Stories & reviews

Grandi prestazioni!

Elecraft KX3, Portable HF/VHF Transceiver

Ha praticamente tutto quell che si può trovare in un apparecchio di fascia elevata: dal doppio VFO ad una serie impressionante di filtri audio, dal decider PSK e RTTY incorporati (puoi trasmettere in CW e lui "traduce in PSK o RTTY) fino al doppio audio, con cui senti, in un auricolare la stazione DX e nell' altro il Pile-Up! Certo, non è economico, ma il paragone va fatto con i "grandi" classici dell' HF. 1.200 Euro, senza scheda audio, senza microfono e senza accordatore, per di più ha solo 10 Watt...ma ne sono entusiasta!

Wonderful Rig

Elecraft KX3, Portable HF/VHF Transceiver

The KX-3 has proven to be an excellent rig for me. I purchased it factory built after reading reviews and the product test on the ARRL website, and it has not let me down so far. So far I've worked sideband, cw, psk31 and rtty with great success. The little rig is tolerant of power supply, running from a cheap RadioShack power supply, battery or solar cell without a hiccup. When I accidentally over voltaged it, it simply turned itself off and suffered no damage. The internal ATU has tuned nearly every strange antenna or wire I've connected to it, usually within 1.3/1 swr. With properly made antenna I have been able to work Europe, Australia, and all 50 United States. 10 watts was enough to earn my WAS award with my horizontal loop in my attic crawlspace, low dipoles thrown into trees, and even a buddypole-style homebrew. It's a great rig that I'm not parting with anytime soon.
