Speculation-Biased Speculation…
May 9th, 2012 by kmack

If you are old enough, I bet you remember the game Fascination and that song in the commercial that stuck in your head all these years? For you new ones, here’s that commercial in YouTube format.

If you change the word fascination to Speculation, that naggy song becomes Speculation, Biased Speculation… the game we love to play! Seems like today’s political and journalistic culture has invaded ham radio if you follow the threads on QRP-L reflector about the Ten Tec 539 which is yet to be released. It has been diced, sliced and all sorts of factless speculation has already been thrown out as to why it won’t be popular or competitive with brand x’s new scrumpdillyicious xcvr. Whew!

I think it is a sad sign of the  times that instead of waiting for things to be released publically and from the source, products are already condemned as unworthy and judged based on hearsay and not true facts. It is bad enough that our culture does that in tv news broadcasts. Everyday we endure seeing the accused virtually tried and convicted on the screen by endless talk show hosts and experts often months before the courts are convened. I hate to see that culture spilling over from the current US political context where finger-pointing, wild speculation, and always attempting to  avoid responsibility and accountability begins to be spewed out on our hobby.

I for one will look forward to the final roll out of what looks like a very nice new transceiver from a US company before I make that buying decision.  Might be something I want, but who can tell until the process is finished and we get to see the final product? From here, it looks promising despite the speculation that is taking over all the airwaves and culture here in the USA. As for me and my house, we will wait for the facts!

QRP TTF 2012
Apr 29th, 2012 by kmack

Great weather here in Orlando for a good afternoon of QRP Portable. The QRP To The Field contest is always a good time to get out and give out a few more points to the serious contesters. I enjoy the concentrated QRP contacts and hearing my virtual friends once again. Every QRP event has a few regulars that are almost always heard. This year the bands were only so-so in Florida with lots of QSB on 20m which was by far the best for the day. It was solid at times and then signals would suddenly drop to the noise level which made RST reporting fun!

Just above sea level

Mt. Cedar Tree: Just above sea level

Because of band conditions, I spent most of the 4 hours on 2om, but I did check 15 and 10m on an hourly basis. To do that, I pulled out my Ten Tec Argonaut 509 and used a Buddistick with the base up about 12 ft.  I called CQ about 50 times on 15 m but heard almost nothing on 10m all day. On 15m I heard a couple Eu  (IV4 and DK)  stations but was not getting a response to my calls and only heard 1 or 2 US stations so I assume the band conditions here weren’t quite right for those two bands.

Managed 18 QSO’s in 4 hrs of switching between my Wilderness Sierra to an EFHW, Delta Loop for 20m, and the Buddistick / Argonaut combo for 15 and 10m.  40 m was full of Florida QSO Party stations and a couple of nearby (within 4 miles) stations were pounding my receiver and causing the AGC to go nuts when I tuned across them so I only managed a single contact on 40 before retreating back to 20m.

I’ll be looking to give out more points in upcoming contests. So call CQ and I’ll be out there lookin’ fer ya!

Breaking News…Grinches ALMOST Stole My Favorite SDR Site
Dec 22nd, 2011 by kmack

BREAKING NEWS!  Mack has rebooted and W4AX.com is back online. It is a huge blessing  and thanks again to Mack and the host of others who serve all of us! YAHOOO>>> Grinches lose! W4AX.COM is online again! Belay my last!

A few years ago, we did not know the term, Software Defined Radio but now it has become one of many new technologies that we hams are learning to adapt to our needs. As an antenna restricted condo dweller, I’ve found it most helpful for being able to listen to the bands at various times through the day.

Yesterday I learned my favorite site, W4AX.com is shut down due to abuse by non-hams and other constraints. A big thanks to Mack, W4AX and others who are the unsung heros that provide services like these and have allowed access to others over the years. The Reverse Beacon Network is another great service and we often forget the time and expense that our fellow hams have put into keeping them going.  As a blogger with multiple sites, I understand the challenges and resources it takes all too well.

I’ll miss being able to check the bands 24 x 7 on my favorite site, but perhaps it will prompt me and others to set up our own SDR site and share it with others. I salute those who like Mack paved the way for new technology to provide access to so many hams. Sorry that the burden got too heavy to keep it going, but know your work was appreciated by many. I’ll be sure to let others who are working behind the scenes know that they are appreciated too.

Blessings gang of pioneers and Happy Holidays to you all!

Contest Point Giving for Christmas
Dec 19th, 2011 by kmack

The weather was too nice to sit inside. In the low 70′s with a very slight breeze so after church and a short nap I headed out to try my hand at giving out points in the QRP ARCI Homebrew Sprint. My startup was delayed by curious folks in the lakeside park wondering what in the world I was doing and how I got that string and wire so high up in the nice tall pine trees!

Next to the Lake in the Sun

I checked 40m first with an inverted L end fed half wave and my trusty Stuner (KI6S Stu’s kit) and decided to change to 20m after not hearing much activity. 20m was decent and there were a few of the big gun qrp contest regulars shooting it out. N4BP, K4BAI, K0ZK and a few other were running stations while the little guys like me were mostly doing Search and Pounce. Hey it is fun even if you cannot run a frequency, right?

