After many years as a stalwart Firefox user I have today made Google Chrome my default web browser.

I had tried Chrome once before. It was probably too early a version as I could not get on with it and missed too many of my Firefox extensions. Since then I have grown less dependent on those extensions and Chrome has become compatible with or has gained alternatives to those I need.

I installed Chrome a second time in an attempt to solve a problem that I thought was an issue with Firefox and turned out to be something else entirely! The installation was quick and easy. Chrome imported all my Firefox bookmarks with ease, reminding me to close Firefox so it could access them. I didn’t allow the installer to make Chrome the default browser initially, but after half an hour I was ready to take the plunge.

This won’t be news to those of you already using Google Chrome but the new browser feels much faster than Firefox. I see that 20% of visitors to G4ILO’s Shack are using the Chrome browser. I think it won’t be long until it overtakes the 27% of my visitors using Firefox.

My first K2 serial 6613

This week I posted a question on the Elecraft reflector "I'm building a bare bones Elecraft K2 radio and later will be putting it up for sale what kind of options would a buyer be looking for?" I had received many replies and all were very good but also got me thinking. I had always thought of the K2 as a CW radio (selfish me as I am a CW op) but one of the first suggestions was to make the radio both CW and SSB friendly by adding the SSB option. To me that should had a been a no brainier as that opens the market much wider to more potential buyers. I was then also reminded of the invaluable add on that I put in my K2 radio (which is still in my shack and goes out on park and car expeditions) the rework eliminators by unpcbs. These folks have
developed a kit that allows the K2 to be setup and ready for any add on you want to put in the K2. Let me clear the waters a bit......if you build a bare bones K2 with no options but later you want to add some options,  it my require you to  remove some components from the K2 in order to add the option.

With the unpcb kit  there is no de-soldering on the K2. In a nut shell you unplug the unpcb board and plug in the K2 option. There is another great advantage to this, if you think you have a defective DSP filter (or any other option) board you simply unplug the DSP filter and plug in the unpcb board and see if the problem is fixed. Its time for me get off my soapbox for the unpcbs folks.......but if you ever are thinking about an Elecraft K2 build this add-on is well than worth the money!!! I just have to jump on the soap box  for a short time again.....On the top of the noise blanker rework board you see some resistors. These resistor (or other components) would normally be on the K2 board and have to be de-soldered to instal the NB board option from Elecraft. With the rework board you unplug the rework board and plug in the NB board. If there ever is a problem with the noise blanker (or any other option the rework kit looks after) you unplug it and plug in the rework board. You K2 will now work but without the NB option. Without the rework board you would have to re-solder in the components you removed for the rig to function properly.

From the post I received great suggestions on options that should be added while building the kit. The one idea I am leaning toward is to just leave the radio "option free" and

when the kit is done ask potential buyers what they want in the rig. So it becomes a radio that is "made to order" The buyer will pay for the options they want and a small fee for assembly, setup and installation but in the end they will have a radio that is customized to their radio needs. It's the way I have always wanted a car purchase to be!! At this point the kit is going through the parts inventory.

I was busy writing the PW column this morning and doing some other work on the computer, so I didn’t set the 28MHz WSPR running until around 1330z. I was running 1W as per normal.

There are some nice west coast spots today – though they didn’t hear me – but good to have copied some W6/7s.

10m WSPR spots @ G4ILO 11 November 2012

Ten metres seems to have perked up a bit today, though conditions don’t seem as good as they were a week or so ago.

During the afternoon on PSK31 I heard, but didn’t work, Mexico and Panama. No WSPR monitors there so they don’t show up on the map.

Calling CQ resulted in contacts with some East coast USA stations. Propagation to Europe can’t have been that good. I think this is the first time that I didn’t get called by European and Russian stations.

I heard several USA stations working in a 10-10 contest. I don’t have a 10-10 number so I didn’t try to contact them. As a fan of 10m I like the idea of 10-10 but to be a member you have got to be sponsored by several existing members and then pay a membership fee. That’s way too much hassle and expense just to get a number to send people. The European PSK Club has the right idea. Membership is free to anyone and communication with members is via a web site.

Hello and welcome to a very late release of LHS Episode #093. Recorded about a month ago, I finally found the time to get this one edited and put out so the world can experience it. I’d like to thank our loyal listeners for their patience, and I sincerely hope that this episode stands up to the fine quality (*snicker*) that you’re used to from LHS. We get a visit from one of the show’s ambassadors in this episode who tells us all about his experience ambassadoring for a Linux event in Ohio. You know the one. Surrounding that are some interesting Linux topics, a ham radio discussion or two and a very informative bit of feedback from the Old Texas Engineer. You don’t want to miss it.

My article on the Android HT generated some interesting comments and ideas. Thanks so much! One of the main themes in the feedback is to have the radio be “faceless”, with the user interface done on a mobile device (i.e., smartphone or tablet). The mobile device would communicate to the transceiver via Bluetooth (or maybe WiFi). This approach has the advantage of separating the radio hardware (which probably doesn’t need to change very often) from the compute/display hardware (which is on a faster-paced technology path). I went ahead and hacked together a concept photo of such a device (click the photo to enlarge it). This device could interface with any mobile device that has a Bluetooth interface, so it would be independent of OS on the mobile device (yes, you could use your iPhone).

Such an approach opens up a variety of use models. Imagine sticking the transceiver in your backpack and using an app on your smartphone to enjoy QSOs when hiking. Alternatively, the radio could hang on your belt. At home, the radio could be left in some convenient location, connected to an external antenna on the roof and operated from the mobile device. (Low power Bluetooth is said to have a range of about 10 Meters.)  These are just a few thoughts…I am sure you can think of others.

I would expect the original Android HT concept to be easier to use for casual operation, due to the All-In-One Design with dedicated hardware volume control, channel select and PTT switch. I am assuming those functions would be implemented in software in the faceless implementation, which would likely be less convenient. Most mobile devices have their own GPS system included, so that would mean one less thing that has to be in the radio.

The other idea that surfaced in the feedback is using Software Defined Radio (SDR) technology to implement the transceiver. This would provide a higher degree of flexibility in generating and decoding signals, enabling additional areas of innovation. That is a great idea and will require a whole ‘nuther line of thinking.
