To me Field Day is about setting up a radio infrastructure where there is none.  Our Field Day setup is at a beach house on Holden Beach NC.
We had three antennas - a portable hex beam mounted to the hitch of my truck, an end fed random wire, and a CrankIR.  Our call was K4J.  We worked 4 SC station, N4AW, W4IT, N4EE, and K4NAB.  We worked Mexico, Croatia and PR.  One lesson learned was on the proximity of the antennas to each other because of the small lot causing RFI.  The only way out of our dilemma was to either work S&P or work multi single.  We did both.  We will likely need isolation filters for next time or take shifts.
We had very strong winds sometimes gusting to 40 to 50 mph.  The guys on the CrankIR took a beating and we had to monitor the tension.  The EFHW was on top of a shortened Spiderbeam pole at 30 feet on one end and at the 3rd story deck on the other.  The hexbeam survived the wind but only because the mast was lowered.  The ops were NY4G and WM4AA.
We had fun as always and had a good nights sleep despite despite a broken AC.

The Quest for #275

There is nothing magical about #275.  But you do get another sticker from the ARRL at this milestone.  After 275 it is a long slog.  The ARRL recognizes this and issues stickers after 300 every 5 DXCC entities.  Even 5 DXCC can take years to get at this stage.I consider myself fortunate to having line of sight to 275 after 5 years of DX Chasing

ATNO #271 Minami Torishima

Take, a Japanese ham operating under JG8NQJ/JD1 was QRV while away from his meteorological duties on Marcus Island.  He was spotted and I could hear him faintly at my SC station.  He was being worked by station after station.  I booted up my remote station in San Joaquin, CA and there he was loud perhaps S7 on the SteppIR Tribander.  I worked him at 100 watts.

E-mail from K9OT

  • Message 

  • Gm Ariel, good luck with the trip to FP. You will find that it is a very unique place. Take time to look around the island, and visit some of the shops. It looks like you are going to stay in St.Pierre. We have always gone to Miquelon and stayed at the motel, but I think that it is closed right now for renovation. There is a very good hardware store in St. Pierre if you need anything that you did not anticipate. I will try to make a QSO with you while you are there. 73 Paul K9OT FP/K9OT

This blog will be a mirror site to the website above.  It will be likely that updates appear here before they appear on the website.

I have secured a Microsoft Surface as the main DXpedition computer.  I have configured it to run N1MM and have tested its operation during the CQ WW WPX Contest during which it ran 7 hours straight on the internal batteries.

The WPX was also good practice.

Testing DXpedition Antennas


I got a chance to play with the vertical dipole array cut for 10m and turned out very well.  There is a resonance dip at 27300 kC as I cut the wires too long intentionally. I ran the math to move the dip to 28300 and will need to test it out again before I move on to the other bands.  Gifts from several hams W1TEF, NJ4F and K4JPG allowed me to purchase a 12m Spiderbeam pole.  That pole is a good performer. A picture of the VDA is shown below.  This antenna design has been used in several DXpeditions and even contest stations.  It was used in the "Microlite" DXpeditions to South Georgia Island VP8GEO and South Sandwich Island VP8THU near the Antartic.  It was also used in Ducie Island VP6DX.  It is also used in the contest station CN2AA in Morocco.  They are very effective seaside antennas.



Here I am with the pack of goods I have to carry.  I reduced payload by about 5 pounds from here.


Here is my tent arrangement below.  Yes, that is a solar panel resting on the tent rainfly.  It is Powerfilm and puts out a full 30 watts (its rating) under direct sun.  I was able to run the radio without the voltage dropping below 13V for about 6 hours.  



Here is the rig in the tent

Sleep - Contesting

It was first published by the Yankee Clipper Contest Club.  Thanks to Kevan Nason N4XL for posting it into the Swamp Fox Contest Group Reflector.

Thanks to Charlotte, KQ1F for digging up this article, and Fred, K1VR for editing it.
 At the February 1988 meeting, YCCC member, Thomas Scott Johnson, KA1QXI (now NW1I, who now lives in Concord, MA), a physician at Brigham & Women's Hospital specializing in sleep problems, spoke on sleep deprivation strategies - or how to sleep four hours out of 48. This is the first program we can remember where the majority of those present took notes! He began by telling us that most people come to the Hospital's Sleep Clinic complaining that they have trouble sleeping, and it is interesting to speak before a group that wants to learn how to avoid or minimize sleep. After a brief overview of the physiology of sleep (90 minute cycling, REM sleep, and so forth), he gave his recommended schedule. On Friday afternoon, have a reasonably good meal (but no alcohol) and take a three-hour nap, preferably from 4:30 to 7:30 PM EDT (for CQ WW Phone, which starts at 8 pm EDT), or 3:30 to 6:30, if the contest starts at 7 pm EST. When you get up, have some coffee. Eat no large meals during the contest, just snacks with high carbohydrates, low fat, and reasonable protein. Two hours before your normal waking time, take a 90-minute nap (this allows a full sleep cycle so that you will wake up refreshed), or sleep for 180 minutes. Then have another cup of coffee.

Only drink coffee when you awaken from your naps; otherwise you will have trouble falling asleep and will not awaken rested when you do sleep. The first afternoon of the contest, Saturday afternoon, schedule a 30-minute nap for sometime between 3 and 4 PM. Take another 90 or 180 minute nap the second morning. Optionally, take another nap the second afternoon, Sunday afternoon. [Ed. note: However, since you don't care what happens after the contest ends only a few hours later, you may load up on caffeine Sunday afternoon to avoid that Sunday afternoon nap.]

Avoid alcohol during the contest. Avoid heavy physical activity (such as tower or tree climbing) right before the contest since it promotes deep sleep. Keep the shack very brightly lit to keep you alert. When you do nap, do so in a darkened room.

Keep the shack warm, 72 to 74 degrees, since low body temperature encourages sleep.

First Simulation - Battery Draw Down Tests

Rig: KX3-KXPA100-PX3
PS: Gamma Research HP100
Powergate: KI0BK
Battery: Battery Tender Li-Fe-PO4 24 A-h
Computer: Toshiba Laptop
Software: N1MM Classic
Power Monitor: Watt's Up
Starting Voltage: 13.4 Volts (Fully charged)
Power Level: 50 watts on key-down (measured on a peak reading watt meter)

I wanted to realistically assess how many QSO's and how long I can run on my primary battery and how long I can keep logging and keying the rig with the laptop.  I had the laptop running in power save mode.  I turned off the Panadapter to reduce current draw on receive.  Current draw on receive with the Panadapter on is about 630 milliamps and with it off is about 480 milliamps.  My resting current draw is about that level.  Keying the rig brings the peak amperage to about 7 amps (6.5 amps with the PX3 off) but that is only momentary.  I ran for a steady 2 hours at about 175 Q's per hour.  At the end of the 2 hours I was down 4.4 amp hours according to the power monitor.  So, effectively, my average current draw was about 2.2 amps.  Voltage at the end of the second hour was about 12.9V.  At the end of the 3rd hour, the voltage had dropped down to 10.5V and the KXPA100 will not key up anymore.   At the end of the 3rd hour the laptop battery was almost depleted.  Realistically, 450 QSO's can be had in 3 hours of operating.  I generated that many mock QSO's in 3 hours of the simulation.  A second battery would double my run time.  However, unless I can extend the laptop run time through another laptop battery, logging will have to be done by paper and pen.  A solar panel can extend operating time if sun is available.  So between a solar panel, a second battery, a second laptop battery, 6 hours of operating time should be realizable with run time to spare.  That will be the subject of a second test.
