WA3SFJ Repeater System
A repeater receives on one frequency and retransmits on another, allowing local operators with handhelds and mobile radios to communicate over a wider area than simplex usually permits.
What members should understand
This guide explains the core concepts, practical operating habits, and documentation discipline members need to use the system responsibly.
Two frequencies
A repeater listens on its input and transmits on its output. Your radio must be programmed for the correct offset.
Tone squelch
A CTCSS/PL tone helps prevent unintended access and reduces nuisance key-ups.
Shared system
Listen first, identify clearly, leave pauses, and remember that linked systems may carry audio farther than expected.
Basic repeater signal path
A simplified signal or workflow path members can use to understand the system before asking deeper technical questions.
User radio
Your radio transmits on the repeater input frequency with the correct tone.
Receiver
The repeater receiver hears your signal and passes audio to the controller.
Controller
The controller manages timing, IDs, linking, courtesy tones, and transmitter control.
Transmitter
The repeater retransmits your audio on the output frequency for others to hear.
WA3SFJ repeater access
These are the public operating details carried forward from the club’s WA3SFJ source material. Program your radio carefully and check the club calendar or announcements for any temporary changes.
VHF repeater
Receive: 146.850 MHz
Transmit: 146.250 MHz
Offset: -0.600 MHz
PL tone: 107.2 Hz
UHF repeater

Use normal repeater courtesy: listen first, identify with your callsign, leave room between transmissions, and keep conversations clear for all operators.
GMRS repeater information
This GMRS information is current user-supplied data for the site, not old WA3SFJ website source material. GMRS is a separate FCC radio service from amateur radio, so operators must follow the applicable GMRS rules and license requirements.
GMRS repeater
Frequencies: 462.700 Tx / 467.700 RX
PL tone: 107.2 Hz
Callsign: WQYM714
Keep services separate
Amateur-radio repeaters use amateur licenses and Part 97 operating rules. GMRS repeaters use GMRS licensing and rules. Do not assume the same radio, call sign, or operating privilege applies to both services.
What to check before changing anything
These are safe learning and documentation steps, not permission to modify repeater, tower, electrical, or club infrastructure without approval.
Verify first
Confirm frequency, offset, tone, and call sign before sharing settings or programming radios.
Listen locally
Check for distorted, weak, noisy, or clipped audio before assuming a coverage problem.
Record location
Coverage reports are useful only when the location, radio, antenna, and conditions are recorded.
Authoritative learning sources
Learn more through trusted amateur-radio references and official service resources.
FCC Part 97
Amateur Radio Service rules, station responsibilities, and operating standards.
Program and test carefully
Use the quick-start settings, listen first, identify properly, and ask for help if offset, tone, linked access, or GMRS-versus-amateur settings are unclear.
