Shed Building Plans

I dont do a lot of amateur radio operating over the summer months with the exception of Field Day or the occasional Straight Key Sprint.  At some point in the early summer before Field Day I like to set up my portable station and do a shakedown operating session to make sure everything is working properly with my gear.

In past years I have set up at my fathers place up on the shores of Lake Erie or even simply out in my backyard.  This year I drug my station to the RoadQueens house and we threw up a wire antenna to a big tree in the yard. I set up the transceiver and telegraph key on her coffee table. 

That weekend a special event called the Museum Ships Weekend Event was going on and I hoped to log a contact with one or more stations participating.  I enjoy WW2 history and this event is full of it.  As a history buff and radio enthusiast I find it a very unique experience to communicate with other amateur operators aboard these old naval vessels sometimes even using the ships original radio equipment.  

My first contact was WW2IND.  Unfortunately the U.S.S. Indianapolis was sunk during the war so the club operating the event was set up near the ships memorial in the town the ship was named after.  It took a while to receive the QSL card in the mail that confirmed our radio contact but eventually it showed up as a pleasant surprise in my mail box.    

How the second contact came about was a real thrill.  After searching around the band a while listening for ship stations to call and not finding any I settled on a clear frequency to call CQ myself hoping to make contact with any ham station.  After my first call I was promptly answered by a loud and clear signal with the call sign WW2DEM.  Holy Cow! A World War Two destroyer had just answered my CQ call!

There is always something interesting going on at Recumbent Conspiracy Headquarters and this weekend it was the Straight Key Century Club Week End Sprint.  I took a few hours out of my busy weekend schedule and got on the air for some casual contesting.  Dividing my time up between three different sessions I made a few contacts starting on Saturday night; followed by a few more with my coffee Sunday morning, and later in the evening as the sprint wore down to the finishing time.

For July the theme of the sprint was "A Revolutionary Sprintathon"  Earlier this month America celebrated her Independence and to apply this to the sprint in an interesting way a bonus of 25 extra points could be won by establishing contact with stations in each of the original 13 colonies plus Britain and France.  I never made a connection across the pond but I ended up with 27 contacts in 19 different states eight of which were in one of the original thirteen.

*Original thirteen colonies.  Only one bonus of 25 points can be taken per colony.  Multiple contacts with other stations in the same colony do not count as additional bonuses.  Too bad to as I hit three different stations in Maryland.

As often happens my mind experiences Morse Code overload and I need a break but Im still in the mood to make contacts with my ham radio.  During the sprint I did check for signals on 20 meters (14 MHz) and the band seemed uncharacteristically dead for some reason. On my way back down to 7 MHz I stopped and had a listen on the digital/CW only band 30 meters.  The amateur service is considered a secondary user on this interesting little sliver of radio spectrum between the frequencies of 10.000 and 10.150 MHz.  What this means is we can use the band for amateur activities as long as we do not interfere with the bands primary users which are probably made up of governmental, military or scientific services.

30 meters is a cool place to operate which shares propagation attributes of both the 40 meter and 20 meter bands which lie both above and below.  Because of our status as secondary users 30 meters is off limits for contesting so the band is a nice place to go for quiet low power experimentation and ragchews away from the traditional ham bands which can be a flurry of activity on busy contest weekends.

I could hear some radio teletype signals and see that their traces were quite strong on my band scope so I knew propagation was in good shape.  I set my transceiver to 10.140 MHz which is considered a PSK-31 "calling frequency" and sent out some CQs to see if anyone could hear me.  After sending out ten or fifteen calls I was just about to give up when a strong signal appeared in answer and I settled in for a nice conversation with an operator named Don in Peoria, Illinois.  

PSK-31 is a great mode for casual ragchewing and its a real bonus if you know your way around a keyboard.   The digital software in my laptop keys the transceiver into transmit and converts keystrokes of data into audible tones which are then sent out through space by my radio.  It really is amazing and what modern amateur radio is all about.  If you can type at all you can easily stay ahead of the buffer and watch your characters stream out in real time just as you can watch the incoming text appear on your monitor from the other operator. Instant messaging via high frequency radio waves.

On the screen of my laptop among other information provided by the digital program is what is called the "Receive Window"  In this area the incoming signals decoded by the software are displayed as text so the operator can see whats going on.  Outgoing text is also displayed in this window and unlike voice or CW (Morse Code) modes the software basically records both sides of the conversation.  This is an interesting and handy feature as it allows an operator to scroll back through a contact to find information or keep the conversation on track.  

