ALINCO´s DX-70 ist einer der kleinsten HF + 50 MHz ALL MODE Transceiver mit absetzbarer Front auf der Welt. SSB, CW, AM und FM sind ebenso Standard ab Werk wie schmale und breite ZF-Filter, RIT/TXIT und IF-Shift. Der durchgehende Empfänger deckt die Bereiche 150 kHz – 30 MHz und 50 – 54 MHz ab. Und auch die CW-Freunde werden Ihre Freude haben: Wählbare CW-Ablage, BFO-Invertierung, BK in 3 Variationen. Alles in allem:
Klein, leicht, leistungsstark und vollgepackt mit Features, also ein Gerät, das Sie eigentlich haben sollten.
