Our first luncheon get-together
of 2003 was held on Saturday, January 18th at the historic Redings Mill
Inn, south of Joplin, Missouri. We had 18 folks and one junior operator
attending lunch today. There may have been snow on the ground outside,
but we had fun inside!

The word about the 4SQRP Group must
be spreading as we had several "first timers" this month. We enjoyed
visiting with you today and wish to thank you for joining our group. Hope
you can participate often in 4SQRP activities.

John
WØJRP and Betty Jo from Joplin attended their first FSQRP luncheon
get-together today.
|
John WØJRP
uses this homebrew tube type QRP transmitter. It uses a 6AQ5
on 40 meters.
|
Joe Porter, WØMQY demonstrated a 20 meter
loop antenna that he has been working on. He has made several QRP contacts from
inside his house using this loop. The antenna uses a motorized variable tuning
capacitor to resonate the loop with very sharp tuning. The motor and gear assembly
was salvaged from an old copy machine.

A closer look at the loop's motorized
tuning system.
|
The loop is 33 inches in diameter and is mounted
on a stand built from PVC pipe. In the photos, a gamma match is used to feed
the loop. After the meeting, Joe reported that he changed the feed method to
a Faraday shielded inductive coupling loop 6.5 inches in diameter made from
9913 coax.

Here is a view of the gamma matching
assembly on Joe's loop.

Thomas KCØAUU is at the
far end of the table with Nancy NØFNZ in the right corner. Pete
Banfield is on the left (black ball cap) and Ira KD5AUX is wearing the
yellow cap.
|
Larry Sparks NØBHU is building a low power
AM transmitter for 75 meters. It's not too often we see a transmitter with a
big audio chip and a modulation transformer.
|
|
|
|
Here is Larry NØBHU's
75 meter AM transmitter. The heat sink on the right rear is for the modulator
and the final PA is on the left front. He is getting about 9 watts of
carrier power output.
|
Larry also built
this nice double paddle. There is a pivot for each paddle arm and there
is a tension spring between the arms.

Getting ready for lunch. Rowena
and Rex KC5UVN from Tulsa, Oklahoma are on the left front.

Layne
WDØDDU and Joe WØMQY show us their lunch. Good thing they
ordered the "small" sandwich! Jim WBØIYC is passing the
ketchup.

Today we had a "white elephant"
door prize drawing. The white elephants were various bit and pieces of unknown
quality scavenged from the dark recesses of many ham shacks (and maybe a few
dumpsters). Actually, several really nice parts found new homes. Also John,
WØJRP shared many vintage issues of 73 magazine dating from the 60's
and 70's. Thanks for the historic reading material John.
In addition, Jay KØETC passed
out brand new two-circuit mini phone jacks to everyone for our building enjoyment.
Thanks Jay!

Next month will be the judging of
the Builders Contest on February 15th at a location to be announced. Watch
the 4SQRP web site for more information. Let's hope for good weather and clear
roads. See you then!
