Hello, Twist

Yo' Jim.

Dave was referring to 'S' units at the other end
of the circuit.

When I took exception to his words, he was speaking of S units received
by another radio, arrived via the peaking of the 4 watt radio that was
of topic..

One 'S' unit is *supposidly* equal to 6 dB. 6

dB is an increase in power of four times.

As to peak and tune, I've seen both CBers and
hams make the same mistake if they had a

meter that could be switched between rf

output and plate current (admittedly, I am

going back a couple of years here ... make

that 3 decades LOL). In both cases, the poor

guys simply had the switch in the wrong

position and tried to "peak" the unit. They

peaked the plate current. In the case of the

CB, it was easy to retune and the rig

performed just fine; in the case of the ham, the
poor final looked like superman grabbed it with
a red-hot hand and squeezed. It really looked

like fingerprints and a thumb mark on the

glass where it got so hot that the atmospheric

pressure forced the *very* hot glass inwards

Jim - top posting so as not to get more

confused than I already am LOL

Thank you for the input. For the record, do you disagree or agree with
the statement "Peaking and tuning a four watt cb will not raise its S
unit"?
