Early Winter Reading: Becoming a Ham (Part 10)

Becoming a Ham – Part 10
By T. A. Benham (SK – formerly W3DD, a callsign which has been reassigned.)
Tom Benham, now a silent key but who most recently held callsign W3DD, was a ham radio pioneer, and being blind didn’t even slow him down! Join us now as W3DD recalls more about satellites in the early days.
The Trailer
During April of ’59, the students and I heard of an offer from the Government. If we went to Indian Gap, near Harrisburg, we might be able to pick up some surplus equipment. Two boys and I went and we found a fully equipped trailer that was designed for tracking aircraft. It had a parabolic six-foot dish on top that was driven by a sophisticated system from inside. The trailer was 20 feet long and about 8 feet wide. We could have it for the price of getting it hauled to Haverford, which turned out to be $200. The college comptroller authorized the expense and the trailer was parked in a little lot behind the Physics building. With the help of several students, chief among them Amateur Ridgley Bolgiano, the trailer was converted into a satellite tracking station. The 6-foot dish was too small, so we set about finding a larger one. I had heard that ITT, in Nutley NJ, might be interested in giving a hand, so three of us went to visit. We were received most cordially and I asked my contact if they had any parabolic dishes that were due to be scrapped. He paused a minute, looked out the window, picked up the phone and called the Disposal Department. “Hey Jim, you know that 12-foot dish outside my window? Well, it looks like hell, cluttering up the lawn. Please send it to Haverford College, attention T. A. Benham and get rid of the unsightly thing.” That was more than we could have hoped for, but it wasn’t all. He next called his wife. “Dear, I have three very interesting fellows in my office and I want to bring them home to dinner so you can meet them.” We went to his house, had a very nice lobster dinner and a pleasant visit. In a week or so, an ITT truck appeared with the dish. The boys and I got it put together and mounted on top of the trailer. Then Ken from Gerald Electronics came out and helped get the equipment inside the trailer in good operating condition. Since it was intended to track planes, it was nowhere near ready for satellites. When the trailer was ready to be installed in a location suitable for tracking, it was moved to the middle of a large field about a quarter-mile behind the Physics building. We drove two stakes into the ground and strung a string between them to provide an exact north-south line so the tractor driver could point the trailer as nearly north as could be arranged. He had to maneuver the trailer several times to get it lined up to our satisfaction. We had built a heavy platform for it to rest on so it wouldn’t settle in the ground and perhaps alter its position. It was very interesting and exciting. We had electric, telephone and teletype lines buried from the nearest pole, which was about 300 feet away. One of the interested boys paid the monthly charges for the phone, another paid for the teletype, I paid the electric.
Linkup with NASA
Now we became a significant link in the NASA tracking chain, at least until they got their multimillion dollar system going. Ridgley built a remote control system so we could turn on functions in the trailer from anywhere. For example, I was coming home from Washington one evening and knew we had to track something about midnight. We stopped in Baltimore and by telephone I turned on the heat, and the receivers to give them time to stabilize. At that time it was illegal to use phone lines for private purposes, but we dodged the rules. One afternoon, there was a knock on my office door and a man entered saying, “I’m from the FCC. I have a complaint from the telephone company that you are running equipment by remote control through their lines.” “No, we’re not connected to their lines and are not violating the regulations,” I replied. “Well then, why have they complained?” I explained that we had mounted a coil on the wall under the wall phone in the trailer. When the phone rang, a voltage was induced in the coil which we used to control relays, timers, etc. He wanted to see, so I took him to the trailer and showed him. He was amazed and left saying “I guess we can’t stop you from that!” “No,” I agreed. “We do all this without removing the phone from the hook, so there is no way the phone company could know we’re doing it. If they allowed us to use the line, they could charge and it would be much easier for us to accomplish the task.” I never found out who complained to Ma Bell. Now days it would be no problem. Back in 1936 when I operated my transmitter from the College I had a dedicated line for which I paid, but it allowed control from only one location. The conditions under which this remote system were built had an interesting quirk. Ridgley was driving back to College from his home in Baltimore. Somewhere along the rather poorly lit route 926, he dozed a little and ran full tilt into the rear of a parked truck. Both of his knees were smashed. He spent many weeks in Bryn Mawr Hospital while they were mending. It was during this time that he and I designed the system, on the phone and in person. Then we got tools and parts together and took them to him. He mounted and wired all of the components on a piece of Plexiglas® measuring about two feet square. It was a beautiful piece of work and functioned like a charm. I was heart broken when it was destroyed in a fire! The operating code was simple. Call the number and let it ring once, then hang up. Within a minute, call and let it ring twice. This set two timers running. Then call again and let it ring three times to turn on the heat, or four times to turn on a receiver, etc. Timing was important. To turn things off, let the bell ring four times the second call instead of three and this would set things up for being turned off. 
To be continued…

