The current ICARC Membership Roster is available here.
Membership in the Iowa City Amateur Radio Club is open to all who have an interest in amateur radio. An FCC license is not required for membership, but if you are not currently licensed, we will help you pass the tests and become licensed if you so desire. Also, membership in the ARRL is highly recommended, but is not required. To join, please print and fill out the Membership Application and mail it to the address on the form, along with a check for your dues.
(Note: If you have trouble printing the Membership Application form, an Adobe Acrobat PDF version is available here.)
Payment of dues is required for membership. The ICARC dues schedule follows (all amounts are per calendar year, prorated for part-year membership for new members only):
|Senior (age 75 and up)||$10.00|
|Senior Family (age 75 and up)||$15.00|
Membership dues are the sole source of income for the Iowa City Amateur Radio Club, and support all activities of the club, including the WØJV repeater (a very expensive undertaking), the Field Day potluck dinner, programs and refreshments for the regular meetings, and other activities as authorized by vote of the memberhsip.
|WØJV Trustee||John Kauble|
The Iowa City Amateur Radio Club (ICARC) has been in existence since at least 1933, when it was first affiliated with the American Radio Relay League (ARRL), the national association for Amateur Radio. The club callsign, WØJV, belonged to a long-time club member, George Carson, who was a Physics Professor at the University of Iowa. The club obtained it as a memorial callsign following his death. The callsign is used on the club’s two-meter repeater on 146.25/146.85 MHz, as well as for various club events, such as the annual Field Day exercise.
Minutes of past meetings are available on the "ICARC Meeting Minutes Index" page.
In January 2007, KØGH and NØRXD installed a new controller unit and a new commercial repeater running approximately 45 watts. The previous repeater is being kept as a back up.
The repeater requires a 192.8 Hz CTCSS tone for access. This means that when you transmit on the repeater's input frequency, your transceiver adds a very precise audio tone (192.8 Hz) at a very low level superimosed on the transmitter output along with the microphone audio. The repeater must sense that tone on the received signal to open the squelch. A circuit called a Carrier Operated Switch senses the squelch opening, which tells the repeater that there is a carrier on the input. The controller keys the transmitter, thereby repeating the signal from the input frequency. (The tone frequency used on the WØJV repeater (192.8 Hz) follows the recommendation of the Iowa Repeater Council for our area.)
The Repeater: Top: Kenwood repeater.
Bottom: The Duplexer (gold cylinders) - This unit makes it possible to transmit and receive at the same time on a single antenna!
The Antenna: The tower is 300' tall. The WØJV antenna is at 150' and is marked with an arrow.
The Johnson County Sunday Evening Net is primarily a "social" net, which meets at 7:30 PM every Sunday evening on the WØJV repeater on 146.85 MHz, which requires a 192.8 Hz PL tone. Although this is an informal net, proper directed net procedures are followed.
In case of malfunction of the Iowa City repeater, the first alternate net frequency is the Coralville repeater on 147.15 MHz, which also requires a 192.8 Hz PL tone. In case neither repeater is functional, the net will meet on the national simplex frequency, 146.52 Mhz.
Net control responsibilities may be rotated monthly through volunteers from area amateur radio operators. If you would like to volunteer, please do so at a regular monthly meeting of the ICARC, or contact Jeff, KIØJP. Information exchanged includes ham radio-related news, such as meeting notices or other club activities, VE session announcements, hamfest announcements and equipment for sale. Please check in whenever you can.
(For Net Control Stations: A suggested net control script and roll call is available here. You can download this same information in PDF format by right-clicking this link and choosing "Save Target as...". The roll call sheet lists callsign, name and QTH for those who frequently check in, and has additional columns to record check-ins and traffic, if any.
The Skywarn® Net is an ad hoc net which may be activated by request of the Johnson County Emergency Management Agency, the National Weather Service or any amateur radio operator when severe weather is identified in any part of Johnson County by the National Weather Service. Weather sirens sounding are a valid trigger for opening the net. The net meets on the WØJV repeater on 146.85 MHz, which requires a 192.8 Hz tone. Trained weather spotters from various areas of the county may observe weather conditions and report their observations to net control.
Please see the Skywarn® Net Operations page for more information.
The Iowa City Amateur Radio Club is neither officially involved nor responsible for any such operations.