Sun went down about 1745 local and the mosquitos were quick to find the hole in my hat and attack. This time I remembered the repellant and after a few bites I took time to spray my hat and hair and the backs of my hands. The temperature dropped fast and my hands got a bit stiff pounding out the morse code on my J-47 straight key. 50 degrees is cold for a Florida evening. The darkness also brought out the raccoon family and it was fun to shine my flashlight on them and watch them stand on their hind legs and stare into the night wondering what the funny guy was doing in the dark.

Almost dark

Sun is almost outta sight

40m came to life after sunset and I finished with a respectable 20 contacts for about 3 hours of operation and was able to give some Christmas contacts to the needy fellow contesters who were chasing another certificate. What a great way to spend the afternoon… by the lake in the sun and outdoors playing radio.

QRPSPOTS.COM and IHAB Do it Again!
Oct 2nd, 2010 by kmack

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.

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!

Duh: Learning Curve #6 What’s a ham to do?
Oct 1st, 2010 by kmack

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.

Boxes

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:

Which material should I build with?

  • Metal case is the only way to go (79%, 11 Votes)
  • Use the copper tape inside plastic case (14%, 2 Votes)
  • Just use the plastic case (7%, 1 Votes)
  • Give up and buy a commercial tuner (0%, 0 Votes)

Total Voters: 14

Loading ... Loading ...

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,

New Open Source Rig Project? Dah Mini-Pig+
Sep 27th, 2010 by kmack

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!

Manhattan Style

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)

I am a CPG
Sep 13th, 2010 by kmack

Spent my birthday participating (casually) in the Straight Key Century Club Weekend Sprint. My Lake Fredrica neighborhood site was where I set up my shelter and 3 antennas. I had a 40m dipole fed with twinlead up 40 ft and running E-W. An End Fed Halfwave for 20m was nearly vertical suspended by a nearby tree. A twinlead 44 ft doublet on my 20 ft Jackite with the ends at 16 feet was setup running N-S to give me a bit of a mini-smorgasbord of antenna choices. Since it was really sunny, I hooked up my ACME GC100 Solar Charger and VW Solar Panel.

Bands were decent with 40m quiet and some DX coming through early from Eu stations. Nice to hear that again. 20m came alive and was pretty much the go to band for the majority of the day. I did check 15m a couple times but did not hear much and no one replied to my CQ’s.

In the middle of a QSO, my Jackite pole decided to collapse but I was able to finish the QSO with one end of the dipole about 4 feet above the ground. hi hi

The highlight of the day was my last QSO with EA3NO, Lluis in Spain. As the special station for the sprint there was a lot of competition but Lluis hung in there with my weak signal and pulled me out of the crowd after a couple attempts. THANK YOU FOR THE BIRTHDAY PRESENT Lluis!

Still wondering what a CPG is? Contest Point Giver! I am a really casual contester. Really the only reason I participate is that contests offer a fairly good opportunity to make some QSO’s. When you are QRP you have to do a lot of listening, plus pounce and search, but serious contesters will dig out weak signals to make the QSO’s so it is fun. I enjoy giving out points and reading the mail on ops that are faster than my cw comfort zone. Good practice, eh?

Here’s some photos from the day. Enjoy!

Duh: Learning Curve #3–Coke Choke Works!
Sep 9th, 2010 by kmack

Had a great time setting up the C Pole antenna in a tree suspended configuration. My good friend and cohort, Jim Diggs, K4AHO came by with his AIM 4170 Antenna Analyzer and we were ready to tune the antenna and get a feel for it.

LESSON: A good analyzer makes tuning an antenna fast, simple  and accurate! The AIM 4170 gave us a TON of info (most of it going over my head) and let us see how the C Pole was doing in several areas.  Take a look at this output! (Click on the image for a larger version)

LESSON: I followed Niel’s directions, but did not have a small plastic coffee container so used a Quart Coke bottle instead. So I call it a Coke Choke and it seems to work well. Here’s a photo to show it off!

I think this one is a keeper. Goes up easily, hears well and loads nicely too. I made a few brief contacts and called it a day, but look forward to more C Pole action in the days ahead.

T Time
Sep 6th, 2010 by kmack

Labor Day here in the USA! So a day to play for most of us. Depending on the weather I may get a bit more on air time, but I have a project lined up too.

Some time ago I purchased a Deluxe Tuner kit from Dan’s Small Parts and Kits aka a QRP Mini Tuner by Mark L. Meyer as described in a 73 magazine article. It is a nice little set of parts and a schematic for the price.

So I’m thinking this holiday might be the time to build that little T tuner out and see if I can load up the downspout that runs down the side of my back porch. I’ll let you know how it works!

Hope the bands hold up. Tonight’s QRP-L has a message from N4QA about how nice 40m is sounding right now! Sure would be fun to have our bands back from the QRN and low sunspot streak of late!
