Defect problema la un radio JUPITER 2

Recommended Posts

Buna!!

 

Am intalnit o problema la un radio JUPITER 2, nu functioneaza pe gamele de unda medie(UM) si lunga(UL).

Pe gama de UM receptioneaza numai postul Bucuresti iar pe UL nu receptioneaza nimic.

Am inceput cu verificarea de la antena de ferita am legat toate bobinele corect conform schemei  de principiu.Apoi am verificat claviatura (pare totul corect pentru ca pe unda scurta functioneaza pe toate trei gamele.

As vrea sa aflu daca problema este din cauza unei piese defecte sau ceva contact imperfect atunci cand rotesti condesatorul variabil pe UM si gasesti numai postul cel mai  bine receptionat,sau problema este si in alta parte.

 

Multumesc!
