Apparently, due to a design flaw in the original model, you can easily burn
out the 20 meter trap by running legal power. I destroyed mine running 600 watts, and another ham burned his out doing the same thing. Cushcraft can't replace the individual trap. I've obtained a spare 30 meter trap from another ham and am modifying it to replace the bad 20 meter trap. I don't know if this will work or not, but I had great success with the R7000 during the 2 years I had it. I worked over 280 countries with it and was very pleased with its performance. Dave AA1VX |

Thanks Rag, Ken and Dave
Believe me Ken ALL inputs and experiences are of value when it's 'head-scratching' time. I, too, have used verticals in the past and found them very good. Thanks, Rag, for the tip about the lower tube - I'll check this out.Much better to fix it before it's broken in this case. Dave - Thanks for your tip about the traps. You may be interested to check out the website at: http://www.qsl.net/ei7ba/r7_vertical.htm where EI7BA has listed the resonant frequency of the various traps. Guess you might have these already though. Thanks again everyone. I think I'll go for it. Frank GW3CNM |
