JT65-HF =mod digital pentru semnale slabe

JT65-HF este un mod digital pentru a realiza legaturi radio cu puteri  RF mici in antena.

Mai jos se poate observa ca daca mereu primesti in legaturile radio, modul JT65-HF, rapoarte semnal mai bun de -10dB, atunci TREBUIE redusa puterea de RF!

73s and have a nice weekend with QRP and DX!
