Print me an enclosure

Picture from nextdayreprap.co.uk

Jason, NT7S has just posted an article entitled “3D Printed Enclosures” on his blog. As a ham with a drawer full of unboxed projects who has often spent hours searching for suitable enclosures for a project and only finding ones that are either a wee bit too small or miles too big, the idea of being able to make my own custom enclosures is very appealing.

I had heard about 3D printing before, but thought it was either an April Fool spoof gone wild or one of those blue sky ideas that never become reality. My (admittedly cursory) searching has so far failed to turn up any articles that explain how it works, who makes 3D printers or what they cost. (However the site from which the picture was taken, nextdayreprap.co.uk, looks like a good place to start.)

A radio on every port

I left Faros running overnight. I needn’t have bothered: Nothing whatever was heard on the bands 14 – 28MHz from 1730 yesterday until 0730 this morning. Even now, the Finland beacon OH2B is the only one making much of a showing on the lower 3 bands, though there is a flicker of a signal from VK6RBP on 15m. I haven’t interrupted beacon monitoring to take a listen on 10m yet but prospects for the ARRL 10m contest don’t look very good.

I am going to have to interrupt beacon monitoring some time soon. I need to yank the shack computer out to install a spare 2-port RS232 board to give me two more real serial ports. I should have left it in instead of replacing it with the 4-port board whose four serial ports are now all used up (K2, K3, TM-D710 TNC for 2m APRS and TM-D710 Echolink control, since you ask.) I want to use my FT-817 for beacon monitoring as it is a bit of overkill to use my K3 for this, and the FT-817 CAT cable I have has a DB-9 for a real serial port. I could always use a USB to serial adapter of which I have three, or even make up a USB cable using a wire-ended USB-to-serial plug. But USB ports are in equally short supply, as you might imagine. Whilst the cover is off the computer I will take the opportunity to hoover out the inside which has an amazing ability to attract dust!

Being able to use the 817 for beacon monitoring won’t solve the conflict between monitoring and operating as I still have only one suitable antenna for both tasks. But it will allow me to give the K3 a rest!

I should practice what I preach…………

All is going well.....for now

Last weekend  I participated in the CQ WW CW contest and in a post just before the contest I shared some things I included and avoided regarding contests.  One would think that because it's my list and I was "preaching" about it on my blog that I for sure would be one to follow it.........WRONG and boy did I pay for it!! The contest was going along just fine the propagation was great, 10m was wide open and my QRP signal seemed to be getting out just fine. Now this being a CW contest and a world wide one at that I found the CW was being sent as fast as a bullet.  To copy these fast calls was taking more time than I wanted to
spend,  but the stations were much needed multi's or possible DXCC's. In the past this is were my trusty Elecraft K3 has helped me out. The K3 has the ability to copy code and scroll it at the bottom of my Elecraft P3.......but it was not happening and no matter what I adjusted I could not get the rig to read the code.         
Firmware download going well
It was at this time I started to wonder from my own advice........the downhill slide began with a question on the Elecraft reflector regarding my decoding troubles. The common answer that came back was that the latest firmware for some reason did not allow the decode to work. I was advised to download and install the latest BETA firmware (note....Beta firmware downloads are not as simple as production firmware releases) and all would be well. The slow downhill slide was gathering speed when I downloaded the Beta firmware to my PC's desktop. It sat there for some time as the dark side started to take a more firm grip on me!! I then unzipped it and say it ain't so but I began to download it into the Elecraft K3.

THEN IT HAPPENED

The red transmit light started to blink, the LCD screen went dark with a jaw dropping message MCU LD (LD meaning SOMETHING IS UP). In a dark empty space in my mind I heard my own advice "never update  your radio's firmware before (or during) a contest" I have done countless firmware updates and all have gone smooth.....but during the CQ WW CW contest NOT!!! So back to the Elecraft reflector and search the archives for hopefully the answer.  The answer was found and after an hour of @#$%%& and more #@*&& the K3 was up and running  and I was back in the contest and might I add
I HAVE LEARNED MY LESSON.........well until next time.......:)

No-IP Free

A few months ago I began using the No-IP Free service in order to be able to access my home network using a hostname or  fixed IP address. This worked well until a couple of weeks ago when I started getting the error “no host”. I logged in to No-IP and could find no reference to my account. So I recreated it with the same details and it is working fine again.

I vaguely recall seeing something to the effect that to keep the free account active you are supposed to log in once a month. The trouble is I find it hard enough remembering what day of the week it is never mind something like that. Previously I had used the DynDNS free service but that didn’t like the frequency with which my broadband changes IP address. My broadband provider says that I can only have a fixed IP address if I have a business account. It would be cheaper to stump up $20 a year for the No-IP Enhanced account. But being a dyed-in-the-wool cheapskate I’d like to avoid doing that. Any recommendations for free IP services that stay working as long as you want?

