Amateur Radio Direction Finding - ARDF

From Wikipedia

Amateur radio direction finding (ARDF, also known as radio orienteering and radiosport) is an amateur racing sport that combines radio direction finding with the map and compass skills of orienteering. It is a timed race in which individual competitors use a topographic map, a magnetic compass and radio direction finding apparatus to navigate through diverse wooded terrain while searching for radio transmitters. The rules of the sport and international competitions are organized by the International Amateur Radio Union. The sport has been most popular in Eastern Europe, Russia, and China, where it was often used in the physical education programs in schools.
ARDF events use radio frequencies on either the two-meter or eighty-meter amateur radio bands. These two bands were chosen because of their universal availability to amateur radio licensees in all countries. In the UK events with somewhat different rules are also run on 160 meters. The radio equipment carried by competitors on a course must be capable of receiving the signal being transmitted by the five transmitters and useful for radio direction finding, including a radio receiver, attenuator, and directional antenna. Most equipment designs integrate all three components into one handheld device.

    Pocketsat+ - Satellites Tracking Software For Your PDA and iPhone


    PocketSat+ is a full-featured satellite tracking application for PalmOS and PocketPC devices. It is designed to be usable by both experienced satellite trackers as well as novices who are interested in knowing when they can simply look up and see satellites.

    Like PocketSat, its predecessor, PocketSat+ includes tools to predict when satellites in low-Earth orbits will pass overhead and potentially be visible. Unlike PocketSat, however, PocketSat+ can track any satellite, and can display real-time plots of multiple satellites on both Earth maps and Sky charts.

    Features of PocketSat+ include:
    Configurable to compute satellite visibility from any location on Earth.
    Track and plot real-time positions of up to 9 satellites simultaneously.
    Map view shows satellite position and orbit track on an Earth map.
    Sky view shows satellite position and path in the Sky.
    Flexible application clock can be set to any date and time as well as clock rate, allowing "what happens when…" experiments. You can make time stand still or even go backwards if you wish. A single button press restores the clock to current system time.
    "Pass" mode allows pre-calculation of satellites that will pass over a particular location during a given time span, including filters for minimum altitude and whether or not a satellite is lit by the Sun.
    Uses full SGP4 and SDP4 orbit propagation algorithms, allowing accurate tracking of any satellite.

    PalmOS PocketPC(Windows Mobile) iPhone

    P/S: copy this file to your PDA/iPhone and open it on pocketsat+, you can see lots of satellites name then select which one you want to track.

    How To Calculate Amateur Radio Simplex Channel

    The simplex channel between V16 to V47 is using 145MHz before the decimal point. So we just need to find the MHz decimal point.

    12.5 with the multiplication formula Channel.

    Example 1:

    V16 : 12.5 x 16 = 200
    So the frequency of V16 is 145.2000

    Example 2:

    V27 : 12.5 x 27 = 337.5
    The frequency for V27 is 145.33752.

    Frequency between V48 to V63 is using 146MHz before the decimal point. Then,

    12.5 V with the multiplication formula minus 200

    Example 1:

    V50 : 12.5 x 50 = 625 - 200 = 425
    The frequency for V50 is 146.4250

    Example 2:

    V63 12.5 x 63 = 787.5 - 200 = 587.5
    So the frequency for V63 is 146.5875

    P/S: After the decimal point, there are 4 numbers. If the result is 3 numbers, you need to plus 0 to fulfill the 4 numbers.

    Morse Code Chart

    Listen A -Z, 1 - 0 morse code ?


    Just for my reference ;-)

    Making and responding to distress (emergency) calls

    Before an emergency occurs, be sure you know how to make a distress call
    on a frequency where hams are likely to be listening, such as a marine ser­vice net or a wide-coverage repeater frequency. Store at least one of these fre­quencies in your radio’s memories, if possible. Anyone, licensed or not, can use your radio equipment in an emergency to call for help on any frequency. You won’t have time to be looking at net directories in an emergency. Do the following things when you make a distress call.

    1. If you need immediate emergency assistance, the appropriate voice
      signal is MAYDAY and the appropriate Morse code signal is SOS (yes,
      just like in the movies). Maydays sound something like: “MAYDAY, MAYDAY, MAYDAY, this is 9W2PJU,” followed by:
      • Your location (latitude/longitude) or address of the emergency
      • The nature of the emergency
      • What type of assistance you need — such as medical or trans­portation aid.
    2. Repeat your distress signal and your call sign for several minutes or
      until you get an answer. Even if you don’t hear an answer, others may hear you.
    3. Try different frequencies if you do not get an answer. If you do decide to change frequencies, announce to what frequency you are moving so that anyone hearing you can follow.

    If you hear a distress signal on the air:

    1. Immediately find something to record information. Note the time and
      frequency of the call. To help the authorities render assistance as quickly
      as possible, note the following information:
      • The location (latitude/longitude) or address of the emergency
      • The nature of the problem
      • What type of assistance he or she needs — such as medical or transportation aid
      • Any other information that is helpful.
    2. Respond to the call. Say “[Give the station’s call sign], this is [your call
      sign]. I hear your distress call. What is your situation?”
    3. Using Morse code, you send “[station’s call sign] DE [your call] RRR WAT
      UR INFO?” or something similar. Let the station in distress know who you are and that you hear them.
    4. After you acquire the information, ask the station in distress to remain on frequency.
    5. Call the appropriate public agency or public emergency number, such as 911. Explain that you are an amateur radio operator and that you received a distress call. The dispatcher either begins a process of asking you for information or transfers you to a more appropriate agency. Follow the dispatcher’s instructions to the letter. The dispatcher may ask you to act as a relay to the station in distress.
    6. As soon as possible, report back to the station in distress. Tell them who you contacted and any information you have been asked to relay.
    7. Stay on frequency as long as the station in distress or the authorities
      need your assistance.
