Its always difficult to see a computer screen in bright daylight. Here in Florida, there are numerous pavilions with roofs over them and that helps a lot. Something extra is usually needed on a bright sunny day.  I had a pizza today and while I was waiting for it to come out of the oven at the Pizza shop, I asked the cook if I could buy a couple of extra boxes. I told her what they were for and she gladly gave them to me. The $4 tip didn’t hurt that situation I’m sure!

I’ll make the next one look prettier. 

I’m sure that I’m not the first one to come up with this idea. But here is my version of the Pizza Box Sunshade.

The interior of the box is pretty dark. Note the clear packing tape holding the sunshade together.

I did this job by myself, so I didn’t have anyone to hold the box in place while I applied the tape.

Using ordinary paper staples was a mistake, they leave sharp places to stab your fingers with.

Cheap and workable, the Sunshade should last a while. I’ll collect pizza boxes  to keep me supplied.

It took 3 Pizza boxes to make up this sunshade, and it was worth every bite of Pizza! 

I took this photo with a flash to show the interior of the sunshade.

My friend Matt, KB9UWU, eggs me on to buy things.  Sometimes I listen.  Sometimes I don’t.  But, eventually he wins me over and I’m usually happy with the purchase (e.g., K3 and Hex beam, although I built the Hex from scratch, which reminds me that I owe the blog a discussion of that).  I like to think that I let Matt be the early adopter and then pick and choose based on his experience.  He convinced me to buy a copy of N6BT’s book Array of Light.  Here’s my review.

If there’s anybody that knows antennas in the amateur community, it’s Tom Schiller, N6BT, the founder of Force12 and now owner of N6BT Next Generation Antennas.  He’s also a member of the very successful Team Vertical contest team, who have revolutionized DXpedition and contest expedition antenna systems by replacing trapped tri-band Yagis like the TH-3jr(s), TA-33jr, and A3S, with arrays of verticals located at the water line.  Schiller’s work has been nothing short of revolutionary so I had high hopes for the book.

My copy, like every other copy, is signed by the author.  It’s a good-quality laser print and has the same spiral binding as the Elecraft manuals.  The book is a loosely-edited collection of articles and clippings that read pretty well in series.  But, it’s bear to skim or go back to find specific things unless you’ve read the whole thing cover-to-cover a couple of times.  But, that’s pretty easy to do because Tom is a good storyteller.  My only other complaint is that there are a couple of places where I think Tom has drunk his own Kool-Aid regarding the efficiency of his antennas, especially “linear loading.”  This is a topic that I need to revisit with a pencil and paper study at some point because there is a lot of misinformation floating around about traps, linear loading, and “multi-monoband” antennas.  It’s not clear to me that anyone has sat down and really examined this in a methodical way.  It was disappointing that he quoted numbers like “greater than 99% efficiency” without going into more detail about the efficiency of a full-size antenna versus the linear-loaded one, etc.  Of course, this is difficult, but it’s something that always makes me a bit skeptical.

Array of Light is worth the price of admission for a couple of reasons—the first is the stories and the second is the antenna designs.  I’m a big proponent of not reinventing the wheel on most of my homebrew projects and this book is sure to provide some proven designs to work with.  Especially if you want a good discussion of practical antennas for DXpeditioning and contesting I think it’s a real winner.

1. Crystal oscillator for 98.5 MHz.  Check.
2. TUF-1 and TUF-3 mixers.  Check.
3. SMT protoboard.  Check.
4. MMIC amplifiers.  Check.
5. Larcan TV exciter amp.  Check.

Do you see what I see?  Yes, a 222-MHz transverter is on the horizon.

Guess the rude noise on 6m I recorded a little while ago but forgot all about

Guess the dinmap :: {skin:’black’, animate:true, width:’200′, volume:0.5, autoplay:false, loop:false, showVolumeLevel:true, showTime:true, showRew:true, downloadable:true, downloadablesecurity:false, id3: false}

I don’t often look for PSK warbles on 6m but am glad I did this evening. Obviously others were looking for someone as well I1YTO and I ended up having a brief QSO before he faded away again, up to 599 then down to nowt in a matter of seconds. Nice whilst it lasted

A couple of years ago I attempted to upgrade my rig to a more ‘vase’ station type. I really like my IC7000 and have thoroughly enjoyed using it but I have also enjoyed operating from larger rigs more. There’s less need to get a PC up and running and to use that to drive the menu’s. The reason why I didn’t get a new rig last time is because a more pressing need was there, we needed a new car.

Well now I get to think about it all over again. I’ve got a figure of around £1500 in my head and thought that the TS590 might do me well. Other options would be a second hand K3 but they are rarer than hens teeth and likely to be more money and an ideal would be a new Hermes SDR, but then again that would be more like £2000+.

I found this decision quite difficult before but the issue doesn’t seem to want to go away in a hurry. New or second hand I’m not really bothered. I just want the best I can for the money. HF & 6m are a must. 2m would be great and 70cm’s as well so i can do some satellite work but I’ll happily drop the VHF for a better HF rig. The TS590 does seem like the best choice so far.

The new edition of Radcom arrived a little while ago and I had a chance to have a read through it yesterday and there was a review for the new Kenwood super rig. It certainly looked an impressive site, but what struck me the most was not the features it had but the sheer cost of the thing. It tips the scales at over £6k. The cost of my last car!

Radcom also features a section every now and again about how they are trying to attract new members and potential people into ham radio. Can I give them a little hint, start working on cheaper rigs. The evidence was even strong as I went through the pages and it showed individuals, who know doubt deservedly, won trophies and prizes for all manner of things. There wasn’t a single one in the 16-24 bracket, in fact I’m pretty sure there wasn’t a soul under 45 in there.

Can I make a suggestion?

Can we please take a look at providing cheaper gear that doesn’t need building, say a £100 rig that will get people on air. If we can produce a funcube dongle for a little more than that which seems like an amazing piece of kit, why can’t we produce a rig that is universal, cheap, useful and worth having rather than producing for the wealthy ‘person of a certain age’. That way we may be able to see talent in the younger age bracket collecting trophies.

If you’re looking for a volunteer to project manage it then just ask. If you’re looking for a technical whizzkid then you’d better look elsewhere
