Boston Mass area if there were patches from the simplex MetroFire FG / fireground UHF channels to the State TRS (comirs) - the patches would have to be special non-interferring patches - right?
the patches would have to be set up such that whenever there was any traffic on the UHF side - then no one on the TRS side could transmit via the patch and probably vice versa also - whenever anyone was transmitting on the TRS side of the patch - no one could transmit on the UHF side - no - thats not correct the bottom line problem with patching from a repeater channel to a simplex channel - seems to be that - the units on the repeater have an inherent priority / superiority over the simplex units - how can we explain this? if there is a stuck mike on the TRS side - and the patch is hard wired to rebroadcast ALL traffic - then the simplex channel becomes essentially unusable - unless the patch is turned off if there is a stuck mike on the UHF side - and the patch is hard wired to rebroadcast all traffic - the units on the TRS side can technically still transmit - even though they would need to "talk" over the noise from the UHF side maybe a better explanation is - if the patch is on - and someone accidentally hits their xmit button on the UHF side - they dont totally dont prevent from someone transmitting on the TRS side - if someone accidentally hits their xmit button on the TRS side, they throw a 100 watt signal onto the 5 watt simplex channel - there is a major mismatch there - but the 100 watt signal is coming from a distance (its typically not at the fire scene) there might be a way around this - have a UHF receiver or transportable UHF repeater brought to the incident scene - the UHF receiver picks up the UHF simplex traffic and relays it into the TRS via some means - this would level the playing field between the TRS radios and the UHF radios - in a manner of speaking -- You received this message because you are subscribed to the Google Groups "massfire" group.