As I mentioned in my previous post, I’d been having a problem with powerline noise recently. The noise started to improve after about 2 weeks, with it disappearing for periods but then returning, until gradually it stopped entirely around a week ago.

As I mentioned, I had reported the issue after about a week to the local power company and while it took a while (just under two weeks), I got a message yesterday from a technician who had been dispatched to check out the problem. He said that he was at my house at the time (I was at work) and wasn’t hearing any unusual noise but asked me to call him to discuss the problem. When I first listened to his message it sounded like he had just listened with his ears (not with any kind of equipment) and my first thought was that I’d have to go through and re-explain the situation to him. I didn’t have a chance to call him back until today, but when I spoke to him I discovered that he did understand the issue and worked in the department that deals with, among other things, RFI and TVI problems.

He asked me whether I’d had issues like this in the past (I haven’t) and I talked about how the noise seemed to start right after the power was restored to some nearby houses after the freak snowstorm in October. He said that what may have happened is that in situations like this, when they initially restore power they’ll do so in a temporary manner just to get people hooked up then come back later and and do a more permanent job. His thought was that the temporary fix was noisy, but as they went back to “clean up”, they may have found and corrected the issues. So while I don’t know exactly what caused the problem, the good news is that the problem is gone.

The other good news is that he gave me his contact information and told me that if the problem returns that I should call him directly, at which point he’d come right out (instead of me having to wait a couple of weeks) to investigate.

I had a little sked last Sunday morning with PA3GNZ. And although this sked didn’t work out I had my HT on receive at the 70cm coversity channel. Now at a certain time I received 2 radioamateurs, the conversation went on and seems that one of them did not hear about the coversity channel before. He, like many others, thought he was being repeated by the PI2HVN repeater. It was the case as you can verify it at the internet and the other amateur told him that. It seems they had a chat before because the one mentioned earlier wishes to know more about coversity. Now, the other amateur told him to go back to skype so he could explain. And gone they were.

So what do we need radio for? Or is this the end of amateurradio (as we know it)?

My latest antenna project turned out very well. I took it to the beach for an on the air test this afternoon. This magnetic loop antenna tunes from 40 meters through 15 meters. In my haste to get to the beach, I forgot my antenna analyzer. After setting up the Mag Loop, I turned on the radio, turned the volume up full blast, and tuned the antenna for the loudest noise. Bingo!!

I was on the air. It couldn’t have been simpler.

The antenna is made from 3/8 inch copper tubing, 1 1/2 inch PVC pipe and a few odds and ends from Radio Shack. The heart of the antenna is an air variable tuning capacitor, 11 to 300 Pfd. The large loop, (the main loop) is fed with a half Faraday feed loop. All the information for building this antenna is readily available on line and partially from the ARRL antenna hand book.

Good links for Magnetic Loop builders: http://aa5tb.com/index.html,

My next Mag Loop will be 5.5 feet in diameter and made from 5/8 inch copper tubing. More on this as it develops!! There was an unexpected bonus in the speed and ease of setting up an antenna for portable use. I was on the air in minutes after getting out of the truck.

Please feel free to contact me if you are interested in building one of this fantastic antennas. The antenna has a very high Q so it has a steep tuning notch.

If you use a Faraday loop to feed it, it will be very directional. You can also use a Gama match instead of the feed loop, to feed the antenna. How did it work? I made a very nice contact on 15 meter CW with a ham in Milwaukee this afternoon. Not bad for 5 watts, an small antenna for a contact from Florida. The QSO ended with air boat QRN! The air boat passed by close to shore and I was on the water’s edge about 100 feet away. Next time I’ll bring the Bose noise cancelling headphones!!

