Above are those who make the 470ARG net , they are the base of the Facebook Page and the Net, along with our repeater owner and pictures of the repeater , tower, and view of the mountain which the 145.470 sits upon. at 3550 FT !! Covering Several States from one repeater !
The 145.47 was Tim's first repeater, which went on the air for the first time on September 17, 1981. The picture you see here is the actual 145.47 repeater when it was located at Tim's home, before it went to its first location atop View Park Hill (the present 145.17 site) in November 1981. The equipment you see is General Electric "Progress Line" tube -type equipment. The repeater was a "prog-line" receiver and transmitter with a home-brew control board and diode-matrix ID'er. From View Park, it has been located on House Mountain, Bluff Mountain (near where 146.94 is now), and "Top-of the-World" (the present 146.625 site). After the GE progress line equipment was retired, the 145.47 repeater sported a GE Master Pro solid state receiver and a Motorola VHF exciter/PA combination. In 2005, Tim took the repeater off the now 146.625 site and completely rebuilt the repeater, using a factory-stock GE Mastr II repeater that you see in the above pictures. Here's a link to the NEW 145.47 history page! Click here.
After the rebuild.... and after receiving the SERA coordination, Tim was finally able to relocate the 145.470 machine to its long awaited home on top of Cross Mountain in January 2007. For a long time, it has been obvious that this location was perfect for a repeater. As a matter of fact, Tim originally did attempt to locate a machine there back in th
When this repeater was first put into service at this location, it was hoped that it would cover an area just to the north of Knoxville to up near the state line... however... that was not to be the case. As it turns out, we were pleasantly surprised that this machine has far exceeded those boundaries!
In reality... this repeater covers a wide and rugged area of the Southeastern United States! Many regular users of this machine do so routinely from Tennessee, North Carolina and Kentucky!
Although many East Tennessee hams use this machine every day, we have been known to make contacts in Virginia... Georgia and even parts of Ohio!
