Ham Member Lookups: 13209





I have been a ham operator continuously for 58 years


You can find me on the air on; at:

PSK-31 on 40M, 30M and 20M

SSB on 160M to 23CM especially 20M and 17M

Digital SSTV on 7173 KHz (40M) and 14166 KHz or 14233 KHz (20M).


If any of my pictures have red/cyan color fringes they are 3D Anaglyphs which I made. 

  They can be best seen with red plastic over the left eye, and cyan plastic over the right eye.


and Digital Panoramas










I was first licensed in Michigan as W8NSO in 1953, operating Novice CW, then 160 AM, 75 SSB, and 80 RTTY.


When I got married in 1966, I moved to Colorado and obtained my present call of W0LMD. I operate all bands from an actively and passively heated solar home that I designed,located at 9000' altitude near Conifer, Colorado, which is about 30 miles SW of Denver, Colorado

. I also designed and built two stairway lifts for the house. If you are ever out this way, stop by for an "eyeball QSO".

Satellite view of my qth


My HF rig is an ICOM 7700 running around 50 watts. The displays for the IC-7700 is a 46" HDTV showing Digipan 2.0 or EasyPAL and a pair of 19" LCDs.

A Quad Core 8.2 GHz PC runinig either Windos System7 or Ubuntu 10.10 runs the station

voice to text softwareshould be running soon, programed to either contol the staion or enter text.

An Icom 910 is used for VHF and UHF communiations.

An Alpha 77 2KW amplifier and a Henry 3K 1.5 KW amplifiier are currently being repaired by myself.. They are rarely needed.

Mobile and backup satellite rig is a Kenwood TS-2000X When on the mobile rig Irun 75 W on PSK-20M and SSB-17M

Antennas at W0LMD



I have several antenas available to me here on my 5 2/3 acre mountaintop.All of my antennas are built so that they come down to me, as I am at that age when climbing a tower is just not that much fun any more!

A 90' tiltover linear loaded vertical provides a very low angle of radiation on 160M,75M and 40M. This vertical has about 500' of barbed wire buried 6" below the surface for lightning protection and 4 above ground 1/4 wavelength long gull wing radials for each band provide a nearly perfect RF ground.

A Fan Dipole 270' long x 40' high provides a high angle of radiation local coverage on160M and 75M

4 elements on a 60' Rohn foldover tower - 2 elements on 40M & 2 elements on 17M, is pictured below. The picture was taken one day when the antenna was covered by a thick frost that makes the wires easier to see.

A 30M Dipole at 45' is my present antenna for this digital communication only band, but I hope to soon also have a pair of delta loops on 30M for improved signal to noise reception by eliminating multipath distortion.

4 elements - 20M on another motorized 60' Rohn foldover tower.This is my old fathfull antenna, modified considerablely to broadband it.

4 elements - 15M on a 50' Rohn foldover

4 element monobander on 10M is awaiting better band condx.

22 el circular polarized on 145 MHz and 40 el circular polarized, for LEO satellites on a motorized 45' aluminum foldover tower.

10' dish on automated ALTAZ mount, with a dual band patch feed for 1269MHz and 2401 MHz LEO and HEO satellites.

14' dish on a 10' high ROHN 45 automated ALTAZ tower with a triband patch feed for 435 MHz, 1269 MHz, and 2401 MHz awaiting the next good HEO amateur satellite

In process:

Remote Relay Steerable 4 Square Dual Band Vertical array for 40M & 30M. This will be a no compromise high efficiency dx array made from 24 - 2" x 3" x 10' sections of powder coated downspout. Each vertical has a 4" round copper ball (a toilet bowl float) at the top to discourge electrostatic discharges. Each of the vertical sections wil be shunt fed.

This array will use salvaged barbed wire fencing made from dual #12 wires with a pair of sharp barbs every 6", buried 6" below the surface, similar to the lightning grounding system used on my 90' 160M vertical. When (Notice that I do not say "IF") this antenna is struck by lightning, the barbs will arc directly to ground. Mountainous soil, unless wet, has extremely low conductivity. Gull wing 1/4 wavelength long above ground radials will be providing a very strong grounding path for RF..

My current cost estimate is $800 for everything. I wanted to test it out in this Winter's (2010) low noise DX conditions, but it looks like I will have to stop when the deep snow arrives soon. But I will have it all designed and modeled, even if i can't get it built as soon as I had hoped...

Pair of remotely steerable phased 40M dual Delta loop arrays are planned

All antennas are remotely tuned, steered, & selected outside.

Other activities that I do:

Designing and building tracking photovoltaic solar arrays.

Designing and building HDTV Antennas

Designing Vertiical AxisWind Turbines

Designing Low Head Kaplan Water Turbines for small streams.

And the latest project is an Intelligent Cane!


You may think that I am overly ambitious in all these projects. Well, you are correct in your view, but I was diagnosed with Parkingson Disease 9 years ago, yet I still do not shake. I have retrained my brain with an Anti-Shake. I am working within a new field called Brain Plasticity. It can be done, and. unlike Pills, MDs, and Hospitals, it is free for the most part, with few or no side affects. I am writing a book on How to Thrive in spite of various neurological disorders that mankind is afflicted with, such as PD, Altzeimers, Strokes, Chemo-Brain, ALS, Senior Moments, and PTSD.

My life has one rule now: "Its your Brain, Use it or Lose it."