Mt. Herman is in the books as my first SOTA (Summits On The Air) activation.  I’ll get to all the particulars in just a minute.  First, I want to thank a few individuals who truly made a difference in helping me make this activation a success.

Steve Galchutt, wG0AT.  If you’re the least bit interested in SOTA and/or any type of portable operations, you’re probably already familiar with his YouTube videos.  If not, please take a look.  Steve answered my many questions about the SOTA program and activating Mt. Herman.   Thanks Steve.

Budd Drummond, W3FF.  Budd is the Budd in Buddipole.  Without his fantastic products, all I’ll describe later would not be possible.  In addition, Budd helped spot me and cheered me on as the pileup started.  I was told he would probably show up and help stir up contacts for QRP stations.  Show up he did.  Thanks Budd.

As I described in my activation alert and the update released a few days later.  I’ve done backcountry hiking, backpacking, camping and have climbed a few 14’ers here in Colorado.  I’ve also operated portable HF before but have never combined the two in any way before today.  I had some (OK…a lot) of concerns and probably over prepared for this and also brought along a lot more gear than I truly needed.  More about this in a minute.

A major concern I had going into this activation centered around powering my station.  I have been researching the Buddipole nanophosphate A123 battery packs and decided to bite the bullet and purchase one.  Unfortunately, it didn’t arrive in time (no fault of Buddipole Company) and I had to go to “Plan B”.  This “Plan B” ended up being my old stand by which is a sealed lead acid 7.5 Ah battery weighing in around 6 lbs.  The battery is a couple of years old but I’ve maintained it the best I could.  I tested it prior to the trip by running the FT-817 on WSPR.  My station transmitted every 6 minutes or so for a transmit duration of almost 2 minutes each cycle.  It powered the 817 in this condition for nearly 3 hours before beginning to fall off.   

As a precaution I carried along a rollup solar panel which I’ve had a few years.  I was concerned  the battery wouldn’t hold out and figured if it was a sunny day, the solar panel would help supplement the battery.  The solar panel and solar charge controller weighs in about 2 lbs. 

My antenna setup for this activation was probably the one area I felt fairly confident with.  I’ve owned my Buddipole for several years and have used it in portable operations and even set it up at home a few times.  I’ve used it in the dipole configuration as well as vertical.  The Buddipole setup is a highly versatile system and of course very portable. 

For portability I went with the vertical versatee setup.  Which consists of a mast, the buddipole versatee adapter, coil, two mast sections and standard whip with one wire counterpoise.   The challenge I experienced was with the mast.  I had also ordered the new Buddipole shock cord mast and like the battery it didn’t arrive in time.  I wasn’t looking forward to carrying the extended mast I have for the buddipole tripod.  With the help of Steve, wG0AT he shared with me some pictures of using a hiking pole to support the vertical.   This will work….but did it really?

I think I finally fell asleep on Friday night just before midnight.  I was excited and I was mentally going through my pack (which I had packed a few hours before).  I finally convinced myself I had everything and fell asleep.  I was awake before my alarm sounded at 5 AM.  The plan was to have breakfast somewhere between Denver and Monument, Colorado and arrive at the trailhead by 8 AM local time (1500z).  This would allow me two hours to make it to the summit of Mt. Herman and setup to start calling CQ around 10 AM local (1700z).

I arrived at the Mt. Herman trailhead right on schedule and began the hike.  I’ll admit I’m not in shape…..far from it.  But I allowed enough time to do 1 mile hike (about 1000’ of elevation gain) and was on the summit with about 45 minutes to spare.  I started setting up the antenna first.  The wind was rough…really rough on the summit.  While I setup guy ropes, the wind was really punishing my antenna. 

As I previously stated, I was planning to lash the versatee to one of my hiking poles.  I brought along about a half dozen tie-wraps or zip ties.  I use these things all around the house and office.  I’ve always considered them the next best thing to duct-tape and bailing wire.  I’ve never had a tie-wrap break on me and figured this would be a better solution to bungee cords.  Unfortunately within 15 minutes the first two zip ties had been broken and the antenna crashed to the ground.  I had four more and decided to go for broke and use all four.  Success???

