The 53.150 MHz repeater now has full emergency power! As of July 2017, a new 8
KW generator with a 250 gallon propane tank has been installed at the
repeater site and is fully operational! Based on fuel capacity and
consumption, there is enough fuel to completely power the site for
several days. This insures the repeaters will be available for users
and emcomm/auxcomm groups throughout any event that is needed.
Equipment has also been installed to notify in the event of a power
failure. Pictures to follow soon!

OPERATIONAL STATUS: ON THE AIR!
Wednesday, May 15, 2013, Tim Montgomery (KE4OTZ) and I went to the 146.625
repeater site near Look Rock. The 53.15
repeater had already been delivered to the site earlier, along
with the new antenna and feedline.
We just needed a day that the weather cooperated, and
that Tim and I were both available. After a long journey from
its purchase in Fall 2007, today was the day- we were finally able to get
it on the air!
repeater is a Motorola Micor, with a homebrew
controller. The ID is a RACOM unit which came from commercial service. At
present it is ID'ing every 10 minutes. I intend
to have it ID when keyed up (like my other repeaters) soon. The repeater
(right photo) and duplexer (below) are mostly the same as they were when
Sam Kirby (WB4HAP-SK) had the repeater on English Mountain. The Antenna (left photo)
is a Sinclair single-bay side mounted "trombone" antenna which is
mounted right under 146.625's antenna at 120 feet on the tower. It is
fed with new Andrew 1/2" heliax. The
repeater is operating at 50 watts duplex power. There is no tone
required to access the repeater. I hope to hear you on 53.15 soon!
A HUGE "Thank you" to Tim,
KE4OTZ, for his work on installing the 53.15 repeater antenna on the tower!
