Here is another little quiz that should bring back some more fond memories for those of us who've been around a while, and let the more recent hams do some research that will help them understand some of the things that brought Ham Radio to where it is today. Submit your answers to the editor by April 15th and the top three respondents will get a mention in the May bulletin.

- Ross Hull is well known as a true pioneer of the VHF bands; instrumental in early development of the 5 metre band (before TV got those frequencies) and a little later on UHF (2 meters in those days). He died in 1938. What were the circumstances of his death?
- Now here's one that came up at the Inventors Club Breakfast on Saturday: Who became famous on the air for saying "No kids, no lids, no space cadets!"
- Morse Code was the only way to send signals in the early days of amateur radio. You may be surprised to learn that SOS was not the signal used by ships to indicate they were in distress. What was the first signal?
- "I think I'll open up an 807", would be a reference to what?
- In reality, what was an 807?
- Our fellow brothers over in "G" land had a different term for radio tubes than we did. What did they call them?
- The American Morse Code preceded the code amateurs use on the air today. It was primarily for wire circuits with sounders rather than a tone. What were the differences between it and the International Morse Code?
- The 6SN7 and the 6N7 tubes have identical electrical specifications. This was true for several other tubes with an 'S' in the second position. What did this S stand for?
- You either know the answer to this one or you'll have to search the back of old QSTs.
a) What's a D104.
b) There was a special version. What was special about it?
- Remember TV twin lead. Lots of us used it to feed open or folded dipole antennae. If you were short of cash you could make an SWR indicator to go with your feeder, from twin lead. Describe the two other items needed to make this indicator.
- In the days of spark transmitters, (before tubes) the incoming weak code signals had to be 'magnified' to operate some form of listening device. One method involved a small piece of glass tubing and a vibrator. What was this device called?
- On Oct. 5th, 1957 and for several days afterward what were hams all over the world listening to on 20.005 Mc? (that's Megacycles, which is what we had before Megahertz).
- Some old buildings appear to have 2 Metre verticals, with a glass ball in the center, spaced along their roof peak. a) What are these? b) Why did Ham operators try to keep their antenna below them?
- The Boy Scouts had three badges that led many young men into amateur radio. Name them.
- The first amateur microwave communication was accomplished on Nov. 15, 1945.
a) What was the frequency used?
b) What were the calls of the two Hams involved?
- What did Canadian Ted Rogers of CFRB fame contribute to Amateur Radio?
- Last month we asked what ARC stood for in a set of military radios. The SCR-522 set got a lot of hams onto the 2 Metre band. What did the SCR stand for?
- If one key part of your AM station was a Candle Stick, what were you referring to?
- Early loud speakers had 4 wires coming out of them. Two, of course, fed the voice coil, What did the other two wires do?
- What two Canadian coins
a) have Morse on them?
b)What is the Morse message?
That's it for April. Good Luck! I'd prefer that you didn't phone your answers in. If you don't have E-mail then do hand them to me at Mondays Club Meeting or send your answers by snail mail to:
