Repeater Offsets
Occasionally when somebody is programming repeater frequencies into a radio, they will ask what the offset is. Luckily, in Kansas we have a standardized band plan for 2 meters and 70 centimeters. So:
- Repeaters with outputs below 147.000 MHz are negative (-) 600 kHz offset.
- Repeaters with outputs at and above 147.000 MHz are positive (+) 600 kHz offset.
- All 70 centimeter repeaters (in Kansas) have a positive (+) 5 MHz offset. Kansas does not coordinate “upside-down” repeater channels.
How to “quietly monitor” the system (in most cases):
- On our 440 repeaters, you can monitor the repeater traffic without hearing the ID’s and squelch crashes by using your Tone Squelch (CTCSS / PL) decode feature on your radios. This will enable you to hear only voice traffic, plus any top-of-the-hour messages that play over the entire system.
- On most of our 2 meter repeaters, you can use the Tone Squelch feature on your radios to eliminate the squelch crash on your radios. We utilize reverse-burst to quietly mute your receivers. (NOTE: Osborne 147.375 does not encode a PL tone, and Riley 146.685 does not have reverse-burst capability but DOES encode 162.2.
- The hub controllers are programmed to never send hourly announcements after 11pm or before 6:30am.
Why do I hear long bursts of noise on the Minneapolis 147.225 repeater?
The Minneapolis 147.225 repeater is a digital-capable repeater. If you are hearing what sounds like squelch noise on the output, that is a digital voice conversation. To eliminate hearing this noise on your radio, turn on your CTCSS decoder (Tone Squelch) to 162.2hz. You will still hear all analog calls.
