    • Bob Renn (KF7JPJ) would like to the membership approve the Treasurer's report at each meeting.
      • It was moved, seconded and approved to accept the Treasurer's report.
  3. Repeater Report
    • 70cm
      • Tim Bailey (AD7IW) has sent a communication from the Brundage Mountain Ski Patrol that is requesting that the 70cm repeater and antenna be removed from Brundage Mountain. Tim sent the following notice to CIARC:

        At our last Ski Patrol meeting the CIARC Brundage Repeater was brought up, and a request was made to have it removed. It sounds like to me this may be due to the issues with the repeater and more importantly the antenna. Since I am a member of the Payette Lakes Ski Patrol and the CIARC, I have been trying not to get to involved with the repeater on Brundage, if possible, so to avoid any issues with me being a member of both groups, but the Ski Patrol did ask me to pass this information/request onto the CIARC. I do not have much more information than this, but if you should want additional information, please let me know and I will send you contact information, if needed.

        If you have any questions, please let me know.


        Tim Bailey, Payette Lakes Ski Patrol - Brundage Mountain Central Idaho Amateur Radio Club - AD7IW

      • A response needs to be given to the Ski Patrol to indicate when we can have the equipment removed.
    • 2-meters
      • The 2-meter receiver is exhibiting a crackling noise intermittently. This noise is not evident on the transmitter. The noise may be due to snow and ice incursion in the antenna system and may be evident only on the receiver due to the low signal levels when compared to the transmitter.
      • The transmitter is protected by the isolator from any antenna failure so there is no risk of additional equipment failure.
      • On-site inspection is needed.
    • 33cm Link Back-bone
      • The 33cm link receiver is also exhibiting decreased performance. Snow and ice incursion is suspected. It may be that there is damage to the antenna.
      • On-site inspection is needed.
    • Repeater Network Extensibility - 3RARC
      • Lenard Crogh (W7HXU), Larry Stokes (N7IBC) and Ray Montagne (W7CIA) met with Fred Carey (KF7QVB), Stan Lewis (KK7STL) and Ken Tuning (KT7KEN) of the Three Rivers Amateur Radio Club (3RARC) to discuss the possibility of installing a repeater system in the Riggins area and linking that repeater both to the CIARC repeater network and to the 3RARC repeater.
        • All Fresnel link path studies assume that the link hub is located at the No Business repeater site.
        • Projected coverage for a 30 watt 2-meter repeater operating at the Riggins site is 50,018 km2 or 19,312 miles2, with excellent coverage along the highway 95 corridor from New Meadows to Grangeville.
        • Projected coverage for a 30 watt 70cm repeater operating at the Riggins site is 13,494 km2 or 5,210 miles2, with intermittent coverage along the highway 95 corridor from New Meadows to Grangeville.
        • The Riggins repeater site has a viable Fresnel link path over 33cm to the No Business repeater site, with a projected signal level of -84 dBm (note that signals better than -115 dBm are considered to be adequate for communications).
        • The Riggins repeater site has a viable Fresnel link path over 224 MHz to the KK3ARC 3RARC repeater, located at Kooskia, with a projected signal strength of -103 dBm.
      • Site studies for both 2-meters and 70cm have been made. Fresnel link path studies have also been made. All studies show excellent possibilites for a 2-meter repeater system with linking to CIARC and 3RARC.
      • Fred Carey (KF7QVB) is working to procure access to the repeater site.
      • Once access to the repeater site has been secured, Ray Montagne (W7CIA) will help the 3RARC group obtain a repeater coordination. The preferred band will be 2-meters with 70cm acting as the back-up band.
      • Both clubs will then need to determine their level of participation in procuring equipment and building the repeater.
        • A Kenwood TK-981 33cm half-duplex link radio and antenna will be donated by Ray Montagne (W7CIA).
        • Should a 2-meter frequency coordination be available, Ken Stroube (WA6YOP) has a 100-watt Motorola MSF5000 repeater (no controller, no duplexer) available for $100 (including programming of the frequency).
        • Other needed components:
          • Duplexer
          • Isolator
          • Repeater Controller (3-ports minimum)
          • Feed-line
          • Antenna (D.C. ground preferred - may require directional north & south radiation pattern for 2-meter frequency coordination).
          • Link radio and antenna for linking to KK3ARC 3RARC repeater (band TBD).
          • Power Supply
  4. NET Report
    • The weekly 2-meter net, normally held on Wednesday evenings, will be postponed until the 2-meter repeater receiver noise issue is resolved.
  5. Bob Renn (KF7JPJ) and Lenard Crogh (W7HXU) will generate a receipt for Martin Tushkowski (KE7KQE) for the equipment that Martin has purchased from the club.
  6. Bob Renn (KF7JPJ) has deferred calling other amateurs who possess Phoenix radios until this month.
