Broke the 100 confirmations mark today!

NPOTA, that is:


I actually have about 1/2 a dozen more that haven't been confirmed yet. According to LotW, those stations have not uploaded logs since their activations.  A few were a while ago, so I guess it's possible that maybe they won't.

While working a few today, it was extremely embarrassing and saddening to see so may out there have no clue on how to handle themselves in a pileup.  Guys ..... YOU HAVE TO LISTEN!

Throwing out your call sign ad nauseum without taking a moment to listen is the number one earmark of lid-dome. Seriously, if you send out your call ten times without taking a breath, how are you going to know if the activator is calling you back? By the time you've stopped sending your call, the activator has worked someone else and is calling QRZ again (and everyone else in the pileup has taken note of your call sign - you can count on it!). DON'T BE AN ALLIGATOR!  You know, all mouth and no ears! Throw out your call once - maybe twice max, and then open up those ear holes and listen!

Which leads to a second and related problem.  If you can't hear the station you are trying to work, you have NO business sending out your call, in the first place.  If you can't hear the station well enough to know that he's answering someone else - or worse, is in QSO with someone else; but you keep sending your call anyway ..... bad scene, man, bad scene.  You've marked yourself as a QRM generator and no one likes those. Don't rely on the Cluster. Just because DX Summit says Joe Ham is on 7.034 MHz at NPOTA NP256 ..... if you can't hear him, then don't even try.  It's a waste of your time and everyone else in the pileup is going to think you're an idiot.

Now everyone makes an honest mistake now and then, and that's OK,  But you can tell when someone has no clue as to what they're doing. And frighteningly, it seems to be becoming more and more common.

It's OK to be excited and enthusiastic. It's not OK to be reckless or use poor operating practises. Use common sense, read the DX Code of Conduct and you'll be OK.

The Best CW training app for Android

Morse Trainer for Ham Radio

I'm always on the lookout for useful tools to help increase my copy speed and enjoyment of CW/Morse Code.  Training applications for beginners that teach letters and letter groups are great to get started but after you're making QSOs and copying at useful speeds those apps get a little stale. 

I recently wrote about using the "Morse News" RSS reader application for PCs. What I liked about Morse News was that it would send the text of news articles as CW.  I found it useful as a natural language trainer but I didn't like being tied to my PC during training.  

I wanted a similar application for my smart phone.


Just the mobile ticket to CW training


I'm not sure how I missed the "Morse Trainer for Ham Radio" app up to now but I've been using it for a couple of weeks now and really find it useful.


Morse Trainer in QSO Text Mode


Training Modes

This app has all the standard Morse Code training tools such as letter training, letter groups, callsign training etc. It also can send the most common 500 words as well as a random sample QSO training mode.  That's all great but what I really find useful is the ability to send your own text that you type or paste into the app and even... wait for it... an ebook reader!  

I must really be a geek but I find the ebook reader makes this a must have CW training app for me.  I converted some of my ebooks into plain text (using Calibre) and placed them in the CWTrainer's application folder on my smart phone.  I then choose the ebook mode, choose a book and it will send it as CW to me and keep track of where I left off.  I use this ebook reader mode to break the monotony of my long drive time.  

ebook mode

It's great fun to witness the expression of the person beside you at a stoplight hearing Morse Code pouring out of your car.  Priceless.

I keep the speed higher than I can comfortably copy so I'm missing some of what is sent. There's nothing like reading an action novel where you're missing half of what's going on. Did Tex get shot or not? I missed that word, hehe.

While this app doesn't read RSS feeds like Morse News application for PC's the text and ebook reader modes more than make up for it. The only bug to-date that I've noticed on my phone is that if I rotate the phone while it's playing it will reset where it was reading from back to the beginning. 

Here's a video from the application's author describing it's functions...


And here's a link to the application in the Google Play store.

I have no affiliation with the maker of this application.  I just wanted to share.



That's all for now

So lower your power and raise your expectations

6m/70cm antenna updates at the QTH

I have made some changes to my antenna set up. A local amateur was selling a second 13-element 70cm yagi and a 6m HB9CV antenna at a low price so decided to acquire them.


The 70cm yagi was to replace the small 7-element one which I pressed into service as a hand held antenna for potentially finding my HAB payloads last year.

To be honest I wasn't really after a 6m antenna due to the size and visual impact. I have a 6m 'wooden' moxon I made back in 2014 but it is heavy, ugly and unstable so had been collecting cobwebs in the garage. I decided with the prospect of 'Sporadic E' season around the corner I would be foolish not to put it up.

