      Man , Operator , other dx-ers , is very very simple detections . To receive fenomens of athmosphere correct need .
      1 antena 90Mhz with 3 elements , 3dB maxim reception in Horizontal polarization . Fenomen not receiverd in Vertical .
      2. Radio to little sensibility <0.8V from antena . AGC from RECEPTION dubling or TRIPLING to receive other low signals .
      Questions :
      1 What is avantaje from modifications?
      1.1 Modifications need to listen low or very low radio signals .
      2.Antena in Vertical polarization not functional correct or partially in sporadic , what is problem ?
      2.2 Problem is simple , Vertical sporadic is rare , normally is unsettled polarization to 140 - 180 .
      3 IN plane zone sporadic is agressive , not understand ?
      3.3 Nornally to decrease elevation sporadic up in levels , at 0M elevation rare fenomen is out of reception and reception very power . Sea level or ocean is zone from records or master dx .
      4. Alert is nountains zone , in my zone not functionally this alert? .. is a big problem or sporadic not appear in my zone?
      4.4 NO , sporadic appear in your zone , not have antena in H plane polarization or elevation is big , Rules from mountain : 1000M altitude down 4dB/M , at 2000M 9-10dB/M .. is normally !
      5 Man what is problem .. sporadic attase in info is 52Mhz and radio received sporadic with radio in band 2 ?
      5.5 no problem spoadic kit mensure no calul real real . Calul aproximation MUF in athmosphere . Rare Muf sonde indicate real MUF >200Mhz .In the calcul from MUF reception : 53Mhz is partially dubling from 106mhz or MufX2 .

                    pe gradio clustere si pe grupuri sa vorbit de cele 2 zile in care pamantul a facut "moatze" si shuvitze . Eu am luat manual pozele si le-am pus pe forumuri sa vada si lumea ce sa petrecut , adica am tinut la curent cu ce e mai interesant

                    acum daca tot zicem de "coana aurora" zicem si de MUF ce a devenit betiv rau de tot in europa si cu valori de iti vine sa te faci ca razi .. 15-spre 29mega si evident sa prinzi semnal garla pe 50 si sus in 88-108 ca deh asa e acu la moda .
                    Mai este ceva de spus cu america , cele 2 zile de foc ale sporadicului , defapt nus 2 exacte ci vreo 32 de ore in care sudul americii de nord a fost maturat de sporadic si multihop sporadic . BUN si la mai mare , dar pentru noi europenii si pentru ei japoonezii chinezi indienii a fost de plans ca era sporadic cu 10-le de minute si foarte varza . poate asteptam o ameliorare , sau cum zice un grec , da domn'le asa facea in 1997 spre 1998 se nasolise rau europa si misca slab si 50mega care e cea de baza pe E . Acum dupa scaderea asta poate scapam de anomaliile de deschideri E ce se aseamana cu tropo si poate avem sporadicul spre parametrii naturali . EH de unde sa stie ala ca de la modificarile repetate ale climei ionizarea se face si ea dupa "ureche" :P si ca se naolestie si ea la randul ei !

                    revin cu ziua de azi