I had watched several of the Buddipole Youtube videos on setting up the versatee vertical.  The recommended setup was two antenna accessory arms, red coil: tap 5, standard 5.5 foot whip with all 6 extensions out.  The counterpoise 14.25 feet.  I managed to fight the wind, the vertical was standing straight and I quickly checked using my iP-30 antenna analyzer.  Just a few tweaks to the counterpoise and I had an SWR reading of 1.5.  This was good enough for me.

I quickly got my Yaesu FT-817ND setup and was in business.  I dialed up the HF Pack 17m frequency of 18.157.50, listened for a few minutes (heard nothing) then asked if the frequency was in use (heard nothing) asked again and after hearing nothing I began calling CQ.  At 17:15z the first station answering my CQ was just a few miles below me down in the town of Monument, Colorado.  wG0AT had been listening for me. Steve posted my callsign on the SOTAWatch website which alerted  all the other SOTA Chasers to my activation.  Let the fun begin.

The pileup was simply amazing and contacts flew into my paper logbook (just a Rite in the Rain journal).  From 17:15z through 17:49z I worked 28 stations consisting of 22 US, 2 Canada, 2 Germany, 1 Spain and 1 Czech Republic.  All on 5w.  I truly didn’t count on working DX and certainly didn’t count on adding to my DXCC count.  But the Czech Republic was a new DX entity for me and I’m truly pleased to have worked  him.  Thanks again to Steve, wG0AT who sent me the picture below showing my APRS route up to the summit and three of the DX stations QSL cards.

My plan was to spend about an hour working 17 meters and then try 12 meters.  However, just after wrapping up with W7RJC at 17:49z the vertical came crashing down to the ground.   The temperature on the summit was below freezing and I guess that made the plastic zip ties brittle and they just couldn’t handle what mother nature was dishing out.  I was out of options and decided to pack up. 

Besides the high wind, I could not have asked for a better day for my first SOTA activation.  The picture (below) was taken with my iPhone and shows the view from the summit towards the northeast.  Once I got everything packed away I took some time to enjoy a sandwich my wonderful wife made for me the night before and take in the beautiful sights around me. 

Just before strapping the pack on for the descent back to the car I took this photo (below) to capture just how pleased I was with the events of the day.  I had finally combined a couple of my favorite hobbies together into one activity and can honestly say, I can’t wait for the next SOTA activation.

This experience has helped me to also better understand I need to do more to get back in better physical shape.  As I’ve always said, amateur radio is different things to different people.  The best part about the SOTA program is it can be enjoyed both from a mountain top or from the comfort of your ham shack.  I’ve done both and will continue to chase and activate every chance I get.  I hope you’ll join me.

Until next time….

I saw this on Southgate this morning and figured I would simply repost the whole article as it’s got all the info and is to the point. If you work on 60 Meters at all, you may want to make sure you have this info handy. From Southgate ARC’s website here is the info:

By Bonnie Crystal, KQ6XA (used with permission) –

The U.S. Federal Communications Commission released a ‘Report and Order’ on November 18, 2011, with new 5 MHz rules for the Amateur Radio Service.

The effective date is 30 days after publication in the Federal Register.

Some of the FCC changes are to now allow Phone (Upper Sideband), RTTY, Data, and CW; with specific limitations on the use of these modes, as well as the maximum allowed power level is now 100 watts PEP (ERP) effective radiated power referenced to a dipole.

The FCC has deleted a channel and added a channel. The new 60 meter channel list (for General, Advanced, or Amateur Extra Class license only) is as follows (Suppressed Carrier):

VFO Dial frequency
——————
5330.5 kHz USB (center of channel = 5332.0)
5346.5 kHz USB (center of channel = 5348.0)
5357.0 kHz USB (center of channel = 5358.5) New!
5371.5 kHz USB (center of channel = 5373.0)
5403.5 kHz USB (center of channel = 5405.0)

PLEASE NOTE: The FCC deleted the channel 5366.5 USB (center=5368.0)
and “replaced it” with channel 5357.0 kHz USB (center=5358.5).

If you’re just getting started with CW, you need to know that learning Morse Code is only part of the puzzle. You’ll also need to learn basic CW Operating Procedures, and you’ll need to know some commonly used abbreviations, too. It wouldn’t be a bad idea to print out something like this and keep it near your key until sending and receiving these are second-nature:
