As I type this on my tablet, it is -2F (-19C) outside. The furnace is running its little heart out and I just can’t wait for the next utility bill. On second thought, instead of complaining, I’ll just be happy that it’s warm inside! Although I do get tempted every now and then to dream of what Amateur Radio goody that I could buy with the money that is literally going up in flames.

A little bird brought to my attention that congratulations are in order, as a milestone has been reached. Charles Moizeau, W2SH is celebrating his 80th birthday. Chas, as he is affectionately known, is a fellow New Jersey QRPer. He is very active and very successful in the QRP Fox Hunts. Charles is also quite active in NAQCC activities as well as being a regular check in in many QRP CW nets. Happy birthday, Charles, with wishes for many more!

Speaking of the Fox Hunts, last night was a success as I managed to work both Foxes. The surprise of the evening was working Dale WC7S in Wyoming on 80 Meters. Dale was at ESP levels for most of the night. I could tell where he was, but that was about it. Towards the end, the band started going long and Dale’s signal grew stronger. With less than 15 minutes to go, Dale actually approached 599 levels (I confess that I turned my AGC off, so that I could hear him better. I know ….. risky move!) and I was able to sneak into his log.

The QRP ARCI Fireside Sprint is this weekend. I might give it a go. I have never participated in it before, as it is an SSB sprint. But I do have a microphone for the KX3, and the weather outside is supposed to be less than stellar, so maybe I’ll try something different.

There is a bug in the new QRZ.com logbook. I cannot add an entry in the log, so a pop up message appear that told me something is wrong. I sent QRZ.com an email and they will try to fix the problem.

What about the new log book of QRZ.com? It looks good and what I like most: it shows the worked DXCC (countries) I started the QRZ.com log book in October 21 , 2009. 127 DXCC, while my own record is 130 since I started after a very long period of absence in 2008. Never mind, I am no real DXCC chaser after all.

This morning I was WSPR-ing on 6 meters, for perhaps winter Es. But no spots on 6 meter today.

The little project I have to homebrew an Azimuth and Elevation rotator has moved on a little. After spending countless hours researching the project I came across a couple of really useful resources. Firstly the Radio Artisan website has simply done the hard stuff with the codes and secondly Anthony Stirk, M0UPU has made a shield / board for easy interfacing.

I’ve ordered a board and will see what I can do with it once it arrives. Next weekend is SOS Radio Week so I’ll be hamming it up at St Bees Lifeboat station so I doubt I’ll get a chance to do anything but we’ll see.

I recently came across this iPhone app that generates Morse Code ring tones called…wait for it…Morse Code Ringtone. I’ve used some other methods for generating Morse ring tones but I’ve found this one to be particularly easy to use. The app costs $1.99 so it is quite affordable.

Well, there is one thing that is kind of tricky: actually getting the ring tone onto your iPhone. It appears that Apple has not made this very easy for app programmers, so it is a little tricky to do. The method I found to work is 1) use the app to create the ring tone on the iPhone 2) email it to my computer 3) save it somewhere on the computer 4) import it into iTunes using “File” “Add File to Library”. At this point, the ring tone should appear in iTunes and will be transferred to your iPhone the next time you sync.

After playing around with Morse Code tone and speed, I found that I really liked the sound of a 700 Hz tone sent at 30 wpm. My code speed is a somewhat reliable 15 wpm, so 30 wpm is well above my normal copy speed. Still, I like the sound of this quick burp of CW. I set up these short Morse bursts to indicate various messages:

CQ CQ  - default ring tone
TXT    - text message
VM     - voice mail
MAIL   - email message

You can play these ringtones by clicking on the name above, or do a right-click to download them to your PC. Windows Media Player can play these files, but it gave me an error when I tried it. I just clicked through and it worked fine.

But you should really get the app and create some ring tones of your own.

Ready for inspection

The MFJ 1788 antenna has arrived I ended up ordering it from DX Engineering and cancelling the order at the local ham store. DX Engineering had the antenna in stock were as the local store was not able to tell me when the antenna would be in….it seemed to be a waiting game. Once ordering the antenna DX Engineering had it at my door in 3 days! I can't say enough about the great service that was provided by DX Engineering. Now having said that……..I have been doing a lot of online reading about 1788 loop and how over and

Capacitor

Control box test

over again they arrived damaged or just not working. Looking at the loop it seemed to be in great shape and externally survived the trip ok. As I looked at the control unit I found one of the  push buttons not working! The  range button that changes the meter from low to the high wattage scale . I opened the control box as I also heard some "rattling" noise from within the unit as well. I found the switch to be defective and in need of changing, the rattling noise was from the battery holder. It was only held in place with two-side tape and as you guess it….there was no holding left on the tape. At this point I had a choice to make:
1. Send the control box back to either MFJ or DX Engineering for repairs?
2. Ask MFJ if it's possible to make the repair myself if they were to send me the part?
I settled on option 2 as I could still use the control box until the switch arrived and not be put on hold until control box was repaired or replaced. (note: I purchased DX Engineering's last unit)

Stepper motor

The control box failed the QC check it was now time to open up the antenna (a must according to magnetic loop user group) The visual inspection looked very good now time to power up the antenna with the control box. With the cover still off the 1788 loop I wanted to make sure the internal capacitor moved freely and stopped when full rotation was reached in both directions.
All was going well until the capacitor was rotating counter clockwise and it just stopped! I then rotated the capacitor in the clockwise direction and back counter clockwise and it worked just fine. After many back and forth rotations the capacitor never acted up…..maybe this was a one off. I emailed MFJ regarding the switch and they are going to mail one to me so I can do the repair. Next is to mount the antenna and see how it performs stay tuned!
