OK, regardless of what many “old hat” hams think, there is a lot of kit building and homebrew activity going on in our little “geek” subculture.  I don’t bother with the discussions with many of my friends, as they don’t go anywhere to see the truly neat projects people are developing.

To that end, many hams have asked me over the past few months about scopes (even a recent topic on “the zed”).  Basically, you can go one of four routes.

1: Buy a super expensive scope

2: Buy a decent used scope for a couple hundred

3: Buy a USB/computer based scope

4: Buy a brand you may not be familiar with, hack it, and get double what you paid for (in the $400. range).

I’m a fan of 2 and 4.  Both have their merits.  A used O’scope (not really Irish either) is a bargain, you can get a name brand and will cover most of what you need in our hobby.  Used scopes are also great to learn on as well until you figure out what you really may need.

That leads us to a “no name” brand.  The Rigol is truly a neat scope.  I used one on my last job for about 9 or so months and it really had some neat features.  It is portable, can store images to a USB drive, can connect via USB to a computer, the list goes on, but here’s a few:

Not a bad scope for the $400. range on ebay.

But…… (think Vince from “Slap Chop”)…… if you act now, because we can’t do this all day………

Dave Jones over at the EEVBlog has a neat video on Youtube on how you can double some of the specs…. for nothing.  Be wary of some google searches on the topic, some want you to hack into the scope and do all sorts of nonsense.  This is a simple first start and many people have had great results with it.

If you would like to go to the actual Rigol page and look up the specs and download the manual, go here:

Finally, if you’re still not sure what you are looking for, you may be able to try a scope at a few places.  Some trade schools, community colleges and such will let you come down and just take a look (or attend a workshop).  There is also a growing number of “hackerspaces” around the globe.  A “hackerspace” is a place to explore and learn technology in all it’s facets.  Some vendors (Tektronix for example) have some really good resources on their websites as well.

Nice weather and an open schedule allowed for some radio time this weekend. The QRP ARCI Fall QSO Party made some buzz so I loaded up the gear and headed out by the lake.  I put up an 88ft doublet in an inverted vee. I shoot a line over a tree limb at about 40ft and use that for the center and have two 17ft Crappie Poles that I use for end supports. That allows me to reorient the antenna to suit the conditions.

Ground Mount Closeup

One of the things I threw together is a simple mount for the crappie poles. I use a 2ft piece of PVC with a couple bolts inserted at right angles to one another at the base to keep the pole from going all the way through to the ground. The PVC is attached to a 3ft piece of aluminum angle iron that with 3 stainless steel hose clamps.

Crappie Pole End Supports

The poles are pretty limber and take a bit of a bend but do a good job of handling the 24 gauge teflon wire I use.  As you can see in the pictures, the mounts do the job and don’t cost as much as commercial counterparts.

So it was a good day and I made a few contacts, enjoyed the outdoors and had a nice picnic lunch with my XYL down by the lake between QSO’s.  The bands were pretty decent and I gave points to 20 of the more serious contestants out there.

p.s. The Polar Bears will be out and on the air next weekend. Give a listen, hear?

Wow! Great way to bring together a lot of ham radio ops on a Saturday using all sorts of technology!  Way to go! QRPSPOTS.COM is normally used by QRP ops to spot each other when we are out operating portable or to alert others of band openings. It was ALIVE with reports and updates from all over the USA and even a few DX ops adding input too! In addition, several QRP reflectors were buzzing with updates and info. What a great community effort this turned out! Congrats to all and thanks to QRP ARCI for helping get the word out.

Iowa High Altitude Balloon Project

One of the 4 States QRP bunch, Terry WA0ITP, provided the 20m beacon again and has some great info on his informative website.

But for me, the coolest thing was listening in on the streaming webcast of  VE3EN and his wonderful IC-7700. Sure wish I had thought of recording a bit or doing a screenshot to share here. But what a treat to listen in and hear the beacon’s signal right up until touchdown. Thanks Kevin for a fun way to eavesdrop on this event since the lawn mowing crew took over my condo’s yard and didn’t allow me to put an antenna out today. There is a ton of info and creative website construction on Kevin’s website and it is worth spending some time looking at the solar cycle data.

Congrats to the team for a successful event today and for bringing so many hams together for a good learning experience and something out of the ordinary. Well done W0OTM, well done indeed!

Here’s my dilemma:

I am a rookie homebrewer. My kit experience is good, but I have struggled to build direct from schematics. Part of it is my lack of ability to conceptualize the physical layout and part of my challenge is lack of building experience and mentoring.

What should I use?

