Transceiver USDX

Recommended Posts

 Tot cautind ceva pentru a trece timpul mai usor in aceasta perioada, am dat de jucaria de mai jos:

pare o jucarie interesanta tinind cont ca foloseste o sinteza de frecventa care genereaza direct cele doua semnale defazate necesare si mai ales ca face toata procesarea pe un ATMEGA328, deci nefiind necesar un PC. Sigur nu se va mai vizualiza grafic o portiune de banda, dar si asa merita testat.

 Pina acuma am comandat FST3253 care au sosit deja din UK si astept sa fie gata si pcb-urile comandate in China, care vor sosi saptamina viitoare printr-un curier rapid.

 Sint curios de parerile voastre despre jucarie!
