OK – so here’s the deal.  I mentioned that I wanted to come up with a drive-on support that will allow me to use my Jackite pole as a support for wire antennas for portable non-hike type ops.  What I used to use, when I had my Buddipole, was a 4 foot plank of oak.  I bought a threaded piece of 2″ pipe and a pipe flange.  I secured the pipe flange into the plank with screws.  When I got to a suitable spot, I would drive onto the plank, screw the pipe into the flange and drop the painter’s pole that I was using as a mast into the pipe.  Viola’ – instant Buddipole support!

The problem is the Jackite pole is a way bigger diameter than the painter’s pole – 2 3/4″ in diameter compared to less that 2″ in diameter for the painter’s pole.  The biggest diameter iron pipe that Home Depot had in small, pre-cut, pre-threaded pieces was 2″.  Not gonna work.

So I took my 4 foot plank of oak and cut it into two, more or less equal sized pieces.

Then using hinges, I reverted it back into a single 4 foot plank.  Seems silly doesn’t it, at first hearing?

Ahhhhh …. but there’s a method to my madness, because now I have a vertical section as well as a horizontal section.

I added two “U” bolts to hold the Jackite pole.  And here’s what it looks like “in action”.

Two things remain to be done. First, I want to replace the hex nuts on the “U” bolts with wing nuts.  This will make it easier to tighten and loosen in the field.  Secondly, I need some sort of “support strut” between the horizontal and vertical components.  I am not sure what to use. A strut like you would find in an old style attache case or an equipment case would be ideal; but I don’t know where you’d even go about buying case parts.  The only other thing that I can think of is buying a piece of aluminum stock and fashioning my own custom “strut”.  Anchor it on one member with a screw and allow it to swing, and cut or file a “hook” into the other end and let that come to rest on a screw inserted into the other member.

I don’t want to take a chance that a gust of wind could catch this and then either blow it back onto the Jeep or even worse, out to the side (taking radios and equipment with it!).

The easy answer is to just screw a shelf bracket in place.  But that would make this thing a permanent “L”. Right now it folds down onto itself, forming a nice 2 foot long piece that fits in the back of the Jeep quite nicely, not taking up a lot of space.  I definitely want this to fold for easy storage, but yet be strong and stable enough when deployed so that there will be no worries.

Any ideas?

It occurred to me the other evening that it might be fun to get the FT817 going on JT9. Many of my QSOs using the FT847 have been made using 5 watts or so, really there shouldn’t be much difference.

It was a case of ordering an interface lead from my G4ZLP interface unit to the data socket on the FT817 which was a modest amount.

After the lead arrived today, I connected it up and the rig would switch to transmit, but the tones were not transmitted. I soon found that I had to change menu 26 on the 817 to User-U from the default. Also in menu 38 on the rig, I turned off the filtering.

That was all that was required. I tried a test transmission from the FT817 and monitored it on the 847 – it sounded good. I’ve already some JT9 QSOs in the log and the 5W signal has been heard in North America.

JT9 and the FT817 ought to be a very good combination indeed.

You probably didn't know that April 27th, Samuel Morse's birthday,  is Morse Code Day and even if you did, my guess is that you forgot. So I have been pondering on how to celebrate Morse Code Day. What is the appropriate protocol for gift giving, celebrations, etc...?

A quick scan of the Hallmark Card site yielded no Morse Code Day cards. I suppose if there were any celebratory Morse Code Day cards they would be written in Morse Code characters, which non-Morse Code knowing people think is clever. The problem is we hear morse code, we don't write it. so it is painful to sound out the characters in your head to interpret the clever message, ....  .-  .--.  .--.  -.--   -- --- .-.  ...  .   -.-.  ---  -..  .  -..  .-  -.--  .-.-.-. Irritating isn't it. So I dimissed the card idea.

Then I went to the party supply store to see what party favors might be available, you know, Morse Code Day plates, napkins, forks, center piece ideas, little plastic morse keys and other morse related party items.  I was very disappointed at the selection. Basically there was nothing. When I asked for assistance, the lady looked at me as if  I had gone mad. "Morse Code Day, is this a joke? I insisted that there must be some unboxed supply of Morse Code Day merchandise in the back of the store. After a frustrating debate with the lady on the relavance of Samuel Morse, I thought I should leave before she called security.

