Total number of logged contacts was 698 QSOs.  We worked a few on more than once  on multiple bands during alternate operating sessions.

The power switch is located on the West wall.  The box (actually a pill bottle) to control TX switching of the amplifier has been built to link it to the Yaesu transmitter.

QSLs from Nat’l Wildlife Refuge Week

We received two QSL cards in the mail from when we ran our special event station for National Wildlife Refuge Week.  We operated our special event on October 11, in the field by the Tennessee River, to celebrate the Wheeler National Wildlife Refuge.  Part of the Refuge extents in to the Arsenal and the NASA Marshall Center.

KA5VZG in Tennessee, in particular, wrote to thank us for activating Wheeler National Wildlife Refuge.  He showed us on his card that he is a retired US Fish & Wildlife Service Refuge Manager.

Our other card came from N1INI in Uxbridge, Massachusetts.  His card shows a photo of the Cape Naddick Lighthouse in Maine.


Here are some more QSL cards we received for the special event, through eQSL.  N1INI sent us a different photo in this set.

CQ World Wide DX SSB Contest 2015

We participated in the CQ World Wide DX SSB Contest last weekend from the station.  I (WA2JQZ) came at the start on Friday evening (Oct. 24 00:00 UTC) and operated a few hours on 15, 20, and 40 meters.  15 meters was wide open to the Pacific in the early evening.  I heard DU7JAY in the Philippines and AH0K in the Mariana Islands.  But the propagation shifted before I had a chance to reach them.  I did work many Japanese stations.  Then I shifted to 20 and 40 meters, and worked stations in Europe and Latin America.  I heard a station each in Kuwait and Bahrain, but the wait seemed long and I moved on.  I spent time to get a few QSOs on 40 meters, as I figured we would not be able to use the lower frequency bands on Saturday during the day.  On 15 and 20 meters I used our new HyGain TH-11-DX directional antenna.  For 40 meters I used our 40 meter dipole.

Rob KB5EZ came at noon on Saturday and operated a couple of hours on 10 and 15 meters, also using the TH-11-DX.  For the first hour and a half, he pointed the antenna towards Europe, working Europe, Canada, and some of Africa including D4Z in Cape Verde.  He kept hearing South American stations on the side, and so for the next half hour turned the antenna towards them and worked them.

Matt KA0S and I came around 2 pm.  We took turns working more of 10, 15, and 20 meters.  During the afternoon, 10 meters was open just to Latin America and Canada.  15  also gave us Europe, plus KL7RA in Alaska.  And 20 meters gave us more of Europe too.  We heard several French island special event stations, but offhand didn’t know exactly where they were, except for their CQ Zone information.  Matt was able to look up a couple on his smartphone: TO4K was on St Barthelemy Island in the Caribbean (southeast of St. Martin), TO2M was in Martinique. Matt worked some countries that we usually only hear during contests: Luxemburg LX7I , Morocco: CN2AA CN2R CN3A, Barbados 8P5A, and Peru OA4SS.

I came back to the mike later in the evening.  10 meters opened to the Pacific: I worked many Japanese stations with some Australian and Canadian stations.  And on 10 meters I finally worked AH0K.  Then I switched to 15 meters.  I no longer heard western Europe. But I did work again many stations in Japan, plus more in Australia, in Hawaii, four in New Zealand, a few in Asiatic Russia, and one in Kazakhstan UP2L. And I worked AH0K again, AH2R in Guam, and after a lot of patience, V73D, a German DXpedition in the Marshall Islands.  I finished by getting a few QSOs on 80 meters as that band started to open to DX.  Then I was ready to go home.

By the end we worked 297 international stations, located in 55 countries and territories.  We earned over 200 multipliers, and claimed a score of about 168,000, in the “Multi-Operator, Single Transmitter, Low Power” category.  I believe we all had fun.  The new beam antenna was definitely an asset.  I think it made a difference in reaching some stati0ns, including to Latin American, the Pacific, and Asiatic Russia.

National Wildlife Refuge Week Special Event, October 11, 2015


This post is our update to our Special Events page. Photos by KB5EZ and NM4T. Text by WA2JQZ.

Operation Date: Sunday October 11, 2015
(National Wildlife Refuge Week was October 11 – 17, 2015.)
Time: 1400 – 1900 UTC (0900 – 1400 CDT).
Location: Easter Posey #2 Recreation Area, Shields Road, Redstone Arsenal / NASA MSFC.

NN4SA operated a special event station to celebrate National Wildlife Refuge Week. Parts of the NASA Marshall Space Flight Center and Redstone Arsenal are in the Wheeler National Wildlife Refuge. Our club station Bldg. 4622 is located just a few hundred feet from the wildlife area boundary. To keep close in spirit, we set up and operated a portable station at the Easter Posey #2 Recreation Area. The recreation area is at the southwest corner of the Arsenal, by the Tennessee River, and also is near the wildlife area boundary.

The Wheeler Refuge was established in 1938 by President Franklin D. Roosevelt as a haven and breeding sanctuary for migratory birds and other wildlife. It is 35,000 acres of mixed habitat, located along the Tennessee River in north Alabama.

We were on SSB and RTTY with a primary 100 W HF station, on 15, 20 and 40 meters. We also operated a CW QRP 5 W HF station on 20 meters, to participate in the QRP ARCI Fall QSO Party. Each radio used EndFedz wire antennas suspended from the trees. Although band conditions were poor, we made about 40 contacts, including 4 RTTY and 8 CW QRP. We also joined in the Arizona and Pennsylvania QSO Parties. A few contacts resulted in ragchews, on phone and CW. We made several DX contacts: to Italy, to Croatia, and to the Canary Islands. This was a relatively relaxed special event for us. We had hot apple cider at the start in the cool morning, and we made a lunch break with fresh grilled hot dogs and accompaniments. Our operators were KB5EZ, NM4T, WA2JQZ, and N4MSN.
