ham radio Projects and musings from a (Relatively) new operator

Ill-Advised Antenna

8/28/2019

0 Comments

 
     In one of my recent posts (the one about my attic antenna) I mentioned my tendency to feel obligated to give things a try, especially if someone has advised me otherwise.  I don't know if its just stubbornness, or if its the desire to see it for myself, but it does seem to be how I roll.  Well, I've gone and done it again - this time with a portable antenna.
     If you know me at all, or if you've read other posts of mine, you're probably aware of my affinity for portable operations.  My love of portable ops has introduced me to a great group of individuals, some of whom I volunteer with to help support Parks on the Air.  The group of "tech admin" that work together to support the website, database, etc. for POTA meet virtually once a week to go over whatever things we need to, in order to support the effort.  Because we're all hams, we often end up just "rag-chewing" a bit after we cover the "business" end of the call.  During one of these chats, I happened to mention that I was disassembling a washer that had just gone bad so I could recycle the metal, and in the process, I ended up with this bit from a transformer:
Picture
   I joked with the team that I should unwind it and make antennas, seeing as there must be hundreds, if not thousands, of feet of this tiny enameled wire wrapped around it.  One of the guys - Thom, W8TAM, suggested that it probably wouldn't work out that well, being so small and a solid wire.  He's probably right - I can't imagine how many times this skinny, solid, wire could be flexed, kinked, etc. before breaking, but the trap was set.  He inadvertently set me on a mission of "well now I have to find out....."   So, now I have this:
Picture
     It's nothing fancy - just a random-wire end-fed with a counterpoise.  The counterpoise I lay on the ground, and I think I cut it around 33ish feet or so.  The antenna element (the one marked with the red tape) is cut at around 70 feet.  Inside the box is a little 9:1 unun that I build a while back (I wrote about it here.)  With my portable setup, I can tune this on pretty much any of the bands between 10 and 80 meters.  
     Now that it's built, the interesting bit will be to see how many times it can survive being deployed and repacked - so far I'm up to 3.  But hey, even it only lasts for half a dozen deployments, I've got a whole pile of it that I can just keep unwinding more from as it breaks :-)

On Frugality and Another Hole

8/15/2019

0 Comments

 
     I recently acquired another piece of gear for my ham shack, which prompted 2 things:
  • Making another hole in my "equipment wall"
  • Sharing some advice for those who are in this hobby, and are frugally minded, either by choice, or forced circumstance.
  So what is the piece of equipment that inspired these two things?   Here it is:
Picture

    I am certainly not an audio "buff" and I only have a very basic knowledge of audio equipment, but I had a couple things in my shack that I wanted to accomplish that I thought would be aided by adding a mixer.  Primarily, I wanted an easy way to have the option for a couple different microphones at the same time so that I can accommodate guest operators (mainly my kiddos) and be able to route these to multiple radios.  I also figured this would be a nice way to interface the same microphones and headsets with a couple different computers and phones for work conference calls and webinars that I do from my home office.  I've only just grazed the surface of getting everything set up, but so far I'm liking it much better than my old "patch panel" and swapping plugs in and out for the different tasks.

