Ok,
First off, I'm not looking for any frequency inputs or the sort...my questions lies within the actual operation of the NYPD radio system; namely how in the heck two (or more) units are able to transmit at the same time.
My radio expertise extends no further than simple trunked or conventional repeater system, both of which I'm under the general understanding that if one radio on the system is keyed, nobody else (except by rare circumstances) can transmit and get through.
While monitoring the NYPD (usually on SOD), I find central is able to transmit at the same time as other units and I'm hearing both parties on my portable.
In layman's terms, how does this actually work?
