Five of the six reasons we like our QTH at Kailua Beach:

The sixth reason is the super low angle of take off for propagation over the salt water!!!

 

FireCloud 40 NVIS portable/emergency antenna for inter-island communications.

I developed the FireCloud 40 with the great help of Rob KH6NX

X.  I used common 1 inch PVC 10 foot sections cut in half and joined in the middle- the bases are common sun umbrella weights full of sand with 1 1/4 inch pvc sleeves epoxy glued inside as receiver for the three vertical antenna supports.

The antenna is #18 insulated stranded copperweld ('slinky').  The antenna dimensions are as follows

Driven dipole 67' 9.5 inches 10 feet above the ground

Reflector is the same length 67' 9.5 inches 3 feet above the ground.

Feed impedence is about 10 ohms, so we decided to feed it with 400 ohm twin lead and use a balanced tuner (you can see it in its garbage bag protector above)

The antenna directs energy nearly straight up with a maximum gain of 5.9 dbi.

We have had consistant communications on the Hawaiian 40 meter afternoon net using 5watts QRP.  Receiving is awesome with most signals on the net 10 to 20+ db over 9.

I have been seeking an antenna solution that was portable and could be stowed easily in a garage or motorhome, and be simply  and quickly deployed.  The goal is to use this for regional communications at low power while boondocking and talking with other RV hams in the southwest when too far apart for direct vhf or repeater ops.  Hence cutting the 10 foot support masts in half.  Best 73s and good LX (local communications) 73 Daryl W7TAE and Rob KH6NX

CLUB CONTEST RESULTS:

2013---- CQ WW SSB 2013 MULTI-TWO Team submitted 12.6 million points using only six pieces of #14 copper wire for antennas. The Team operated KH6MB at the clubhouse station. The 20 meter 1/2 wave vertical is visible in this picture:

Tiff AH6S, Martin KH6MB, Mark WH7W, Kemo KH7U, Dan W0CN, Daryl W7TAE, Ken W0QO, Bev AH6NF, Eran WH6R

The team made over 7000 contacts in 48 hours including 75 on 160 meters in 9 zones all operating DXpedition style. The antennas were set up in a day.

2012: THE XTREME TEAM CQ WW 2012 GLOBAL WINNERS:

 

(above) The "Xtreme Team" Global Winners of the 2012 CQ WW SSB Xtreme Category. Sandwich Island Shortwave Club Operators (from foreground to background nominally right to left) Eran WH6R, Bev AH6NF, Martin KH6MB, Dan WH7Z, Mark WH7W, Daryl W7TAE and Tiff (Tom)AH6S. We are standing between the director and relfector of the 20 meter two element end fed vertical yagi. The station used the calll KH6MB in the new Extreme category.

2012 The Year of the TSUNAMI. The team operated 160-10 with home brew vertical antennas beachside, except for six hours when all Hawaiian beaches were evacuated in advance on the Saturday tsunami warning. Talk about extreme! No damage occured and we were back on the air to finishand ultimately win the entire category in the contest.

A close up of the vertical yagi 'pointing' 360 degrees over the pole:

CONGRATS TO THE SANDWICH ISLANDS SHORTWAVE CLUB FOR WINNING THE CQ WW SSB 2011 MULTI-SINGLE CATEGORY FOR OCEANIA OPERATING CALL SIGN KH6MB- SETTING A NEW MULTI-SINGLE RECORD FOR KH6 TOO! Just six pieces of #14 copper wire for contest antennas.

We are standing next to a 33' DK9SQ Kanga pole used to support the 10 15 and 20 meter half-wave wire monoband vertical antennas. Bigger antennas are hung from coconut trees next to the beach-yes the 40 and 80 half waves are really strung from trees by the beach. The 80 is in an inverted L shape with about 65 feet of vertical before the fold. The 160 meter is a 1/4 wave inverted L same as the 80 meter antenna.

PICTURE BELOW: The 2011 CQ WW SSB multi-single contest team. In the background are the 20 and 15 meter half wave verticals. We worked 160-10 meters with homebrew monoband wire verticals-lots of fun, and no beam headings to keep track of- contest call sign was KH6MB. Kailua Bay, Oahu in the background, behind that is the US Marine base.

Pictured are front row left to right: Bev AH6NF, Ken N0QO, Eran WH6R, Dan W0CN, back row left to right Martin KH6MB, Daryl W7TAE, and Tiff AH6S.

This team won Oceania CQ WW SSB Multi-Single and set a record in the category for Hawaii

Tah-dah...worth the wait.

When there is no DX we can catch some 'airtime' on the beach:

ABOUT: Sandwich Islands Shortwave Club was founded in 2008 for the general purposes of pursuing common interests including long distance shortwave communications, antenna experimentation, contesting, public service,education and portable operations. The Sandwich Islands was the name given to the Hawaiian Islands by Captain Cook in honor of his supporter the Earl of Sandwich- reputed inventor of the Sandwich. Our club favorite is of course is the ham sandwich.

CLUB STATION QTH: Primary club operations are from Kailua, Oahu, Hawaii. Kailua beach is a north facing beach on the eastern half of the island of Oahu about 20 miles NE of Honolulu airport.

RIG/ANTENNAS: Elecraft K3 transceiver, Acom 2000A running capable of 1500 watts down 150 feet of coax to half wave mono band verticals for 80-10 end fed with a home brew tuner designed by KH6MB. The 80 meter 1/2 wave is actual an inverted L shape, as is the 160 meter quarter wave vertical-Mics include Heil PR 781 and Heil BM-10 HC 5 headsets. Kent twin paddle key.

The call sign KH6TE represents an appreciation for American inventor Thomas Edison who once said: "Results! Why, man, I have gotten a lot of results. I know several thousand things that won't work."

Aloha and 73s
