The Ford Amateur Radio League operates 2 club repeaters under the club K8UTT license. All the repeaters are located in the Dearborn, MI area near the Southfield Fwy. All repeaters are open for members and guests to operate.
If there is a problem with any repeater, please contact the following:
Dave Treharne: 734-476-1666
Murray Scott: 248-734-1704
Pat Quinn: 734-729-1993
Club Net: 8pm on Sunday, 2 meter repeater! Please lead the Net if a regular Net Control operator is unavailable. Please click here for the Preamble. Send any updates to the preamble to Dave, N8HKU.
The Net will be conducted in Analog FM mode. After the analog portion, users are welcome to conduct a 2nd net in Yaesu System Fusion digital mode. See Below:
We have an interference problem with the Yaesu Repeater. At night, when the LED lights come on at the hotel, the repeater begins to experience an analog interference pattern on the 2m transmitter/receiver. This only occurs when the 2m repeater is transmitting in analog mode. Digital modes are unaffected. The 220 MHz machine, which is linked, also picks up this interference if the 2m is transmitting. When the repeater controller stops the 2m transmitter from transmitting, the 220 machine stops transmitting the noise as well. We also often hear a hum on the 2m machine, soft or loud. We think this is the ADR unit picking up stray 60Hz noise and creating a 120 Hz hum from it. We are very limited in our ability to access the repeater, so we are not able to do as much experimenting as we would like.
Below is a sound file of the repeater system describing the noise, how it affects communication, and when it does not.
The 2m repeater is fully functional with the Yaesu System Fusion running both Analog FM and C4FM Digital. The repeater is set up in Automatic Mode Select, which means it will choose analog if any transmitter on the system is operating analog, or if it is repeating communication from the 220 MHz machine. The 220MHz machine is functional, running FM Analog only. Note: if the 2M machine is using C4FM digital communication, this will not be repeated on the 220 MHz machine, only analog communication is linked, due to how the Yaesu System Fusion DR-1X repeater is designed.
Recommendation for operating on the 2m repeater: Use the radio's Tone squelch function at 100Hz. We require your radio to transmit 100 Hz to access the repeater. The 2M repeater also sends out 100 Hz on the Output to open the squelch on the radio. With the 2m repeater now capable of sending out digital C4FM signals, any analog radio without the 100 Hz on the squelch output will hear a very loud noise burst whenever the repeater is transmitting in digital. Use of the 100Hz tone squelch will keep your radio silent.
Any radio that is System Fusion capable (Yaesu DR class) will operate on our 2M repeater. We recommend that you use AMS, or Automatic Mode Select, on any radio operating the 2M repeater. This will allow you to transmit and receive in digital mode and in analog mode. Any user who does not have a System Fusion radio will use the repeater in normal analog mode. When they transmit, it will force the repeater and the other users to operate in analog mode as well. That way, everyone can communicate on the repeater.
February 22, 2016: We have installed a Yaesu System Fusion DR-1X repeater as our 2M repeater. This repeater is capable of normal FM Analog communication, plus all of the C4FM operating modes: Digital Narrow, Voice Wide, and Data modes. Digital narrow also communicates station information, such as call sign and location, as the operator has set-up. Information on Yaesu System Fusion can be found at: Yaesu System Fusion document.

Repeater Etiquette: From the January, 2007 FARL Club meeting:
Ford Amateur Radio League
Net Etiquette: Participating in a 2 Meter
Repeater Social Net
Net Date and time: Sunday, 8pm
Traffic can be many things:
· Greetings to the club,
· comment about a prior club event or an upcoming event,
· a general discussion item,
· an announcement. If the announcement is for something such as a for sale item, please follow the following guidelines:
o Make the comment about it brief and introductory
o Recommend only those items that would appeal to amateur radio operators
· Net Control will ask if any operators are interested in responding to a For Sale item. Operators will give their call, and be recognized by Net Control. Then, phone numbers may be exchanged to continue a discussion outside of the amateur radio bands. It is OK per the rules to talk about For Sale items, but details about price, etc, need to be taken off of amateur radio to comply with the No commercial or business use regulation.
The Net may be a good time to announce an intention to attend a swap, organize a breakfast or lunch, etc.
