Personally, not really. My voice sounds best through one of those old
Johnson crystal mics. My favorite is the Turner 333.

Too bad you don't like the extreme heat.



I don't mind the heat -- it's the humidity that sucks.


One or another of the many
stations here are always hiring, but then again, the doors are revolving
types mostly at Clear Channel or the other scumbags and they own it all.
We have one community radio station that has lasted over the years on
donations and fundraisers. Tough to hold out when you're independent.



Yeah, at HP I got a peek at a full-blown cost-benefit analysis showing
increased profits by increasing the employee turnover rate. And to
think there are some people who think labor unions are obsolete.....

I don't see anything about a 5:1 SWR.

I don't see anything about being "forced" to use a matching device.

Now is a good time to dispell more CB mythology: Many of you already
know that in order to double your range you need -four- times the
power. But it also works the other way -- if you reduce your power to
one fourth (i.e, you are losing 3/4 of your power, which would mean a
pretty high SWR) you have -only- decreased your range by one half. So
an SWR of 2:1 or 3:1 (or, conversely, squeezing a couple extra watts
with a tweak-n-peak) isn't going to have a noticable effect on your
range.

Let's continue with the scenario that you are losing 3 watts (3/4 of
your power) due purely to reflection. Ok, so that power gets dumped
back into the final where it's dissipated as heat. That's three extra
watts in a transistor conservatively rated to handle a certain amount
of -continuous- heat dissipation, which is usually something along the
lines of 4 watts. Mind you that 3 or 4 watts isn't a whole lot of
power; if the heat sink can handle 4 watts without a problem then an
extra 3 watts isn't exactly going to melt the knobs. Regardless, the
final -isn't- dissipating this heat continuously (unless the OP is one
of those asshole broadcast types that keys down for half an hour), so
normal operation certainly isn't going to "cook" the transistor. And I
already mentioned that these transistors are rated to handle 30:1 SWR
-continuously- without damage.

If you want proof of these FACTS then feel free to refer to the data
sheets for the final transistors most commonly used in CB finals.

Looks to me like he said the trucks already have antennas installed.
Assuming they are CB antennas, it's more than likely that the antennas
have already been trimmed for use with a 50-ohm radio (since all CB
radios are 50-ohm radios). Unless something is broke, the antennas are
probably going to give a reasonably good match to -whatever- radio he

What I -do- see is concern about setting the SWR, which is another
mythconception (and not just with CBers but with a lot of hams). A 1:1
SWR does -NOT- mean the antenna is operating at it's best efficiency.
It -DOES- mean that the load is 50 ohms nonreactive. But a 50 ohm
nonreactive load can be darn near anything: a carbon resistor, a dummy
load, a bad coax working as a tuned stub, or even a corroded 9' whip
with a mount caked in mud (seen both scenarios firsthand).

As I stated before, an SWR meter is a go/no-go meter. If it normally
reads 2:1 then suddenly jumps to 6:1, that's a good indication that
something has gone wrong with the antenna or coax. And -THAT'S- what
an SWR meter is good for..... a "something's wrong" meter (IMO, they
should probably be replaced with idiot lights like those in a car.)

If you want to tune your antenna for best efficiency you -NEED- to use
a field strenght meter. Period.


Now........ once again........

1) Where did the original poster say he was being "forced" to use any
type of matching device?

2) Where did the original poster say his SWR was 5:1?

3) Since very few CBers use a matchbox, why don't the millions of
other CB radios have blown finals?

I'll try this one more time. You will need to focus -REALLY- hard
because this is probably going to be explained on a temporal level
with which you are unfamiliar: logic. Are you ready? Ok, here we
go.....


Fact: Somebody already installed the antennas and coax in the trucks.

Fact: Most people who install antenna systems adjust them for the best
impedance match to their radios.

Now just in case you are worried about the word "most", here are a
couple things to consider: If the antennas and coax are -not- adjusted
for a very good match then the other drivers of these trucks would
have blown -their- finals already (according to your "truth") and
would have either complained or fixed the problem. And since a company
owns the trucks, the antennas and the coax, and apparently wants the
drivers to use CB radios while driving, it's very likely that the
company checked the antenna systems so as to make sure they actually
work and not blow up the drivers' radios. This seems plausible because
if company equipment is defective they could be liable for the cost to
repair or replace the driver's CB radio. Even in a worst-case scenario
where the antenna systems were defective and blew up CB radios all the
time, not only is there something fundamentally wrong with the antenna
systems that no matchbox is going to fix, but someone is bound to warn
him that he should -not- plug his radio into the truck's antenna. So
in all probability.....

