Popular Misconceptions.
 

Everything appears quiet on the Western Front. So let's waken things
up.

Is there anybody about who still imagines that an SWR meter, located
in the transmitter, or even on the other side of the tuner, indicates
SWR on the transmission line between transmitter and the antenna?

Yes, Reg, I know there are some morons out there who believe that.
Let's see who wakes up with this.

If it's a stand-alone SWR meter with three foot 50 ohm
coax cables on the input and output, then it is located
in a 50 ohm environment and is indeed indicating the correct
SWR. The thing that makes an SWR meter indicate a valid value
is if its physical environment is extensive enough to force
the impedance ratio of Vfor/Ifor = Vref/Iref = 50 ohms.

Back when I got my first license, those things were called
transmatches. Seems you would like that name better than
SWR meter. TRANSmitter MATCHing device = Transmatch.

Hello again Walt, I trust you are well.

I wouldn't go so far as listing them as morons. Just unfortunates who
have been afflicted by the plagiarist outpourings of old wives who are
still in the 1950's

A long thread is not expected. People are reluctant to admit past
beliefs. I was just testing the present situation. But you never can
tell, people may write in just to disprove my expectations. There's
much to be learned in addition to mere SWR.

Yours, Reg.

Cecil your argument begins with a big "If".

If only pigs could fly!

Nevertherless I agree with your name Transmatch. As you already know,
I myself advocate renaming the SWR meter as a TLI - Transmitter
Loading Indicator - which is what it actually is.

By no stretch of the imagination is it a Standing Wave Meter.

An SWR meter is no different from any other piece of
measuring equipment. One shouldn't use a DC ohm-meter
to measure RF impedance. One shouldn't use an SWR meter
designed for a Z0=50 ohm environment in an environment
where Z0 is unknown or non-existant.

Earlier, I didn't mean to imply that the SWR meter was
known as a Transmatch. It was the entire antenna tuner
that was (and still is) known as a Transmatch.

Hi, Reg:

Reading the mail, I assert that your unsnipped statement has been **quite**
literally accepted, and applied, by many imaginations.

It is akin to writing, eg, that "Mr Churchill spared nothing to win WWII."

Why is there a formula to quantify reflected power from an SWR reading? I
have been using SWR meters all my life to check on reflected power from the
antenna. This simple act has worked very very well for me through the years.
I did this in my younger days professionaly for Raytheon. When I had tuned
the antenna tuner or the antenna itself for a 1:1 match, suddenly I have a
system that talks a long way. What was wrong with that?

In all seriousness, Reg, don't you think it would be better to be a
bit more clear about what you mean by the "other side of the tuner".
So far as I'm concerned, until I know what side of the tuner to which
you refer, I wouldn't want to comment.

Reg,

Instead of yet another posting on the topic beyond the 20 or so you've
already blessed us with proposing the new TLA (three letter acronym) of
TLI, why don't you start by contacting Agilent (formerly HP), Narda,
Anritsu, and the other manufacturers of precision terminators? Surely
those professionals will see the impeccable logic of your proposal, and
will immediately cease publishing a maximum SWR specification for their
terminators. Then the manufacturers of RF transistors, directional
couplers, attenuators, and other RF devices, which now have input SWR
specifications, will follow. Of course, they can't call the former SWR
the TLI, since it's not indicating anything, and there's not necessarily
a transmitter involved. And the whole object here is to be consistent
and rational, after all. So how about "RER" for "Reg Edwards Ratio", as
in "guaranteed maximum RER = 1.1"? No one should confuse that with
anything else.

Wouldn't this be a wonderful world (AWW) if only we were always strictly
logical (ASL)?
