K2CC Emergency Communications

K2CC Emergency Frequencies

Repeater (Primary)

The analog K2CC repeater is located at Clarkson University and should be used for primary K2CC emergency communications. It may be reached at: fcaqwse

K2CC Repeater Quick Reference
  • K2CC 2m Repeater Frequency: 146.895 MHz FM
  • Offset: -0.600 MHz (standard negative) offset for input
  • PL tone: 151.4 Hz for input

Radio-to-radio Simplex (Secondary)

In the event our repeater is down, K2CC members can meet on the K2CC Club Frequency. (In the event that the K2CC Club Frequency cannot be used due to interference or others already using it, the Backup Club Frequency is used.) These simplex club meeting frequencies have no offset and require no PL tone for use.

K2CC Simplex Quick Reference
  • K2CC Club Frequency: 146.460 MHz FM simplex
  • Backup Club Frequency: 147.470 MHz FM simplex

Remember that on the radio bands provisioned for amateur use, it is not possible for any individual or group to own exclusive rights to any frequency. First priority goes to purposes that have been officially coordinated by a Frequency Coordinator entity (repeaters on their appropriate frequencies, and the use of those repeaters on those frequencies), and second priority goes to those already engaged in a conversation on a particular frequency. Additionally, operators should always yield airway usage to "emergency" and "priority" communications.

Preparedness Recommendations

Minimum Preparedness

For emergency preparedness, K2CC recommends that members minimally:

  • KEEP PORTABLE RADIOS AND BACKUP POWER SOURCES FULLY CHARGED (good when you least expect a disaster and especially good when you expect one)
  • KEEP A PAPER PRINTOUT OF USEFUL FREQUENCIES and PROCEDURES (print this document to keep in your apartment/dorm and vehicle)

The following two subsections address additional preparedness recommendations.

Dorm and Apartment

It is also a good idea to keep in your dorm or apartment enough non-perishable food (if canned, have a can opener) and water handy for your needs for several days, along with extra blankets and warm clothing. Be sure to have a good jacket (warm and watertight), boots, a hat, and gloves in case of inclement weather.


Always check weather forecasts before traveling, and be sure to include several points along your trip in your forecast lookup (i.e. Potsdam, Watertown, Pulaski, Central Square, Syracuse) since some places (i.e. the Tug Hill Region between Watertown and Central Square, and the Cortland area between Syracuse and Binghamton) can have entirely different forecasts than your starting and ending points (i.e. Potsdam and Syracuse). In your vehicle, be minimally prepared with a vehicle charger for your cellular telephone, a few unopened bottles of water, a working flashlight, a jacket, a hat, gloves, boots, extra warm clothing, and a blanket.

Know regions that you will pass through on your trip that have poor or no cellular telephone coverage (i.e. portions of 11-N and 56-S), have a list of common calling frequencies and area repeater frequencies kept in your vehicle, and familiarize yourself with the frequencies, offsets, and PL tones of prominent, well-used repeaters that you will be passing by along your trip. Obey all National Weather Service and area emergency service personnel's requests for not traveling or for limiting travel for emergency use only.

Outside Emergency Communications

National Amateur Frequencies

Quick Reference

Repeaters are probably your best bet at reaching someone with a mobile or portable radio, but these Quick Reference calling and operation frequencies at many times might also be good bets.

Primary Simplex Frequencies
  • 2m FM Call Frequency*: 146.520 MHz FM simplex (PRIMARILY MONITORED)
  • 70cm FM National Simplex Frequency*: 446.000 MHz FM simplex
  • 70cm St. Lawrence County RACES/ARES: 446.050 MHz FM simplex, 446.175 MHz FM simplex
  • 6m FM Call Frequency*: 52.525 MHz FM simplex
  • 1.25m FM Call Frequency*: 223.5 MHz FM simplex
  • 23cm National Simplex Call Frequency*: 1294.5 MHz FM simplex
Emergency Simplex Operation

[*] These frequencies are monitored (especially 146.520 MHz) at least between the hours of 07:00-07:05, 10:00-10:05, 13:00-13:05, and 16:00-16:05, but may be monitored at the top of every hour or at other times as well.

For "priority" or "emergency" transmission, begin with 10 seconds of transmitting DTMF "0" (known as "Long Tone Zero").

For routine transmission (when simply monitoring) wait until four minutes after the hour for periodic ID.
