While tuning my Airspy software defined radio (SDR) at my location in Seattle, I stumbled onto this broadcast on a band meant for two-way radio communications such as police, fire departments, taxis, Family Radio Service (FRS), General Mobile Radio Service(GMRS), both analog and digital. I listened closely to the poor sound quality and managed to type in a Google search. and came up with “Harvard Sentences.” After listening for awhile I noticed certain lists of sentences were playing in a certain order and then looping. At approximately 4 minutes and 43 seconds list 59 begins “Every word and phrase he speaks is true.”  Then after list 57 “Prod the old mule with a crooked stick.”  at about 11 minutes and 12 seconds, the groups of sentence lists repeat in the same order. I guess a beginning and ending could be anywhere in the groups of sentences, but to me, it seemed like  “Every word and phrase he speaks is true.” is a logical starting point. Here’s an interesting article about the “Harvard Sentences.”

I don’t know why this is being broadcast, but in the late 1970s and early 1980s, I recall 454 to 455 and 152 to 153 megahertz being used by the telephone company for mobile phone calls. This, of course, would have been before cellular. Here is a full list of sentences. Any thoughts on this matter?

The first recording was made on April ‎19, ‎2017, ‏‎2:39:11 PM and this last sample audio only recording was made over 11 hours later. This recording shows the loop point where list 57 ends and list 59 begins. I think “085709Z” in the SDRSharp file name is the universal time. In other words, 8 hours, 57 minutes, 9 seconds is 1:57 AM and 9 seconds pacific daylight time. The “Z” is for Zulu, which is another name for universal time.
