Hello fellow DXers and Contesters!
Licensed since 1963, active in both domestic and international contests, and past President of the Yankee Clipper Contest Club, the largest contest club in the US.
Top picture is the current Single Op 2 Radio (SO2R) setup with the following equipment:
Icom 781 on left, K3 on the right
Left side: 80, 20, 10 M
Right side: 160, 40, 15 M
Mini Keyboards connected to two PC's that are networked together. N1MM software.
Center switch (white box mounted between keyboards) selects audio, center position splits audio left and right radios.
What is pictured below is the latest addition to the 40 M band - 3 element yagi on a 42 ft. boom and uses an old Cushcraft 402CD set of elements. The old 402CD Driven Element is now the Director and the Reflector has been lengthened for the greater spacing. The Driven Element of the 3 element yagi is 55 ft. long (mounted on the mast,1 M above the boom) and comes from the remains on an earlier 40 M project called the Vee-Yagi that was described in QST, 1998 by NW3Z and WA3FET. Turned out the DE dimensions in the QST article were wrong (too long) and therefore worked great at 6.9 MHz! Took all that down and used the DE for the new 3 el. (pictured). I shortened the element from 65 ft. to 55 ft by using a loading coil (and no capacity hats as used with the Cushcraft elements). Appears to be more efficient and very effective but I will let you be the judge of that.
Phase 2 of the 40 M antenna farm - convert the fixed 3 el. yagi (pointed at EU) on the 20 M tower into a switchable array by using stubs to convert the director to a reflector and reflector to a director (the use of two directors, stubs and relays that short/open the feed point of the parasitic elements) to give me 3 el. at EU and 3 el. to VK/ZL. This is an extension of the work done with the Vee Yagi system previously installed.
The full line up of antennas at K1RX includes the following:
3 Towers on site:
20 M Tower (6 M yagi, 20 M yagi, 40 M (fixed on EU) - now a 3 el. on a 42 ft. boom - picture shows the past version when it was
a 2 el. Cushcraft (21 ft.)
15 M Tower ( 6 el. 10, 6 el. 15, top antenna of 5 over 5 South, 6 el. SW)
40/10 M Tower (new 3 el. pictured) below this antenna is a 6 el. 20 fixed on EU,
5 over 5 over 5 on 10 M and the 4 el. KLM 40 M pointed south (not in picture)
Antennas at K1RX
160 M Inverted Vee @30 M
80 M 4 Square, elevated radial system, Comtek Switch Box
80 M 2 el. wire beam pointed South
40 M 3 el rotary at32 M (pictured)
40 M 4 el. KLM yagi at 18 M pointed South
40 M 3 el. Modified Cushcraft 402CD similar to rotary 3 el. but DE is a wire dipole at 25 M (located just below the upper 4 el. 20 M yagi) fixed on Europe (now being converted to a switchable 3 el. yagi NE/SW using two Cushcraft Driven Elements (402CD model)
20 M 4 el. rotary at 30 M
20 M 4 el fixed West at 18 M
20 M 6 el fixed Europe at 25 M (on 40 M tower, below 3 el. 40 pictured)
20 M 4 el. fixed South at 10 M
15 M 6 el. rotary at 30 M
15 M 6 el. fixed Southwest at 20 M
15 M 5 over 5 fixed South at 27 and 15 M
10 M 6 el. rotary at 32 M
10 M 5 over 5 over 5 at 27M (EU), 20M (Rotary)and 15 M (South)- middle 5 el. rotates 300 degrees
6 M 5 el. at 35 M (on 20 M tower, above upper 4 el. 20)
Icom, Yaesu, K3, Alpha equipment.
This station typically operates in the multi operator, multi transmitter category in the DX contests and Single Op, Two Radio when I play by myself.
Now very involved with the World Radiosport Team Competition that is coming to New England (W1 land) in 2014. Watch for info at http://www.wrtc2014.org/ for news here.
