Well, not really!

But as a reminder that this Saturday is Freeze Your Buns Off, he treats us to a flashback of the Flight of the Bumblebees from 2012.

Hey Rem …… how about a video of the Skeeter Hunt for 2013? (Hint, hint, hint, HINT!!!!!)

Yes, as a matter of fact, I do.

Compared to what it was before, the W2LJ basement shack is now pretty organized.  About a dozen large green garbage bags went out to the trash.  Some was mine; but a lot was some ceramic pieces that I had been storing for my Mom for the last nine years after she moved out of our house and into her apartment.  This shelf was totally filled with boxes of paints and ceramics – now it has radio and electronic items on it.

Those empty firelog boxes come in handy.  One is holding various empty enclosures that I have collected over the years.  The other has my collection of unfinished kits.  I have to sort through those and see if there’s any that I want to sell.  But parts tins, egg crates, rolls of wire and cable, cable ties, various parts and pieces all have a neat home now.

I have a relatively uncluttered operating space now; and my little tray table that I use for building is now uncluttered and very usable.  The World Map is new (and slightly smaller than the ARRL one that I had) as is the MFJ LED clock hanging on the wall.  My old Radio Shack one, which was about 20 years old was starting to lose some segments.

Down on the leg of the table is where I placed the new antenna switch.  The old one was on the wall; and I always had to lean forward to make an antenna selection change.  This is much better location now.

I would say that I am about 90% complete.  I need to go to Harbor Freight this weekend and purchase another 40 drawer storage cabinet like you can see in the lower left of the very top picture.  I have a lot of resistors, capacitors, transistors, etc that I have to sort, label and store.  That will take a while; but at least I have a functional uncluttered shack in which to do it now.

Before I left the shack for the evening, I disconnected the antennas from the switch. It reached 65F here today; but tonight we are expecting thunderstorms, 2 inches of rain and very gusty winds (maybe up to 60 MPH).  I don’t want to take the chance of either radio getting damaged.

My first Android app

I thought that some of you might be interested to look at the first app I have completed using Basic4Android (B4A) called WhereAmI. It’s no great shakes as an app, and I think there is at least one other in the Android Market that does a similar job. My app’s unique feature is that besides the locator it shows the national grid reference (NGR) as well as the Worked All Britain (WAB) square. WAB is a popular activity on the low HF bands over here.

Because NGR and WAB only cover the UK, my app will not be very useful if you are outside of Great Britain. Indeed the app will probably blow up if you try it outside the UK as I haven’t included any test that the user is within these sceptred isles.

I’d rather not say how long the app took me to complete, but it was far longer than expected given that I had already written code to convert from lat/long to grid locator in VOAProp. That code was in Pascal, and the trouble was caused by the fact that Basic4Android does not have equivalent functions to those in Pascal, or even Visual Basic, so I could not just do a copy and paste. In the end I found a conversion routine written in C++ and converted that to B4A’s dialect of Basic. From there on it was easy, as there is a user-written library in B4A to handle conversions to/from National Grid references, upon which the WAB programme is based.

If I don’t try something else I might have a go at displaying a Google Map centred on my location, as one of the examples that come with B4A does just that.

I don’t plan on publishing any of the apps I create in Google Market (or Google Play as I think they now call it). I am doing this just for fun. Think of this as the programming equivalent of those radio projects knocked together on a breadboard or built Manhattan style, with no expectation that they will get put into a nice box.

If there is any interest I will make available the B4A project files as a zip file so that folks can play with them, hack them about or use them as a starting point for something better.

