I’ve been thinking about buying an Amazon Kindle. But I’m not sure if it will really be useful for what I want or whether it will just end up sitting on a shelf like my Eee PC and other gadgets of the month.

I know that the real purpose of the Kindle is for reading electronic books purchased from Amazon.com. However I don’t see myself using it for that very much. What I am interested in is reading ham radio and electronics publications that are increasingly being made available in electronic format. Are these magazines viewable on a Kindle or do they use some proprietary format only supported by a special application that needs a PC or Mac?

One of the publications I’d probably use it for is CQ, as I’m not sure it is really worth the international postage. Then there is World Radio, which is only available in electronic form, which I have never read due to the inconvenience of having to use a PC to do it. Now ARRL is bringing out an electronic version of QST. I still look forward to the printed magazine landing on the doormat but I do pay quite a premium for that.

I’d be interested to learn from Kindle users what formats the device supports. A couple of months ago the back issues of the now defunct 73 magazine and Ham Radio were put online. I downloaded the Kindle application for Windows and was disappointed with the results. The magazines were available in Kindle format but it looked as if they had been badly scanned using an OCR system and half of the content was in Greek! The PDFs were huge files and looked more like a poor quality FAX. The best format appeared to be one called Deja Vue. I downloaded a reader for it. Does the Kindle support that?

My eyes might find it easier reading on a device that lets you zoom in and enlarge the font. Does the Kindle let you do that?

How well does the Kindle support PDF files? I expect I would use it for those a lot. With a Kindle could I read PDFs I’ve downloaded and stored on a drive on our network or a memory stick? I’ve often considered, for nostalgic reasons, ordering some electronic back issues of Radio Communication (now RadCom) from the years when I first got interested in ham radio, though so far I have always changed my mind when I see the cost!

So over to my readers. Your thoughts on this, if you would be so kind!

Next week a new semester is starting. They gave me more hours to teach, which means more income, but less time to spend on fun things. So I really wanted to finish another project and this week was just the time to do it: an audio filter. In my younger years one of the few kits I build was an notch/bandpass filter. Later I bought the Datong FL-2 and FL-3 filters I always thought it was a must to have one. Ever since I became a ham I thought about building one, but surprisingly there are not many design to be found on the interwebs. Elecraft sells a kit called the AF-1 and they were nice enough to put the schematics on their site. So I gathered the parts and put quite some hours of work in building it according to my own lay-out. The result……

It worked….sort of. But not as advertised on YouTube. I should have known better, so I cleaned up my desk and started anew. Neat and tidy this time and in modules. First up, the power section. Now, how about this?

That’s the way I like it. It worked first time, delivering 12 and 6 Volts. But I’m afraid this is going to be another long term project. Stay tuned.

By the way, after only 41 days I already achieved 25% in the FISTS 25th anniversary Prefix award. The goal is to make 25 CW contacts for each prefix number. Funny to see which number is most issued and thus easiest to score. “7 is up front with 11 entries, closely followed by number 3 with a very respectable 10 entries.” I really have to start looking out for more number six stations. If you have a 6 in your prefix then don’t forget to call me, please.

I’m just about old enough to remember to tie up my shoelaces in the morning (Although its taken me 2 days to remember that I broke my shoelace and as yet haven’t remembered to open the drawer and replace it with the one I knew I bought a while ago). So I can remember that its quite easy to ‘Just upload your photo’s’ to this site or ‘just back up every 10 minutes’ or other mundane tasks that your computer should do for you without even questioning it. In fact it should almost be law that stuff is backed up as soon as you put it on your PC without having to ‘Just set this or that up’.

Where am I going with this?

The answer is recently I found If this then that (ifttt) and have used it to do simple tasks like cross posting and other little tasks on web based systems that it current supports.

Another one I found is Dropbox automator which like the name suggests does stuff to folders and files in you Dropbox folder as soon as you put them in. A pretty handy tool for when, like me you need to re-size photos for putting in this blog, uploading documents to Google Docs and other little boring jobs.

Hope you get some use out of these services like me, now where’s that shoelace before I forget

So I missed a day – so what!

I got right back up on the horse and in the saddle via another great QSO with Jim W1PID on 80 Meters.  Jim was telling me that if the weather stays warm in New Hampshire tomorrow, that he just might experiment with  a kite antenna.  I told him to make sure to grab lots of pictures to post!