The HB9CV wasn't in the best of conditions but seemed complete albeit it was purchased dismantled. The elements were a little weathered so I set about cleaning them up with a light rubbing down with some wire wool and a rag with a drop of WD40. On closer inspection the tube that made up the front element had some noticeable bending and on removing the plastic mounting to investigate I spotted a crack in the tube wall by the hole for the mounting bolt.

While it hadn't totally separated it would only be a matter of time before it did fail as it was flexing, the plastic mount was the only thing holding it together. I found a suitable piece of alloy tube from a scrap antenna which was a perfect fit inside the broken element. I cut a suitable length and pushed it up inside the element to the appropriate position and then simply drilled through and bolted either side of the central hole to stabilise and strengthen it (can be seen in image below)


The next issue I had to address was the feed point, it came with about six inches of RG58 coax projecting from it where it had simply been cut for removal by the previous owner. I prised off the cover cap to find it full of water, the reason being a hole in the back and it being stored outside I believe.


Thankfully the trimming capacitor seemed okay, while it was wet it wasn't corroded. It was all dried out and the hole plugged with silicon and I set about re-assembling the antenna which was a little fiddly to get the phasing line to sit properly but once done it was a simple matter of adjusting the capacitor to get the VSWR to a minimum in the SSB section of the 6m band. I mounted on the rotator pole just below the X50 collinear.


I used it last month in the 6m UKAC and while my operating not exactly earth shattering I was happy with its performance using just 10W in the low power section just "search and pouncing" for a little over an hour.
.

The 70cm Yagi was straight forward as was already assembled, I just had to make a slight tweak to the gamma-matching bar as the VSWR was unexpectedly high around 2:1 in the SSB segment of the band, it seemed to have been tuned for the FM portion of the band. I managed just an hour "search and pouncing" in Aprils 70cm UKAC, I started late and while signal reports both ways were a marked improvement I found the extra directionality and off beam rejection something I will have to get used not helped by a temperamental rotator.

It was an NPOTA weekend …..

in more ways than one.

I worked about 5 or 6 new entities between Friday night and Saturday, so I am getting really close to my personal goal of working 100.  The bands have been good the past couple of days, after totally stinking during the middle of the week, so that was a good thing.

I have lived relatively near Morristown National Historical Park my entire life. I think I've been there once before NPOTA.  Yesterday, I decided to take Marianne and our dog, Harold up there for the afternoon, as dogs are welcome there.  It was a beautiful Spring day, Marianne had an extremely rare Saturday off; and I wanted to do something with her.  It seemed like a good opportunity to enjoy the gorgeous weather, walk the dog and get some good exercise in for ourselves. It's because of NPOTA that I discovered that dogs are welcome there. If I didn't see that while I was up there, activating the park, I wouldn't have known otherwise.

Much to our surprise, when we got there, we found out that a Revolutionary War re-enactment was taking place:






The highlight of the day was when one of the re-enactors came up to me and tapped me on the shoulder. He pointed to the American flag that is embroidered on the left sleeve of my jacket and he said to me, "Kind sir, a question, please. It appears that you have a United States flag on your coat; and yet there are so many stars?  Certainly more than 13!"

I answered, "It's a long and sometimes bloody story, and I don't think we have time to go through it all, but I would like to thank you and your fellow soldiers for giving birth to the finest Nation on Earth."

He chuckled, and I chuckled at our impromptu time travelling scenario. In the end, it was great NPOTA day, even though this one didn't involve Amateur Radio.  So hats off to the ARRL for reminding me about some of the really cool places that there are to visit around my QTH.

In the evening, I decided that I would go out early Sunday morning to activate Sandy Hook, which is part of the Gateway National Recreational Area - RC08.





I used the Jackite pole and my homebrew mast holder and the PAR END FEDZ 40/20/10.  In a little over an hour, I made over 40 contacts on 40 and 20 Meters.  Bext DX was Alberta, Saskatchewan and California.  Not bad for 5 Watts, and if at all possible, the PAR will be my preferred antenna for future activations.  

I would have stayed longer, but I had somewhere to go with my daughter Cara, so I made due with the time I had.  It was a bit brisk while I was there, but it was sunny and clear.  If you click on the bottom photo, you just might be able to make out the New York City skyline in the distance, on the horizon.

Sandy Hook was my third activation, and I hope to do at least two more in New Jersey - the Pinelands and the Appalachain Trail in the Northwest part of the state.  When we go up to Lake George this Summer, I also hope to spend one day at Saratoga and activate HP42 while I'm in the neighborhood.