I posted yesterday I had contacted F8EI and in the heat of the moment I had thought I contacted  him with between 20 and 14mW's of power!! I was thrilled when the contact ended and my calculations done it showed the distance at (I used the higher wattage of 20mWs) 181,958 miles per watt. I was thrilled and it was off to another contact to see what I could do for more miles per watt. On my Hendricks attenuator there is a bypass switch and I use it as the audio also is attenuated. I found another contact and switched in the Hendricks attenuator as I was transmitting I noticed the power output was around 150Mw's!!!! Did I read the meter wrong in my excitement.....I already sent an email to F9EI with the news of a 20mW contact. I was very discouraged not knowing what I was reading during the contact. Well 140mW's in nothing to laugh at and the miles per watt is still impressive.
Today I was looking through some recent photos on my PC of my shack setup as I wanted to change the wall paper on my PC at work. I was looking at pic's from yesterdays contact being the most recent pics of my shack. In one of the pic's was a shot of the rig and Hendricks attenuator, as I zoomed in on the attenuator the slider switches used to attenuate were not in the same position as they are right now! I had never repositioned the switches so I got to thinking Hmmmmm when I hit the bypass switch did I move the one attenuate switch that is out of position according the the picture?????. I turned on the K3 and moved the switch back to the position in the picture and took a reading on the meter and it was bouncing between 20 and 14mWs of power as the key sent out dits and dah's.
HOLY COW I did contact F9EI with (lets use the higher output) with 20mW's and I was not reading the meter wrong after all. It was me who inadvertently moved an attenuate switch to off along with the bypass switch. Just to test I checked the output with this attenuate switch in the off position (opposite of the pic I took just after the contact) and low and behold I was getting around 150mW's. Bottom line I really did make a 181,958 miles per watt contact!!!!

I took the test for my Novice license in November of 1978.  I received my ticket in the mail at the very end of December 1978.  I remember that I was sitting, taking a break from my job at the camera store where I was working.  We were having a post-Christmas sale and it had been a frantic day. My Mom had called to tell me that I had received the vaunted envelope from the FCC and that my call was KA2DOH. Between that time and my very first QSO, I was occupied with putting my station together.

For some reason, in my mind, I always remember my first QSO as having taken place on January 29th, 1979.  But a look in Logbook Number One reveals the date as January 28th, 1979 – so the 34th anniversary of my very first QSO was yesterday!

Yesterday when I got home from my failed out door op's adventure with KX3 I found out what I did. It was operator error on my part. The night before I failed to understand the KX3 charging procedure fully and I was rushing to get the battery charged for the next day. I thought I had put the batteries on a 16 hour charge by misunderstanding the simple procedure I inadvertently stopped the charge cycle. So in the morning I did try my KX3 on battery power and it did  not work but I discovered in the manual that the radio power on thresh hold had to be lowered when using NiMH batteries. I did this and the KX3 came to life. Little did I know that was all the life the batteries had in

It's charging!!

them most likely a very small factory charge.....Yesterday when I got home I looked over the instructions this time more slowly. As I went through each step at the end a time count down appeared along with "BAT CHG". I never saw this the night before! This meant is was WORKING and charging. New next few day here the temps are
going to rise into the +12C or more so I may take my KX3 into work and maybe get on 40m in the morning before I start work.
Today was a snow day for me here at VE3WDM we had a large and non forecast snow fall last night. I have over an hours drive to work on a good day and when I went out to the car at my normal 4 a.m ( not a spelling error yes 4.am) funny I call it the morning and others in my family call it the middle of the night.....I digress.....It was snowing like crazy and I did try to make it in but no roads were not cleared so it was to dangerous.
I got on the radio for some time today and snagged me some QRPp contacts. On 15m this morning I  heard Rudy IK4VFD calling CQ. He was in and out at times but I gave him a go with 500mW's of  K3 power and I got through to him!! He gave me a 539 report and did not seem to have any trouble getting through our exchange of QTH, Name, RST and a few pleasantries. I sent Rudy an email with more info about my station and the power that I was running as at the time I told him it was QRP. He got back to me with an email thanking me for our QSO. So that contact was 8467 miles per watt!!

I then found F9IE calling CQ from France and it sounded like he was just outside my window. So it was time to switch in the Hendricks attenuator and drop my power down to 150mW's. It took a few calls but Bernard was able to give me a report of 449 along with EU-064 as he is on Noirmoutier Island to boot!! So that contact gave me 24,261 miles per watt of a contact.
