May 25th, 2013. Unplugged...

WPX CW 2013

This past weekend was extremely beautiful here in Alaska! The weather was outstanding for a holiday weekend here in the US. We saw temps in the 60's and 70's, which caused extreme melting of the snow and ice resulting in lots of flooding. Rivers are still running crazy as the snow melt continues. We were in the upper 70's yesterday so if ever there was a doubt that summer has arrived, well no more! 

This was a morning view of our QTH on Saturday morning, May 25th, 2013. I had hoped to make a few hundred contacts in the CQ World Wide WPX Contest but the solar conditions decided otherwise. Another weekend of turning on the radio and hearing none, or very few stations. I managed a handful before I officially pulled the plug Saturday morning.

Split Ends

With the bad band conditions, it was not hard to unplug from the rest of the world. It was time to begin the dismantling of our station. Fourteen QSO's was not my goal for the weekend but it was what it was. My first HF QSO when moving here was with Ed, K8QWY on November 28th, 2003. I had a 2 meter SSB QSO, which was officially my very first QSO, with long time friend Sean, KL1SF on November 27th, 2003. And here it was, May 25th, 2013 and 52,937 + QSO's later, my Mosley once again finds itself being packed up, awaiting another installation at another location. Closer inspection of the beam found it still in wonderful shape. Penetrox continued to keep the elements looking new. I only found a small amount of moisture in one location, and oddly enough, it was in one half of the boom. Penetrox had the water beading like wax but still, there was no sign of oxidation. Good stuff for sure. The beam and tower have taken an arctic beating here and have withstood all that was thrown at it. I'm sold on Mosley for that very reason. 

Laying Down the Tower

Once the beam was off the tower, I removed the mast and rotor from the Hazer and then lowered the Hazer to just above the crank. It was time to lower the Rohn 25 for disassembly. The tower made it safely horizontal (thanks to Polaris) and the scene around the house took on a more non-ham profile. It felt extremely...well, ham naked! Once the Hazer was off the tower, we worked at removing the top section. That was the toughest section of all and understandably so. The top section was where the Hazer and beam were mostly parked and it took the worst beating when the weather turned bad especially if I had not lowered the antenna to a weather safe height. Once the top section was removed, the remaining sections nearly pulled apart with ease.

Once Section Left (Non Multiplier)

I'm letting the sun warm the ground around the last section of our second tower before digging it up. The smaller tower was the home to my 6 meter beam and 2m/440 vertical for several years. I had dropped the 6 meter beam and had intentions of putting my Hex Beam up on that tower, but it never made it from assembly to elevation. It is now disassembled with my other antenna's and looking forward to being used at our next location. My vertical (Hustler 5BTV) was unburied from the snow bank and it too was disassembled and packed up ready to operate another day. All the antenna's and tower are now in one organized pile awaiting the day the moving van arrives.

As camping season is upon us, I'm looking forward to operating KL8DX/P, as I've done in previous years. The camper is nearly ready and my portable equipment is once again out of mothballs and ready for use. But for now, the Mosley has once again entered into hibernation at 1930z, on the 25th of May, and getting a well deserved break. I have many of what I call, "Mosley Memories" to keep me smiling for many months to come. 

Wallpaper to Wind Gusts

2011 CQ World Wide RTTY DX Contest Certificate

Nothing gets me more excited for the up and coming contest season like some wallpaper reminding me of what a great season last year was! I received this certificate in the mail this week and it will be proudly displayed on my wall with my others. Winter is fast approaching here and temps are below freezing over night these days. It won't be long before snow starts to accumulate in the yard and the days become extremely short. Thankfully, contest season warms the heart and the shack! It will be time again to get out some "butt glue" and stick to the chair in front of my HF rig for hours on end. I'm hoping this contest season is even better than last!

Reflector missing part of an element

Alaska recently experienced some early season Chinook weather systems and the wind storms did a bit of damage in Anchorage and left hundreds without power for days. Here in the interior, we had our share of wind and rain. I happen to be working on a window project during the last blow and heard a loud crash from the back of the house after a 63mph wind gust. I looked out the window in time to see part of my beam go crashing to the ground. I immediately went outdoors and I found a portion of my reflector element missing from my Mosley beam! It appeared the screw that was used to secure the elements together worked loose and the element fell to the ground as my antenna bounced around from the wind.

Only damage from hitting our metal roof

I inspected the section of my antenna closely and I could only see this dent in the trap from where it struck our metal roof. Everything else appeared okay and a search for the missing screw was in vain. I was just leaving for a short vacation so I tossed the element in the garage to repair it upon my return home.