The Advice

   Acquiring this mixer lends itself to sharing something on frugality, that I hope can be a help to younger hams getting into the hobby that might be new in their careers, without a lot of money left over for ham radio purchases, or even to older hams on a fixed income etc.  
   I love ham radio, but like many of you, I'm not swimming in piles of money to be able to spend on it.  I have a good job, and make an ok salary, but a large percentage of what I earn is getting socked into college savings for my kids so they don't have to start their working lives in debt the way I did.  Because of this choice, I am very fugal with my hobby.  With that thought, here is my advice for enjoying ham radio on a budget, and for frugality in general:  
Be patient.
   This might seem like an oversimplification, but it is actually a very powerful practice.  When there is something you want (like a new piece of ham gear, or a robot that mows your yard) put yourself on notice for at least month before making a purchase.  In my experience this does 3 key things:
  1. Waiting forces you to really think about the purchase, and prevents you from rushing in and ending up with buyers remorse (i.e., did I really just spend $1300 on a lawn robot, and then also spend money to join a gym, when I could just be getting some of my exercise pushing an actual lawn mower that can be had for practically nothing?)
  2. It allows you to consider "do I actually need this thing, or is there a less expensive alternative that will satisfy what I'm after" (i.e. do I really need the fancy $4000 SDR, or would I be perfectly happy with the rig I can now get for a small fraction of that, just because its "old technology.")
  3. Taking the time to do this consideration lets you casually research options and do some poking around.  If you've managed to stockpile some good karma, I've found that the universe will often present you with a very viable alternative.
  My new mixer is a great example of this.  I decided several months ago that I wanted to purchase a mixer for my shack.  Since I have limited "hobby" budget, I was dragging my feet, waiting to save up some cash, because mixers with the features I was after were all a decent chunk of change, even if looking for used ones on ebay:
  • Sweepable mids, so that I could adjust the frequency of the mid range to add punch where we like it for ham radio
  • Multiple sets of outputs, for outputting the audio mix to multiple locations/devices
  • USB interface, to get audio into and out of the PC for radio use, without needing to rely on the "analog" sound card inputs and outputs that can be problematic at times
    While dragging my feet and doing my research, I stumbled across the mixer that I ended up buying.  Basically, because I waited, I ended up coming across a sale on these mixers because the company that makes them has discontinued them.  I presume that this is due to the move to digital audio, and less demand for analog mixers.  Because I was being realistic with myself (i.e., I just want to have casual chats on ssb - I'm not a professional broadcaster) I was very comfortable buying something that is "discontinued" considering the fact that it only cost me $150, for something that was previously sold for $400 and up.  Also, being "new" to audio equipment, learning with something relatively inexpensive made way more sense then shelling out hundreds of dollars.
    So there you have it - I've got a new mixer that was pretty much as inexpensive as one can be had with the included features, and hopefully you've been encouraged to "be patient" when considering those big purchases - you just might end up finding something that does what you need, at a fraction of what you thought you were going to need spend!
     Lastly, if you want another example of "Be Patient" Go back to Part 1 of my new shack build and check out the date that I started this whole adventure...it certainly didn't get put together overnight!
   P.S.  I'll be sure to share more about my thoughts on the actual mixer once I've used it for a while, but if you think the price sounds right, I found it at Full Compass.  I can't give any official endorsement, and I get nothing from them if you buy one, but I figured I'd at least share where I managed to snag what seems to be a decent deal.

