1000 foot longwire antenna's
dxAce raised the point that he would prefer to upgrade to a 1000 foot
antenna rather than upgrade to a better radio. This is a bit like which came first? the chicken or the egg? I have had extensive experience of using 1000ft longwires or beverage antenna's on my DXpeditions over the years and indeed they do pull in the signals something awesome. But they also pull in more interfering stations that want to blot out your faint DX target, and also whatever QRM/RFI noise is floating around, they pull more of that in too. So at the end of the day it still means it is better to DX with a top end radio that suppresses and minimises the offending signals and QRM that are interfering with your faint DX target. Over the years I gradually upgraded my radio's to what I thought was the ultimate, a Drake R8B. I was quite satisfied with that until I was loaned a Rohde & Schwarz. Although the R & S did not have any more bells and whistles than my Drake, it was so clearly superior to my R8B that from then on I hankered after a better radio. The R&S just pulled in faint stations that did not even register on the R8B and then was also better able to resolve to audibility stations that were interfered with much better than the R8B. So I watched developments and then my good friend Guy pointed me towards the Icom IC-756PROIII, which I later acquired. This radio was indeed better than my R8B, see: http://www.dxing.info/equipment/icom_ic756_plimmer.dx So the 756Pro3 has really proved itself in the field, culminating in the catch of a lifetime: 1410 Khz, CFUN, Vancouver BC, Canada, some 14,000 miles away from the Seefontein DX site. Whether or not I would have got this catch on my old R8B is a moot point - I don't think so as it was extremely faint and on the border of audibility, and my DX mates didn't get it either. So I am happy that the 756Pro3 paid for itself and that is why I am now upgrading to the new Icom IC-7700 which should be here in April. If I get only one more rare catch I will be satisfied that the 7700 has been a worthwhile investment. But to keep things in perspective, I think the things that are important to good DX reception are, in order of importance: 1st.] A decent antenna, the best you can afford or rig up. 2nd.] Location. Most of us live in the city or suburbs and are either in condo's or on limited size plots, so our options are limited. That is why serious DXer's go to a lot of trouble and expense to find the "ideal" DX location. When you find a decent place, the results are VERY rewarding. 3rd.] The radio. again, get the best you can afford. The results just get better and better. I would liken our hobby to any sport. If you take golf and Tiger Woods for example. He has only the latest and most expensive cutting edge equipment. If he gets the latest $3000 putter and it allows him that extra inch nearer the hole, he is satisfied. So it is with radio gear and antenna's.
