Hearing only one end not the other
Once in a while when i'm listening to the cops i only one end and not the other.What's going on here.
G'day stevesperformance - I find the same thing listening to the wheatbelt police. From what I understand there is a central point (Northam in my case) and several different "branches" to the network so the local coppers (eg Jurien) don't hear what's going on in other parts of the network coverage (for example Cunderdin) Maybe they have the same system there.
If I'm wrong I'm sure someone will take great pleasure in correcting me.

Also, the police radios can be set to a mode that transmits direct car to car and not through the repeater.
Usually called repeater talk around, simplex or local mode. If a car operating on simplex is close to you you'll hear him talking but might not hear the other car. VKI usually can't hear cars when they're on simplex.

The Coppers here in Bunbury use simplex quite often in the CBD between themselves or to the Base, i can usually hear most of their transmissions althought alot noisier, they seem to use simplex when they are on foot walking around town.
Been getting strange full signal hash sounding transmissions here in Bunbury on 469.225 Khz maybe testing digital channel or something ?
Also whats new VKI listing on 506.825 Mhz ?

I reckon you're hearing car to car chat and you're just out of range. VKI don't do split channel stuff like FESA do.stevesperformance wrote:thats what i though but i have tried scan all 64 channels when it happens but still can't heard the other end.

This happened to me last night: I was able to hear VKI on channel 25 talking to a country unit (don't know if it was a vehicle or a station) and I was only able to hear VKI and not the responding unit.
It may be because during quiet periods, a number of country channels with links back to VKI are combined, and the VKI signal goes out on several repeaters simultaneously, but not all the repeaters are activated when a country unit responds.

Listen on channel 55 sometimes, they link it like that quite often. Makes it hard to figure out what channel a vehicle is actually using...Steve wrote: It may be because during quiet periods, a number of country channels with links back to VKI are combined, and the VKI signal goes out on several repeaters simultaneously, but not all the repeaters are activated when a country unit responds.