Conclusion: The antenna systems on these trucks have been adjusted for
the best impedance match to a CB radio.


Now hold on tight because this is where it all comes together.....


Fact: All CB radios are designed for a load impedance of 50 ohms. From
this fact you can draw two conclusions:

Conclusion #1: A CB radio with a load impedance of 50 ohms was used to
adjust the antenna systems in the trucks for the best impedance match.

Conclusion #2: Any CB radio the original poster uses is going to have
a load impedance of 50 ohms.

And those two conclusions lead to one FINAL conclusion: The antennas
and coax are -already- adjusted for the best impedance match to -any-
CB radio the original poster might use.


Bottom line: He's not going to blow up his radio if he doesn't use a
matchbox.


Now feel free to go back to your troll routine of calling me a "fool",
an "idiot", a "ma'roon" and a "brain-dead whacko", because you just
earned your place in the killfile.

Frank... the point you're missing is that although it's like you say
"All CB radios are designed for a load impedance of 50 ohms."... there
are certainly different reactances (j factor) from radio to radio. No
radio or antenna is exactly 50 +j0. This is where the matchbox can help
to supply the conjugate needed for maximum performance.

SWR alone will not destroy a bipolar transistor unless it is operated
outside the Safe Operating Area. The weakest part of a bipolar
transistor is the base emitter junction. Abuse that juntion and the
transistor will not forgive you.

I would venture to say that nearly all CBs on the market if operated
at the legal power levels and within voltage and currnet levels will
handle SWRs well beyond 10:1. At those SWR levels, one will definitely
know that something is wrong with a remarked lost of receive signals.

*******

Up to about 3:1 the loss in range is minimally discernable. After 3:1
you will notice some loss of receive in weak signals and some gradual
worseing of transmitt range as SWR get higher. This is due to less and
less power delivered to the antenna for radiation.

As for hurting the radio, if you haven't overly modified the original
design or operating the radio outside the specifications that it was
designed for, No. Disconnect the coax from the radio will do more
damage than a poor SWR.

Yep with protable pensionplans they don't have to contribute a much to
them and that is a big savings there.

I think the ghost of Adrew Carnegie is walking the halls of many
businesses to day. Whispering into CEOs ears saying contrtol costs and
profits will increase.

If we take the equation 50 + j0 ohms to be a 50 Ohm impedance then an
equation in this form, x + jy, will yield an infinite solution of
equatins where the magnitude of the impedance is 50 ohms.

Conversely 50 + j50 Ohms is not 50 Ohms impedance.

What does vary from radio to radio is the tuning of the output filter
and matching network. Still this variation is not much greater than
about 5%. That 5% variation will not alter the match between the radio
and the coax significantly.

Finally, SWR is not determined by the mismatch of the radio to the
coax. SWR is determined by the mismatch of impedance of the antenna to
that of the coax. SO variations of source mismatch play a relatively
small degradation in the system performance.

Since CB radios are calibrated at the factory to a 50 ohm nonreactive
dummy load, I find it highly unlikely that a CB radio is going to have
any significant reactance or variation from the designated impedance.

Now look up the word "conjugate" before you misuse it again.

It's dirty pool, and a very common practice. The big thing is the medical
and retirement insurance. The FICA and SS payments are an after thought,
when deciding some devoted guys fate. :(

Another easy way to quickly cut though all this BS, call up dealers,
manufacturers and ask them if it will void the warranty if you consistently
operate the rig into greater than a 3:1 SWR.

No reason to take the words of CB Dummies, ask the people who have to repair,
replace and maintain the equip. Their word is the word of "God." Or else, you
back it up with your pocketbook.

Hi,
If I'm not able to set the SWR in the trucks that I drive will it hurt the
radio or just give me decreased range?

Well you or I might be able to advise him about the things he shouldn't do,
but that takes some of the fun out of it.

I'd ask you for advice if something HF/RF had me stumped, and I'd likely
get some good advice, if you weren't ****ed at me! (j/k)

I am a fan of the truth and logic. whats wrong with that? I read the other responses but they make no
sense but Franks does because it is well thought.


Scott in Baltimore August 3rd 05 08:18 AM

I have to agree with you Frank. This 'John' comes on this board
denigrating CBer's and is now a know all see all.


"John Smith" made it to my ignore list. When I reach one of "his" posts,
I change to sort by user and click all the dots next to that name.
I then switch back to thread view. There are a few others that deserve
this treatment as well. It cuts back the clutter in my newsreader!
