From Tim, WB4GBI:

After being off the air since April 2016, the 146.85 repeater has returned to the air! This was initially made possible when another tower user vacated the site, and left their antenna on the tower. Now, the Sinclair  SD-224 antenna, which was purchased for 146.85, has been installed!


The 146.85 repeater is now located at the WIVK-FM transmitter site, with its sister repeaters- 146.94, 444.300,  927.0625,  as well as the KM4JXA D-Star repeater and the WB4GBI 440.575 DMR repeater. It went back on the air on a temporary antenna in October 2017, but the permanent antenna was installed today (12-19-2017)! 

Please use and enjoy this repeater, whose heritage dates back to 1974!

This is a photo of the inside of the 146.85 repeater cabinet. The power supply is hidden below. The repeater receiver and exciter is in the fold-down compartment,  while the 100 watt RF power amplifier is in the back of the shelf. The control "cards" are in a shelf above receiver/transmitter housing. The Motorola "Maxtrac" transciever is for remote control. The blue box above the "Maxtrac" receiver is the repeater control DTMF decoder. The ID and control relays are on the same shelf as the DTMF decoder. 

146.85 rear

This is a photo of the rear of the repeater. The power supply is at the bottom. Next, there are two fans to keep the power amplifier (PA) cool during long periods of use. The Transmitter PA heatsink is visible above the fans. Aove the heatsink is the GE  MASTR II rear connection panel, then the Motorola Maxtrac control receiver is visible. At the Top of the cabinet is the DTMF control decoder, ID'er, and control relays.

A BRIEF HISTORY OF THE 146.85 REPEATER:

146.85 started off as a VHF Engineering repeater, housed in a dumpster on Cove Mountain, just East of its present site. There was no commercial power on Cove Mountain at the time, and no viable solar panels, so batteries were transported back and forth to the mountaintop site to keep the repeater going.  The original owners of 146.85 were Keith, WA4KJH, and Charlie, WB4TVW. When the FCC began licensing repeaters in the 1970's, the 146.85 repeater was licensed as WR4APM. The 85 repeater served from Cove Mountain until 2013, and during that time a building, tower, and commercial power were installed. Tim (WB4GBI) acquired the repeater and cordination in the fall of 2013. The repeater returned to service with a brand new repeater antenna, new duplexer, and the GE MASTR II rebuilt repeater in April 2015. It served proudly until April of 2016, when the new land owner shut down the tower site and demanded that all radio equipment leave the site.  The repeater was re-located to the WIVK-FM site to join its sister repeaters 146.94,  444.300, 927.0625, 440.575 DMR, 144.94 D-Star. Due to tower crew availability, the return to service was delayed until 2017. 85 returned to the air on a temporary antenna on October 18, 2017, and then was restored to full service on December 19, 2017!