Back up on my captcha soap box

Some time ago I blogged about the Captcha's one would have to deal with when trying to leave a comment on some blogs.  Over time Captcha's have changed and not for the better. I can remember when they were simple......a pain but still simple to solve. Then I guess cyber bots became smarter so the Captcha's  became harder!!  The new Captcha's had a "wave" to them along with upper and lower case letters. Then as fate would have it the dam bot's did it again became somehow smarter....the Captcha's then had an UNCOOL way of blending their letters together and burring them to boot, oh and lets add numbers now too.
So my latest Captcha rant is......this week I was going to post a comment on a blog and on the comment page it contained the Captcha  along with the comment box. There was the blur, the wave and numbers as usual so I filled in the maze and then added my comment. I proceeded to hit the post button I was then informed my Captcha attempt did not match....surprise surprise!! I was instructed to hit the back button and try again. To my surprise my comment was gone and I had to start all over again!!! Is this the NEW Capthca....mess up and your punishment is to start all over again. I guess from now on I am going to  have to add but another step to my comment process, highlight and copy the comment in case I am punished and have to start again and maybe again and again....you get the idea.
I am stepping off my soapbox now........thank you.

Did you ever have “one of those days”

It's now Sunday and it's not been "one of  those days" BUT one of those weekends!!! Now that it's Sunday the frustration factor for me is just about blowing it's way through the roof  here. Maybe if I vent my weekend on the blog it will help level the playing field for me....oh and thanks for listening. Well Friday started off like any other Friday. I woke up to celibate the TGIF feeling, the weekend was here. My work day went well but it was after work that things when a little funky. After going to the gym I got back in my car to head home only to find I had left my Iphone and company cell in the change room. So back I went and both phones were gone!! I looked around in the change room and nothing, I checked with the front desk and no one had turned anything in. It was back out to the car thinking maybe they were in my gym bag or in the car somewhere. I ended up going back to the front desk at the gym to call my cell to see if rang in the change room. I called the cell and low and behold it started to ring at the front desk!!!! It was turned in and the young lady at the desk within all of 5 minutes forgot it was turned in
. Getting home I found the internet, home phone and cable not working. I called the provider, was on hold for over 25 minutes being told how important I was to them and to please hold. Seems there was a problem in the area it was being worked on. At this point thought I would work on my Elecraft KX3 movie with some final editing with Apples Imovie. Turns out you need the internet with Imovie to view the tutorials which I need so that was stopped as fast as it started. Since I was on the subject of the KX3 felt is was time to finish off the calibration of the rig. Well how do you think that worked out!!! Not so good the rig was calibrating transmit bias and was in some type of a loop were it would not stop. Oh well have to save that one for Elecraft Support on Monday. 
Endless calibration...that had 3 failed upload to blog attempts

Time to start dinner, went to open the cupboard under the sink......there was an smell coming from there like something had died. Turned out to be a leaking drain plug in the sink drain trap. The drain trap turned into an adventure.....purchased gaskets that were to small. Then I found the replacement drain plug complete with gasket......to good to be true drain plug turned out to be to big. Drain trap has to be replaced save that for next weekend, for now  put some silicone on the plug with a bowl under the trap.
Hey on Saturday the phones and cable were up and running but no internet. It was back on the phone to tech support and after unplugging and plugging things in and up and down stairs to the basement to the modem. The support came to the conclusion the modem was toast and so was I almost after all that running around the house.
Picked up a new modem at the cable store and hooked it up.....funny thing nothing in the house wants to connect up to the modem!!! Great back to tech support on the phone that for some reason now is NOT WORKING!!! Called them on the cell and they know about the phone troubles but the internet is good to go I was told.  Told her my troubles about getting on the net and the response was "I have no idea what's wrong" I was told I was not stating a problem to her just a statement....can you believe that!! To make a long story short I did it myself it turned out the modem and my Apple airport router did not like each other. With a few menu adjustments to both units they are fully in love with each other.
As I began saying today is Sunday and to not turn this post into a book not all adventures were mentioned. The lights in my radio room flickering, loosing my car keys while at the mall, dropping carton of milk at the grocery store (yes it went everywhere), leaving my debt card at the machine, taking a picture with my Nikon camera to have it display a message "all files are corrupt" then totally stopped working..... the list goes on. So it's now Sunday, Julie thought a nice trip to Starbucks with my laptop and her Kindle would be relaxing. That sounded great until the laptop decided to not start....nothing. When I got home I got the Linux CD out to see what I could do. I started the Laptop and it started just fine!!! I started and restarted that thing at Starbucks like 10 times and nothing it now works like a charm.
So how has your weekend been going???? To think it's not even over yet the adventure here at VE3WDM lives on.

Listening to my readers

My blog from the very beginning was intended to get ham radio and in particular QRP operating out there. I have gleaned the fruits of other blogs, the information, the challenges and the new understanding to certain areas of the hobby I never new existed. In my last post I floated the idea about linking social media to my blog. My intent was to increase the exposure of ham radio to even more readers. After numerous personal emails and comments on my AmateurRadion.com feed I have come to the understanding the only real exposure would be the strong possibility of Mal-ware being spread!! I have done some surfing of my own and it would seem social media on my site could be used by hackers to infect the site with Mal-ware . This Mal-ware could be spread to the readers of the blog by simply following a link on my site or social media sites.
I have listened to my readers and have taken down all social media anything from my blog. This blog is here for the readers to enjoy, grow in the hobby and share their information and learning curves with me and the other readers....It's NOT a place to spread computer virus's and to have readers who found the blog useful and entertaining at times to pack their I.P address and go elsewhere.
As of this posting VE3WDM'S QRPower blog is social media free. The readers have been heard and action has been taken.....continue to enjoy the blog.
