Someone wrote "You don't need a linear unless you're on 80 meters - then
you really need a biggie" Agree and disagree For example, let's start with a 100-Watt exciter then add an afterburner of 800 Watts. Doubling power is 3 dB and an S-unit is 6dB. So from 100W to 200W is 3dB, 200W to 400W is 3 more dB, and 400W to 800W is 3 more dB for a total of 9 dB or only 1-1/2 S-Units possible increase on the receiving end. One can achieve almost the same result with a 3-element beam. BUT Although one and a half S-Units does give a little more oomph while working a pileup, it really comes into play for weak signal work where if it gets you just up out of the noise on the receiving end, two way QSO's may be possible where without the linear, the DX just can't copy. I can attest to this many times on any band. On the other hand I have worked DXCC - QRP - 5 Watts A lot depends on propagation (of course) -- CL -- I doubt, therefore I might be ! |