After enjoying a week in Seward with friends, I returned home to an ever growing "to do" list. I managed to clean my wood stove chimney this evening and since I was on the roof, I decided to go ahead and get the beam back in working order. 

Penetrox working as it should

I was once again excited to see that the Penetrox I had used was working just as it should. There was no sign of oxidation on the element and it looked like the day I put the beam up. I can't speak highly enough of this great stuff! I've used it for years on the recommendation of an elmer of mine and I will always have it handy for any and all antenna projects. It has proven itself to me for many years now and has helped extend the operating life of my antennas. Good stuff and I'll leave it at that.

HF beam nested

My HF beam is nested for a few more days. I need to replace my guys to my Hazer and then I need to replace my broken house bracket. I just need a few more dry days to get that done and I can once again put my antenna up to the 43' level and start chasing DX.  And yes, if you have been following my blog, you will see that my Hazer has yet to find a place on my small tower. I need to make a run to "town" and get a 1¾" mast pipe. Once I have that, I can get that thing in the air as well. I'm looking forward to having a beam on 17 & 12 meters!  When it comes to tempting fate with Mother Nature, she tends to always win. At least that seems to be my luck anyhow.

Penetrox & Smoked

If you have been following my blog, I have mentioned that I began experiencing some problems with high SWR after a RTTY contest last year. I looked at some supporting documentation available from Mosley that helped me narrow down the issue to 15 meters. Each trap consists of two coils, with the inner trap catching 10 meters (band is still flat across the board), the second coil traps 15 (SWR off the scale) and 20 as it turns out, is a summation of the element (about 4.0 to 1 SWR in the SSB portion). Keeping that in mind, I knew I had to drop my beam and start pulling traps off of my elements to see which was producing my problem. Alaska has been seeing some pretty warm weather here due to a SE wind pattern so I took advantage to drop my driven element off of the boom to dive into the traps. I accomplished this yesterday and today I pulled the element apart.

If you have never used Penetrox, I would highly suggest it. One of my long time friends and one of the hams that helped me get my start into this hobby  suggested Penetrox. I have been using it ever since. When placed on connecting parts, it helps prevent oxidation without effecting the electrical characteristics of your antenna. I have had my beam up for several years now and when I pulled a piece of the driven element out of the trap, I found it to be in the same shape as it had been when I put it together a few years ago (see photo above). I will not build an antenna without this stuff!

 

I proceeded to pull the traps off of the driven element and I found that the Penetrox did an outstanding job there as well. In the photo above, I just wiped off the excess (bottom trap in the photo) and it shines like the day I assembled this beam.  Now, keep in mind, I used this beam for several years when I lived in Ohio. It operated there, made the trip to Alaska, and has taken a beating with extreme weather we experience here. I'm happy to say, with continued preventative maintenance, this beam will probably outlast me.

As I tore into the one of the traps on the driven element, I could detect an odor that pretty much confirmed my suspicions. I also had a bit of difficulty getting the trap apart on one end. As I was finally able to muscle the inner workings of the trap from the housing, I found the following damage showing

what happened during the RTTY contest I had been operating. I happened to make my best score yet in a RTTY contest but success came at a cost.

 When I pulled both traps apart, I found only one had this extensive damage. I wonder what my chances are of having the problem in only one trap? I won't be able to tell until I either inspect each trap individually or repair this one and put it back on checking the SWR curve with my beam to see. The other issue is, the insulator is riveted onto the tube (as seen in the photo above). So, it seems I will be touching base with Mosely looking for parts. If I wanted to get replacement traps from Mosely, they quoted me a price of $478.60 for this beam. Thankfully, replacement coils only run $39.50 each!  Living on a tight winter budget, you can sure guess which parts I will be ordering!

I would purchase another Mosley antenna in a heartbeat! It has done well but even the best antenna's have their breaking points. This beam has survived extreme cold, high wind gusts over 70 mph, ice, and more. In the end, it was RTTY at high power that did it in. You need to know the limits of your equipment. From the Mosley website, the following graphic below describes the limitations of the Mosley TA-34-XL antenna which I should have paid a bit more attention to prior to banging out a RTTY contest on legal limit high power all weekend long. I am proud to say, the beam did not fail until many hours of high power RTTY operating (actually, the last few hours). I can't see myself owning any other manufactured antenna during my ham career.

 

So, I can only hope that I can repair this trap and get it back in operation before the extreme cold and snow arrives. If not, I can always print this photo and keep it close as a grim reminder of what happens when you ask more from your equipment than it can take. My Ameritron AL-1500 might be enjoying the rest but I'm sure not enjoying the lack of activity. If I don't get this beam fixed, I may have to take up a new hobby for the winter as my 5BTV just ain't the same even though it's a good antenna.
