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!

On 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!

The 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!

 The 53.150 repeater is home to the Radio Amateur Club of Knoxville (RACK) Sunday Night six meter net! Please join us on Sunday Nights at 9:00 PM local time. Jack, K4EPC, is your net control. After the FM session on the repeater, there will be a SSB and AM portion on 50.200 Mhz and 50.4 Mhz respectively. 

Enjoy!
