This subject has recently come up on the Topband reflector. I look at this from the question: "How much is a dB worth to my score in a DX contest ?" Information about N1UR's contest performance prese
I suspect that the magnitude of the difference probably depends on the contest. Quite a few years ago, N6ZFO, whose job in pharama development included lots of statistics, did an analysis for NCCC sa
All these 2.6 to 2.8 per cent per deciBel are for CW only. Has anybody invested time to analyze the dB effect on SSB score? My guess is the difference is bigger on phone. 73, Jukka OH6LI ____________

Hi Tim May I ask, what antenna do you use? Thanks Tom KA2D My interpolation on CW and RTTY using my personal logs, for 24-34 hour efforts in 48 hour contests and almost unchanged antenna system, afte
Certainly, Tom! My antenna is a 130-foot doublet, up 75 feet between trees, fed by tuners and ladder line. On 160M the antenna is fed by tying the ladder line together at ground level and feeding it
I would postulate that the worth of a dB is not linear, but rather, there is a tipping point. If Tim was using a beam at 50-70 feet on the high bands, I think his results would be more in line with t
Dave, while those statistics were my personal station, I also looked at other scores in top-5 or top-10 boxes of the big DX contests. I would generally say that the #5 NA HP entrants have twice the Q
My interest in this is related to the 150 watt limit for LP in the ARRL Rtty Roundup. My 100 watts is more like 80 watts after the so2r bandpass filters and stubs. Therefore I could gain almost 3db b
