146.760 MHz repeater comes to life…  Saturday, April 23rd, 2016, Ben Bramlett K7BEN, (our dauntless Technical Committee Chairman) and Justin Ellis, Sr., KK4GPY, President of Jacksonville RANGE Association, Inc. and technical committee member extraordinaire, worked for nine hours at the Twin Towers near I-95 and Golfair on the north side accomplishing much!  146.760 MHz is on the air transmitting with about 160 watts of power to a high gain VHF antenna and is receiving, via remote pickup, 146.160 MHz from our Dames point site.

The Orange Park remote site has yet to be tied into the system through the LDG RVS-8 8 channel voter system which apparently suffered failure of a TL084 quad op amp chip and/or failure of a 3240 dual op amp chip so that it would pass no audio at all for either channel 1 (Dames Point) or channel 2 (Orange Park) through to the CAT-1000 controller board.

Another member of the Technical Committee, Jack Driskell, KB4B, has suggested that the failed chips be replaced by corresponding chips that are used for RVS-8 voter channels 7 and 8 which are not currently in use.  As all chips on the RVS-8 PCB are in sockets making the changes will not be too difficult.

New 6 meter repeater under construction

We have taken out of service the 40 year old Motorola 6 meter FM repeater rack of equipment on 53.330/52.330 MHz at the Twin Towers on the north side.  The old unit had many problems.  The new repeater is being built from two Maratrac Motorola transceivers and, although capable of 110 watts output, the transmit unit will be programmed down to about 50 watts due to the extreme heat conditions of the environment.  As no one in the area has the necessary RIB (radio interface box) tool to interface between the programming computer and the radios, we are building one from a kit furnished by Richard Miller, K4IFG, on the west side.

The Maratracs are currently programmed for our frequency and access CTCSS (continuous tone coded squelch system) tones of 127.3 MHz both on encode and on decode.  The otne access will keep down the interference from out of the area signals especially during band openings.   The tones chosen are in accordance with the tones used by the vast majority of analog FM repeaters in the Florida Crown District area.

This will be the fifth and last RANGE repeater to be brought back on the air since we lost our primary site in 2015.

New Yaesu Fusion Repeater

W4RNG 444.675 Fusion Repeater

About a moth ago the Jacksonville Range Association installed one of our two new Yaesu fusion repeaters.   The new repeater will continue operation on our existing UHF frequency of 444.675.  The old repeater will remain on location as a backup.  Yaesu Fusion technology allows us to continue to use our existing analog radios while allowing owners of fusion radios to take advantage of the enhanced audio and data that the digital system provides.  For more information on Yaesu Fusion, visit http://www.systemfusioninfo.com/  Information on all of the Jacksonville Range Association’s repeaters, visit our repeaters page.

Echolink is back on the 147.315mhz repeater

The Echolink setup that was previously on the 146.76 repeater is now on the 147.315 repeater.   We are working on cleaning up the interface and fine tuning audio levels.   It may be intermittently offline until it gets to its permanent home on April 2nd.  Please feel free to download Echolink and connect to us on node #  504177

When is damaged coax a good thing?

When it get’s donated to RANGE.  A local communications company ordered a 100+ foot run of 7/8 inch RFS Cellflex cable.   It was kinked during the process of putting it on the spool.  We unwound the cable and removed the damaged area leaving us with about a 48 foot run and 82 foot run of cable.   This donation is worth over $500 and will come in handy as we continue to expand coverage of the .76 repeater and upgrade the UHF repeater.   Thank you to our anonymous donor!
