Transceiver HF SDR 1.6-30MHz ENVOY
Re: Transceiver HF SDR 1.6-30MHz ENVOY
Tehnologia e interesanta, insa e un transciever complet inutil pentru radioamatori din moment ce nu are un mod VFO.
Re: Transceiver HF SDR 1.6-30MHz ENVOY
Interesant, dar dupa cum scrie si producatorul, aparatul este gandit pentru:
- scop umanitar
- comercial
- siguranta publica
- securitate
- uz militar
Eu personal as prefera un KX3...
Toate cele bune,
