I started out in 1971 building my first Heathkit Shortwave receiver when I was 11 years old, got my WN2QHN novice call on my 13th birthday in 1973. Was inactive from 1977 - 2001, and then got into DX-ing.
My antenna system is an N6BT DXU-32 - 3 elements on 20 and 2 on 40M on a 28 foot boom. Amazing antenna. I have a 30M Extended Double Zepp that also works as a hatted "Tee Vertical" on 160M and a doublet on 30, 15, 12 and 10M.
This is my "Tee / EDZ / Doublet" remote switching arrangement:
Here is the circuit:
It is resonant on 30M in the doublet (EDZ configuration) and in the "Tee" configuration, resonant on 160M with this "FCP" (K2AV Folded Counter Poise) and tied into 140 buried radials underneath:
With the ACOM 1500's built in tuner that can match an SWR of 3:1 or lower, this means I have resonant antennas on 160 - 10M. I also have a 17M Moxon up 36'.
I am helping with the Heard Island DX-pedition - for news and information, please visit:
I was stuck at 325 entities for a while, so sought out Dean Straw, N6BV's HFTA program. HFTA most definately got me over the hump because it told me why I seemed to miss the ATNO's that I needed for Honor Roll. Here is the affect that these hills have had on my DXCC experience. You can see why anything in the NE direction would end up being ESP - for any DX that required a low take off angle:
The graph was produced by running my HFTA data files through Stu, K6TU's program that then visualizes that data in a 360 degree azimuthal plain. Here is the shack:
The K3 and ACOM 1500 make up the core station, and the Array Solutions Ratpack and my own "Tee-Doublet" switch handles the antenna switching chores. I use Astron Linear power supplies. I plan of taking the Ten Tec 238 and turning it into a remote auto-tuner, using wireless and Arduino boards - just for fun. My backup rig is the Ten Tec Eagle, and I play with the Ten Tec Patriot and other Arduino stuff.
I have a blog about ham radio, cycling and art at http://ky6r.wordpress.com I have presented at Pacificon for more than 10 years - and some of my past presentations are posted on the East Bay Amateur Radio Club's web site:
You can see that designing, building and playing with antennas and propagation modeling using HFTA consumes even more time than being on the air. Building at least some of my own stuff is still really important to me - call me old school.
My photography and assemblage art is posted on Flickr:
I ride my bike 100 miles a week - to and from work - in attempt to lose all the weight I put on sitting in the DX Chair (yes - DX-ing can be bad for your health!). This is my totally "hacked" road bike that has been turned into an AWESOME commuter bike. I can't even think about driving to work anymore - (cars are coffins):
I graduated from University of Pennsylvania, Lock Haven, moved to California and became Oracle's 127th employee - Gupta Technologies (SQLBase and SQLWindows) employee #30 and PeopleSoft's 400-something employee. I currently work in San Ramon at GE's Software Center of Excellence as a Senior Big Data Architect in the Transportation sector - specializing in Locomotive Fault Tolerance, Oil and Gas Pipeline Fault Tolerance and Predictive Analytics analyzing sensor data in Apache Spark and using Scala, Python and C to process graph data in GraphX. GE is at the forefront of the "Internet of Things" and "The Industrial Internet", and the company was started by one of my all time heroes - Thomas Alva Edison - a one time telegrapher! I've been a Database Developer, DBA and Data Architect for 34 years. My LinkedIn profile is here:
