The Great LoTW Outage - Continues.

By: AA4LR

Update July 1, 2024. LoTW is back up! It is running slow, but it is available. Thank goodness.

--

When I wrote the article back in May, I hardly thought that LoTW would be down a month later.

Sadly, the outage continues.Β 

My suspicions were correct, however, that this was something more than a simple networking problem. The ARRL has since admitted their network was viciously and uniquely hacked. I can certainly understand their caution to make sure that every system linked to LoTW is given a clean bill of health before turning the system back on.

Earlier this week, on Tuesday there was apparently a brief period of time when LoTW was accessible. A couple of my ham buddies managed to upload some contacts. They'll have to wait for confirmations when the rest of us can get in.

I do hope it is soon. I'm really missing this service.

The Great LoTW Outage

May 16th, there was an issue with Logbook of The World (LoTW). I could not load the main page at all -- receiving an error indicating the server wasn't responding.

That's pretty normal stuff, actually. There are dozens of problems that can result in this kind of error, so I wasn't surprised. I figured the ARRL staff would address it quickly. But, after much of the day, I was still getting the error.Β 

So, I sent a message to lotw-help@arrl.org, informing them that the web site wasn't responding, kindly asking when they expected it to be back up. I mentioned I was surprised there was no notice of the outage on the ARRL.org web site.

Later that day, the ARRL put up a noticeΒ that there was a service disruption involving access to the network, and that it affected LoTW and the ARRL Learning Center. They even updated it the next day, addressing concerns users had over information privacy.

But then, nothing happened. Not until May 22nd, when they updated the notice without really adding any information.Β 

Now, part of this delay may be due to the fact that much of the ARRL staff were all out at the Xenia Hamvention. But, that was a week ago.

What gives? Sure, networking problems. Honestly, though, as a computer professional, networking problems generally don't take more than a week to solve. I'm beginning to suspect there's something more than the ARRL hasn't told us, but I can't be sure.

I'm really missing access to LoTW. In the last 20 years, it has really become central in my enjoyment of the hobby. I do hope I'm wrong, and that ARRL manages to fix this problem soon.

Fixing up the Cushcraft A50-3S

A50-3S standing tall and
straight next to the house.
Last year, I moved the A50-3S out of the yard and up next to the house. I used a 19 foot mast made of two pieces of EMT. While putting it up the reflector bumped against the roof and turned askew about 15 degrees.Β 

Never the less, it worked well. I worked a few Europeans and several South and Central American using this antenna.

Still, it needed a bit of work. A one-piece mast would be better, and I could straighten out the reflector when I swapped masts. A bead balun at the feed point wouldn't hurt either.Β 

So, I researched these. You would not believe what a 20 foot piece of 1 1/2" 0.058 wall aluminum tubing goes for these days. A few years ago, I purchased a 12 foot piece of 2" diameter 1/4" wall 6061-T6 tubing for my gin pole. It was about $150, which seems right for such a substantial piece of metal.Β 

But 20 feet of the thinner mast? They quoted me $500! If I went with the 1/4" wall, well that was manufactured with a different process -- extruded instead of rolled, so it would be $250. Ridiculous. There had to be another solution.Β 

I did have 20 feet of mast in two 10 foot pieces. This was from an earlier experiment. I had an old Butternut Β HF4B that I had rebuilt, and was hoping to erect in Fulton County. I bought two pieces of Rigid Metal Conduit (RMC) for this purpose.Β 

EMT and RMC are easily found at your local Home Depot. But it isn't exactly what you would call structural. EMT is design to bend. Easily. I have had some success using it as masting for very small, light antennas. The two pieces I used on the A50-3S lasted for over eight years, plus the several years holding up a 19 element 2m boomer Yagi. RMC is more substantial, and comes with threaded couplings to connect them together.Β 

Two pieces of 10 foot RMC was $30 a pop, so this wasn't a cheap experiment. Even with the coupling tightened all the way down, the 20 feet of mast had a substantial wobble in the top section. I tried inserting a solid piece of HDPE. That helped, but not enough to hold up the HF4B.Β 

It occurred to me that this might work with the A50-3S, even with the wobble. The A50-3S is held upright by a wall bracket at the eve of the house, well above the wobbly union. I just needed the vertical support, and not so much lateral rigidity. Besides, I already had $60 invested.

