443.225 K6ARP Downtown Clovis Repeater Coordinated

The Clovis Amateur Radio Pioneers are  pleased to announce the new 443.225 club repeater is now coordinated with the Northern Amateur Radio Relay Council of California (NARCC)

Motorola Quantar analog FM and P25 digital repeater

Location: Clovis Water Tower
Frequency: 443.225 + offset
Modes: Analog FM & P25
CTCSS: 141.3
NAC: $514

.

It is located in downtown Clovis at the water tower facility. The repeater is a Motorola Quantar with the antenna approximately 120 feet above ground level.

Although it was previously used in analog FM, the Motorola Quantar repeater provides mixed mode of analog FM and digital in the form of P25; both of these modes are enabled on the repeater. It is recommended that a tone squelch be engaged in order to avoid hearing the P25 carrier when that mode is used. The tone squelch is 141.3, the same as the TX tone.

The Clovis Amateur Radio Pioneers are  pleased to announce a new club repeater. It is located in downtown Clovis at the water tower facility. The repeater is a Motorola Quantar that was kindly donated by the City of Clovis. In addition to the donation, the facility includes coaxial line and an antenna that is approximately 120 feet above ground level. (Members attending the June club meeting were given an early hint)

Mark Rau, Communications Manager for the City of Clovis, played a key role in providing this new resource for licensed amateur radio operators. In addition, club technical committee member Dr. Michael Moya and club President Rob Mavis assisted with donations of equipment. Their efforts also included time to calibrate, tune and install the new repeater gear.

The donated repeater has a bit of history. It was previously used by the Clovis Police Department as channel #1. It will be enjoyed in the future during community events where licensed amateur radio operators provide communications during walks, runs and rides here in the central valley.

Although it was previously used in analog FM, the Motorola Quantar repeater provides mixed mode of analog FM and digital in the form of P25; both of these modes are enabled on the repeater. It is recommended that a tone squelch be engaged in order to avoid hearing the P25 carrier when that mode is used. The tone squelch is 141.3, the same as the TX tone.

Please note that additional hardware was needed. The funds for that are generated by the C.A.R.P. fireworks stand. Membership dues are appreciated and cover rental fees for the meeting location, but the primary funds to maintain and improve club radio repeaters and equipment comes from the once a year fund raiser. Your assistance working in the booth is needed. Consider spending some time with your fellow members every year at the stand. This year it will be located in the parking lot of the Der Wienerschnitzel on Shaw Ave. in Clovis. The club is providing refreshments and it is a perfect time to also enjoy the camaraderie of your fellow members. Spouses and family can help sell too! (Age 18 and over)

Six Meters: I Repeat Six Meters

Now is the time to enjoy the six meter band. You do not have to wait for a meteor shower, or that special time when the “magic band” comes to life. Six meters is alive and well and waiting for you to crackle some RF energy into the air.

There is a new six meter repeater on Bear Mountain, which is about 20 miles east of Clovis. Allen Hancock (WA6IPZ) has deployed his six meter repeater around 3500 feet ASL. The coverage offered by this elevation allows for handheld 6m radios to get in on the fun, like the Wouxun KG-UV5D or an older Cherokee AH50 6m HT. A Yaesu 817ND can also get in on the 6m FM action. As always, an improved antenna connected to low power radios help.

Allen is no stranger to six meters. He previously deployed a six meter repeater at his home in Hanford and is the most active mobile 6m operator I have encountered. Now with the new elevation, many portable, mobile and home operators in the central valley area can use the band more often. Do not worry too much about a perfect 6m antenna setup. As I noted, a 6m handheld is able to get in. I also reach the repeater using 5W with an off-center fed antenna. A few more watts and your signal will of course improve. Experiment and have fun. Share with others on the repeater what you are using.

A PL tone of 82.5 Hz is required but the repeater does not send the tone out, so avoid tone squelch on the RX and adjust the squelch knob a bit. Six meter FM is not narrow DMR, it is nice and wide, perfect for extended conversations. Setup the split and join in.
