    Ako nekoj go zanima odrzuvanje na radio vrski preku meteori eve eden program koj ke vi pomogne i sto e najvazno ne morate da imate poznavanje od telegrafija,kompot se ke zavrsi mesto vas.Za pochetok eve go linkot za simnuvanje na programot.

    Very Happy Smetam deka ste go instalirale programot i sega treba da go testirame.
    Za odrzuvanje na radio vrski preku meteori vi se potrebni slednite raboti:
    1. Radio stanica bilo kakva samo da ima ssb na 144mhz.
    2.Antena yagi horinzontalno postavena okolu 10db pa toa ke biide 7el yagi ili 6el yagi.
    3.linearno pojachalo okolu 50 wati pa i nesto pomalkuima sluchaevi na max protok i so 10 w e odrzana adio vrska.
    4.modem za povrzuvanje na radiostanicata so kompjuterot

    ISOLATED INTERFACE

    This circuit incorporates two 600-ohm audio transformers (T1
    & T2) and an RS232 powered optocoupler IC1. Preferably use an IC socket for
    IC1, for possible quick replacement! The purpose of the transformers and an
    optocoupler is to isolate the transceiver from the computer, keeping the
    interference from the PC to a minimum. Ensure that the screening on the radio
    and the screening on the PC are not connected together.

    Stereo 3.5 mm plugs connect the line in and out on the computer
    soundcard. Use the tip and earth only as in this application the sleeve is not
    used.

    To control the radio PTT, an isolated signal from the computers
    RS232 (RTS) line is used. If you have an available DB9 connector on your
    computer, use RTS (Pin 7) and ground (Pin 5). If you have a DB25 connector on
    your computer, use RTS (Pin 4) and ground (pin 7).

    VR1 is a 1K linear potentiometer used to control the amount of
    audio going to the MIC and is adjusted for correct audio drive to the radio,
    usually converting line (0.5v) to MIC (10mV) levels. The 1.2k resistor (from the
    Line Out) can be changed to a greater value if you are troubled by the pot
    always being at the bottom or top of the range or alternately by adjusting the
    computers audio out slider till the correct level is achieved. Operationally,
    audio levels are adjusted by the computer level controls or are incorporated in
    the software you will be using.

    The LED (high sensitivity type) is used as an indicator when the
    interface is in the transmit mode.

    It is suggested that the finished interface is put in a metal
    box and that the grounding is taken from the radio side of the circuit.

    :DSmetem deka sme go instalirale programo zapoznaeto so nego i napraven e
    interface za povrzuvanje na radiostanicata so kompjutero.
    Sledno e gradba na antena za 144mhz
    Najednostavna
    a dobra antena za pochetok spored mene e 7el DK7ZB na ovoj link moze da
    videte kako se
    pravi:http://tk5ep.free.fr/tech/yagi_vhf/en/yagi7el_g.php
    a moze i direkno na stranata na avtoro:http://www.mydarc.de/dk7zb/2m-short/7El-yagi.htm
    Mnogu uspeh vo gradbata
