W9RH Repeater
The MRAC owns and operates a repeater on 145.390MHz, -600KHz offset.
To access the repeater you will need to encode a CTCSS (PL) of 127.3Hz
The repeater is located on the channel 18/10/36 tower where the receive antenna is at the 730 foot mark and the transmit antenna at 630 feet. The antennas are fed with 2-1/4 inch hard-line.
Repeater: GE Master commercial repeater
Power Output: Approximately 15 watts
TX Antenna: Decibel® DB224e 6 db gain antenna
RX Antenna: Decibel® DB224e 6 db gain antenna
ERP: Approximately 71 watts
Controller: S-Com 7k controller including a
DAD, digital audio delay (produces a clean squelch tail)

On March 16, 2014, the Milwaukee Area Digital Operators Group (MADOG) and the Milwaukee Radio Amateurs' Club (MRAC) partnered together to demo the Yaesu “System Fusion” repeater.
“System Fusion” is Yaesu’s version of digital communications, offering repeater owners the ability to provide a repeater that can be used by both analog and digital users separately. It has the ability to automatically switch modes depending on the type of signal received. Additionally, there is another repeater mode available in which digital users can talk into the repeater and transmit as analog for all users to hear.
MADOG and MRAC have temporally replaced the 145.390 W9RH repeater with the “System Fusion” repeater. Testing of the system will continue over the next several weeks leading up to Amateur Electronic Supply's Superfest on April 5th, 2014. Analog users will hear what sounds like static. This noise is the digital signal being transmitted by the repeater. We recommend users program a tone squelch of 127.3Hz into their radios. Over the next several weeks, we also plan on incorporating the current MRAC controller.
We need your help testing the system. We are required to submit reports at the 1-week, 1-month, and 3-month intervals after operation is started.
Please provide us with your feedback about the repeater’s operation to ka9wxn@gmail.com. Is the analog range the same as before? How is the audio quality? Have you noticed any problems with the repeater?
We welcome your help in testing this new repeater system, and thank you in advance for your participation and patience during the testing period.
