K1RA on JT65-HF

On March 5, 2014, in QRP Low Power, by Andy K1RA

I’ve got the Elecraft K3 running JT65-HF in the house this winter using just attic antennas. I’m only running ~5w and the antennas are 40m = horizontal loop, 30m = dipole NW/SE, 20/15/10m wire beam NE/SW. All antennas are about 25′ off the ground. Below is a quick view of the last 25 station who have been hearing my signal on the HF bands. The number in the blue markers indicates the band in meters, the line color represents signal strength < -20 dB = red, -20 dB to -10 dB = yellow and > -10 dB = green. Click on the View Larger Map link below the map to interact with the markers and see the last 50 stations and even more details including callsigns, signal reports and distances for the stations that have received my signal.

K1RA @ K8GP Rover Jan VHF SS 2014

On January 27, 2014, in VHF Roving, by Andy K1RA

I’m celebrating 35 yrs since I made my first SSB/CW VHF contest QSOs back as a young WB1ALW and KA1GD back in CT.  This year I was fortunate enough to be able to rove with Terry W8ZN in this past ARRL January VHF SS contest. I assisted Terry in rebuilding the rover of Rich N3UW who graciously allowed us to take it out on a maiden voyage. I wrote an in depth article covering the preparation and contest weekend experience. I put together pictures, audio, video and some graphics and analysis maps covering our various grid stops. Check out the full article for more or click the picture below.

K1RA @ K8GP SVHFS Fall 2m Sprint 2013

On September 24, 2013, in Main, by Andy Zwirko

Check out my article covering the 4 hour sprint event I participated in recently. I had the pleasure of activating the K8GP contest station in grid FM19bb on 144 MHz during a spectacular tropospheric opening that occurred in conjunction with the radio competition. I captured some weather maps to explain the conditions that lead up to the nights great propagation. Below is a snapshot of the live 2m APRS tropo map that gives a slight idea of who was hearing who. Also visit my article to see some statistics on my best DX contacts, view my log and even listen to some of what I heard. Click here to read more!

K1RA 144 MHz ESkip

On July 25, 2012, in VHF Roving, by Andy K1RA

I was fortunate enough to catch a 2m ESkip opening on the evening commute home Tues. July 24 from about 630p to 8p local. Many locals in the Va/D.C./Md area were on from fixed locations working the opening. Locals K1HTV, K4RTS, W4CLJ, KE2N, N3ALN, N4MM, K3ZO and K4HJF among others, were all heard working the DX from 0 land and 5 land, much of I which I couldn’t hear. I was only using an Icom 706 MKIIG @ ~ 50w and a dual-band magmount vertical on the roof of the SUV, but I was able to work 4 stations in the mid-west. I logged N0IGZ (KS – EM27 @ 932 mi.), K0WYN (MO – EM48 @ 759 mi.), W0BLD (MO – EM37 @ 844 mi.) and K5SW (OK – EM25 @ 985 mi.). I copied 8 other unique calls during this time to include AF5CC (OK – EM04 @ 1174 mi.) who heard me but never completed, WA0CNS (MO – EM48 @ 645 mi.), K0DOK (MO – EM48 @ 714 mi.), KC0SNN (MO – EM27 @ 918 mi.), WB5AFY (TX – EM04 @ 1233 mi.), W7QJQ (OK – EM25 @ 959 mi.), KB5MR (OK – EM25 @ 1016 mi.) and N5UWY (OK – EM15 @ 1100 mi.). Click on any of the calls above to hear what I recorded from the mobile on my Android phone using an MP3 recorder acoustically coupled to the rig’s speaker.

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

On March 7, 2012, in HF Contesting, Main, by Andy K1RA

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.

CW QRP Foxhunts

On February 14, 2012, in Main, by Andy K1RA

I’ve been participating in this winter season’s 80m CW QRP Foxhunt as both a fox and a hound. The event occurs every Tues. night from 0200-0330 GMT between 3550-3570 kHz. Two stations (foxes) are designated to transmit and the rest (hounds) are poised to attempt and contact the two foxes within the 90 minute time window. More info can be found at the QRPFoxhunt web site or their QFOX Yahoo Group. I’ve been collecting fox contact logs for both the 80m and 40m events and plotting various statistics on Google maps. Check out my 80m analysis and my 40m analysis pages for some interesting graphics.
