1980's -
Lysaght, LeBeau,Taylor, James
|
| 70's/80's Rogers/Thayer, etc. A great collection of classic bits. At beginning hear a 1975 GE Tube radio being the clearest recording available. Later a domestic with gun = item1. |

Reilly Shooting, Addison St. Audio from all channels in
dispatch. What a mess (courtesy Tom Thayer) |
01-18-85 A recent find - An "Oldie" - Clip from a reel to reel "off-air" recording 6:22 mins | 70's-80's(2) - A mix inluding brief clips dated back to 1973; the earliest so far. *Note the radio "skip" from other stations. A phenomenon in late summer during 11 year sunspot peak cycles on VHF Lowband. |

1994
- Switchboard and Radio sample

Nov.1993 - Switchboard and Radio sample (2) | Future use |
Recordings are prior to 2005 full time radio encryption.
Non-Encrypted broadcasts are available to the public on home
receivers/scanners/internet and permissible under FCC rules
See bottom of page for more details about Bristol's encryption and it's
disadvantages

Exhibit 1 (audio/video)
|
1970's - 1980's |
|
A montage of vintage BPD radio traffic and random photos/slides. (Originally constructed in this format to permit Facebook posting). Parts near the beginning were from the 70's and recorded off air from the department's 50's vintage GE Tube Radio system, at 39.42 MHz, with a fuller sound than is available from the current encrypted 800 system.

Exhibit 2 (audio/video)
|
1990's: |
|
This exhibit is mainly switchboard communications that makes an interesting mix. Source: Analog Dictaphone tape recordings from 4000 and Veritrac 9000 series. Radio: Motorola 800MHz trunked system and switchboard. Final audio shown playing live inside "Cooledit Pro" software where it was mixed. |

Don't let rare recordings get lost in time. Have some old cassettes? reel to reel? with even short related clips? Let me know and I'll digitize them, edit out the unwanted stuff and present it here. |
Not
enough?,
Listen to LAPD, live (They don't care if everyone listens.
No encryption there!)
Or Here: NYPD - Bronx, live feed or many others. Almost no-one uses encryption.

Bristol uses a Digital + Encryption Radio System. |

*A note as to the irony - As if criminal masterminds in the Bristol area would plan their capers in concert with electronic equipment to elude the Bristol Police is beyond comprehension. It sounded good when Motorola presented that bill of goods to the city for a hefty price tag even though there has never been a single recorded case in Bristol's history of criminals using scanners to foil the police. The result: inferior communication quality. Delayed sound, garbled audio, reduced coverage, missed signals. All byproducts of digital encryption. It is a poor compromise that hinders police communications and reliability. For increased reliability and clarity of communications the system should ideally be full time non-encrypted yet able to switch to encrypt mode in rare cases involving swat/ERT surveillance or extremely sensitive broadcast information, but even then, who's listening these days?, No one. The irony therefore is that getting something "better", means it sounds "worse" and is less reliable. Even plain digital transmissions sound "worse" compared to analog because they use a narrow bandwidth with restricted frequency response. Adding encryption adds another layer of fog further restricting an already low quality. Digital is becoming industry wide now but encryption has always been an option and one that hasn't proven effective. Several police departments in CT and others around the country are turning off their encryption for safety reasons. See: http://newsok.com/article/feed/1090399.
