SOTA W6/NC-407 (and NPOTA RC 11)

richardsonHaving worked Mount Davidson, the highest point in San Francisco (283m), the only way to get more altitude (“excelsior!”) was to leave the city. I set my sights on Richardson East Benchmark (339m) in the Golden Gate National Recreation Area, just north across the Golden Gate bridge from the city.

After spending the morning in meetings, I again checked the weather forecast. Although it had been drizzling all morning, the lowest probability of precipitation occurred in the afternoon, so I packed my bags and took the 70 bus north from 5th and Mission. The timing worked out just right, by the time the bus got to the destination, rain had stopped.

IMG_20160122_132933The most convenient entrance to the park is at the park and ride station, “Spencer Avenue Bus Pad”.  Google Maps suggested taking one of the North bound buses, e.g, the 70 or the 4, northward past the stop and then coming back southward on another bus since the trail head is on the southbound side of the bus pad. This is not necessary, as you can walk from one side of the bus pad to the other through an underpass. This shaves off a lot of time and some extra bus fare.

There is a sign near the entrance, the morning sun trail. Stairs lead upward from that point, and the morning sun trail joins with other trails that circle the peak. The stairs wind back and forth a bit, but are not too steep. I did find the upper portion of the stairs slippery since it had rained earlier in the day and the stairs were covered with organic detritus (i.e., dead leaves).

At the top of the stairs, there is a scenic lookout, which includes a bench. The peak itself is visible from there, topped with commercial radio antennas. I ended up climbing most of the way up, but wanted to keep some distance to those antennas. Again, my antenna plan consisted of throwing the 10/20/40 end-feds into a tree.

I did remember this time to bring the VHF antenna and I tried putting out a call on the 2m calling frequency at the start and end of operation, but heard nothing. My business band was 20 meters, with 35 contacts. I was working two a minute for a while. I only had two contacts on 40m, which seemed alive with activity, but mostly QRO, so I might have been buried in the noise.

Some of the activity might be attributable to a comment that NF1R added on sota spotting network, that the peak was not only a SOTA peak, but also NPOTA RC11. I hadn’t realized that when I chose the location, but when I enter the contacts into LOTW, I’ll be sure to use the NPOTA unit number so chasers get NPOTA credit as well. The SOTA contacts have already been entered, but I’ll need to get home to update LOTW.

Best DX to the east was NY (preparing for a blizzard), FL and TX to the south, a good showing for Canadian stations (ON, QC, and BC), and westward, HI.

NAQP-CW from W2

IMG_20160109_203053I started in 2016 in Mauritius, but since getting a temporary license there requires a few months lead time, I wasn’t able to operate from there. I had about two days on the ground in Madagascar, and then packed again for the US for meetings in DC and San Francisco. This time, the FT817 came along and saw some use.

The night after I arrived, I rented a car and drove up to visit my parents in New Jersey. It was the weekend of the winter NAQP-CW contest, so when I got there I threw my end-fedz 10/20/40m into a tree, suspended the matchbox from another tree about 3 meters up, and ran the coax into the kitchen since it was chilly and drizzling out.

Weller: The Final Chapter

Well, I hope it is the final chapter. I’ve written before about fixing and then learning that I hadn’t quite fixed my Weller WESD51 digital soldering iron. After much manipulation, I think I ended up cooking the PIC chip on the PC board, so I just ordered another board. Long story short: replacing the old board with a new one worked and I now have a functional solder station. I have some details below about where I ordered the replacement board and how I installed it in case anyone runs into a similar situation (or, given that cyclone season is again upon us with massive voltage fluctuations on the mains, in case my unit gets toasted again and I need to follow my own instructions).

The other side of the wall

Space_Shuttle_Columbia_launching

I got back from a trip on Friday, woke up at a reasonably leisurely hour on Saturday and thought it would be fun to test the waters of the big CW contest going on. Almost immediately, I was drawn in and didn’t leave the chair for another seven hours. Since the CQ WW DX contest is based on zones and there just aren’t many contesters in my zone (39), it was very flattering to be the object of desire for the rest of the world, but being on this side of the DX wall is quite different from what I’m used to.

At the best of times, I was working three calls a minute in a jedi mind-trance, but that of course was not typical. There were plenty of times where I was dialing around, trying to get noticed with my 100W and two-element antenna. However, the converse was also a challenge – sometimes I would be plugging away at a good rate and then all hell would break loose. Somewhere, someone had spotted me and suddenly I would find myself lying on the space shuttle launch pad, looking up at the main engines sparking to life, while trying to hear a song playing on someone’s ipod on the flight deck. The experience of operating into a solid wall of callers added some new perspectives…

¡SSB en fuego!

