Basic Repeater Guide
KK7DFM • KK7DFL

Repeaters extend the range of your radio by receiving on one frequency and transmitting on another. The Whiskey 7 network runs two repeaters: KK7DFM and KK7DFL.

Amateur radio only — not CB, GMRS, or any other service. You need a valid amateur radio license and proper equipment to operate through these repeaters.

Repeater basics

Amateur radio repeaters are typically separated by an offset — the difference between the receive and transmit frequencies. A standard offset is plus or minus 5 MHz depending on the band.

Simplex vs Repeater

• Simplex: transmit and receive on the same frequency. Good for short-range, local conversations.
• Repeater: transmit on one frequency, repeater listens and re-transmits on a separate frequency. Great for extended-range coverage.

KK7DFM & KK7DFL info

These are the two repeaters on the Whiskey 7 network. Program them into your radio with the correct offset and tone.

• Callsign: KK7DFM
• Callsign: KK7DFL
• Offset: (check the repeater details page for exact offset)
• CTCSS / DCS tone: (check repeater details for tone)

Basic procedure

1. Listen first — make sure the repeater is not in use.
2. Key your mic and give your call sign: “KK7DFM, this is [your callsign] listening.”
3. Pause for a response.
4. Identify at the end of your transmission and at least every 10 minutes during a QSO.
5. When done, say “KK7DFM clear” or simply “[your callsign] clear”.

Setting up your radio

1. Enter the repeater’s receive frequency in your radio’s VFO.
2. Set the transmit offset (positive or negative) and the offset direction.
3. Set the CTCSS or DCS tone to the one required by the repeater.
4. Save the channel with a descriptive name (e.g., “KK7DFM”).
5. Test by transmitting and checking that you can hear the repeater’s courtesy tone.

Etiquette tips

• Keep transmissions short and to the point.
• Wait a few seconds after the courtesy tone before keying up.
• Use plain language — avoid Q-codes unless everyone on the net knows them.
• If you hear an emergency, clear the frequency immediately.
