New home for the 146.76 repeater

A new home has been found for the 146.76 repeater. Nemours Chidrens Specialty Clinic in downtown Jacksonville has agreed to host the repeater.   The mounting location for the antenna will be on the roof of the building at about 160feet.    Below is a map of the estimated coverage.   Installation is expected to be complete by the end of November.

NOTE: This map is only an estimate of coverage.
Actual coverage can vary greatly depending on equipment used and atmospheric conditions. Green indicates typical hand held coverage. Yellow indicates typical mobile coverage.

The US Air Force reveals radical plan to ‘bomb the sky’ to improve radio reception

  • CubeSats carrying ionized gas could create radio-reflecting plasma
  • This would occur in the ionosphere, which becomes denser at night
  • Bouncing signals between ground and ionosphere can improve range

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!
