How about an amateur trunked network?
I am interested in converting the 440 repeater
band to trunking. It would allow more folks, not that we are seeing that much use as it is, on the bands plus allow us to have talk groups that would be either linked or local. In many cases, instead of a number of repeater sites in a county, it would be only one with multiple repeaters on a single tower. Unlike cell phones, there is little need for low power thus multiple tower sites. Having to maintain a single site in each county would reduce cost (if we can get hams to work together, sometimes hams are too "libertarian" thus it is even hard to organize them for pizza and beer). European police trunking radio is in the 400 to 500 Mhz region which is far better than the 800 Mhz trunking that is being down here in the US. |

I'm familiar with amateur radio, repeaters, etcetera, but what is a "trunked network"? Heard the expression, just don't have the vaguest idea what it is. Bob k5qwg |

Using a digital code, a user group (ie talk group) be assigned a repeater for each push of a mike. Thus the repeaters are constantly shifting but to the users it sounds like they have a private channel. Some trunk systems have over a thousand talk groups (Seattle). It is also possible to like tower sites into a state wide system. For any user, it would sound like he was on his home system. Normally there is only one tower site in a county. I use a Motora Maxxtrak in my business, and we talk on two private channels -- I've been using trunking all this time, and didn't even know it :-) Bob k5qwg |

I am interested in converting the 440 repeater band to trunking. Well the most economical way today would be LTR trunking. The cost of a motorola or EDACS trunked system for hams as a group and for individuals would be cost prohibitive. Maybe in a few years as cities and states change over to digital systems cheaper second hand trunking equipment will be on the market. -- The Radio Page Ham, Police Scanner, Shortwave and more. http://www.kilowatt-radio.org/ |

Trunking is the future of two way radio, it is what the police and public safety community use. Only because that's what The Big Emm and EFJ push them into. I am a communications regulatory and engineering consultant in the public safety communications field, and we have two major clients (big cities in the US) who have told The Big Emm to take their trunked digital 800 MHz system and insert it you-know-where and went back to VHF and UHF analog systems at The Big Emm's expense to avoid a lawsuit on inability to perform per the contract. -- 73 de K2ASP - Phil Kane |
