The KA1RCI Repeater Network

927.6125 / 902.6125 with PL 131.8 - Established 2004

Lincoln - Rhode Island

2004 marked a great deal of changes to the repeater network. Major upgrades to the 223.960 and 449.325 system including a new powerful FF-800 controller along with a move to a prime site with 350 foot towers in Johnston, RI. The move to Johnston left a few vacant repeater antennas on the 80 foot Lincoln tower so I decided to build some new 440 and 900 MHz repeaters to warm up those antennas!

Here are several photos of the various stages of the temporary repeaters during the construction phase.

The three photos above show show 447.775 online using a pair of Kenwood TM-V7A radios while I was building the permanent repeater RF units and having the new UHF duplexer tuned for my frequency.

The four photos above show the 100 watt VHF duplexer running the 146.460 / 147.460 repeater while the large duplexer is being tuned for the new input frequency. The other photos show 146.460 and 927.500 on the air using a pair of Kenwood TM-241A's and a set of Motorola GTX radios. You can also see the new 447.775 duplexer in the bottom and the small blue rack tuned and ready for the new UHF RF units. The 223.960 and 449.325 rack is in the back ground also getting an upgrade with a new link radio and the new FF-800 controller.

The replacement transmitter for the 447.775 repeater finally arrived after weeks of waiting and I was able to pull together all the components for the 146.460 / 447.775 / 927.500 Repeaters. In these three photos the repeaters are "on air" with a combiner allowing both the VHF and UHF repeaters to share the small antenna for testing. The 900 MHz repeater is still only running on a small mobile antenna while I wait for the final frequency pair so I can have the duplexer tuned.

I was finally given the the frequency pair 927.6125 / 902.6125 and worked with Doug Blade who is a legend in the 902 MHz groups to convert my Motorola radios into the repeaters transmitter and receiver.

Along with the 146.460 and 447.775 repeater I rebuild all this hardware into a larger cabinet that would accommodate all the hardware from these three repeaters.