Not to be discouraged, I went by the local bakery so see what Morse Code Day cakes they might have prepared in advance to beat the rush. Either I was too late or the baker forgot. There were no Morse cakes prepared, so I inquired about a custom cake. After I heard the cost of the cake, I realized what a waste of money that would be since there were no Morse plates and no Morse forks with which to enjoy the Morse cake with. How inappropriate.

Then I thought about dropping hints to my wife about Morse Code Day so that she might surprise me with a thoughtful Morse Code Day gift. But how? She probably has no idea who Samuel Morse is  and I'm  sure she probably thinks is "morris code" anyway. So I thought about starting a Morse Code Day awareness campaign with a public demonstration at the park, with news coverage, a collection of old code keys and even a "Learn Your Name in Morse" workshop. But then I thought of all the work that might be and it's very possilble the turn out might not meet my expectations and I would become frustrated. So like the other ideas, I abandoned this one as well.

Then I thought of getting myself a gift in celebration of Samuel Morse's creation, so what would be the appropriate gift? Obviously a morse code key would be appropriate. However before I even knew of  Morse Code Day, I had to self impose a "morse key in , morse key out" rule because of the space my morse key museum were taking up. I couldn't decide which key I wanted to sacrifice, so I gave up on that idea as well.

So what to do, no cards, no cakes and no keys. As I pondered the situation, I concluded to just forget about Morse Code Day, which is what most people do anyway.

For the last few weeks, when I browse the pages in G4ILO’s Shack using Google Chrome browser, they start displaying in a plain text sort of mode.

How pages look in Google Chrome

How that page is supposed to look

I think what’s happening is the CSS style sheet isn’t being loaded. So the pages are appearing without any formatting. But why? This doesn’t happen in Firefox. It didn’t used to happen in Chrome. And it doesn’t happen in Chrome after I clear the cache. After that the next few pages display OK until it eventually happens again.

Is it just me, or is this happening to everyone who visits my site using Google Chrome?

We sometimes on this show attempt to bring you interesting interviews with people who are both computer literate and ham radio literate at the same time. In this case, we bring a scholar, physics buff, aerospace engineer and brilliant guy, Steve Nichols (G0KYA), to discuss the science of radio wave propagation. No need to turn the show off before it even begins. Steve makes understanding the Earth’s atmosphere, its magnetic field, and a ton of stuff about the sun simple and approachable. No mind-bending equations, no physics lectures, just some great information for anyone interested in learning how a radio signal gets from here to there. A bunch of follow-up information in the form of books and Web sites are provided as well, links to which will be in the show notes, for anyone who wants to further their education. Thank you as always to our loyal listeners. Make sure to tell a friend next time you’re out for a cold one. The more the merrier.

Thought it was time this evening to power up the K3 and see what was on the bands. The software  I use is DXLab and it comes with a spot collector as it's called. I noticed a spot for AX7GN on 20m so I double clicked on the spot and the K3 magically was there! So here I am listening for AX7GN and yes there is a station there calling what sounded like CQ....or did I want it to be a station calling CQ? Well I hoped it was not little voices in my head talking to me. I heard nothing so I just put my call out there....and listened just maybe a little to intently. I did hear what sounded like VE? VE? By this time the APF was on the RF gain was being adjusted and the filtering narrowed.  I gave the call again at a deafening 5 watts!! Between the static and the ringing sound from the APF  I thought AX7GN was giving out what  "KINDA" sounded like my call.....or was it those voices again!! I passed along a 559 but did not hear much in return. To be honest I am not sure what the heck happened.....did I want to hear my call so bad that the static kinda sounded like VE3WDM?? For a short time I listened to the band and low and behold AX7GN was there and answering some U.S calls! I'm not going to put this one in the books as I am just not 100 percent it was just not the DX voices playing games with me. Has this ever happen to you??
