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.

1. I don't have your email... Haven't for a couple of years. Mine's
easy to find, if you know where to look. I've even been posting hints
as to how to find it for years.... every time I post.
2. I mostly operate on the Amateur bands now, though I do run 19 to
find out why I'm sitting in traffic, or to tell Swift he's a moron
(like he doesn't know already, but it's still fun to yell at the guy
who doesn't know how to keep it in his lane).
3. It wasn't voodoo.. Voodoo is expecting pushing over 100% modulation
to make the radio "louder" on the receiving radio.... I've said it
before, and I'll say it again.. 4 watts on one channel is alot louder
than 40 watts on all 40.

The voodoo comment wasn't in response to anything you wrote or posted.
It was in response to claiming one could raise the S units on a 4 watt
cb with a peak and tune.
Besides, I don't even use 4 watts, I use 3 most of the time.
You going to try and make this picnic thingy?


Try being the operative word. With my schedule, it's impossible to
tell if I'm going to be working after I deliver the freight I've
currently got, much less next year... going to try.