Attic Antenna - Don't Knock it Till You've Tried It

7/18/2019

1 Comment

 
     An unfortunate disease, that I don't think is unique to ham radio, is "knowitallitis."  This all-to-common disease is the direct result of spending more time reading about a topic than actually practicing it.  The symptoms are quite obvious when you know what to look for - the most common is making comments on Facebook and QRZ, in a rude or indignant manner, about how "(insert subject) will (never/always) do what you (expect/don't expect) and I know it because I read the information at (insert random hyperlink here.)
     One of the subjects in ham radio that commonly falls into this category is attic antennas.  Quite often we see questions or hear comments on these antennas, and it seems like the ham radio internet trolls show up in droves to offer their commentary, many of which I suspect are not speaking from personal experience, but rather from the aforementioned disease of "knowitallitis."  Whenever I have seen these debates I have just quietly lurked in the background and watched the fray.  Moving forward however, this will no longer be the case, because I can now speak from personal experience!
     So, what were my reasons for putting up an attic antenna?
1) Mostly, I wanted to see, first hand, what the hype/anti-hype was all about
2) I had some wire scraps that I could solder together to make longer runs, but didn't want to rely on pieced together wire to hold up outdoors
3) I thought it would probably be quick to throw it up there, vs. getting stuff tossed into trees (I was way off on this!) while I continue building out my shack and antenna farm
   What I ended up putting in the attic was a fan dipole for 40 / 20 / 15 / 10, with a 1:1 balun at the feedpoint.  The ends of the 40 had to wrap around the perimeter of the attic a bit to fit, so the 40 meter element is almost like a folded dipole of sorts.  Regardless, there are numerous articles in the ham-sphere about building a fan dipole, so I won't go into that - I really just want to share some bullet points with my thoughts on an attic antenna, now that I can speak from first hand experience:
  • SAFETY FIRST!
    • Make sure you do your RF safety evaluation
      • With an attic antenna, depending on your ceiling height and attic height, it might only be a few feet from the antenna to the heads of people roaming around under it.  hamradioschool.com has a pretty slick RF Safety Calculation sheet available here.  For SSB, you'll probably find that you're okay anywhere on HF with a standard 100 watt radio, but if you run high power, or run high duty-cycle modes on 10 meters, you might start running into some of the exposure limits. 
    • Dangle your ends
      • Remember that in a dipole these are high voltage points, so you want to keep them clear of pretty much anything else - since I attached my attic antenna to the overhead rafters, I let the ends dangle down a few inches so they are "hanging free" in the middle of the attic space, away from any of the wood, insulation, other wiring, etc.
    • Wear PPE!
      • This may seem odd ("It's just my attic") but the company I work for has had several employees injured and one killed, this year alone, as a result of falls and accidents while doing work in attics and on top of joists.  We consider minimum safety gear in these environments to be hard hat, gloves, safety glasses, and if there is no walkway built, a safety harness.
  • As far as antenna's go, it isn't terrible.   I can make contacts, so if getting "something" put up that allows you to talk on HF is your primary goal, this will do it.
  • Installing it was terrible - attics are hot, and tuning a fan dipole is finicky.  Bad combo in the summer time.  My roof also has a pretty low pitch, which means the attic is tall enough that you want to stand up, but too short to actually do it.  This means you end up doing the squat walk, and constantly bumping your head on the underside of the roof (this is where the hard hat will save you!  no one wants a roofing nail in the head!) After even a few minutes of that, I was shot - your mileage may vary depending on the layout of your attic, and your physical condition.  For me, I didn't mind doing it, but in another 5 or 10 years, I probably won't want to be screwing around up there:-)
  • The attic antenna does pick up more noise than my outside random-wire antenna, but only when the AC unit (which is in the attic too) is running.  Other than the AC unit, there isn't much in my attic, so when the AC isn't running, I can't tell a difference in noise between the attic antenna, and my outside random wire. If you have a bunch of wiring and equipment in your attic, you'll probably pick up a lot of noise, if your attic is fairly empty, like mine, you'll probably do just fine.
  • I also don't notice a discernible difference in receive signal strength for like 98% of the signals I hear.  It's only the faintest signals that I might be able to hear better on one than the other.
  • I have set off my fire alarm once when transmitting on 20 meters, - the idea that you can cause issues in other equipment due to proximity of the antenna is definitely a real thing :-)  The smoke sensor that activated was on the ceiling below one of the antenna ends - about 2 feet away.
     So, with all that, here's the real question - would I do it again now that I have first-hand experience?

Nope.

Its not that the antenna is bad, its just that it isn't great, and getting it installed in the attic was a genuine pain.  Considering I have no antenna restrictions and plenty of trees in my yard, the effort to get this thing put in the attic was completely ridiculous.  If you have restrictions that force you into the attic, go for it, but if you can put your antenna anywhere else, try that first - but than again, if you're like me, you've already completely disregarded this entire post, and decided to try it just to learn it first hand...

