Mark enjoyed visiting a van where AM
broadcast transmitters were on display. He remembers working
on transmitters like them not long ago.
The one on the left is a Collins 20V3 from the 1960's and the red
one in the back is a direct competitor. It is a Gates BC-1F
from the 1950's. Both were built to run 1000 watts on the 540
to 1600 KHz AM broadcast band. They have been converted to
amateur radio use in the 160 meter (1850 to 2000 KHz), 80 meter
(3600 to 4000 KHz), and 40 meter (7125 to 7300 KHz) bands. You
may hear one on the air on 3885 KHz some night.
Amateur radio is a federally licensed hobby. Learn more at:

Mark especially liked the forums on electronic kit building and
antenna design using computer modeling. There was also one on the
history of amateur radio in Great Britain. Very interesting.
Most sessions were sanding room only.
Some 400 volunteers are used to make the event a success each
year. |

Now here is an HT (handi-talkie) with a HUGE antenna.
It should talk a loooooonnng ways!

Some vehicles sported an awesome array of antennas. Many hams say,
"You can NEVER have too many antennas."

Then there was the latest.
Flex Radio
Systems was showing their software defined radios.
These transceivers are basic hardware with software to make them
a receiver and transmitter.
Hard to believe, but true! |

Gordon West WB6NOA was handing out certificates of achievement for
obtaining an amateur radio license from his
radio school.
You can't buy a license. Instead, you must earn one through
FCC examination.
In this case, the certificate was for Paula Persons W0HA, who
studied for exams with CD and book instruction from Gordon about ten
years ago.
Gordon also participates in Hamnation on Internet television.

Mark met with ARRL
President, Kay Craigie N3KN.
