MFJ 1788 loop contacts

I had some spare time today to put the MFJ 1788 loop to the balcony test once again. Up to this point I have not been able to make any CW contacts with the antenna. I was able to pull in some State side WSPR spots but that was it. I was coming to the conclusion that my DX was going to be Canada to U.S contacts. Today I set the Loop antenna for 15m and the SWR was great at 1.1:1. and up and down the band I went. I heard KP2/AG2J calling CQ at 21.025 and he was booming in here. I called out to him and low and behold he came back to me with a fast report! Fast report or not my 5 watts signal from the balcony just made it to the Virgin islands!! I then heard KH6LC from Hawaii..........but I was not able to make contact BUT for the first time I was hearing some DX stations. I then was able to contact PJ4LS with some repeats on my part but I still had my 1788 loop signal down to the Antilles off the coast of Venezuela!! The other station I heard but was not able to contact was ZZ80MT in Brazil. This was a good afternoon on the radio of me I was able to hear and make some DX contacts.

This happens to everyone else but not me…….

Iphone meets truck
To begin this is a post that has NOTHING to do with ham radio!  Getting that out of the way here we go……. It was a normal day at work and things seemed to be going just fine. We had our job given to use and it was not an outside job. That was great considering it was -20C and with the windchill -30C or more. So being indoors was a bonus, the idea was to pickup some coffee and head to our location. Once at our work site and in a nice warm building I noticed my Iphone was not clipped to my inside pocket! The first thing that came to mind was I left it at the coffee shop where I had it out checking email. Going back out to our truck my partner greeted me with an apology and showed me my Iphone…….it had been run over by our truck!!! It seems my 650.00 Iphone fell out of my pocket lined itself up perfectly with the trucks real
Otterbox defender case
tandem wheels and was run over! The phone was in a carry case called the  Otterbox Defender (don't work for the place or do they throw any money my way) When buying the case I was told it protects the phone in almost all situations.  This sure was a test and when I was given the phone it sure did look like it failed BUT I am thrilled to say the phone once removed from the Otterbox was in perfect shape and I mean not even a scratch. For those of you out there who have a smart phone ( not just Iphone) it sure is worth investing in a case (like the Otterbox) to save your investment from a potential disaster.

The captcha has finally arrived!

Out with the old
In the past I have posted my frustration with the captcha and how it was so mind bending and hard to read. Well someone in captcha world has just figured out that numbers can be captcha's as well and not the CRAZY letters we had to wrap our heads around. I would say for the last month I have been thrilled to post on blogs to find captcha's that are all numbers!! The captcha gods have heard and listened.
In with the new and may it stay!

The MFJ 1788 loop arrives!

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!

A warm day calls for mobile HF!

Setup in the car
Early in the week the weather was forecasting a warm (+8C) day for Saturday....rain but warm. Over the past week the temp's have been around -22 C without the windchill so a day of +8 that had to be a day to take advantage of outdoor radio!! Seeing that it was supposed to rain and it sure did I decided to go stationary mobile using my Elecraft KX3 and mobile mono band whips. Before going out I checked the propagation conditions and to my surprise 20m was not really the band of choice it seemed to be 15m. I did bring all my whip antennas but choose to put up the 15m whip to start. I setup in a small parking lot right on Lake Ontario. I was operating 5 watts QRP calling CQ as well going up and down the band for those calling CQ as well. I ran across HB9TNW in Switzerland calling CQ. I gave him a call and he came back to me. He gave me a 429 but that was fine with me for a QRP signal from the mobile. There was lots of fading in

and out on both our parts so the QSO did not last all that long but we were able to swap QSO details. I then moved over to 20m and was able to contact N4LTS who came back to my CQ call. Ray was in Florida operating QRP at 3 watts and I was still 5 watts. It was nice to have a QRPxQRP QSO. We had a good QSO for about 10 minutes and conditions started to change so we gave each other 72 and went on our way. That was more or less it for the contacts for the day but I was very pleased with the contacts that I had. I was also impressed while having a QSO with N4LTS there were some op's that came onto the frequency but noticing there was a QSO in progress they stopped transmitting and moved on.

Finally some WSPRing with the Alexloop.

A shot of the loop with the "T" fitting
I have been looking for a way to place the Alexloop  in the horizontal position as from my playing with the loop it seems to work better for me on the balcony in the omnidirectional horizontal position. Yesterday I was able to pick up a 1 inch "T" fitting mainly used for piecing together plastic pipe. I was able to feed the loops center support through the "T" fitting and place it nicely on the tripod. With just a little electrical tape to hold it in place it worked great. 
I finally set things up to get  WSPR up and going, so yesterday during the day and then into the evening I was WSPRing to see how my signal was getting out from the condo. Up to this point I have only used the Reverse Beacon Network or RBN which involved CW at 5 watts. I was not thrilled with the results and was really wanting to give WSPR a go. During the day I tried 10m and 20m I started out with 1 watt and in terms of WSPR that is some pretty high power. The antenna once again was the Alexloop in the horizontal position, at first attempt on both bands the Alexloop was indoors. It was not surprise that there were no spots at all it was time to move the loop out onto the balcony. Once setup I went back to 10m and it was about 2pm local time with no results again. I then jumped over to 20m and it was just U.S stations and very few I might add that received my signal. It was time to pack it in for the afternoon and some chores had to be done and I would get back on in the evening hours.
At 7 pm local time I was up and WSPRing on 40m and with great hopes as the band sounded good and I was decoding some WSPR DX such as EA3NEI. I once again was only heard in the U.S and this time I used up to 5 watts!! Maybe it was that conditions were poor out this way as they have been over the past week. Over the weekend if I get time I am going to give WSPR a go once again and see how it works out.

There is a chill in the air.

A view of Lake Ontario from the balcony
It's not news to anyone in North America that the temperatures sure have taken a dip whether you are in Canada or the south U.S. I was reading today that down in Myrtle Beach it was -4C, on the weekend the Green Bay Packers fans were freezing with the very low temps! This evening out this way with the wind chill it is suppose to hit close to -40C. By way of ham radio I am in the process of trying to Macgyver (referencing a TV show called Macgyver}something for the Alexloop to sit in the horizontal position on the tripod. This is only until the MFJ 1788 loop arrives. On Sunday I did manage to get the Alexloop on the balcony in the horizontal position.......for some reason that just does not sound right.......anyway I was able to get out on 40m but nothing on 20m. It was late in the evening and I was happy with getting some spots on 40m. It was a very short effort as the antenna was in a make shift setup for horizontal polarization...now that sounds better. For all you in North America stay warm and as for Europe I have been speaking with some of my blog bud's over there and the temps in some areas are balmy so enjoy those temps.
