NASLEDNIK SERIJE IC-706, QRP VERZIJA

Categories: ,
General Details

 

Maksimalna portabilnost

Serija IC-703 je dizajnirana za upotrebu na otvorenom. Opciona baterija, BP-228 obezbeđuje 5W izlazne snage* i 7 časova* rada. Kompletna oprema neophodna za rad na terenu, uključujući i antenu, može se spakovati u opcionom rancu LC-156.
* 2W u AM režimu rada.
* Tx:Rx:Stand-by=0.5:0.5:9 u SSB režimu rada.

 

Automatski tjuner za antenu

Ugrađeni automatski tjuner za antenu pokriva fekvencije od 1.8MHz do 54MHz.

DSP mogućnosti

 

Ugrađena DSP jedinica omogućava funkcije redukcije šuma i automatskog filtra nepropusnika opsega.
* U nekim verzijam neophodna je DSP jedinica UT-106.

 

Ostale funkcije

  • Odvajanje kontrolera korišćenjem opcionog kabla za odvajanje, OPC-581/OPC-587
  • TCXO jedinica stabilnosti ±0.5ppm
  • Mikrofonski priključci na prednjem i zadnjem panelu
  • Terminal za prenos podataka brzinom 9600bps
  • RIT, VOX, poništavanje šuma i kompresija govora
  • Memorijski radio-telegrafski taster sa 3 kanala
  • RTTY (FSK) režim rada
  • Pozadinsko osvetljenje tastera
