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

WHAT IS DSTAR?
This article is from Wikipedia, the free encyclopedia.
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.
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,
is a photo of the KM4JXA D-Star repeater in its new home. 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.
