Electro-metrics NTR-51C
Nontunable Receiver

If you have never seen one of these before, You may be asking yourself " Who the h--l needs a receiver that you CAN'T TUNE?? "
Well, before you write this off as another government boondoggle, just take a minute and FEAST YOUR EYES on THIS
beauty.

HMMM...look at all those FILTERS...


Starting at the lower left end, you've got a bunch of LOW PASS filters.
They let you select from 200 kHz to 1 GHz in what looks like a
nice 1-2-5 sequence. This could be the top end of your pass band, I guess..

Now look at the next row above it.
It looks like the same thing, only HIGH PASS...
HEY NEAT-O...You could carve out almost any portion of the radio frequency spectrum, starting as low as 200 kHz
or as high as 500 MHz and then ending anywhere* (* well, ALMOST anywhere..) from 200 kHz to 1 GHz. Then you can look at this chunk of the spectrum ALL AT ONCE, without having to diddle with tuning knobs and stuff..

And think of this: by doing it this way your measurements will always be ONE HUNDRED PERCENT REPEATABLE.

Now, think of what you could do once you get on the air with this thing. Specially if you have one of our Uniquely Designed ANTENNAS

Wanna play with one before you buy it? This can be arranged. Come over to our Lab (bring money.)

GOING BACK TO THE PICTURE OF THE NTR-51C Now, what's this stuff on the lower Right end..."special filters.."
( You always have to watch out when the government calls something "special")

HMMM. There's two extra HIGH PASS filters, a 5 kHz one and a 100 kHz one..

It looks like you could start your passband way down at FIVE kHz instead of at TWO HUNDRED kHz.. (sweet!! ) Now, looking clockwise from the TOP LEFT, lesssee..weve got: *a handy little attenuator, * some pre-and post amplifiers ( to reduce the interaction between the filters and clean up the signal) * a couple of more adjustable high and low pass filters.

And hey, you could also end your passband at THIRTY MHz.
Now WHY WOULD ANYONE WANT TO DO THAT??
what is so special about 30 MHz? If you don't know, look it up before your boss finds out.

THE RAYTHEON 1150 general-purpose receiver: This is one of the most rugged, reliable, practical, and easy to use receivers ever made.
it tunes from 100 Hz to 1 GHz, with EIGHTEEN SELECTABLE BANDWIDTHS:
50 Hz, 100 Hz, 200 Hz, 500 Hz, 1 kHz, 2 kHz, 5 kHz, 10 kHz, 20 kHz, 50 kHz, 100kHz, 200kHz, 500 kHz, 1 MHz, 2 MHz, 5 MHz, 10 MHz, and 20 MHz, all readily available at the turn of a single knob SEE PHOTO.
This 1970's era receiver is truly a joy to work with.
.I am only offering it because we need more room in our lab. This beauty comes with a VERY readable, well written and detailed OPERATION AND REPAIR MANUAL, which is NOT available separately, nor anywhere else in the world as far as I know (I checked).
At no extra charge, you get a SECOND, somewhat beaten up, Raytheon 1150 to play with and use for parts.

If you have to ask what these are, you probably don't need one.
( Or you might actually need one A LOT, and you don't even realize it. THEN YOU'RE IN TROUBLE!)

THE STODDART 533 SYSTEM


Now, here are some nice receivers. they are LIGHT, RUGGED, AND EASY TO FIX! EASY TO OPERATE TOO.When your boss sends you humping around the world on another " Mission Almost Impossible " you'll be glad you had these with you.

P.S.:Don't forget to buy the 533 x-11 too. You dont have to have it, but you'll be glad you took it along.
Your wife will be glad too, when you get home a few days early.

THE WATKINS-JOHNSON 125 SYSTEMS:

Now the following *WATKINS- JOHNSON (WJ) systems may not be elegant, but they WORK. They may be big, heavy and ugly but they are also VERSATILE. You can do MANY UNIQUE THINGS wth them.

And talk about EASY TO FIX!----------------> Look, they are MODULAR!

This means that if you blow a tuner or a demodulator in the middle of a hot project on Christmas Eve, you don't have to shut down the lab while you send your precious receiver to California to be psycho-analyzed. You keep a few (wisely chosen) extra tuners and demods around, slap one in, and you are back up on the air in 15 minutes! ==========================================================================================
