The crashed antenna on picture isn't 8x13wl. This was a brand new 16x7,7wl vertical group. This antenna never made a qso. The old 8x13wl is now at PA3CMCs QTH.

I have been first licensed on Jan.1,1951 under the same call I currently hold. Initially, my main interest was DXing on the HF bands; after gaining a certain amount of experience in electronics, I have become involved in activities on the higher bands, including EME (on 432 MHz) and microwaves (up to 24 GHz). I am also interested in 160m CW DXing, a very challenging mode. Present HF equipment: ICOM 756PROIII, Alpha 76PA, 3ele steppir @50 ft., inverted l (16 radials) and beverage for 160. On the higher bands: assorted gear and antennas for 50, 144, 432 MHz, and 1.2, 2.3, 5.7, 10 and 24 GHz. I have never been too happy with the "hello-goodbye" style of QSO, and would rather have at least a few minutes' conversation with my correspondent, language barrier permitting. Professionally, I graduated from medical school in 1956 and have been a practicing physician until my retirement in 2001.

Initially licensed in 1954 with a General class call of W3ZBE while living in Eastern Pennsylvania, then in 1959 with a Extra class call of K0RZJ while living in Kansas City Missouri, then in 1977 with the present call K0RZ while living in Boulder, Colorado. My Father who was my Elmer became a silent key in 1978, and held the calls of W3LCL and K0RZH. My Brother initially licensed as K3ALM now holds the call K0RZI.

The photo shows the K0RZ 432 EME antenna composed of 8 each K1FO 22 element Yagis. Each box of four Yagis can be manually rotated to either horizontal or vertical polarization in a few hours. The array is presently set for vertical polarization. The aluminum box in the center of the horizontal boom houses the Tx/Rx relays and the 0.3 NF preamp. Transmit power is 1500 Watts from an Eimac 8938. This system has been in use since 1991. CW is the preferred mode of operation.

432 & Above EME Newsletters

"I have been licensed since 1974 as WN3WMG then WA3WMG. In 1998 I changed to a vanity call K3MF. I am active on 432 MHz. EME using a Kenwood TS-2000x, a LZ2US amplifier producing about 1200 watts output to 8 x 25 K1FO yagis. My az/el control is a W2DRZ system with a homebrew az/el system. The az motor/gearbox is a 90 vdc motor running at 18 vdc for a slow and smooth rotation and the elevation motor( another 90 vdc motor) drives a modified jack screw that was once a truck jack. I use two preamps, one at the antenna and the other one at the rig. I am active on CW and JT65 modes and can take skeds as time allows."

  On the right is my small EME array for 2m and 70cm. The antennas are InnovAntennas G0KSC LFA's. There are currently 4 18 element 432 LFA's on the left of the H-Frame and 2 15 element LFA's on the right. Justin, G0KSC designed both the antennas as well as the H-Frame for the two bands. Thus, there are two 'Splitter Bars" which you might see in the picture. They are located attached to the horizontal H-Frame bar and mounted between the vertical mast and the respective vertical H-Frame leg. The splitter-bars allow mounting the phasing harness coax as close to the LFA feed-point as possible. This obviously reduces phasing harness feedline losses. The EME pre-amps mount on the splitter bars, at the splitter for each band. Thus they too are closer to the actual driven elements than found in other methods of feeding the yagis.

The AZ/EL rotator is a Polish SPID-RAS 1.0 degree accuracy. Sometimes you see them called AlphaSPID. The control box for them to work with the computer is their "Rot 2 Prog". The tower on the right side of the picture is a Glen Martin 40 foot "Hazer", (A tram-like cage carries all of the antennas up and down the tower with an easy geared winch-crank. So I needed a Az/EL rotator which would be able to fit between the edge of the tower while still allowing the "Mast" to ride in the center of the "Hazer". The SPID-RAS fits the bill. I have lowered this assembly in high winds with no trouble. The tower has three guy-wires which I unclip, at ground level, when I am going to "possibly" need "Elevation" greater than some high number. I just walk the circle around the tower and reach over and let the end of the guy wire drop from my hand to the ground. Might take 3 minutes to grasp and drop. I have had them dropped, so far, for 38 MPH gusts and there were no structural problems. The tower is an 18 inch base version.

Rig: K3 from Elecraft with 3 transverters: XV50, XV144, XV432 ; Xref board which allows my Trimble GPS to keep the K3 on a nearly exact frequency; TCXO's and matched 8-pole filters in all.

The view is similar to the one shown from circa 060 degrees around to 280 degrees and in the Southerly direction. This is what rural Appalachia looks like to us. There are no dwellings seen, or hidden in valleys, in this picture.

Other bands: 23cm 300W, 13cm 100W, +9cm 100W

History
First attempts were made in 1986 with very few qsos. The system has been under constant improvement ever since, and the current configuration is from 1997. The results in the ARRL EME contest have been around 150 qsos on 432 MHz.

Antenna
Paraboloid 16meters (55feet), f = 0,6. The mesh is normal chicken wire with 1" square ant the surface in accurate enough even on 1,2G. Look for the feed in QST, March - 88 p.12.

Feed
Normal 2-d. In the picture on the right side you will see the white box containing the relays and preamps. This designs have been in use concerning the preamp, and the normal system in use is MGF-1300 series device in cavity construction. Nf around 0,4dB. The whole feed system can be rotated between 0 to 90 degrees. It takes about 40 seconds, so there is possible room for improvement!
 
Aiming
The whole antenna turns on concrete turnable 0 to 360 degrees. Elevation is limited to +58 degrees, since that is enough in our northern latitude.
 
TX - N7ART - made with two 3CX800A7. Output about 1kW. Feedline is 22 meters 7/8" Andrew.
 
Control - VK3UM system with optical encoders. Resolution 0,1 degrees.
 
System G: Cassiopeia noise > 6dB4
