Transverter 28/144mhz

Recommended Posts

Din dorinta de a face un transverter 28/144 mhz am tot cautat pe net scheme si efectiv nu stiu la care sa ma opresc (am gasit prea multe HI...). Dorinta mea este o schema la care cineva a lucrat si facut acel transverter.Marian

Eu recomand transverterul Javornik http://lea.hamradio.si/~s53rm/JAVORNIK%20144.htm

De mentionat ca face conversia din 144/14MHZ.Se poate modifica usor pentru 28MHZ.

Un alt proiect ar fi http://www.kc5wa.net/suffolk/index.html , este asemanator cu primul.

Transvertere performante pentru traficul DX si EME mai poti gasi la http://www.iz4beh.net/progetti.htm

In incheiere o poza cu Javornik simplificat (nu este finalizat).

Am gasit si eu acele scheme dar ma gandeam sa o iau ma usor, nu prea am experienta si aparatura de masura necesara in uus si ma gandeam la o schema ceva mai simpla si cu componente care se gasesc pe la noi. Am vazut pe siteul http://yo4hfu.dmon.com/ ca ati inceput cu ceva mai simplu, cam la unul ca acela m-as oprii pentru inceput.

Acel transverter functioneaza destul de bine.La momentul respectiv am experimentat mai multe configuratii.Mi-a fost lene sa-i mai fac cablaj :ras: Aseara am facut o comparatie intre vechiul transverter si javornik.Ultimul a dat rezultate mai bune.In principiu toate schemele functioneaza, conteaza mult calitatea componentelor si executia.73!
