![]() "Old Ed" wrote in message nk.net... Hello All - This reads like a tongue-in-cheek bit of good-natured trolling... but I have added a few comments, just in case some newbie takes it all too seriously. "Reg Edwards" wrote in message ... S-meters are nothing else but power (input) meters. Actually, the tradition has been to characterize S-meter calibration (if I may call it that) in terms of voltage, not power. Of course, the two may be translated freely if one assumes an input impedance. More significantly, the typical signal-strength indicators on receivers are not ANY kind of "meters"--in the sense of comprising calibrated test equipment. A minority of higher-end receivers MAY receive a quick stab at meter calibration in the alignment process; and they MAY have flat enough gain versus frequency for that calibration to apply roughly across their frequency coverage. But I wouldn't count on it. Amateurs and meter manufacturers long ago learned, that when giving signal strength reports, it is more convenient to refer to meter indications in terms of S-units rather than micro-watts or nano-watts. Hams can use S-units, but I really prefer antenna manufacturers to stick closer to physics and give me real gain in dB or numeric. Ed wb6wsn |

Hi Other Ed -
I have to agree that S-units have little or no role in specifying antennas. Ed "Ed Price" wrote in message news:Vnbqd.4491$KO5.2116@fed1read02... Hams can use S-units, but I really prefer antenna manufacturers to stick closer to physics and give me real gain in dB or numeric. Ed wb6wsn |
