Interesting meter

Hi all,

I figured maybe one of you was, um, experienced enough to recognize this
meter and let me know what piece of equipment it came from. I found it
in a cache of old broadcast equipment, so it is possible it was part of
an old carrier current transmitter or some other such thing. This is
the link to the picture:

Re: Interesting meter

The first question that comes to mind is “How do we know that SWR stands for Standing Wave Ratio?”

Re: Interesting meter

Here's some distinct possibilities

#1. It was used in an instrument that monitored the water level of a fish pond.
SWR = Still Water Reading.

#2. Then again, it may have been a modern version of something to keep track of evil doers in the north as in:
SWR = Salem Witch Raids, but the company went out of business early since there wasn't much call for that in modern times since nobody cared.

#3. Monty Python may have used the tester to measure audience responses to:
SWR = Silly Walks Reaction.

#4 In Horse racing, it was a:
SWR = Saddle Weight Range, to monitor the thoroughbred's load.

#5 Of course, the Lone Ranger may have kept a watch on his bullet production with a:
SWR = Silver Working Reserve device at his mine.

Interesting but I have never seen one... I am curious as to what you learn about this.

Hmmmm...
If the needle centered is 1:1, then 1:4 (.25) is to the left of center and 4:1 (4) is to the right. ???? It is a ratio.

Looks like an SWR Balance Meter for an AN/SRT-14 MF/HF transmitter or
associated coupler/tuner:

Re: Interesting meter

A 100-watt output transmitter (with a 4-400 final!) and antenna tuner, in a 6-foot rack. Equivalent to the tx section of my K3. Talk about "battleship construction!"
Lots of knobs for those who complain that the K3 has too few.

Hi Drew,

Looks like like you nailed that one. The meter is clearly visible near the center of the rack. Before this OT thread is shut down, can you let us know what an "SWR Balance Meter" is?

I was an ET in the navy. We had a week of school on that rig. The drawers were on rollers and rolled out for maintenance, then tilted so you could get to the bottom. You had to reach back along the sides and press a release to get the drawer to tilt for maintenance. The only trouble was, the High Voltage was on a terminal strip next to the button. Woe be unto you if your fingers extended too far under the chassis!!

Re: Interesting meter

In reply to this post by ab2tc

Oh, I don't have any experience with that monster, but I believe the swr
balance is tuned as follows:

There are several SWR meter switch positions on the panel, say 10:1,
5:1, and 2:1. In the 10:1 position if the SWR is less than 10 the meter
will be in the green; if more than 10 it will be in the red. Once you
get it into the green you'd switch to the 5:1 position and again tune
for the green; then the same in the 2:1 position for minimum green
reading. Whew!

(Personally, I prefer to leave my own manual SWR meter on Reflected
Power. If there are less than a few watts reflected then good enough for
govt work, haha... No switching, calibrating, etc.)

Drew

It's around 500 watts above 2 (or 3 -- don't remember) MHz.
