KA0USA's Activities

I was first licensed as KE6DCE in September 1993 when
I passed my Technician Class test in Apple Valley, CA. My main
interest at that time was to keep in contact with Bill using a
2-meter handheld, which I still do today using that same Realistic HTX-202.
Bill and I founded the Pueblo West Amateur Radio Club
on August 15, 2009. The enthusiasm of the new group inspired me to
study for my General License.
In October 2009 I fell and broke my arm near the
shoulder. Not being able to do much, I found that the accident
provided a great opportunity for me to study for my upgrade.
I decided on a whim that when the ARRL 10 Meter
Contest was held in December I would try to make 10 contacts.
Conditions had been very poor on that band, and I had never used an
HF radio before. I used our portable rig, a Yaesu FT-897D set up on
the breakfast bar and a 10-meter dipole at 12'.
The 10-meter band was in very poor shape on Saturday,
with only an occasional signal making its way through the deep fades.
I checked the band throughout the day and made 8 contacts in CO, TX,
CA, OR and WA. About three hours before the contest ended on Sunday,
conditions improved. MS, FL, GA, AL, AR, LA, and two Brazilian
contacts were put in the log for a total of 32 contacts for the weekend.
I was hooked on HF now and more determined than ever
to get my General License. I passed the test on February 13, 2010.
Since I was now living in the Tenth Call Area, I
decided I should have a "0" call, and I had found that my
old call was not easily deciphered by other stations on SSB. I
received my Vanity Call on March 19, 2010.
I have been an ARRL member and Volunteer Examiner
since 2010. |

While I am still attempting to
work all the states, I especially enjoy making contacts with foreign
stations and am slowly working toward the ARRL's DXCC award. My bands
of choice are 17 & 15 meters when they are open, running 90 watts
on SSB. I also enjoy 10 meters where low power and low antennas still
work well.
I use paper QSL cards, LOTW, and eQSL (to AG Verified
stations on request). If you would like to have a printed QSL card
for a contact, please send your card with a BUSINESS
SIZE SASE, or QSL through the Bureau, as my cards are 4"
x 6" and will not fit in a standard size envelope.

Bill recently bought a radio for me. so now I have my
own! It is an ICOM IC-706MKIIG. I haven't used it much, but I'm
primarily working PSK31 with an occasional SSB contact. |
I'm proud of the performance from the tape measure
antenna yagi I built in 2010 as part of a club project geared toward
hidden transmitter hunting. I did most of the work myself, including
cutting the PVC pipe with a chop saw and tinning the driven
elements. The tape measure used for the elements was purchased for
$1.99 at Harbor Freight. Six muffler clamps were used to attach the
elements, rather than using screws to attach them to the PVC
fittings. The ends of each element were covered with electrical tape.
The PVC fittings are bolted to the boom, so the antenna may be broken
down for travel or storage.
The antenna shows good a front to back ratio and side
signal rejection. Signal readings from the Colorado Connection's
145.130 repeater showed an S9+20 db (the highest the meter will show
on our rig) with the antenna pointed at it, an S4 reading off the
back of the antenna, and S0 (just noise) off the side of the antenna.
The original space between the driven elements was
1". We did tweak the SWR just a bit by decreasing the distance
between the driven elements by 3/16", but as built, the antenna
was okay for use as a transmit antenna as well.
The length of the driven element could be shortened
just a bit more, but it is quite usable as is. The SWR at 144 MHz was
slightly over 1.3:1 at 144 MHz, less than 1.2:1 at 145.5 Megs, and
less than 1.7:1 at 148 MHz. Any further tuning will be done by
trimming the ends of each of the driven elements 1/16" at a
time. No adjustment was made to the 6" hairpin match made from
uninsulated #14 solid copper wire.
RG-58 was used to connect the antenna to an Realistic
(Radio Shack) HTX-202 handheld.
I decided to try out the yagi and see if I could hear
the International Space Station. After deciding the crew wasn't going
to make any voice contacts on 145.800 Mhz on the pass, I switched to
the ISS APRS frequency of 145.825 Mhz. By this time, the space
station was approaching its peak elevation. The antenna did much
better than expected. I was able to track the ISS right
down to the horizon on a handheld radio. Until it was down to about
10 degrees above the horizon, signals were at full scale. I was able
to track the station to within a few seconds of the posted Loss of
Signal (LOS).
Later, Bill added an MFJ-762 attenuator to the
antenna. This added up to 81 dB of attenuation, allowing me to get
closer to the transmitter before the handheld overloads.
In January 2011, Bill and I attended Quartzfest,
an annual gathering of amateur radio operators in the desert south
of Quartzsite, AZ. While there, I participated in a hidden
transmitter hunt. I found three of the four transmitters and was
within a few feet of the fourth when it was found. |
