No. 1: It was almost a half-century ago when I first
received the certificate to the left. I was 14 years old
(1959) and studying for my Novice ham license. My
shack was the attic of our home. It contained an old
Arvin shortwave radio along with various other repaired,
modified, or otherwise customized, bare-chassis radios.
My antennas were various end fed wires which ran from
the second floor window out to any, and all, back yard
trees, in every direction of the compass. Surprisingly,
Dad was very supportive of my hobby!
This cert was framed and displayed with pride on the
operating room wall.  

No. 2: This cert is an upgraded, redesigned replacement
version of the first. It went into a frame and on the wall,

This one looked more like a diploma ... or something very

No. 3: No longer "Shortwave" - now we were upgraded
to "

Ah, the pride of placing this on the wall along side the

"All Band" ... can you imagine!?

No. 4: The ultimate honor.
Later in the certification program, vanity call signs
became available. This certificate joined the previous
three, on the shack wall also, to express my passion and
involvement in this fascinating hobby.  
There is a very long and proud tradition of being certified as a Short Wave Monitor. This privilage was awarded to qualified SWLs who met all the basic equipment and
operational requirements and demonstrated their ability to monitor, log, and report (via QSL format) international shortwave stations. In the beginning, confirmation
QSL cards were required to qualify for certification. Subsequently, endorsements were available for the certificates.
