Rocket Tracking and Amateur Radio Information

Rocket Tracking Using Radio “Stuff”

As more and more flyers are using trackers, beacons, and radio telemetry, we are publishing this information to help prevent conflicts on the various radio frequencies used.

If you are interested in rocket tracking, but don’t know where to start, please check out this article in the Learn section.

Avionics Frequencies Used by ROC members

If you want your frequency listed here, please use the comment form at the bottom of this page or ROC-chat to let us know what you use. Include frequency, type of system (beacon, GPS tracker, etc.), and your callsign, if applicable. We can’t guarantee there will be no conflicts, but it can’t hurt to let everyone know what you are using.

To help prevent interference from, and to, other spectrum users, there is information near the bottom of this page on how to select an appropriate frequency.

Guidance to Prevent Interference From, and To, other Spectrum Users

Non-Licensed Services (basically not ham radio)

Under development. If you have suggestions post them on ROC-chat or comment below.

Amateur (Ham) Radio

2 Meter Band
Use 145.01, 145.03, 145.05, 145.07, or 145.09. Most of the 2 meter band uses 15 KHz spacing, but these are digital (packet) frequencies still set aside, but with little use.
Beacons should be on an FM simplex frequency including: 146.49, 146.505, 146.55, 146.58, 147.525, or 147.54.

You should AVOID:

  • 144.390, National APRS Frequency
  • 146.52, National Calling Frequency
  • 146.535 (used by ROC on the lakebed)
  • 146.43 (ATV talk back)
  • 146.565 (set aside for Foxhunts and frequently busy on weekends)

1-1/4 Meter Band
APRS rocket trackers should be on 223.46 or 223.48.
For beacons avoid frequencies below 222.13. Use Odd 10KHz buffer frequencies between the FM voice frequencies. California uses 20 KHz spacing with FM voice on even center frequencies.
70 Centimeter Band
APRS should be between 431.00 to 431.60 MHz or 448.94 to 449.98 MHz, even 20KHz spacing. The bandwidth from 434.00MHz to 440.00MHz should be avoided, as this is the input for a nearby Amateur Television repeater,
Beacons should be above 444.15, and use even 10KHz buffer frequencies.
33 Centimeter Band
APRS allocations on 33 Centimeters are on simplex frequencies, 927.500, 927,600, and 927.700.
Beacons must avoid 902.1 weak signal allocation! Should be between 903 and 905 MHz or 925 to 928 MHz.
