I am starting this thread to discuss the club’s repeaters and such.
Please feel free to comment and/or ask questions.
As I may not see this forum frequently please call or text me if there are more urgent matters regarding the club’s repeaters.

An RF amplifier was added to the 146.76 repeater which raised the power out of the duplexer and into the coax from 12.5 watts to 55 watts.
Receiver sensitivity is not changed however you should be able to hear the repeater further out.
Please let us know if you notice a difference.

Not sure if this info can be shared but, can the repeater hardware technical info be shared… type , model, output power, etc.? Also how high is the antenna in elevation including tower height, type of antenna being used………………. backup systems in-place…………….
A Digipeater/IGATE has been added to the Atlas site by combining into the existing 146.76 antenna. This will provide good fill-in between Paris and the Sulphur Springs – Greenville area. This is operating on the standard 144.39 frequency.
By having the Digipeater/IGATE at the repeater site we should have full coverage of the Tour de Paris course and will be able to utilize the capabilities of APRS in the future.
Turn your APRS on as you drive around and see how it works for you!

The repeater is the Yaesu in the picture. You can look up the details on their website. The repeater will transmit at 50 watts but not continuous duty, at the rated continuous duty medium power output we only get 12.5 watts after duplexer losses. The external amplifier gets us back to 55 watts out.
The tower is 220′ high and we are using DB-224 and DB-420 antennas that are top mounted.
For now we have a small UPS and the site has a generator for backup.
I have been using the APRS function a lot more since this was added. It seems to be working very well. You can look for me as I drive around, although, I’m not usually doing anything very exciting. Mostly, home and work.
RF amplifiers have now been added to both the 146.760 VHF and 444.500 UHF club repeaters at Atlas. These are genuine continuous duty repeater amplifiers and each is capable of 100 watts output. After duplexer/combiner losses we get about 60 watts into the antenna feedlines, before we had about 10 watts out.
This should improve how you hear the repeaters however it does not improve the repeaters’ receive sensitivity.
