoy the analog country police and FD departments out in the boonies. hearing their twang voice. eventually those analog police and fire departments will be digital (possibly encrypted) and having a recording of the analog might be quite valuable to some people, I Know I will appreciate all of it, and look forward to sharing as much as i can with anyone interested in radio history.
there's a guy named Evan Doorbell on youtube, he was a Phone hacker in the 1960s to the 80s. not really unusual in itself, but what was unusual? He recorded so much of his Phreaking and now in his 60s hes making audio recordings on youtube with a narrated discussion about what hes doing to operate the network and what the old networks were doing. so fascinating. my recordings may be like that for the radio scanning community many years from now.
