Congratulations Go ahead and make a call and see if someone will come back to you.However, in this article well talk about some basic troubleshooting steps to help diagnose the problem.For this article, I am assuming that your first rig is a handheld vhfuhf transceiver but the general approach will work with mobile or base transceivers, too.The key things we have to pay attention to are: F requency, O ffset and T one ( FOT ).
To access a repeater you need to have its Frequency entered into your radio, have its transmit Offset set correctly and have the right CTCSS Tone turned on. You might not need to check all of these things in that exact order but it is a good way to approach the problem. Using the programming software (and suitable cable) for your radio can be a big help. The actual key strokes or knob turns will depend on the particular model of radio so consult your operating manual. The frequency you enter is the repeater transmit frequency which will be your receive frequency. Repeaters are always referred to by their transmit frequency, which can be found in an online or printed repeater directory. This is the difference in frequency between the repeater transmit frequency and its receive frequency. In most parts of the US, the standard offset is 600 kHz on the 2m band and 5 MHz on the 70cm band, and can be either in the positive () or negative (-) direction. Most radios will default to the standard offset but you may have to select or offset. Usually a or symbol will appear in the display to indicate the offset selected. So you would enter 447.725 MHz into your radio, make sure the offset is set to 5 MHz and select as the offset direction. You can verify that your radio is programmed correctly if you see 447.725 MHz displayed during receive, which should change to 442.725 MHz when you push the transmit button. This is normally a two-step process: set the tone frequency and then enable the tone. Sometimes this is done with one selection (with Off being an option for the tone frequency). Some radios have separate settings for the transmit tone and receive tone. For now, just leave the receive tone off, since it can be a source of confusion. Most radios display a T somewhere on the display when the tone is enabled. After listening on frequency for a minute, transmit and identify using your callsign. On most repeaters, you will hear a short transmission coming back from the repeater along with a courtesy beep. A courtesy beep is just a short audio tone or tone sequence that occurs after someone finishes transmitting.