     If you follow me on Twitter or Instagram, this might be considered old news, but I wanted to officially share so that anyone who is not on social media, that stumbles across my blog, can come up to speed:-)

A couple weeks back I shared that I finally made a decision on a rig for the shack, and I cut the hole in the wall where it would poke through (the wall of my operating position is about 4 feet from the back wall of the actual room, so that I can access the back of the equipment easily.)
Picture

     In the last several weeks, I finally got to a couple things to "finish off" this little piece of the project.  Namely, I made a face frame, sized perfectly for the rig, to go around the opening where the radio sticks through, and I also added a couple other useful tidbits:
The first was one of these little items, so that I could have a full-time voltage display, along with some quick power-access for phone and tablet charging, right at the operating position.
The second thing I added while I was making some dust was one of these decorator pass-through plates, so that things like my paddles, the keypad for the rig, etc. could have their cables run to the back of the rig, while keeping a cleaner look than just a hole, or jamming them under the body of the rig.

    I'm pretty pleased with how it turned out!

​As you look at the pictures, if you're wondering why the rig slightly off-center, that is actually for 2 very purposeful reasons: 
  1. Most importantly - I wanted the big knob on the radio to land where my arm and hand naturally landed as I sat at the desk, so that I wouldn't have to be doing some kind of weird reach-around past my keyboard to get to the radio controls :-P
  2. At some point in the not to distant future I plan on adding a VHF/UHF rig, and some other accessories that will "balance" the feel of it.
As a final note, for those who wonder where the "mess" is kept (some twitter folks pointed out that every ham is obliged to have a messy workbench) it is actually on the small workbench space that is just behind me and to my right, as I sit at the operating position.

POTA Plaques 2019

6/24/2019

0 Comments

 
Good day all!  Just a quick note to share with any of my readers who happened to miss the announcements that we have started sharing about the Summer 2019 Support Your Parks Event:
​
   For this second annual event, I am coordinating the sponsorship, and distribution of a series of plaques for Parks on the Air, Inc. that will be up for grabs during the Support Your Parks, Summer 2019 event.  This event takes place on July 20th and 21st UTC.
     These are no ordinary QSO party plagues!  Up for grabs will be premium series plaques, on black piano-finish wood.  The Award is laser engraved on an 8x10 textured black aluminum plate with a silver Florentine border.  Check out these beauties, which were awarded during this event in 2018:

Picture

​For 2019, we have a list of plaques that may be available, depending on the number of individuals or clubs that volunteer as Sponsors – if you or your club is interested in sponsoring a plaque, read the “plaque sponsorship information” section later in this document.  The final list of plaques that will be up for grabs will be shared via the POTA Facebook Group and POTA Slack Channel 1 week prior to the event.
 
I will be once again sponsoring the “Most Contacts, Activator” award, to get the ball rolling.  

General Rules and Items for Consideration
  •  Plaque winners outside of the continental US will be responsible for any cost over $15 associated with shipping plaques.  Winners will have an opportunity to decline the physical plaque if desired.
 
  • The POTA database will be used for data collection for the awards.  All activator logs must be submitted within 3 weeks of the end of the event, winners will be announced before the end of the following month.  Hunters do not submit logs.
 
Plaque Sponsorship Information
  • Previous sponsors have first priority in sponsoring the same plaque as they did the year before
 
  • Because of the high quality of these plaques, sponsorship of a plaque costs $115.  The price of the plaque varies depending on the number of characters in the winner’s name and information, but is generally between $90 and $100.  Flat rate shipping to send the award to the winner is $15.  After all plaques are paid and shipped, any remaining funds from sponsorship collection will be donated to Parks on the Air, Inc.  If final cost of plaques and shipping is greater than the amount collected from sponsorship, I will contribute the balance.  If the winner of your sponsored plaque declines receipt of the physical plaque, you as the sponsor will have the choice to either have the plague made and sent to you, or to have the full amount of your sponsorship donated to Parks on the Air, Inc.  All Plaque sponsors will be provided with a copy of the final invoice for record keeping and any valid tax purposes.
 
  • If you or your club is interested in sponsoring a plaque, contact me at  N3VEM@parksontheair.com and you will be provided with a list of plaques available to sponsor.  If you decide to sponsor a plaque, full payment must be made by July 12th, so that we can announce the final list of plaques that will be available.
