Twist:

Actually, there is a correlation. If two radios

are set up in a "fixed" location, each, and one

transmits a carrier, there will be a reading on

the "s" meter of the receiving radio. Assuming

the two radios are far enough apart so that the
transmitted signal does not register above,

say, s5 on the receiver, it is possible to get a

relative power reading from the transmitting

radio. Now if the transmitting radio increases

power fourfold, say from 4 watts to 16 watts,

the receiving radio should now show s6 on its

meter.

This of course assumes that the receiving

radio's ALC is tuned properly and that the

s-meter is calibrated properly. In a properly

calibrated receiver, a 3db increase in received
signal strength should show about 1/2 of an S

unit. Doubling the power output is the

equivalent a 3db increase.

Whooa...you sure?

It's a moot point, but output power does

indeed have something to do with "s" units, to

the receiving radio. There isn't a direct

correlation, and most CB receivers probably

aren't calibrated properly, but there is a

correlation, nonetheless.

Yes, thanks for the reminder. I am aware output has much to do with the
S units on the receiving end.
What was being discussed was a peak and tune of a four watt radio. No
amount of tuning or peaking is going to render a difference in S units
from 4 watts.

To the original poster: as for the antenna

advice, a Wilson 1000 is a decent antenna,

and will do fine. You will notice increased

receive and transmit range while still

remaining legal.

Hope this helps.

SSB,,Im taking another road trip to the Carolinas real soon,,probably
Myrtle Beach. In addition to seeing if Dwight wants to hang out awhile
(I may have to drive to Surfside Beach, for that) you have to send me an
email letting me know your times and freqs of operation. I'll try and
hollah at ya' from the road.
