Pawtucket's UHF system is horrible. It is antiquated, poorly maintained and there is no plan is in place for upgrade of any of the equipment. It sounds crappy, even IN the city. Pawtucket FD should have migrated to RISCON years ago but the city leaders decided to build a soccer stadium instead.....
Here is some relevant info:
Fact: PFD has 2 transmitter sites. 1 each for channels 1 and 2. 1 at 175 Broad St, 1 at 214 Roosevelt Ave., about 45 watts EIRP transmitter power.
Fact: The 3 other " UHF sites" in the city are receiver sites only. They DO NOT transmit (Grotto Ave incinerator, FD Stations 4 and 6)
Fact: The recently reinstalled receiver is on a lower structure and does not cover a large portion of the city where it is located.
RISCON provides more reliable coverage in the city than the current 20 year old city UHF system does.
And here's why:
Pawtucket is covered by no less than 5 RISCON sites, including one at 175 Broad St (sound familiar?)
Those sites have an transmitter EIRP between 175-300 watts.
Those sites transmit simultaneously (at the same time) to provide better coverage, due to the fact that the RF energy is entering the city from multiple directions. This drastically reduces the issues of buildings, terrain or other blockages affecting how well the radios transmit to and receive the system.
mrsvensven, spend some time learning about how digital trunking works and maybe invest in an scanner that can monitor RISCON so you can hear the difference.