First order of business was to find the doggone things. I put them away three parsonage moves ago, and had hidden them well. They were hiding in my basement. After that, I had to locate the piece of HDPE, which I found in another box.Β 

It all came together this week. My youngest daughter Lauren helped me to lower the existing A50-3S and mast to the ground. Off came the antenna and the feed line, and the old mast was disassembled and put away. Then I coupled the RMC together with the HDPE stiffener and taped the coupling joints against any water intrusion. With the A50-3S mounted on the new mast, the reflector was aligned with the rest of the elements.Β 

For a balun, I used five snap-on ferrite beads. I measured these at about 100 ohms resistive at 50 MHz. Five conveniently fit on the 9913 coax from the driven element to the mast, so that is what I used.Β

Swinging the new mast up into place without bashing the antenna against the house took some patience. The RMC mast is much heavier than the two pieces of EMT. Once vertical, I positioned the mast in the eve bracket and loosely connected the u-bolt clamp. Both my daughter and I lifted the assembly to the top of the railing. From there, I tightened the bracket to eliminate play, but loose enough to allow the antenna to rotate. I used a couple of extra 1/4" nuts as jam nuts so the bracket could not tighten or loosen.Β 

The antenna is easily Armstrong rotated from the base. Eventually, I'll mount a rotator on the top of the railing and retire my arms.

A quick SWR check showed a 1.2:1 SWR at 50.313 MHz. The antenna is pretty broad. Minimum SWR is around 50.8 MHz at 1.07:1. I suppose I could mess with the matching network to get a better match on the FT8 frequency, but the whole bottom 2 MHz of 6m is less than 1.5:1.Β 

The antenna is 28 feet (8.5m) off the ground with clear shots from the North clockwise to the South West. Points to the West and North West have to pass through the house roof.

I hope Es season hasn't passed me over yet.Β 

Halfway through the DXCC Challenge

Twenty years ago, when I first started uploading my logs to Logbook of the World, I began to pursue the DXCC Challenge award. I created lists of confirmations that I had, and began to try to fill in the band / countries I was missing. This has continued for years.Β 

In April of 2016, I gathered sufficient confirmations to earn the DXCC Challenge award. Since then, I've continued to pursue new band / countries practically every time I am on the air.

This month, I passed another milestone. Currently, there are 340 entities on the DXCC list. And the DXCC Challenge counts on ten bands, from 160m through 6m. That makes 3400 total items for DXCC Challenge.Β 

I recently collected confirmations over 1700 items on the DXCC Challenge. That's the half-way point. It's only going to get harder after this.

Fifty Years Ago - The AM Count-down

Original log book from
1971.
When I first got into radio, in 1971, I barely knew what I was doing. I had done some shortwave DXing with my GR-81, but that rig worked much better on the AM broadcast band than anywhere else. Just before labor day of 1971, I put up my first outdoor antenna.Β 

Previously, I had just used a spool of magnet wire strung around the ceiling of my attic bedroom. This was not a very good antenna. Just before school started in 1971, I bought a 25 foot roll of small speaker wire and unzipped it all. Soldering the two pieces together, this gave me 50 feet of antenna wire, which I strung out the window, across the garage and into a tree at the edge of the yard.Β 

I was eager to try this new antenna, so I proceeded to tune across the AM broadcast band that evening, and log each station I could. I started about 9 PM, and kept tuning until midnight. The next evening, I continued the process.Β

That first night, I had started at the bottom of the band at worked my way upwards. The second evening, I continued upwards, but then reversed and went lower in frequency. This made more sense to me, and my later "countdowns" that I would make in subsequent years all started at the top of the broadcast band and continued toward the bottom.Β 

Sep 4 log page.
This event inspired me that for the next several years, I would try to do a "countdown" around Labor Day weekend. It marked the end of the summer, but also the beginning of the radio season.Β 

I remember it distinctly. I would sit patiently and wait for the AM stations to ID, generally at the top or bottom of the hour. If I got lucky, they would ID sooner.Β 

Hard to believe that event was over fifty years ago.Β