This past weekend was the CQ WW SSB contest — one of the big ones. I usually have a vague idea about the approach of a contest and decide whether to take part on Friday of the contest weekend, but I had marked this one on the calendar ahead of time and was prepared. Aside from setting up everything and working a bit of SSB earlier in the week, I spent some time looking at propagation and figuring out where to point the antenna at different times of day to hit both areas with high densities of hams (NA, EU, Japan), but also beam heading that would cover the most DXCC entities, the multiplier for this contest.

VHF Update: Repeaters, Earth and Sky

Relais 5R8ZZ
Relais 5R8ZZ

I got an email from Albert, 5R8GV, last week alerting me and other hams in the area that Serge, 5R8GX/FR5GX, had put a repeater into operation: 5R8ZZ.  The repeater is based at his house and puts out 16 watts (after filters) through a quarter-wave ground plane antenna on his roof. The repeater’s input frequency is 145.150 Mhz and the output frequency is 145.750 Mhz (i.e., set your radio to 145.750, with 600 khz negative offset). No PL tones are used; instead send a brief 1750 Hz tone to open the repeater.

A quiet night at home

SurefireU2JPG
A tale of low power operation in the dark.

For the past couple weeks, we’ve been experiencing load-shedding that starts about an hour after sunset.  The capital region of Madagascar does not have enough electrical power production capacity at present to run everything at once, so there is a rotating blackout. Now that I’ve added some UPSes, this has minimal impact on my family because we have a back-up generator that comes online in under a minute — usually. Last week, the generator didn’t start rumbling and we sat in the dark [presumably] looking at each other.

OE1ZJW Field Operation

Operating position at the top of the hill. The hills are alive with the sound of CW.
Operating position at the top of the hill. The hills are alive with the sound of CW.

I was in Vienna on a business trip, but I had some time on Sunday to put the portable station on the air using my Austrian guest license, OE1ZJW.

At the Vienna radio club meeting, OE1VFW gave me two invaluable pieces of advice. The first was where to shop for electronics: Conrads. Their megastores in Vienna carry consumer electronics, hardware and tools, and hobby electronics like arduinos, raspberry pis, various kits, parts, project boxes, etc. I was able to restock a few items that I needed back in Madagascar. The other bit of wisdom: where to operate.

If I had lived in Vienna for a few years, I probably would have eventually come to the same conclusion: Cobenzl. It is elevated and far from any noise sources. I have rarely heard background so low. I could hear signals that would not even budget the S meter.

Just outside the city on the North side there is a wine-producing area known as Grinzing. From the Heiligenstadt Bahnhof, the 38A bus runs through this region and up to a park. Near the bus stop, there are restaurants and public bathrooms, so this is civilized sort of “field” trip. Behind these facilities, however, is a large public field.

A club meeting in Vienna

The QSL sorting area at club HQ.

For once I went to a radio club meeting in Vienna, but not in Virginia. Earlier this week, I landed in Austria, had some meetings at the Vienna International Center and then headed directly to the Landesverband Wien in Österreichischen Versuchssenderverband, i.e., the Vienna section of the Austrian IARU member organization. According to their website, meetings are held every Thursday at 17:00h. It turns out that this is true, but 17:00 is just the starting time — most come between about 17:00 and 19:00 (presumably the time is more exact on an evening with a scheduled activity).

The Ginger Polygraph

FeedDog
The frequently lit red light indicates that our dog is lying.

My dog Ginger has a problem: she really likes food. That, coupled with her uncanny ability to convince family members that she has not been fed adds up to an overweight dog. She is not particularly sensitive about the subject and besides, she doesn’t read this blog (does anyone?) so I don’t think she’ll mind if I write about our attempt to find a technologically sound solution to her overeating, which is really a matter of our overfeeding her.

Ginger is supposed to get two scoops of dog food, one in the morning, one in the evening. Mornings, however, are chaotic. I get up and shower, and my wife adds food to the bowl. Then, while my wife is in the shower, Ginger whines and I figure she hasn’t eaten, so bowl number two. Often we’re out the door before the kids have emerged from their rooms, and at least one of them will take pity on Ginger, who clearly has not been fed at that point, and she gets her third bowl. Pretty much any time someone walks past her bowl, it seems that she hasn’t been fed. You would think we’d be on to her now, but there are times where in our rush to get out, we have made the mistake of each assuming the other one fed the dog. Ginger reminds us constantly of these rare occasions.
