I now agree with you. I was perplexed that the recordings would start in mid broadcast, like the old tape ran out and a new one put in. It is now clear to me that in general, the local radio stations were not recording anything when they heard about the assassination, and while concentrating on getting the news and broadcasting it, took up to an hour or more to setup and start recording the broadcast. I now believe, so far as I know, that no tape, once made, was lost. But it is also clear, that in many cases, no recording was made during that first hour.
It is now clear to me that in general, the local radio stations were not recording anything when they heard about the assassinationPray tell, just how did that become clear to you?
I was perplexed that the recordings would start in mid broadcast, like the old tape ran out and a new one put in.Which only tells me that you don't really understand how an output recording system used to work, back then. You seem to be under the impression that somebody had to change tapes ever so often, when in fact the system used a big real tape that was slowed down so it could record a full 24 hour output on one tape. There normally were two machines, with the second one starting a minute or so before the tape on the first machine ran out.
I doubt a police officer would overhear and reporter talking and call dispatch to report that “NBC News is reporting DOA.” The fact that he was using the radio means, to me, that he wasn’t at police headquarters but was patrolling in his vehicle. Officer E. G. Sabastian isn’t going overhear a reporter at headquarters, walk past the dispatch office, go the garage, get in his squad car, get on his radio and report to dispatch that “NBC News is reporting DOA.”
Why would the reporter that Sabsatian possibly overheard be at DPD headquarters? Cops on the street meet people and overhear conversations all the time. Sabastian may well have known the reporter to be a NBC News employee, and when he heard him say the officer was DOA he simply got curious and wanted to get confirmation by calling it in. Since names of people were/are not normally broadcast on police radio, he may well have gotten around that by saying "NBC News is reporting..."
“NBC News is reporting DOA” means hearing a media broadcast, either over TV or radio. And we know it wasn’t TV. And he wouldn’t have been watching TV. And likely based on the voice of an announcer who reported for NBC, or at least often reported for NBC, but sometimes ABC. Like an announcer for either WBAP or WFAA. It would not have been WBAP but it might have been WFAA.
“NBC News is reporting DOA” means hearing a media broadcast, either over TV or radio. No it doesn't. Not necessarily anyway. Yesterday on CNN I heard a reporter say "tomorrow the New York Times is reporting....."
By the way, was E. G. Sabastain assigned to chat up reporters and report back to dispatch what they were talking about?
No.
So what? Was Victoria Adams a police officer? Yet she still overheard a message on the DPD radio. Regardless of what Sabastian's assignment was, that doesn't preclude that he overheard somebody saying a fellow officer was DOA and wanted to check with the DPD dispatcher if that was true.

1:25
75 (Ptm. E. G. Sabastian) 75 is at Forest and Central
which I interpret as Officer Sabastian is in his patrol car at the intersection of Forest Lane and North Central Expressway, several miles north of Dealey Plaza and police headquarters and not likely to encounter any reporters. And reports from “NBC News” has to be coming in over the radio.
You can interpret that as much as you like, but it is meaningless. If he had heard a report on the radio he would have known that it was Tippit who was DOA, but he clearly did not know that because he asked the dispatcher "That the officer".
Another point of interest is this. Let's say you're right and Sabastian did hear it on the radio at 1.25 or just before that. According to the official narrative, Tippit was allegedly shot at 1.14/1.15 and picked up by an ambulance at 1.18. The drive to Methodist Hospital from 10th/Patton is about 4 minutes, which puts the arrival of the ambulance at 1.22. There were no reporters with the ambulance, only Davenport's police car which started following the ambulance en route. Back in those days reporters had to call in stories by phone, so for the story to be broadcast at no later than 1.25, there were only three minutes, after the ambulance arrival, available for a reporter to get to Methodist Hospital, talk to a doctor, find a phone and call it in and get the story on the air..... Not very likely...
Now, if Tippit was really shot at around 1.06 or 1.07 it would be a different matter, but I don't think you want to be having that discussion....
