W5N/SS-024: The Kindness of Others

Recently, my youngest son gave us an opportunity for an unexpected short vacation. We elected to head for Taos, New Mexico, our favorite 'local' destination.

Elizabeth and I decided that Saturday would be shopping for her and SOTA for me. Most of the peaks in the Taos area appeared to be 10-pointers. As I am accustomed to an altitude of about a thousand feet, I needed some advice.

I asked on the NASOTA reflector and got helpful responses from WA9STI, NU6T, KT5X and KD5KC. Fred and Scott recommended Sierra de Don Fernando, a 10-pointer that had an approach suitable for raw beginners and was a relatively short drive from Taos.

I began researching and packing up my K1-based QRP station. Here's most of what I took:

Yes, that's a big battery. This was a hurry-up vacation opportunity – and the quickly purchased Walmart back pack confirms me as a complete novice.

Friday, on the way to Taos, we had a chance to identify the turn-off from NM64 and took the opportunity to scout out forest road FR-437. Here is the key turn to FR-437 from 'County Road':

and this is the start:

Saturday, I made several mistakes while looking for the start of the summit trail off FR-437. I lost a lot of time until I spotted two mountain bikers and asked them about summit access. They were encouraging but did not know a path to the top. I then realized two things: the abandoned road I wanted (FR-445) was unmarked (as near as I can tell) and I had driven past the cattleguard marking the start. I turned around and found the unmarked road just as Fred describes in his notes on W5N/SS-024. Oh well.

Backpack on and hydrated, off I went.

I did well for the first mile or so. Then I could not pick out the landmarks Fred noted and was not finding a route to the summit. I was headed back to where I thought I had turned wrong when a hiker (and his dog, Ruth) caught up with me. I asked, and he kindly said “Follow me” and led me back to an area where he pointed to a vague set of ruts that led downhill to the north. He said, “You'll hit an abandoned road in just a few minutes. I remember the path to the summit to be marked and about a quarter-mile to the west.” Then he and Ruth continued on. Sadly, I never got his name.

I followed his instructions (and realized that the 'abandoned road' he mentioned was most likely the unmarked FR-445). After a quarter-mile of so, I found this:

The sticker on the fencepost says something like 'Road Closed – Do Not Enter', so of course I had to give it a try. In just a few yards, it was apparent that I was on the right path. After stops to catch my breath, I was on the edge of the mountain meadow mentioned by Fred. Here is the path leading out of the trees to the clearing (looking back the way I came):

And, in the opposite direction, here is the summit area. The high-point is near the center of the photo:

Here's a link to the best on-line map I could come up with that shows my approximate route. The turn off the abandoned FR-445 is marked “003”:

Sierra de Don Fernando Peak

I picked a couple of likely aspens that were near some shade and with a lucky rock I had one end of the 20M dipole up. The lucky rock then lost all its power and it took 6 tries to get the south end of the dipole to a nice height.

After just two “CQ SOTA”s, I got a call from K6EL at 1926 (2014-07-19) and I was off and running. Signals were strong and the noise I experience at home was completely absent. Wow.

I got past the fourth QSO and a minor pile-up appeared. I was really having fun when I heard a rumble.

I looked up from the rig and thunderstorms were surprisingly close. Thunder boomed again – and I decided that the top of a mountain with just a few trees is not exactly a safe place to be in an electrical storm. My last QSO was with ND0C at 1943. I packed up quickly and was off the summit in about 15 minutes. Here is were I set up the station:

Back in the auto and on the way down FR-437, I ran into the mountain biking couple and they asked how it went. I suppose it was pretty obvious from the grin on my face...

I had a great first experience at being an activator. I realize that some have done this many hundreds of times, but this was my first – and it will be one of my treasured Amateur Radio memories.

My thanks to the amateurs mentioned above, to the two mountain bikers, and to Ruth and the unnamed gentleman who saved the day.

The EZKeyer

AAØZZ EZKeyer II

After looking around for a external keyer to be used with my K1, I decided on the AA0ZZ EZKeyer from the Four State QRP Group.  

It was a very easy and quick build.  The instructions for both the build and operation are great.  Works fine with the K1.

For me, the features that caught my eye were the three memories (with more space than I anticipate using), the easy and quick speed change and the miserly battery consumption.  

I decided to package  my EZKeyer in an Altoids tin - like several of my other projects - and here's the result:

Adapting the Altoids tin was a lot more time consuming than using the very clever enclosure that is supplied with the kit.   Knowing what I know now, I would have built the supplied enclosure.



Also, as the battery life will approach the battery shelf life, I would have just soldered up a battery pack - and saved buying the 3xAAA holder.  No switch is supplied or needed except for a hard reset.

Recommended.

Wall-wart Repair

Wall-wart Repair

Yes, I know it's a waste of time and I could have bought a new one for the price of a couple of cups of coffee - but it was very satisfying.

We have one audio device at our house which has become a major part of how we enjoy television.  It's portable and depends on an occasional re-charge using a 5V wall-wart.

These things fail - and re-charging becomes a problem.  We have had failures in two modes:  as the result of a lightning strike and because the cable failed. 

It was pretty obvious that the lightning strike victim was toast as it was blown to bits.  The other failure took us a while to notice as the LED charge indicator is not readily visible in normal use.  We finally figured out that the charging was intermittent and a few simple experiments identified the culprit as the cable.

We ordered a new one and it occurred to me that if I could repair the broken one, we could have a spare.

I know that even if I value my time at half the minimum wage, I would be wasting money in trying the repair, but I like to fix things.  To quote my friend and co-worker Murel:

Use it up

wear it out

make it do -

or do without.

The first thing was to open it up (and make sure it wasn't toast).  The tools I used are in the first photo and the 'technique' (if you will allow me to characterize hitting something with a hammer as a 'technique') is in the second.  This was easier than expected:

Inside was what appeared to be a fairly nice regulator - and as you can see below, it was still working! 
 



 

I note here that I did not try to reuse the cable.  I have the advantage of being near a Goodwill Computer Store and cables with the appropriate connector are about 50 cents - in the USB to mini-DIN style.




Here I have re-connected the new cable.  What might appear to be a solder blob at the end of the cable is actually a bit of aluminum foil shielding that I finished removing after I noticed it in the photo:



 

Then I glued it back together.  You can see the unused USB cable end which I used when I mixed the epoxy.

Sure enough, about a week after I got the 'spare' working, we had another failure.  The spare will allow us to continue until we can visit someplace large enough to buy another replacement.

20-20 hindsight:  I should have bought a longer cable - and I should have bought more than one while I was there!
