Marcin - ściągnąłem ta instrukcję co podajesz link i tam na st.6 NIC nie ma na ten temat [ani 100W ani 75W ??? ] Znalazłem w innej instrukcji takie cos i chyba sprawa sie wyjaśniła " cyt. The 6146B PA tubes are very rugged, and can deliver around 100 -120 Watts output depending on the band of operation, by a input of 180W in the SSB and CW mode. In AM mode the maximum input power is 45 Watt. This is due the fact that the SSB signal has just one sideband, which has only 25% of the power factor of a AM signal, so the tubes can deliver in SSB 4x the power of a AM signal, at the same dissipation. It is never a good idea to push the PA to the limit, it is much better to run the PA with powers around 150W input in SSB/ CW, the tubes will last much longer, and the difference at the receiving station is minimal. You will be surprised how many DX stations can be worked with low power. It all depends on an effective antenna, band conditions and operating skill, and not only big power: you have to double your power output to make a S-point difference at the receiving station! Pozastaje tylko u mnie dylemat czy te 100-120 wat co podaja tu powyżej dotyczy mocy wyjsciowej z włączonym procesorem mowy czy bez - bo różnica u mnie jest BARDZO duża 115W/75 W ??? |
