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.

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.

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.

We welcome your help in testing this new repeater system and thank you in advance for your participation and patience during the testing period.