Several of my antenna tuner projects seem to have a TON of hand capacitance effect. They are built in plastic cases, some from the Shack and some from the local surplus shops and hamfests. Most commercial tuners are built in metal cases and I wonder if that would eliminate the sensitivity to the tuning hand?

I have a couple metal enclosures I can use and a great ham friend sent me some thin copper with adhesive tape on the back.  I am thinking of slapping some copper tape inside the plastic cases and see how it works.

So, I am putting it to the vote:

Note: There is a poll embedded within this post, please visit the site to participate in this post’s poll.

And for the record, the vote in the poll  for best ham radio QTH in the US was won by West Virgina. Here is the top 5:

• West Virginia (17%, 11 Votes)
• Kansas (14%, 9 Votes)
• Texas (8%, 5 Votes)
• Hawaii (6%, 4 Votes)
• New Hampshire (5%, 3 Votes)

Thanks and 72,

The QRP-L reflector has been buzzin’ with the news and chatter (positive and some negative btw) about a new project to design and build a new transceiver for QRP HF use. YAHOO!

K8IQY Style Test Setup

What I love the most about this is that the QRP community is able to contribute ideas, resources and participate much like the Open Source software community operates. This could really be a fun project for our Central Florida QRP group. After all, we are not that far from Diz W8DIZ who is facilitating and coordinating this project.

If you like to build, experiment and try some QRP operation with a new rig… you should tune in and join the fun.

This is the last week to vote in the poll on my blog for the best US QTH for ham radio… Here’s the standings as of Sunday at 2100 EDT:

• West Virginia (17%, 10 Votes)
• Kansas (16%, 9 Votes)
• Hawaii (7%, 4 Votes)
• Texas (7%, 4 Votes)
• New Hampshire (5%, 3 Votes)

POLL RESULTS SO FAR:  West Virginia is in the lead for best Ham Radio QTH in the USA… One more week of voting… Have you voted yet? Here’s the link to vote!

Last weekend I played in the QRP Afield event and had fun with fellow Polar Bear QRP Club members on the air. It was a great time. Once again, the antenna tweak won out and under the influence of a great blog post by Polar Bear #20 VA3SIE, Martin in Ontario about the 88ft Doublet, I caved in and put one together the night before the event. Oops, I did it again! But this time I had excellent results and the antenna worked as advertised.  LESSON: Sometimes it pays to follow your heart and not your head.

Civil Defense Logo

I also remembered how I learned a lot as a young teen aged ham via the Civil Defense program. Remember that time?

Watching a weather report about tornadoes reminded me of a great learning experience. The Palm Sunday Tornadoes of 1965 hit the counties north and east of my home in Elwood, IN. At only 15 yrs old, I was the assistant emergency coordinator and ran the 6 meter emergency communications net on Sundays.  Our county and city Civil Defense teams had setup equipment and were ready for disasters and those tornadoes reeked havoc on our area.

Path of the Palm Sunday Tornadoes

Our teams rolled out the emergency vans, and the adults helped this young ham handle traffic for the state police and other government emergency responders.  The old yellow CD Gonset Goonie Bird rig is still something I remember fondly. I loved running that thing!

LESSON: Give the young hams some responsibility and empower them. They will be there when the time comes and will never forget how older folks treated them as peers and gave them an opportunity to do something important. I bet that kind of opportunity will still attract young people to our great hobby. We need them! They need us!

The Yellow Goonie Bird

Ever see one of those tie bars or pins that say, “IYKDWYBDYKGWYBG”  My dad had one back in the days when men wore ties. The thing used to bug me cause he didn’t tell us what it meant right away. We tried guessing for a few days before he got tired of 7 kids all ganging up on him.

It is the famous “If You Keep Doing What You’ve Been Doing, You’ll Keep Getting What You’ve Been Getting!” Not sure who gets the credit for that one, but it sure stuck with me all these years. Of course, I’ve heard my bosses recite it a few times along the way too.

It only hurts when I laugh, or think, or move, or…use a new antenna in a contest!

That’s what this series of posts is about. Not repeating mistakes I’ve made. Maybe you can learn from my mistakes and save a bit of time. Or maybe you’ll just get a laugh and some relief from knowing someone else made the same mistake you’ve made. HA!

Well, last night, I did not follow my own advice. I put together a new antenna a few hours before the NAQCC Sprint and set it up. LESSON: As previously mentioned, don’t try to use a brand new antenna in a contest.

Ooops I did it again. Strike TWO! It was a disappointing night and too late to try to get another antenna up before the 2 hour sprint was over. So no contacts for me, I’m still scratching  my head. Was it the antenna, me, or the band conditions? BUT… I don’t think I’ll pull that one again. Unless I have a hole in my head…
