OPERATIONAL STATUS:

ON THE AIR, WITH A BRAND NEW ANTENNA AND FEED LINE! 


From Tim, WB4GBI: After what seems like a constant struggle since placing the repeater on the air in September 2015, the KM4JXA repeater is on the air and working as it should! When the repeater went on the air, there were internet connectivity issues. Then, the DB-222 antenna failed, as well as the LMR-400 line that was being used at the time. The repeater was shut down on March 25, 2017. On March 31, 2018, Stephen, K1LNX and myself went to the site to start the process of trying to restore the repeater to useful service. I purchased a static IP from the internet provider to eliminate the VPN tunnel and its associated latency issues.  Stephen and I re-programmed the repeater and router, in anticipation of the new antenna arrival. On May 3, 2018, the new SD-222 repeater antenna was installed, and on May 8th, the repeater was returned to service! If you have a D-Star radio, please let me know how it's working for you. Thank you! 73 de Tim WB4GBI  


The KM4JXA D-STAR repeater is located on Bluff Mountain (Greentop) in Sevier County, Tennessee. It shares the site with the WB4GBI 146.940, 146.850, 444.300, 927.0625, and the 440.575 DMR repeater. 

WHAT IS DSTAR?  

This article is from Wikipedia, the free encyclopedia.

The KM4JXA callsign is licensed to the East Tennessee Digital Radio Group, trustee WB4GBI. Due to the necessity to have a separate callsign for the D-Star repeater, the ETDRG was formed.

The KM4JXA D-Star repeater operates on a non 600 Khz offset frequency of 147.44 receive (mobile transmit), 144.94 transmit (mobile receive). This combination of frequencies is now specifically assigned for digital repeate usage by SERA, of which KM4JXA/WB4GBI is a member. The KM4JXA repeater is also now included in database downloads from the D-Star information website, www.dstarinfo.com

The black cabinet in the foreground houses the repeater controller, 2 meter D-Star repeater itself, the six-cavity VHF duplexer, power supply, and the Linux-based computer server necessary for internet operation and access. The three tuned cavities for receiver filtering are to the left of the D-Star cabinet.
