俺目前心目中最理想的qrp机器
qrp hf transceiver
--------------------------------------------------------------------------------
ic-703
--------------------------------------------------------------------------------
this new model is being designed as a portable hf transceiver that utilizes the design excellence and body of the very successful ic-706 series. it will be similar to an ic-706mkiig without the vhf and uhf bands, and is a model in a new genre that has an automatic antenna tuner built-in, low consumption circuit design and large external battery for field use as a portable hf qrp unit.
this new model will appeal to ham user’s who require a convenient portable hf unit, and will be an ideal long distance communications device for sparsely populated territories where set-up of normal communication infrastructure is expensive and impractical.
<features>
relay type antenna tuner unit built-in, 1.9-30mhz coverage
(for 50ohm load antenna. does not match to a wire antenna
new low current consumption circuit design to obtain longer battery life
large capacity external battery pack and antenna suitable for field operation, will be set as options
suitable for not only ham radio operation, but is an excellent unit for long distance communications in remote mountainous or desert areas where effective communications are not readily available. also, is perfect as a communications solution for specialized applications.
quick power set function to make qrp operation efficient
dsp built-in for auto-notch and noise reduction functions
(dsp functions are equivalent to ut-106)
max 10w output. adjustable in 10/5/1/0.5/0.1w steps
(5w when using 9.6v batteries)
memory keyer function built-in
multi-use versatility for the home or shack, mobile dx’ing in your car and as a field unit in the outdoors
