K1RA on JT65-HF

I’ve got the Elecraft K3 running JT65-HF in the house this winter finally using outdoor antennas I’ve resurrected in the backyard. I’m only running ~5-10w and the antennas are ZS6BKW @ 45′ NE/SW, a 40/80m dipole @ 40′ NW/SE and a several hundred foot long wire @40′ running west. Below is a quick view of the stations hearing my signal over the last 24 hours on the HF bands. Meter bands are color coded. Hover over a marker to read more about the station copying my signal. Click on the View Larger Map link below the map see a full page interactive map.

KW4VA WSPR Beacon

With the solar flux rising again in the winter of 2014 I’ve resurrected my PIC controller based WSPR beacon and put it back on the air on 28 MHz running 20mw to an attic dipole antenna. I’d developed a script awhile back to pull data from WSPRnet and display who has been copying my 20 milliwatt signal. Below you will see a Google map on which I plot stations who have received my signal over the last week. The red 0 icon is my beacon location at the intersections of all the lines. The other blue icon #’s are placed over the 6 digit grid square or approximate latitude and longitude of the receiving station. Those blue # icons represent what band (in meters) my signal was received. Click on the icons to read more information about the receiving stations to include their call sign, grid, distance, beam heading, average signal to noise ratio, # of reports posted, frequency and first and last times I was spotted. The color of the lines represent received signal-to-noise ratios (SNR) in dB [red <-20, -20 < yellow <-10, green >-10] and line thickness represents the number of beacon transmissions copied [thin<5, med< 10, thick>10]. Click on the View Larger Map links below this map to see a larger and more interactive map with more data for the past week, day, 12 hours and 1 hour.

Here’s what the APRS 144 MHz real-time propagation map looked like for that time frame. You can see that many portions of the U.S. were experiencing wide area ESkip over 600 miles.

Another useful VHF propagation tool to watch on a daily basis for these types of openings is the DXMaps VHF MUF Map of North America, which offers a real-time view of the maximum usable frequency (MUF) across the country.

K1RA as KW4VA /M in VaQP 2012

VaQP is over! You can read about my weekend experience by clicking the following K1RA as KW4VA /M in Virginia QSO Party 2012. In the article you can read and learn more about my operation as well as see pictures and videos from the weekend event.

I activated KW4VA from the mobile this past Mar 17-18 for the 2012 Virginia QSO Party. I ran 10 bands: 160-6m (SSB/CW) and 2m, 1.25m, and 70cm (FM). As the contest was broken into two segments 10A-10P Sat. and 8A-8P Sun., I’ve decided to run 2 separate routes.

Day 1 on Sat. I was to run west of Warrenton and down Skyline Dr. That consisted of 10 stops covering 12 counties: FAU, LDN, CLA, FRE, WAR, RAP, PAG, MAD, RHM, GRN, ALB and AUG. I didn’t quite make all the counties I planned.

Day 2 on Sun. I was to run an eastern route towards D.C. and south down I-95. That was to consist of 17 stops covering 17 counties and cities: FAU, PRW, LDN, MAX, MPX, FFX, FXX, FCX. ARL, ALX, STA, FBX, KGE, CLN, SPO, ORG and CUL. Again I didn’t quite cover all the ground.

You can see my planned route on the map below. It not exactly what I managed to cover. Read to follow on article mentioned above to find out the actual details.
