Alan -- read the manual and make a cheat sheet
Here is a generic guide Maybe best to walk before you run. First tackle the easy one, program a simplex channel. Then try programming for a repeater not requiring PL for access. Next, program for a repeater that does require PL to access (Pled repeater). For a simplex channel, first determine how to access the VFO and put in the desired frequency. Next, find the information for offset. Check that the offset is neither plus or minus, i.e., it is in simplex, then memory write all. ------------------------------- For a Pled Repeater, invoke the VFO mode and enter the repeater output frequency, set the offset value (e.g., 600 kHz) plus or minus as required. Next enter the tone frequency, tone activation, then memory write all. Many beginners enter the tone frequency, but forget to activate the tone. If you have trouble , there are pocket guides at URL: http://niftyaccessories.com/index.html Or get a programming cable and software -- see AES or HRO stores. ---------------------------- Here is how a repeater works In the illustration above -- (sorry can't post a pic on a NG), the mobile station wishes to communicate with both the base and the pedestrian with a Handi-Talkie (HT). But the mobile, base, and HT are too far apart, too low in altitude and blocked by the mountain. So the mobile transmits on 146.130 MHz to the mountain top repeater. The repeater processes the FM signal and simultaneously transmits the information on 146.730 MHz. Both the base and HT are in the receive mode (146.730 MHz) and pick up the communication from the repeater that was transmitted by the mobile station – slick huh? When the HT wishes to transmit (when the mobile station is done), the user presses the mic button and the HT will automatically switch to transmit mode and transmit at 146.130 MHz, the other two stations, when not transmitting, automatically go to the receive mode and receive the communication on 146.730 MHz. You'll may hear this repeater referred to as "The 73 Repeater or the Mount Stratosphere machine". Repeaters are not parrots (listen then repeat), so repeat is perhaps a misnomer, as it doesn’t listen, store, and then after a delay re-transmit, it does this simultaneously. For repeater operation, our transceivers have to be preset or programmed to transmit on one frequency and receive on a different frequency. This is referred to as offset, split, input/output. See conventions for Offsets at the end of this chapter. For an offset example, consider a repeater that hears you as you transmit on 146.130 MHz (input), and repeats you onto 146.730 MHz (output). The amount that the receive frequency is offset from the transmit frequency is called just that -- the "offset" or "offset frequency". Sometimes referred to as "split". In this case a 600 kHz offset. Since this repeater receives below the transmit frequency it is termed a minus offset. A repeater that receives on 147.130 and transmits on 147.730 MHz has an offset of plus 600 kHz. Repeaters that have outputs in the lower part of the 146 MHz portion are often plus offsets while those operating in the upper portion of 146 MHz are usually minus offsets. For the 145 MHz range – splits are minus, and for the 147 MHz range – splits are plus. See your repeater guides. Most of the new rigs default to the standard offsets. In some areas, repeaters operate on a reverse split – check you repeater guide. Although 600 kHz is a standard offset for 2 Meters, other "oddball splits" are sometimes used, but rarely. An easy way to remember offsets is (+) Plus Offset = Transmit UP. (-) Minus Offset = Transmit DOWN Good Luck "Alan D. Woodford" wrote in message nk.net... I am new to ham radios. I live in Norcross, Georgia. I haven't been able to communicate with any one yet. I have a Vertex VX-150. Do I have to connect to a repeater to converse. If so, what steps do I take to connect to the repeater. The nearest one to me is Stone Mountain W4BOC 146.760 - 146.160 107.2 . I intend to join a amateur radio group this month. Thank-you in advance! Alan D. Woodford KI4BSP |
