Kelly:
Attempt to kill the messenger... ancient philosophy there, but why doesn't it surprise me the clueless always fall to it when out of legit arguments?

Imagine if that intellect were used for good....... ;^) That's what millions asked about Dr. Ted Kaczynski the Unabomber. CW provides a 10dB path gain over SSB with a simple twist of the mode selector knob. Can't wait to find out what the path gain of CW will be vs. all the furiously hyped HF digital modes. None of which actually exist 10-15 years later of course. Big surprise huh? Wow! 10 db? I knew it was superior. I didn't know it was that much superior. Yup. Same net effect as adding an amp. Go to 20 or 40 and tune an ssb signal which peaks at S4 on ye olde S-meter. Then spin the knob counterclockwise and find a CW signal which also peaks at S4, crank in the CW filter and ponder the difference in intelligibilities. The 'ole power density thing at work. But I am firmly convinced that OOK CW coupled with the processing power of "wetware", is the bottom line of getting the message through. You're there. Now the worst conditions won't happen every time of course, but they will happen some times. Huge variable there Mike. The inherent gain of CW is a very big deal in weak signal work. But if if an op's jollies come from being able to kick his feet up on the desk and yak his buddies with his RX RF gain at half mast then S/N ratios, whizzy front end dynamic ranges and path gains are irrelevant. Depends on what the particular op is into. RF gain knobs . . yessss . . "just in case" lemmee clue you about an HF dxers dirty little secret: The band is hot, big signals everywhere, yer ears are getting pounded and ya can't quite copy the new one in the muck. You have a big rig with DSP and hardware filters out the wazoo and a gazzilion buttons and knobs on the panel. Been there I dunno how many times. Took awhile for me to finally get the message many years ago but my best buddy in these situations is the lowly and usually ignored RF gain pot. Beyond this comes the subject of "operator skills". Oh Good Lord I forgot again: Discussions about operator skills have nothing to do with technical or policy "matters". Who in the hell (PMF) said THAT???? Heh . . . ! Operator skills are intrinsically a part of Amateur radio policy. Otherwise why do we have people who are trying to remove operator skills from the equation? Bwaaaaahaha! - Mike KB3EIA - w3rv |
