    ASC-1 Question

    arlo time for humans and time for micro processor is not on same scale !!! electronics can manage many moves in a short time . i have an octagon sf8008 with openatv or openpli , i know what you talk about : positioner is starting while we select a sat in large list of sat , but if...

    ASC-1 Question

    as time goes on i have find all source of lost pulses . today i never have to Resychronize Satellites (except if a power shut down occurs while moving) in my software i count pulses during moves and still count 50mS after stop it s enought . when motor stop no pulses can occurs...

    good job ! good idea to change transformer in vbox models ! do you find a truck full of titanium cases ?? do you read any software in vboxes ???

    ASC-1 Question

    hi guy ! what is this moded titanium ? a prototype model ? or you have just take the box and put something else in it ? Why two LCD with 2 different sat ? does it drive 2 dish ? my project : https://www.satelliteguys.us/xen/threads/positionner.382806/...

    hi rodrigo i have read your latest post on FTAFORO (with google translation) in the last post you are talking about the pwm utility ! i have seen the same problem with my SF8008 (when there is no signal, receiver send diseqc command always and always) i have filtered command from...

    waveguide calculating

    i am studying av-comm polarizer and "polopipe" (from brazil) (device for convert circular to linear) i have found some calculation about wavelenght in pipe but i have two variant of the same equation : LG = L / (racine (1 - ( L / (2.d))^ 2)) LG = L / (racine (1 - ( L / (1.6406.d))^ 2)) lg...

    thanks for your answer ! i do pwm supply for actuator at about 5khz then cycle is about 200µs and i have conflict with interupt routines so my duty cycle run from 25% to 60% and above i put 100%¨! i will try to 800hz/1khz (1mS) and see if it s ok !! do you manage mechanical...

    problem was fixed : there are buried cables in ground , there are out of order !!! new cables works well !!

    hi rodrigocn i have seen your videos on FTA-FORO i have some questions : does the pmw frequency is 50hz ? (like in video) what is your concept dish1/dish2 ? what is diseqc command for step move (10 pulses for example?)

    i m using micro-controller , i think that problem comes from "diaphony" i cant go upside 5khz (200µs) with this chip (89s52) but if i use dedicated chip like a small pic16 i can reach 20K !!

    positionner

    thanks all in my device pwm frequency is 5khz , i thought it was not enough but if its ok with less 1K i can try it the smr1224 of my friend is like Trust said : no electronics just like a classic actuator the problem is : as soon as the motor power is pulsed the reed switch line is...

    hi rodrigo i have implemented PWM in my positioner : it s works perfectly with classic actuator (18 or 24 inch arm) but for an smr1224 ( a friend of mine) it s erratic sometime motor dont run or stop anywhere when power supply is low motor dont start !! do you manage mosfet all the...

    i seen you had encountered some troubles with lnb switch ! to prevent signal loss , i have picked diseqc signal in receiver before tuner unit : the diseqc modulate signal is injected in tuner unit but at this place there is no HF signal so i can put a wire to an rCA cinch and there is no...