People always ask what us hams talk about on our radios so here is a fine example.  I simply copied and pasted the whole QSO from the receive window and stuck it here on the blog.  I left it just as it was so a few little decode errors appear like typos in the text but over all the exchanges are pretty clear.

As usual radio-activity ebbs to its lowest over the summer months here at W8MDE.  Other interests like bike riding and maintenance on my yard keeps me outside while the weather is nice.  Ive not totally disregarded my station though and have a couple upgrades to discuss.

With autumn comes the shorter days and colder temperatures and thats when I like to start concentrating on radio operations.

Not long into my ham radio career I joined the SKCC or Straight Key Century Club. Through this outstanding club I ran into a  couple Morse Code radio-telegraphy enthusiasts who happen to run a machine shop called LnR Precision located in Randleman, North Carolina.  Back in 2010 LnR purchased the Par End Fedz line of wire antennas from Par Electronics and has been manufacturing them since.

"LNR will be far better equipped to manufacture and expand the EndFedz line of antennas" and "will have much larger manufacturing capabilities and thus amateurs will benefit from much faster order filling. I wish to thank the many thousands of amateurs who have bought EndFedz and whom I think of as friends." - Dale W4OP

A couple weeks ago I installed a brand new antenna from LnR called the EF-Quad.  This is a unique wire antenna that can operate on four bands; 10, 15, 20 and 40 meters with a 200 watt power limit.  My average power usage is about 50 watts or less for most of my operating so theres no danger of burning out the matchbox of the antenna where the coax feedline attaches.

Early in the spring I cut down the two Maple trees in the back of my yard because they had grown too big for the property.  Because severe storms seem to be becoming the norm I decided not to push my luck with the potential damage risk the big trees posed and had them removed.  I wasnt sure how I was going to like loosing my backyard shade but Ive adjusted and found the benefits far outweigh the negative.  I now enjoy a full view of the beautiful night sky and this fall I wont be spending hours raking up leaves. My neighbor was even happy with my decision because he noticed he was no longer constantly cleaning out small twigs, leaves and other detritus from his swimming pool.

The one problem I did have to overcome was loosing my antenna support.  In the meantime I simply pounded in an 8 metal T-post and tied off the antenna support cord to it.  This changed the orientation of the wire antenna into what we call a sloper in ham radio but showed little or no change to the performance of the antenna I had up at the time.

For a more permanent solution the RoadQueen helped me sink a 16 treated four by four in the corner of the lot to attached the support cord and raise the far end of the antenna up into the air a little bit higher than the T-post.    
 

The matchbox up on the tower is at a height of about 38 and the end insulator is now at 17 above ground.  Ham radio antennas work best when theyre up as high as possible and in the clear.


At the top of the post I screwed in a stainless steel eye bolt along with stainless carabiner and pulley to make it quick and easy to lower the antenna for tuning or other maintenance.  At about the four foot level I screwed in a cleat to make fast the support line.


The antenna was cut nearly perfect and was working fine right away.  I made some contacts on 15, 20  and 40 meters but have not yet found an opportunity with 10 meters open to try that band.

Local stateside stations within about 1,000 miles boom in loud and clear due to the relatively low height of the wire.  Working DX is not out of the question either and I had some good fun contacting a few foreign stations using the EF-Quad.

 

Heres a short blurb I wrote about the key for my QRZ.com bio page:

"This key is the latest addition to my key collection and is my first choice if I wish to send with a hand key.  The Pro-Pump was built by LnR Precision of North Carolina, USA.  Its design was inspired by and closely resembles the legendary Amplidan Professional Marine Key sadly no longer in production.

I enjoy straight key sending. I have tried many different keys and in my opinion the long lever design is superior when it comes to hand keys. Sure Ive only been pounding the brass for a short six years and was never formally trained as a radio officer but I appreciate quality tools and fine craftsmanship. I know it when I see it.  The precise and solid feel of the Pro-Pump allows me to send the cleanest code of all my keys. I use "arm off the table" European style of sending which I believe yields the most crisp and accurate code. Prior to acquiring this key I used the SKCC version  of the NT9K Pro-Pump.  That key was virtually the same but with highly polished brass and a decorative painted base. I prefer the more business like appearance of the Pro-Pump Standard model. A very handsome addition to my shack."

Last week I put the key on the air and had a blast participating in the 2-hour Straight Key Sprint held once a month by the SKCC.  These short weeknight sprints are great fun and the speeds are a comfortable 15 to 20 words per minute just right for hand key brass pounding.