Jim has asked me how my KX3 “fever” was going.  I told him it was starting to climb and the only cure would be a package from Drs. Wayne and Eric.  I will patiently wait and endure, but the recently released eHam review isn’t making things easier.

I got the new QST “Antenna Issue” today and with interest I read the little blurb about QST going digital some time mid year 2012.  While all ARRL members will continue to get a paper version, the digital version looks to have a lot of potential. Links to videos and the like will be embedded and the plan is that the digital version will be compatible/readable from not only PCs, but tablets, phones and all sorts of mobile devices.

I guess it’s only a matter of time before paper periodicals become the exception rather than the norm.  I have downloaded and have read many books on my Kindle.  That was one of the best Christmas gifts my wife ever gave me.

Interestingly, I read an article on the InterWeb today where Apple might release the iPad3 on Leap Day. Supposedly the screen is so good, that it is being compared to the quality of a  printed page.  As much as I would like one, I can only afford one major purchase a year and the KX3 was it!

On a totally different note, because of how well it works on this laptop and on my Acer netbook, I have pretty much made Google Chrome my default Web browser.  It seems to be a lot quicker and responsive than Firefox.  I guess it doesn’t enjoy a lot of popularity, however.  When I look at my blog stats and I go to the “Browser War” section, Chrome places a distant third after Internet Explorer and Firefox.

Has anyone else noticed that the sunspot number has taken a dive lately?  Today it was 33 and it’s been a while since it was “up there”.  Hopefully this will be the quiet before a storm of good band conditions for the Spring and Summer.

QRP – When you care to send the very least.

And so my everyday streak comes to an end.

Yesterday was one of those days at work where you just want to dig a hole, jump in and pull the hole in after yourself.  And unfortunately, due to the wonderful world of cell phones and Blackberrys, it didn’t end once I got home.

Needless to say, when all finally calmed down around 10:30 or so, I didn’t feel like getting on the radio.  All I wanted to do was go to bed. And I did.

I tried raising V31JZ on 30 Meters tonight, after coming home from a slightly better day at work;  but I could not bust through the pileup before the witching hour came and 0000 UTC occurred.  So February 9th, 2012 goes QSOless.

So, what do I do?  Pick myself up, dust myself off and start anew.  This is one of those years, where if I still make a QSO for every day for the rest of the year, I can still honestly claim that I made a QSO for 365 days of 2012.

Are you planning to attend HamCation 2012 this weekend in Orlando, Florida?

Before you go, download this handy printable guide provided by the HamCation folks (shown below). Looks like it’s going to be a lot of fun. Cross your fingers that the weather holds out, but it’s bound to be better than our weather here in New England this time of year!

Don’t forget to visit our friend Ed Griffin from Wouxun.us.  He called this morning and said he’s going to be set up by the RV entrance and tells me that he’s got some great new versions of the popular Wouxun HT, the KG-UV6D-IC1 ($140) and KG-UV6D-IC2 ($150).

Ed said that as a bonus, if you stop by his booth and mention you saw this post on AmateurRadio.com, he’ll give you $5.00 off the purchase of a Wouxun radio. Save yourself the cost of shipping and get an extra $5.00 off a great radio at HamCation this weekend.

Everyone who commented to my last post about the lack of output from the Kits and Parts RF amp felt that the problem had to be the QRPer’s curse – the toroid inductor. Normally I don’t have a problem with toroids, but when they are so small that your thumb obscures the whole core while you are holding it, never mind winding it, they are not the easiest of components to work with.

So I gritted my teeth, tried to forget the hour I’d spent yesterday wrestling the thing into position, and yanked it out. One of the wires broke off in the hole leaving nothing to grab on to. I was unable to clear the small plated-through holes in any case. What I was able to do was melt the solder enough to push some bare wire through, creating “pins” that I could solder to. I twisted together the two wires that are connected so I had three ends to solder to the three pins I created. The toroid now stands up on the board a bit but it was easier soldering to the pins than trying to get four thin wires to go through four holes simultaneously. To my joy, on applying power and RF the power meter showed output.

I’m getting about 150mW if the amp is supplied with the recommended 8V, and just about 200mW from a 9V supply. That’s only about 10dB of gain, a bit less than expected but probably enough given that the Propeller does not generate the purest of signals. The WSPR beacon has already been spotted a few times in Germany. But the 2N5109 runs a bit hot to the touch so I’ll have to QRT until the heatsink I ordered arrives. In the meantime I still have the LCD UI board to assemble and play with.
