Sursa in comutatie MOMENTUM MPS-52350, inside view

Photo prin amabilitatea colegului nostru "Blondu' " care a reusit sa "prajeasca" doua surse intr-o saptamina (una moderna in comutatie si alta clasica cu trafo) - o performanta de neegalat zic eu :-)

How to tune your CB radio without an SWR meter

In imaginile de mai sus se  poate vedea cum acordam ("calibram") o antena de CB radio fara sa folosim un SWR - metru.
Avem nevoie numai de o sarcina rezistiva (dummy load) de 50 ohmi si un banal aparat de masura digital (care costa mai putin decit un SWR-metru :-) ) pus pe masurare de curent (A), deci inseriat in circuitul de alimentare al statiei, si prin simpla comparare a curentului consumat de statie ne putem da seama ca totul este ok, adica consumam si "incarcam" putere in antena iar etajul final nu este deloc supra solicitat.
Prin aceasta veche si simpla metoda se poate vedea ca am un swr sub 1:1,5 fara probleme. Am facut masurarea pe putere mica QRP (4w) dupa care antena a fost buna si pt Avanti Grande (QRO).
