Am observat ca sunt cativa membrii de pe forum care sunt radioamatori sau
care cocheteaza cu ideea de radioamatorism (printre cei din ultima categorie
m-as numara si eu).
Am putea sa discutam aici despre ce e legat de subiectul asta: walkie-talkie,
transceivere, propagare etc.

Sa incep eu cu o intrebare: Care statii portabile emisie-receptie CB s-ar
merita a fi cumparete la noi in tara (am vazut ca site-ul okazii abunda in
oferte), luand in calcul raportul pret-performanta ?

Intradevar,Motorola e in top,am lucrat cu asa ceva,in schimb ma omora programarea lor.Softul lucra in DOS si uneori mergea,alteori nu pe acelasi calculator.Daca stie cineva despre modificari privind extinderea TX si RX la unul din modelele Yaesu FT 7800,8800 sau 8900 (ma intereseaza TX pe la 460-470 si RX de la 108 AM in sus) as avea nevoie pentru a alege unul din modele.Si cine este din Bucuresti,poate ne auzim in CB.
@ Parabelum:portabila CB cea mai reusita mi se pare Alan 42,mai este una mai veche pe net in oferte dar este numai AM,deci...Din cite stiu,are 2 benzi.Daca doresti o statie fixa,iti recomand un Magnum S45,eu din asta am si are cam tot ce vrei:AM/FM/SSB,shift ca sa poti lucra intre canale(cu 0 in coada),40W reali,peste 400 canale(10 benzi+ citeva canale pe fiecare cu indice A),ecou,roger beep,PWR reglabil.Pretul e undeva in jur de 1000 lei.Singurul dezavantaj pe care il vad este dimensiunea,e mai mare decit un casetofon auto.Pentru mobil,ideal mi se pate Midland 48+,micuta,benzi destule....

Eu am un Alan 100, foarte multumit de el. Daca ai antena buna, face minuni.

Din pacate statiile GMRS/FRS nu functioneaza in benzile libere din europa. Doar in state. La noi merg CB, 40 canale, 4W, AM/FM (27MHz) si PMR, 8 canale, 0,5W, FM (446 MHz).

Gata,a venit si FT 8800E.Ma interesa extinderea emisiei in 420-470 ca sa pot sa o folosesc cu statii dedicate PMR.Desi ecartul de frecventa e diferit,functioneaza si asa,banuiesc ca cele din urma nu sint foarte precise Wink .

@Agrig: Multumesc pentru linkuri....acum sa gasesc un pistol cu aer cald si pe cineva caruia nu ii tremure mina sa scoata SMD-ul ala de acolo Very Happy

de acord cu tine, avem repetoare ,sunt pentru 2 frecvente care le folosim pentru comunicare oficiala si alea merg pe 20-30 de km dar avem si o frecventa intre noi care la mine a mers cam 5 km in linie dreapta ,doar niste paduri au fost intre noi fara dealuri, daca vorbesc dintr-o vale ,de unde cu mindrie servesc omv-ul nu ma aude nici la 1 km.Astea de la metro merg la vinatoare 500 m max 1km sa si intelegi ce spune partenerul.intentia mea nu e sa contrazic pe cineva eu spun ce am verificat

Era o vreme cand si eu cochetam cu radioamatorii (YO5ONS). Si eram la un concurs pe varful Vladeasa (eu cu montarea echipamentului si admirat peisajul si altii cu ciocanitoarea) iar la intoarcere povesteam cu cei din oras (Cluj Napoca) cu o satatie Iaesu mica de mana. Nu stiu ce putere avea, dar se auzea clar. Asta pana am intrat intr-o zona in care aveam un delusor de max 10 m mai inalt decat noi si nu am mai receptionat nimic. Iar in armata aveam niste statii Motorola cu care discutam pana la max 20km (le-am incercat pana la 15-16km si functionau), asta tinand cont ca aveam statiile alea mari R1700 (de 12kg bucata cel putin) care bateau cica max 15km fara retlanslatie. Si acum mai am o statie emisie-receptie Philips modificata, dar care nu a mai fost folosita de ani buni. Nici macar nu stiu daca mai functioneaza.

Acu voi faceti misto? Question Question Question Dau si eu un indicativ care nici nu mai credeam ca e valabil si ma trezesc cu numele pe forum, si nici macar nu e la sectiunea cu prezentarile (ce-i drept, acolo trebuia sa il postez eu, dar nu mi s-a parut necesar). Nu ma deranjeaza, da spuneti-mi si mie cum ati aflat, ca sant curios.
