CROSS BAND

Which way are they cross banded ??? You transmit on 46.04 and it gets retransmitted on fire 10 on the trunk system, OR, you transmit on fire 10 on the trunk system and the transmission appears on 46.04 ??????

linked trunking

the way it works is it is a one way link you are not broadcasting into the trunking system. the desired talk group is retransmitted to a non trunked freq such as fire 10 to its own uhf freq. it is receive only and
my understanding that only chatter on that talk group is heard. you cannot get into the other side without an authorized id much like a cell phone same principal really

all repeaters are one way

Technically, a one-way device is not a repeater. It is a translator. :)

Simulcasting might or might not involve translators. A simulcast is a mode of operation, not a device.

In a simulcast system ALL the transmitters in the system transmit the same thing on the SAME frequency at the same time. Each transmitters frequency and audio are held to tight tolerances. The received audio to be transmitted can come from remote receiver or repeaters. The audio from each receiver is fed to a comparator (voter) and the best audio from all the sites is then sent to each transmitter. There are several variations of the design but the principle is the same. Hope that helps.

That is true of a single-band short range simulcast system. Simulcasting can be done on any combination of bands or frequencies. The basic definition is that the same traffic is being sent over multiple transmitters at the same time. They don't have to be close in frequency or physical separation.

It's a shame that there aren't more simulcasts of the Westchester trunked system. I enjoy monitoring them via my commercial equipment since the system has such robust audio and signal strength throughout the county and it's a very professional sounding operation. Luckily the departments that cover my home area have links to Fire 10 / Fire 17 etc.
