    Can anyone tell me how to configure the KPC3 for stand alone (home base, not mobile) use for APRS?

    Try these settings. They worked for me after changing the obvious callsign, mynode, and the appropriate other location specific settings.

    Initialization file for configuring KCP3+ as an APRS digipeater
    Find and replace "callsign" throughout this file with the desired callsign.
    Edit the LT1 through LT4 lines to include the coordinates and PHG of the digipeater
    along with any beacon message string desired.
    Edit the LTP1 through LTP4 lines to reflect the desired paths to be used for
    beacons at the time intervals defined in BLT1 through BLT4.

    After editing, delete this commented section and save the file under a new name.
    Use a terminal program such as Procomm or Windows HyperTerminal to connect with
    the KPC3+ Verify you can get a CMD: prompt, type commands into the KPC3 and see
    responses. Then do a text file upload to read this file into the KPC3+ Set the
    terminal program to add a delay of 100-200mS between lines to give the KPC3 time
    to process each line.

    Note that this listing is a DISPLAY dump from an already-configured KPC3+. The TNC will choke on this listing if you just try to
    edit and upload this list. This version has been edited for the correct command for SETTING, not just Displaying the settings.

    LT 1 - 4 should all be the same. The first set of numbers are your latitute and longitude. (Important-make sure that the ! character is in front of first digit) the seconds are in decimal.
    ie: 15 seconds would be entered .25 30 seconds as .50 etc.

    Antenna
    Height/Gain/
    Directivity
    The 7-byte PHG (phgd) Data Extension specifies the transmitter power,
    effective antenna height-above-average-terrain, antenna gain and antenna
    directivity. APRS uses this information to plot radio range circles around
    stations.

    The 7 characters of this Data Extension are encoded as follows:
    Characters 1–3: PHG (fixed)
    Character 4: p Power code
    Character 5: h Height code
    Character 6: g Antenna gain code
    Character 7: d Directivity code

    The PHG codes are listed in the table below:
    PHG Codes

    phgd Code: 0 1 2 3 4 5 6 7 8 9 Units
    Power 0 1 4 9 16 25 36 49 64 81 watts
    Height 10 20 40 80 160 320 640 1280 2560 5120 feet
    Gain 0 1 2 3 4 5 6 7 8 9 dB
    Directivity omni 45 90 135 180 225 270 315 360

    The height code represents the effective height of the antenna above average
    local terrain, not above ground or sea level — this is to provide a rough
    indication of the antenna’s effectiveness in the local area .
    The height code may in fact be any ASCII character 0–9 and above. This is
    so that larger heights for balloons, aircraft or satellites may be specified.
    For example:
    : is the height code for 10240 feet (approximately 1.9 miles).
    ; is the height code for 20480 feet (approximately 3.9 miles), and so on.
    The Directivity code offsets the PHG circle by one third in the indicated
    direction. This means a front-to-back ratio of 2 to 1. Most often this is used
    to indicate a favored direction or a null, even if an omni antenna is at the site.
    An example of the PHG Data Extension:
    PHG6570 means a power of 25 watts, an antenna height of 160 feet above the average local terrain,
    an antenna gain of 7 dB and maximum gain omnidirectional. PHG6573 would be same with directivity
    to the southeast or 135 degrees.
