Changing Frequencies During A Net

OUTLINE – PROCEDURE FOR MOVING A LINN COUNTY ARES NET TO ANOTHER FREQUENCY

  1. When the designated repeater or simplex frequency for a net is or becomes unusable, the NCS will move the net to another repeater or simplex frequency.
    • Normally, steps 2 through 4 should be completed within one minute.
  2. Frequencies should be attempted per the Frequency Plan. If simplex operation becomes necessary, the NCS may turn over control of the net to a stronger or better-located station.
  3. If the net is scheduled to be held on a LCARES’ simplex frequency that is found to be unusable, the net will be moved to the other LCARES simplex frequency. If neither is available, any designated 2m simplex frequency may be used. Some frequencies, however, are designated as primary for other counties or are locally reserved for specific purposes. Please refer to the list below when choosing a frequency.
    Frequency Designation
    146.400 BENTON
    146.415 AVOID: DSTAR repeater input
    146.430
    146.445
    146.460
    146.475
    146.490
    146.505 LINN 1
    146.535
    146.550 JONES
    146.565
    146.580 BUCHANAN
    146.595
    147.405 AVOID: DSTAR repeater output
    147.420
    147.435
    147.450 CEDAR
    147.465 DELAWARE
    147.480 LINN 2
    147.495 JOHNSON
    147.510 AVOID: EIDXA packet node
    147.525 IOWA
    147.540 Common “ragchew,” put this last
    147.555
    147.570
    147.585
  4. The NCS, using as much power and antenna gain and height as necessary and available, and using duplex and/or simplex operation as appears to be required for the problem at hand, will attempt on the original frequency to notify other net participants that the net is moving to the new frequency. Note: In the case of a jammed repeater, there is no point in asking for net participants to “check your mics.” If the problem is a radio stuck in transmit mode (for whatever reason), that radio’s operator will not hear you.
  5. The NCS will begin or continue the net on its new frequency. If the check-in process isn’t complete, the NCS may (to save time) presume stations that checked in on the old frequency have moved to the new one, and will ask for only new check-ins. Exceptions: (1) Stations that had been designated to fill a specific role will be called to ensure he/she is available; (2) where regular roll calls are required, the NCS will call all stations.
  6. The NCS will ask for a volunteer, preferably one with a well-equipped 2m station and, in the case of a jammed repeater (stuck mic, etc.), one close to the repeater’s receive antenna. That person will notify late-comers to the net of the frequency change.
  7. In general, it is better – less confusing – if the net stays on the new frequency should the problem with the original frequency be resolved.
