April 1946 QST

articles are scanned and OCRed from old editions of the ARRL's QST magazine. Here is a list
of the QST articles I have already posted. All copyrights are hereby acknowledged.
At first I thought maybe this was intended to be
an April Fools joke, being that it appeared in an Aril issue of QST, but it is probably just a coincidence. One of the two
topics refers to a 'door knob for UHF,' which in reality was a glass-encased vacuum tube that was shaped a lot like one
of the old glass door knobs. The author penned a humorous take-off. On second thought, maybe this is a Fool's edition now
that I have read the second item. All kidding aside, "Strays" concludes with a poem dedicated to those who became 'Silent
Keys' as a result of World War II.
Having heard and read much
about the famous "door knob" for u.h.f., we decided to try it. We removed the knob from our door and substituted it for
the HY75 in our pet oscillator. Vast improvements were immediately noted, among which were:
1) Remarkable lack of spurious radiations such as sidebands, parasitics, and harmonics.
2) Stability under modulation.
3) Constant power output and stability over the entire tuning range.
4) No overheating of the doorknob even under heavy load.
5) Circuit constants not critical for normal operation - therefore likely to give same results even for beginners.
Before you try it, however, make sure your power supply can take it, as the power consumption is rather excessive. The
theory of operation is beyond the scope of this paper. Suffice it to say that by Judicious use of relativity theory, calculus
of variations, and advanced buggering we became convinced that this apparatus was the most sensible way of going insane
since the invention of the regenerative receiver.

Connecting-wires in radio
receivers are eliminated by a method announced recently. Bare metal sprayed into channels in a plastic chassis is the basis
for the method which, it is said, speeds production, reduces operating costs, permits lower prices and improves performance
of radio receivers. The process has been used in other countries, particularly Germany, where in wartime the spray method
was used in the fabrication of radio coils.
How sweetly sleep the Silent Keys!
How proudly wear the Golden Star,
Who gave their lives beyond the seas
In the red hell of war.
They heard the challenge to the right
By which all free men seek to live;
They knew the cost to win the fight,
The price that they should give.
Yet went they forth from hill and plain,
From friendly cities of their birth,
To bring goodwill and peace again
To all the ravished earth.
And now they sleep in foreign fields
Beneath the crosses and the stars;
With memory's tears alone the yields,
And Silent Keys and Stars.
O soldiers, sailors, home again,
Prevent these endless wars
Where right survives by blood and pain,
By Silent Keys and Stars,
- Lt. Comdr. Robert D. Bass, W4CQG-W3JSI
