Merita sa mentionez ca legatura radio a fost facuta in FM/CH35, iar Leo lucra QRP10w.:-)

Prima schimbare de frecventa intre teorie si practica

Uite asa se face profitu' cind din una faci doua ! :-)

Schema electrica prevede clar doua fitre ceramice pe 10...Mhz plus inca un filrtu ceramic dublu pe a doua schimbare de frecv. 455 ... deci, in total 4 filtre ceramince care dau per total un filtru decent de 3 kHz.... asta in terorie, caci in practica lipseste unul, iar rezultatele se simt la receptie mai ales la urechea lui 010.

Si uite asa, de voie de nevoie, m-am apucat si de "microchirurgie" (sau munca de "chinez batrin" cum vreti :-)  ) in locul robotilor de pe linia de montaj ... si-am facut un transplant din una de acelasi neam. Nu-i de loc usor de facut, dar se poate si merita.
Problema asta este la multe modele de statii, nu le dau cu numele, dar sunt "brenduri" mari chipurile. Altii, la modele ieftine si populare au pus tot  un filtru pe prima schimbare, intetinoat din motive economice, caci la serie mare se aduna ceva la pretul de cost... mama lui de profit si plan caci au umplut lumea de gunoaie!

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).
