It can be easily carried in one hand. It comes equipped with a handle on the side, apparently for that purpose. :-) I agree - I still use my R-70 almost daily. Bought it new in 1981, still works quite well (its tuning arrangement is a bit weird at the "xx.000" MHz areas, but once you get used to that it's OK...). This was an impressive rig when it was first introduced - and with the Kiwa filters installed it can pull DX signals out of the mud as well as many of the current receivers in its class. It's still a tiny thing, hardly a "boatanchor" (unless one has a 1/12th scale model of a boat). I agree on the "xx.000" MHz switch-over. :-) That might have been a programmer's thing on what I speculate as a design argument at Icom...how to do switching to the adjacent MHz. They might have added some "hysteresis" on tuning but one can become accoustomed to it. I got no mods in this one. Still an excellent performer, actually - one of the best investments in radio equipment that I have ever made. I will agree to that. [I think we bought at about the same time] The tuning shaft encoder and very slight friction lock is still as good on mine now as when it was new. Over a dozen years. If only it had some of the features of the R-71 - direct frequency entry, capability for computer control.....oh well..... I thought about adding an outboard controller to have all the "memory" things but used the parts for other things. :-) It definitely needs an outboard audio amplifier and big speaker since the little one on the panel is not robust for anyone else but self. For a while I used an old Hi-Fi mono amplifier with it and an ancient 6" diameter speaker in a fair enclosure. Sound was just dandy then. Since wife and I had a major re-do of the roof and guttering, I've been meaning to try connecting to the end of the 45-foot run of seamless alumininum gutter on the downhill side (it is 22 feet longer on the uphill side, but closer to power lines). Need to recalibrate the Noise Bridge and see what kind of weird impedance it presents at different frequencie...and the change of that in the rain to come. :-) Sort of a "low-slung long wire" in a way. [watch for all the detractors on that...heh heh heh[ In this in-the-hills location there's little chance for low-angle skip arrival from north to east...all the fancy-schmansy antennas won't help getting Yurp or the UK here. Nevis rules. Excellent on Ozzyland and the home of the Middle Earth and LOTR. Strange that so MANY signals on HF originate from stations whose operators don't have to have a code exam...or even an amateur radio license. :-) Outside of the ham bands, of coarse. :-) |
